WEBVTT 00:00:00.400 --> 00:00:06.640 milliondoll PC. Our nickname for this 00:00:03.600 --> 00:00:10.719 wild nine server cluster with a combined 00:00:06.640 --> 00:00:12.719 two pabytes of Kiosia Gen 4 NVD storage 00:00:10.719 --> 00:00:18.080 has been causing some serious problems in our server room. Thanks to the 7 to 00:00:15.200 --> 00:00:24.480 8,000 watts of heat it kicks out, it got so freaking hot in here that we needed 00:00:20.320 --> 00:00:27.439 to cool our lab server room. And even 00:00:24.480 --> 00:00:31.199 with the setup we've got now, it's still a little toastier than we'd like it 00:00:29.039 --> 00:00:35.760 here. Of course, it is a lot better than it used to be, thanks to our proof of 00:00:33.520 --> 00:00:42.320 concept heat exchanger setup that we cobbled together with a pair of APC data 00:00:39.040 --> 00:00:44.800 center cooling towers that we found 00:00:42.320 --> 00:00:50.879 behind a local data center. In a nutshell, this one grabs heat that gets 00:00:48.559 --> 00:00:56.000 thrown out directly out the back of the million-doll PC. Then it pumps that hot 00:00:53.680 --> 00:01:00.480 water up here where a second cooling tower yates that heat out into the 00:00:58.160 --> 00:01:07.760 warehouse which we would have to pay to heat anyway. Hey, 00:01:04.519 --> 00:01:10.159 Alex. The issue is that our proof of 00:01:07.760 --> 00:01:15.360 concept here kind of introduced some new problems. For one thing, while this 00:01:12.479 --> 00:01:21.200 tower does an ungodly amount of cooling, it also takes up an ungodly amount of 00:01:18.080 --> 00:01:24.640 space. It's designed to go in between 00:01:21.200 --> 00:01:28.080 racks of servers to chill the air, not 00:01:24.640 --> 00:01:30.720 behind them, which is the other problem. 00:01:28.080 --> 00:01:37.040 We don't have separate hot and cold aisles in this closet we call a server 00:01:32.720 --> 00:01:39.680 room. So, our cardboard duct here is how 00:01:37.040 --> 00:01:46.439 we get the hot air to the radiators inside our cooling tower. At best, this 00:01:42.799 --> 00:01:49.759 is a phenomenal waste of space and at 00:01:46.439 --> 00:01:53.119 worst kind of a fire hazard. Which 00:01:49.759 --> 00:01:56.479 raises the question, why all of this 00:01:53.119 --> 00:01:58.960 when we could just attach our radiators 00:01:56.479 --> 00:02:03.119 directly to the back of the rack? It would not only get us our space back, 00:02:01.360 --> 00:02:08.239 but it would probably work though. Oh my god, it's leaking water. Oh Jesus. We've 00:02:06.640 --> 00:02:16.640 got all the radiators we could ever need. What could possibly go 00:02:12.040 --> 00:02:19.200 wrong? A lot. Just like a lot of segue 00:02:16.640 --> 00:02:23.120 to our sponsor, Nexigo. Their Tri Vision Ultra is a 4K projector designed to be 00:02:21.120 --> 00:02:26.560 easily set up anywhere thanks to its autoscreen detection and convenient grab 00:02:24.800 --> 00:02:29.959 handle. Pick one up today using our link in the description. 00:02:36.560 --> 00:02:44.080 With that said, the current setup is kind of working. The filter is 00:02:41.440 --> 00:02:49.040 filtering. The purge for the filter is uh please don't open purgeable. Oh my 00:02:45.840 --> 00:02:52.160 god. And our auto topup with that uh 00:02:49.040 --> 00:02:54.160 toilet float in it. Totally works. It 00:02:52.160 --> 00:02:58.959 doesn't leak either actually, which is great. So, we don't need to change 00:02:56.400 --> 00:03:04.640 anything major here. But what we are doing today is dealing with this pump. 00:03:01.519 --> 00:03:07.519 It is weak sauce and is made of cast 00:03:04.640 --> 00:03:14.239 iron, which not ideal in a mixed metal loop, even if you are using corrosion 00:03:09.680 --> 00:03:16.879 inhibitors, which we aren't yet. Yet. 00:03:14.239 --> 00:03:21.440 Yet. Are we adding that today? No. Oh, god. Jake. Well, once we prove this 00:03:18.560 --> 00:03:25.599 setup works, then we might. Um, wait. What are you doing? I'm undoing this so 00:03:23.120 --> 00:03:28.239 we can put the new pump in. Have you considered maybe we should like 00:03:26.800 --> 00:03:34.640 disconnect it down there so it doesn't just spill water all over everything? 