I I can't","speaker":null,"is_sponsor":0},{"start_s":398.639,"end_s":403.52,"text":"make it work over here.

I had a really stupid idea that I think is maybe","speaker":null,"is_sponsor":0},{"start_s":467.12,"end_s":472.88,"text":"actually not that stupid.

And look at","speaker":null,"is_sponsor":0},{"start_s":479.56,"end_s":484.639,"text":"that. A whopping I don't want to think","speaker":null,"is_sponsor":0},{"start_s":482.639,"end_s":489.0,"text":"about how much longer later.

This one not","speaker":null,"is_sponsor":0},{"start_s":491.759,"end_s":497.8,"text":"great, but I can at least force a fitting on there now, which means we can","speaker":null,"is_sponsor":0},{"start_s":496.8,"end_s":502.879,"text":"solder it.

It's all pumped","speaker":null,"is_sponsor":0},{"start_s":533.399,"end_s":539.2,"text":"up.

Looks like you guys","speaker":null,"is_sponsor":0},{"start_s":552.64,"end_s":557.519,"text":"already cut this out. Yeah, we tried to find the ones that were the least","speaker":null,"is_sponsor":0},{"start_s":555.839,"end_s":562.399,"text":"disgusting, and it seemed like the top ones were the least corroded. So, we","speaker":null,"is_sponsor":0},{"start_s":559.44,"end_s":566.16,"text":"destroyed two towers. Okay. Well, this looks great. But I do have a question.","speaker":null,"is_sponsor":0},{"start_s":564.48,"end_s":570.16,"text":"Is there a reason that we're salvaging these radiators rather than just using","speaker":null,"is_sponsor":0},{"start_s":568.8,"end_s":575.6,"text":"radiator doors?

At least it's","speaker":null,"is_sponsor":0},{"start_s":589.6,"end_s":596.36,"text":"more fun right now. We haven't got to the part where there's problems yet. And","speaker":null,"is_sponsor":0},{"start_s":593.92,"end_s":600.48,"text":"build a water door. I shall. At least in theory. Now I'm","speaker":null,"is_sponsor":0},{"start_s":598.959,"end_s":603.6,"text":"working on how we're going to lay this stuff out. The bottom and the middle are","speaker":null,"is_sponsor":0},{"start_s":602.24,"end_s":608.959,"text":"going to be very easy. We're just going to use these 3/4 NPT to 3/4 ID barbs. So","speaker":null,"is_sponsor":0},{"start_s":607.519,"end_s":612.08,"text":"they'll just twist on. The top connection on each radiator is a little","speaker":null,"is_sponsor":0},{"start_s":610.56,"end_s":616.56,"text":"bit more complicated because we need to connect it to the bottom one. So what","speaker":null,"is_sponsor":0},{"start_s":614.56,"end_s":623.12,"text":"I'm thinking I'm going to do is use one of these T fittings and then a right","speaker":null,"is_sponsor":0},{"start_s":619.12,"end_s":625.12,"text":"angle.

Our nickname for this wild nine server cluster with a combined two pabytes of Kiosia Gen 4 NVD storage has been causing some serious problems in our server room. Thanks to the 7 to 8,000 watts of heat it kicks out, it got so freaking hot in here that we needed to cool our lab server room. And even with the setup we've got now, it's still a little toastier than we'd like it here. Of course, it is a lot better than it used to be, thanks to our proof of concept heat exchanger setup that we cobbled together with a pair of APC data center cooling towers that we found behind a local data center. In a nutshell, this one grabs heat that gets thrown out directly out the back of the million-doll PC. Then it pumps that hot water up here where a second cooling tower yates that heat out into the warehouse which we would have to pay to heat anyway. Hey, Alex. The issue is that our proof of concept here kind of introduced some new problems. For one thing, while this tower does an ungodly amount of cooling, it also takes up an ungodly amount of space. It's designed to go in between racks of servers to chill the air, not behind them, which is the other problem. We don't have separate hot and cold aisles in this closet we call a server room. So, our cardboard duct here is how we get the hot air to the radiators inside our cooling tower. At best, this is a phenomenal waste of space and at worst kind of a fire hazard. Which raises the question, why all of this when we could just attach our radiators directly to the back of the rack? It would not only get us our space back, but it would probably work though. Oh my god, it's leaking water. Oh Jesus. We've got all the radiators we could ever need. What could possibly go wrong? A lot. Just like a lot of segue to our sponsor, Nexigo. Their Tri Vision Ultra is a 4K projector designed to be easily set up anywhere thanks to its autoscreen detection and convenient grab handle. Pick one up today using our link in the description. With that said, the current setup is kind of working. The filter is filtering. The purge for the filter is uh please don't open purgeable. Oh my god. And our auto topup with that uh toilet float in it. Totally works. It doesn't leak either actually, which is great. So, we don't need to change anything major here. But what we are doing today is dealing with this pump. It is weak sauce and is made of cast iron, which not ideal in a mixed metal loop, even if you are using corrosion inhibitors, which we aren't yet. Yet. Yet. Are we adding that today? No. Oh, god. Jake. Well, once we prove this setup works, then we might. Um, wait. What are you doing? I'm undoing this so we can put the new pump in. Have you considered maybe we should like disconnect it down there so it doesn't just spill water all over everything? Sure. All right. Oh, Jesus. Well, what did you think was going to happen? Water, J. You still continue to do the thing I said you shouldn't do. That's what I I thought maybe you would think about what I said instead of just continuing to do the thing you shouldn't have done. Okay. There's only an electrical box right down there that it pours directly into. Oh, not just an electrical box. The electrical box. The whole electrical room for the building. Yeah, it's down there. Um, now the flanges I originally ordered for this project finally showed up. Uh, you see they have a valve on there so you can isolate the pump. Oh, that's downright useful. That would have been great at a couple minutes ago. Yeah, we could swap it or we could just stick that one right back where the old one was. Yeah. Okay, 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 stainless steel from cast iron, but this thing is about a sixth of a horsepower. So, to put that in context, it'll do about 25 gallons per minute with 10 feet of head pressure, which is about double what you'd get out of a typical garden hose. Oh, yeah. There she goes. Now, I was joking in the intro, we haven't actually cut anything in these towers. And then Justin just informed me that we can't cut anything in the towers yet without getting the door off, which is conveniently locked. This is looking very successful. 10 out of 10. Should we just use a drill? How does this work? Oh, what is this? There's a button. Oh my god, there's a button. We are just actually so stupid. We're so Yeah, we're so stupid. Oh my god, they're torques. Why are they Torx? Fortunately for us, you can get extra screwdriver bit sets like this torque set for the LTP store screwdriver. Nice. So, these radiators are a little weird. There's three connections. I'm assuming it's like this is the inlet and then we have two outlets. And I'm like, okay, let's let's measure these pipes and I can go buy some of the fittings ahead of time. This is like 3/