00:03:31.879 --> 00:03:38.319 Sure. All right. Oh, Jesus. Well, what did you think was going to happen? 00:03:36.400 --> 00:03:41.680 Water, J. You still continue to do the thing I said you shouldn't do. That's 00:03:40.080 --> 00:03:45.040 what I I thought maybe you would think about what I said instead of just 00:03:43.440 --> 00:03:49.840 continuing to do the thing you shouldn't have done. Okay. There's only an electrical box right down there that it 00:03:48.239 --> 00:03:53.760 pours directly into. Oh, not just an electrical box. The electrical box. The 00:03:52.159 --> 00:03:58.000 whole electrical room for the building. Yeah, it's down there. Um, now the 00:03:56.239 --> 00:04:01.599 flanges I originally ordered for this project finally showed up. Uh, you see 00:03:59.760 --> 00:04:05.200 they have a valve on there so you can isolate the pump. Oh, that's downright 00:04:03.280 --> 00:04:08.799 useful. That would have been great at a couple minutes ago. Yeah, we could swap 00:04:06.799 --> 00:04:12.480 it or we could just stick that one right back where the old one was. Yeah. Okay, 00:04:11.040 --> 00:04:18.320 cool. While we're throwing this in is as good a time as I need to talk about the pump upgrade. Not only are we going to 00:04:16.079 --> 00:04:23.360 stainless steel from cast iron, but this thing is about a sixth of a horsepower. 00:04:21.280 --> 00:04:29.120 So, to put that in context, it'll do about 25 gallons per minute with 10 feet 00:04:26.960 --> 00:04:33.479 of head pressure, which is about double what you'd get out of a typical garden 00:04:30.720 --> 00:04:38.080 hose. Oh, yeah. There she goes. Now, I was joking in the intro, we 00:04:36.160 --> 00:04:42.479 haven't actually cut anything in these towers. And then Justin just informed me 00:04:40.320 --> 00:04:47.919 that we can't cut anything in the towers yet without getting the door off, which 00:04:43.759 --> 00:04:50.320 is conveniently locked. 00:04:47.919 --> 00:04:53.440 This is looking very successful. 10 out of 10. Should we just use a 00:04:54.199 --> 00:05:00.320 drill? How does this work? Oh, what is 00:04:57.680 --> 00:05:05.280 this? There's a button. Oh my god, there's a button. We are just actually 00:05:02.000 --> 00:05:08.280 so stupid. We're so Yeah, we're so 00:05:05.280 --> 00:05:08.280 stupid. 00:05:13.600 --> 00:05:20.160 Oh my god, they're torques. Why are they Torx? Fortunately for us, you can get 00:05:18.240 --> 00:05:23.759 extra screwdriver bit sets like this torque set for the LTP store 00:05:24.440 --> 00:05:30.800 screwdriver. Nice. So, these radiators are a little 00:05:28.960 --> 00:05:34.400 weird. There's three connections. I'm assuming it's like this is the inlet and 00:05:32.800 --> 00:05:37.759 then we have two outlets. And I'm like, okay, let's let's measure these pipes 00:05:36.160 --> 00:05:44.880 and I can go buy some of the fittings ahead of time. This is like 3/4 of an 00:05:40.320 --> 00:05:48.160 inch on the outside. This is like 7/8. 00:05:44.880 --> 00:05:51.240 And this is like 3/4. So I probably need 00:05:48.160 --> 00:05:54.199 7/8 and 3/4 copper fittings, right? 00:05:51.240 --> 00:06:01.120 Wrong. The copper fittings I need are 5/8 and 3/4. Why? I don't know. Well, it 00:05:59.199 --> 00:06:04.319 turns out 5/8 copper pipe is not a type of pipe you use for plumbing. So the 00:06:02.639 --> 00:06:07.680 plumbing guy was like, 5/8? Why do you need 5/8? We don't we don't sell that. 00:06:06.000 --> 00:06:14.560 You have to go to an HVAC store. That's a refrigeration size. Luckily, I found a 00:06:11.759 --> 00:06:19.520 plumbing HVAC store that sold both and they happen to have the fittings that I 00:06:16.240 --> 00:06:20.960 need. These are 5/8. And if I look if I 00:06:19.520 --> 00:06:27.400 if I measure them with the fancy calipers here, 00:06:24.360 --> 00:06:30.479 0.76, and 00:06:27.400 --> 00:06:32.479 0.7 675, 772, depending on where you 00:06:30.479 --> 00:06:36.560 measure. Nothing a little solder can't fill. Starting with the inlet. Now, if 00:06:34.639 --> 00:06:40.479 we look at the fitting here, we've got almost the amount we need. I I can't 00:06:38.639 --> 00:06:43.520 make it work over here. So, we're going to leave this solder joint in here and 00:06:42.639 --> 00:06:49.039 then we're going to try to put the fitting on the top. I'm hoping we can get like a tiny bit more straight 00:06:46.319 --> 00:06:55.440 section. So, to try that, I'm going to heat it up and then Justin's going to 00:06:51.680 --> 00:06:55.440 try to bend it. Like, we don't need 00:06:56.600 --> 00:07:03.440 much. It's just elongating it. 00:07:01.280 --> 00:07:07.720 Like, see, it's just like squished. Oh, no. Probably just made it worse. 00:07:05.520 --> 00:07:11.520 Probably. This is definitely This is definitely not 00:07:09.680 --> 00:07:16.080 better. It is actually worse. Why don't we just try cutting that off and just 00:07:12.960 --> 00:07:19.960 see how it looks? Sure. Sure. You want 00:07:16.080 --> 00:07:19.960 to grab a sawzaw? Yeah. 00:07:21.880 --> 00:07:28.400 Hey. Yeah. I'm sure it'll fit right on 00:07:25.520 --> 00:07:32.400 there. This is not going to leak. There's no way this is going to leak. 00:07:30.319 --> 00:07:36.720 Wow. That is That's uh at her there, bud. For real, dude. Look how mint this 00:07:35.199 --> 00:07:41.520 is. I don't want to keep doing this. This is making it worse. It's very important to make sure you clean your 00:07:39.599 --> 00:07:45.440 definitely not destroyed copper pipe before you solder as otherwise the 00:07:43.840 --> 00:07:48.639 solder won't stick. I had a really stupid idea that I think is maybe 00:07:47.120 --> 00:07:52.880 actually not that stupid. I was trying to find something that would fit like 00:07:50.560 --> 00:07:55.039 the exact or close to radius. And look at 00:07:59.560 --> 00:08:04.639 that. A whopping I don't want to think 00:08:02.639 --> 00:08:09.000 about how much longer later. We've hammered a socket in which mostly 00:08:06.479 --> 00:08:13.919 reformed this one. The other radiator looks almost spot on. This one not 00:08:11.759 --> 00:08:17.800 great, but I can at least force a fitting on there now, which means we can 00:08:16.800 --> 00:08:22.879 solder it. Will it leak? Probably. But that's a 00:08:21.680 --> 00:08:30.360 problem for later, Jake. I'm going to put some flux on here, which will clean 00:08:24.800 --> 00:08:30.360 the part up when it's heated up. 00:08:33.120 --> 00:08:38.880 Both of our radiators now have fittings soldered onto them and hopefully don't 00:08:37.120 --> 00:08:43.200 leak. But that's not something I want to just gamble on. So, I wanted to find a 00:08:41.360 --> 00:08:46.560 way that we could leak test it. And I've got this little leak tester, which is 00:08:44.880 --> 00:08:51.040 literally just an air pump with a gauge. So, you hook it up, pump it up, and that 00:08:49.200 --> 00:08:57.279 gauge will show your pressure. We spray some Windex on there. It's all pumped 00:08:53.399 --> 00:08:59.200 up. But, if we look, our solder joint 00:08:57.279 --> 00:09:04.600 looks clean. Ignore all the bubbles from the plastic. That's unrelated. 00:09:03.360 --> 00:09:10.880 No bubbles. They're not 00:09:07.959 --> 00:09:14.399 pretty, but they don't leak. And that's good enough for me. Looks like you guys 00:09:12.640 --> 00:09:17.519 already cut this out. Yeah, we tried to find the ones that were the least 00:09:15.839 --> 00:09:22.399 disgusting, and it seemed like the top ones were the least corroded. So, we 00:09:19.440 --> 00:09:26.160 destroyed two towers. Okay. Well, this looks great. But I do have a question. 00:09:24.480 --> 00:09:30.160 Is there a reason that we're salvaging these radiators rather than just using 00:09:28.800 --> 00:09:35.600 radiator doors? It's like those are totally a thing, brother. I tried. They 00:09:33.680 --> 00:09:39.200 either just like stopped responding to my messages, didn't respond at all in 00:09:37.600 --> 00:09:45.279 the first place, or were like, "It will be $60,000." 00:09:41.680 --> 00:09:48.000 Oh. And then I remembered we had this. 00:09:45.279 --> 00:09:52.000 And this is more fun. Cool. Yeah. Time to build a water door. At least it's 00:09:49.600 --> 00:09:56.360 more fun right now. We haven't got to the part where there's problems yet. And 00:09:53.920 --> 00:10:00.480 build a water door. I shall. At least in theory. Now I'm 00:09:58.959 --> 00:10:03.600 working on how we're going to lay this stuff out. The bottom and the middle are 00:10:02.240 --> 00:10:08.959 going to be very easy. We're just going to use these 3/4 NPT to 3/4 ID barbs. So 00:10:07.519 --> 00:10:12.080 they'll just twist on. The top connection on each radiator is a little 00:10:10.560 --> 00:10:16.560 bit more complicated because we need to connect it to the bottom one. So what 00:10:14.560 --> 00:10:23.120 I'm thinking I'm going to do is use one of these T fittings and then a right 00:10:19.120 --> 00:10:25.120 angle. We'll use that kind of like this. 00:10:23.120 --> 00:10:28.959 And then this guy will go kind of like that. So, we can have this tube come off 00:10:27.120 --> 00:10:33.320 and connect to there. And this one's already connected. And then we just have 00:10:30.320 --> 00:10:35.279 one feed in for each of our 00:10:33.320 --> 00:10:41.200 radiators. It just looks like a normal barb, but spin it. Yeah. Oh. Ooh. It's a 00:10:38.399 --> 00:10:46.560 swivel barb. It's exactly what I needed. And it was $11. 00:10:43.760 --> 00:10:50.480 Really? Yeah. That's not bad. Green line hose and fitting, baby. They have 00:10:47.920 --> 00:10:55.360 everything. Oh my god. And I just ruined them all. That's my job. Yeah. Okay. How 00:10:53.519 --> 00:10:59.360 does this help us again? Because the door has to move and we can't just rely 00:10:57.200 --> 00:11:04.160 on like a rubber hose bending back and forth. We'd have to leave a ton of extra 00:11:01.279 --> 00:11:08.079 to make that work. Got it. No, that's got to go down this way. Okay. What if 00:11:05.440 --> 00:11:11.600 that went here and I go in there and then it went going to hang. I mean, I 00:11:10.000 --> 00:11:16.079 guess we could do it like down like that maybe. Oh, yeah. That's it's pretty 00:11:14.640 --> 00:11:22.360 I don't have a nipple either, so I don't know if we can do that. 00:11:17.920 --> 00:11:22.360 Yeah. Don't. I swear to God. 00:11:23.040 --> 00:11:28.560 There are large tools here and he is one of them. No, we don't need this. But 00:11:27.360 --> 00:11:31.600 that's doing the same thing. Yeah, but it's in a dumb spot, though. Why is it 00:11:30.399 --> 00:11:38.000 in a dumb spot? Cuz it's better to just have it all in one place and then we just run tubes everywhere. Why? Cuz it's 00:11:34.959 --> 00:11:39.440 easier. It doesn't seem easier. And then 00:11:38.000 --> 00:11:42.279 this Why do we need to go to the bottom of this rad to the bottom of the other 00:11:41.440 --> 00:11:47.120 rad? Because because let's say the other one 00:11:44.560 --> 00:11:50.880 has already been done like Oh, okay. That already has a T on it. Yeah. Well, 00:11:49.040 --> 00:11:54.920 wait. Why are you even proposing a new solution when you already solved it 00:11:52.320 --> 00:12:00.720 already? I'm trying to tell you this. But you don't listen. 00:11:59.120 --> 00:12:05.200 He's giving me a hard time, but he's the one who went to the plumbing store and came back with no nipples. How do you 00:12:03.760 --> 00:12:10.959 manage that? Well, I didn't need a nipple because I had this excellent plan that you've now changed. 00:12:09.600 --> 00:12:14.639 So, we're going to have our two hoses that come off of the tubing that's in 00:12:12.639 --> 00:12:18.800 the building, like the PEX tubing, go to here and here. This will be our outlet. 00:12:16.639 --> 00:12:23.279 This is our inlet. From our inlet, it gets split only once, which is nice. 00:12:21.760 --> 00:12:29.440 It'll go right to this input, and then a tube will come down over to here. And 00:12:26.160 --> 00:12:31.920 then the other side, the outlet, it gets 00:12:29.440 --> 00:12:37.760 really freaking awful fast. We'll have our input splits right here into this 00:12:34.000 --> 00:12:38.760 guy. And then it comes down into here. 00:12:37.760 --> 00:12:44.440 Splits again into this guy in here. Plugs into 00:12:41.680 --> 00:12:47.839 here. Splits again down to there. When you're doing something like 00:12:46.320 --> 00:12:51.440 this that's a permanent installation. There's a much better type of hose clamp 00:12:49.680 --> 00:12:55.279 that are constant pressure ones where it's just like a giant spring. These 00:12:53.200 --> 00:12:58.079 ones are fine, but they can loosen up over time, especially in an environment 00:12:56.720 --> 00:13:02.959 where there's like a lot of vibration. While Linus works on getting the fittings for our leak testing thing, I 00:13:00.880 --> 00:13:06.720 am screwing the radiators in. They luckily have a nice like L channel on 00:13:05.200 --> 00:13:10.240 one side which we can just screw directly through the door to hold the 00:13:08.639 --> 00:13:15.440 one side and then on the other side we're going to use these mounts that Justin 3D printed along with T-nuts that 00:13:13.440 --> 00:13:19.839 are really meant for 8020 but have a really nice flat face which should hold 00:13:17.360 --> 00:13:24.800 nicely against the grid and that'll hold the other side. This is a big moment. 00:13:22.720 --> 00:13:29.440 I suspect there will be at least one place that is leaking. You know what? 00:13:26.959 --> 00:13:33.839 I'll take that bet. I No leaks. Oh, what? I say no leaks for lunch. Uh, I 00:13:32.560 --> 00:13:38.880 don't know that I would bet anything on it, but I say no leaks. Really? Yeah, 00:13:36.320 --> 00:13:45.279 dude. There's no way. Do you remember last time doing that the the first 00:13:42.639 --> 00:13:50.079 setup? Oh my god. I do. Oh, I found a leak. Shoot. Exactly on where the Teflon 00:13:48.399 --> 00:13:54.480 tape got all crumpled like I was just saying. Dang it, Jake. We're going to 00:13:52.240 --> 00:13:58.560 have to do a lot of removal of things to get at that. Yeah, that's the worst 00:13:57.120 --> 00:14:04.320 possible place it could have leaked is right there. That sucks. But hey, at 00:14:02.480 --> 00:14:09.440 least we're doing this now and not when it's full of water next to a bunch of 00:14:06.000 --> 00:14:10.959 servers. Oh, hold on. What's this? I 00:14:09.440 --> 00:14:16.000 think we got another one. Same thing. No, no, no. We got another one. 00:14:14.079 --> 00:14:20.399 Upon closer inspection, it appears that when we bent this thing, we made like a 00:14:18.240 --> 00:14:26.160 little hairline crack in that very bottom tube, which sucks. I don't really 00:14:24.000 --> 00:14:30.880 want to redo all of this at this exact moment. So, I'm going to try and just 00:14:28.639 --> 00:14:34.399 put some solder on it and hope that that holds. I already like scotchbrighted the 00:14:33.360 --> 00:14:39.360 hell out of it, so it's clean. I'm going to put some flux on. And 00:14:37.000 --> 00:14:43.279 now we get to find out if this is going to work. There was like the tiniest 00:14:41.440 --> 00:14:46.560 little bubble on this fitting. So, I tightened it a little bit more because 00:14:44.639 --> 00:14:52.800 it wasn't quite as in as some of the other ones. And I think we're good. It's 00:14:50.480 --> 00:14:57.440 been like 5 minutes already and this dial has not moved at all. And I don't I 00:14:55.440 --> 00:15:02.720 like Windexed all the fittings again and I don't see any leaks. We might be okay. 00:15:01.440 --> 00:15:07.199 Fast forward a little bit and I've mounted the plastic side bracket 00:15:04.560 --> 00:15:14.360 thingies on and we now have a water door which I've been told is just a rack door 00:15:09.600 --> 00:15:18.000 with radiators on it. Surprise. Look at 00:15:14.360 --> 00:15:20.320 that. It holds. What a monster. Although 00:15:18.000 --> 00:15:23.760 with no water in it. Now you might be wondering what are we going to do about 00:15:21.519 --> 00:15:27.600 all of this extra air flow? cuz ideally we want any of the air from the servers 00:15:25.839 --> 00:15:31.040 to go through the radiators. For now, we're just going to use tape, but in the 00:15:29.120 --> 00:15:37.120 future, I'm thinking we could 3D print a little like angled piece kind of like 00:15:33.680 --> 00:15:38.639 there and kind of like there to duct the 00:15:37.120 --> 00:15:44.160 air into the radiator kind of like a velocity stack 00:15:40.440 --> 00:15:46.079 would. Pretty mint, right? Yeah. You 00:15:44.160 --> 00:15:49.360 going to cut this off? It's blocking air flow. I You mean you complain about my 00:15:48.079 --> 00:15:52.759 tape drop, but then you don't cut that off? Well, this is blocking air flow. 00:15:51.759 --> 00:15:58.480 This is sentimental. Oh yeah. 00:15:55.160 --> 00:16:00.639 Hi. Oh, okay. I'm really glad I put 00:15:58.480 --> 00:16:04.160 valves on that. If all of this hasn't made a ton of sense to you yet, 00:16:02.480 --> 00:16:08.880 hopefully it makes a little more sense. Now, we have our rack here. This is the 00:16:06.480 --> 00:16:14.320 back. So, back here, all the servers, they're blowing a bunch of 00:16:11.000 --> 00:16:16.079 air and it's hot. So, we're going to put 00:16:14.320 --> 00:16:20.199 our radiator door here. And hopefully the idea is the water going through it 00:16:18.720 --> 00:16:24.720 at like 20ish°ish will catch the heat. And then 00:16:23.120 --> 00:16:28.639 once the air goes through it, it should come out colder. And instead of using 00:16:26.800 --> 00:16:34.399 that giant tower over here with all the cardboard and stuff, the whole unit only 00:16:30.880 --> 00:16:36.399 takes up about this much space. So we 00:16:34.399 --> 00:16:42.120 save space. It'll probably work a bit better because it's closer. And um it's 00:16:39.759 --> 00:16:47.839 just freaking cool. Hey. Holy dude. Oh, okay. So, 00:16:45.440 --> 00:16:53.279 here's a really The air comes through. It is 00:16:51.279 --> 00:16:59.040 maybe not strong enough to do this on its own. We might need to add fans. This 00:16:56.959 --> 00:17:02.880 is a bit of a crazy concoction, but we've got a 1-in PEX fitting, which is 00:17:01.279 --> 00:17:07.039 the same size as this stuff here. It's PEX plastic tubing. And then it gets 00:17:05.280 --> 00:17:10.400 reduced down to 3/4, which is the same size as this. And then we've got a 00:17:08.480 --> 00:17:14.160 swivel fitting. Kind of one leg there, and then one leg there. And then we'll 00:17:12.319 --> 00:17:18.959 run our rubber hose from here to here and hopefully it just works. Previously 00:17:17.120 --> 00:17:23.280 we were using fittings called shark bites which are kind of like a easy 00:17:21.439 --> 00:17:26.799 solution where they have like O-rings and it's like a self you just quick 00:17:25.199 --> 00:17:31.360 disconnect push it in there but I'm switching them up to crimps which use a 00:17:28.799 --> 00:17:35.280 metal ring around the pecs and then you crimp them on with a tool and it 00:17:33.200 --> 00:17:39.840 compresses the plastic together. In theory a much 00:17:36.919 --> 00:17:45.360 more secure connection. We're going to have to find out. A little bit top, but 00:17:42.080 --> 00:17:45.360 nothing crazy. And then 00:17:47.400 --> 00:17:52.919 open. Ah, it's swiveling a 00:17:50.760 --> 00:17:57.360 little. Let's um add a little bit of water. I guess 00:17:55.840 --> 00:17:59.880 Jamie turned on the water. So, we're filling 00:17:59.880 --> 00:18:05.600 up. So, this is just room temperature 00:18:02.880 --> 00:18:09.760 water, right? We're cooling it with the air in the warehouse, which is around 00:18:07.440 --> 00:18:15.360 20°. It's so weird to stand behind this and 00:18:12.240 --> 00:18:17.280 the air coming off it now to be cool. It 00:18:15.360 --> 00:18:20.000 actually feels like colder than the room in here. 00:18:20.120 --> 00:18:26.160 Honestly, that's weird. That's so 00:18:24.039 --> 00:18:33.280 weird. And then you open it up and you're like, "Oh god, it's so 00:18:29.400 --> 00:18:35.520 hot. I suspect we're like cooking inside 00:18:33.280 --> 00:18:39.320 there." But then again, the servers are taking in fresh air. 00:18:39.679 --> 00:18:47.039 I don't know. Maybe it's fine. Got John here, our test technician 00:18:44.799 --> 00:18:51.200 extraordinaire, god of numbers. That's awful, right? Yeah. That's like like 00:18:51.320 --> 00:19:00.039 putrid, right? You actually like kind of feel 00:18:56.640 --> 00:19:02.039 it's almost a little cold coming off of 00:19:00.039 --> 00:19:06.559 it. Like shockingly working. You've seen a little 00:19:04.880 --> 00:19:11.360 bit of this, right? Yeah, a little bit. How well do you 00:19:08.240 --> 00:19:12.720 think this is going to work? Uh, you 00:19:11.360 --> 00:19:18.320 know how hot it was in there with the other cooling tower in there, right? You can feel it already kind of. Yeah. Yeah. 00:19:16.160 --> 00:19:22.160 Okay, come on. So, let's let's take a sample. Stand behind the thing. I know 00:19:20.880 --> 00:19:28.080 it's weird. There's so much space in here. Awful, right? Like actually 00:19:24.799 --> 00:19:28.080 horrible. Stand behind the 00:19:29.240 --> 00:19:35.919 thing. Like, it's cool. Oh my god. What? 00:19:33.360 --> 00:19:39.960 What did you do? I don't know. Yeah, I know, right? Oh, yeah. Yeah, 00:19:40.160 --> 00:19:46.000 we made our little double fan stackeroonis. These are Noctu industrial 00:19:43.840 --> 00:19:50.000 30,000 RPM fans. They're called industrial because they're meant for 00:19:47.600 --> 00:19:54.720 industrial. This feels industrial, right? I think this is a reasonable use 00:19:52.080 --> 00:20:00.720 of these. Um, I don't have enough of them to make this fully filled, but we 00:19:58.240 --> 00:20:04.400 do have four sets of double, which is like 00:20:01.559 --> 00:20:08.320 honestly barely enough for one radiator, but it'll be better than nothing. I can 00:20:06.400 --> 00:20:13.120 definitely feel the air coming through is a touch warm when it comes through 00:20:10.720 --> 00:20:18.160 these cuz it's really pulling that air through there super 00:20:15.080 --> 00:20:20.720 fast, but it does work. All right, 00:20:18.160 --> 00:20:25.360 brother. Isn't this the worst thing ever? Come, come stand there. I Jake, I 00:20:23.520 --> 00:20:29.840 can feel it. Stand right there. I need you to endure what I've been enduring. 00:20:27.760 --> 00:20:34.640 Oh, you having fun? Yeah, it's really hot. Stay there. Sorry. 00:20:32.960 --> 00:20:38.120 Why would you put your armpits like that? Get out of 00:20:35.960 --> 00:20:45.280 here. Oh, I'm sorry. Back there. No. 00:20:42.679 --> 00:20:51.840 Wow. The door handle even works. Isn't that crazy? Wow. Like what? No way. 00:20:49.919 --> 00:20:56.559 That's actually almost unbelievable. whole line. Well, how cool is the 00:20:54.400 --> 00:21:01.120 Really? The water's not even that cold, but 00:20:58.240 --> 00:21:05.480 Dude, it really takes the like the edge off it. I didn't just shut this. I 00:21:03.280 --> 00:21:13.120 forgot that I left it shut for like the last 45 minutes or something. 00:21:09.640 --> 00:21:15.919 Wow. That is night and day. And it 00:21:13.120 --> 00:21:20.159 doesn't leak. We had zero leaks. Zero leaks now. No, there was no leaks. Oh. 00:21:18.240 --> 00:21:24.799 Oh. Other than the leak that you caused earlier, the one that I had to fix, this 00:21:23.039 --> 00:21:30.960 is being That is not true. This is being held together with like a millimeter of 00:21:27.520 --> 00:21:34.559 solder. I'm actually genuinely like I'm 00:21:30.960 --> 00:21:37.120 shocked at how well this works. 00:21:34.559 --> 00:21:42.080 And the door even I mean it's jank, but it it does it does function. And look, 00:21:39.360 --> 00:21:46.559 you can see our swivels. They swivel. Oh This one doesn't really, but we 00:21:44.159 --> 00:21:52.559 we're not talking about that, right? Okay. Yeah, they swivel. They swivel. 00:21:49.280 --> 00:21:54.400 Swivel enough. Yeah. Oh, god. Close it. 00:21:52.559 --> 00:21:57.840 Yeah, it's really awful, actually. Look at the fans. Yeah. See, you can see 00:21:56.640 --> 00:22:03.120 they're really pulling the heat through there. They're really drawing more of that hot air out of there. I think we're 00:22:01.039 --> 00:22:07.360 going to need more active assistance for it. Oh, wow. 00:22:05.760 --> 00:22:11.720 The door is like, if you find the right spot, it's like 30 35. Yeah. Which is 00:22:09.679 --> 00:22:15.120 about what we'd expect. About room temperature, you know. Plus, we can't 00:22:13.760 --> 00:22:22.400 dissipate everything out into the warehouse. And then the back of the servers are anywhere from 45 to 55 to 00:22:20.240 --> 00:22:26.240 50. Are you going to acknowledge what you just did? So, as you found out, we 00:22:24.480 --> 00:22:32.159 need a bigger power supply. Yeah. The little 24 watt one for that Noctua hub 00:22:29.200 --> 00:22:36.320 only powers three of those fans safely. Yeah. Um and then I remembered we had 00:22:34.000 --> 00:22:43.280 this laying around. This is an HDLEX gallium nitride PC power supply. This is 00:22:39.679 --> 00:22:44.880 500 watts with no cooling. Or maybe 00:22:43.280 --> 00:22:49.679 there is a little fan there. That looks like a little fan. It might have a fan. 00:22:46.880 --> 00:22:53.120 It's small, but it's Yeah, it's pretty impressive to fit 500 watts in this 00:22:51.440 --> 00:22:57.600 package. And you can daisy chain them. The main thing is that it's small and it'll be easy to mount to the side of 00:22:55.600 --> 00:23:01.360 this thing. And then took a generic power supply cable. We had use some WGO 00:22:59.440 --> 00:23:05.360 nuts. And then we have a Molex, which should be good enough to run that many 00:23:03.600 --> 00:23:07.840 fans. I think Molex is like 100 watts it can do, right? We'll have a link in the 00:23:06.799 --> 00:23:12.320 description for where you can get some WGO nuts and at least some of the other 00:23:10.080 --> 00:23:16.679 stuff we showed in this video. No professional company server room would 00:23:14.480 --> 00:23:22.320 ever look like this. How boring. Now, what we're going 00:23:20.000 --> 00:23:26.240 to do is leave it for about 20 minutes. We've got our AC coming in. It's 00:23:24.159 --> 00:23:31.120 apparently fixed. Comes into the front of the rack. The air comes out freaking 00:23:28.880 --> 00:23:34.799 hot. We pull as much of the heat away from it as we can. Dump it out into the 00:23:33.039 --> 00:23:39.840 warehouse, which this time of year we're paying to heat anyway. And then we see 00:23:37.360 --> 00:23:44.559 where we land. We had a few more issues with the air conditioning, which is, but 00:23:42.720 --> 00:23:48.960 it seems to be sorted now. And we've had it running with the door shut since 00:23:46.400 --> 00:23:52.559 noon, and it's now 400 p.m. And I can see based on the chart that everything 00:23:50.400 --> 00:23:56.240 does look to be very heat soaked. If we look at our EcoB thermostat, which is 00:23:54.799 --> 00:24:02.559 what's controlling the air conditioning specifically, we can see it's pretty 00:23:58.240 --> 00:24:05.440 much settled off from like 29.9 to 30 00:24:02.559 --> 00:24:09.840 12° C, which is technically speaking a degree or two lower than we were at 00:24:06.960 --> 00:24:15.360 before, which is uh great. I was just happy that we had all of the space back, 00:24:13.039 --> 00:24:18.799 but um to also get a bit of a performance improvement is awesome. And 00:24:17.120 --> 00:24:24.240 especially once we put the cooling tower we took out of the server room up on the mezzanine. I'm hoping that we can get 00:24:21.840 --> 00:24:31.279 even better results. Let's go take a look with the thermal camera. Wow, it is 00:24:27.880 --> 00:24:33.840 definitely still warm on this side. Look 00:24:31.279 --> 00:24:42.159 at that. You can see the gradient on the rack. Like the front of the rack 00:24:37.080 --> 00:24:44.880 38°, back of the rack 50°. Woo! She's 00:24:42.159 --> 00:24:48.000 cooking. I added a few more fans cuz it seemed like a good idea. And to be 00:24:46.480 --> 00:24:53.039 honest, I'm probably going to add a few more even. But looking at the 00:24:51.159 --> 00:24:58.080 radiator. Oh, you know what I want to see is the hoses. So that is our input. 00:24:56.080 --> 00:25:05.600 It looks like the outer temperature of it at least is 00:24:59.559 --> 00:25:07.000 around 34° and then our output 36°. Not 00:25:05.600 --> 00:25:10.760 a great way to measure the water temperature, but it does give us some 00:25:09.200 --> 00:25:17.279 idea. That was interesting. 34.4 00:25:13.080 --> 00:25:18.120 four and 36. It's interesting cuz you 00:25:17.279 --> 00:25:24.240 can feel I can feel the heat coming through 00:25:22.080 --> 00:25:28.400 with the fans, but then the air that comes through in between where the fans 00:25:25.919 --> 00:25:33.480 are is cool. Let's try to crack this open a little bit on the back of the 00:25:30.799 --> 00:25:39.520 machines. It's still around 50°. Anyways, it seems like the 00:25:36.640 --> 00:25:43.760 servers inside, despite this being a bit warmer than it was before, aren't doing 00:25:41.600 --> 00:25:47.640 too bad. Felt a little crazy when it was just like an idea, but now to actually 00:25:46.000 --> 00:25:52.240 see it working in practice, I'm stoked. Just like you 00:25:50.559 --> 00:25:56.559 should be stoked about our sponsor, Nexigo. Their Tri Vision Ultra 4K 00:25:54.559 --> 00:26:02.080 projector lets you lose yourself in a true cinematic experience.
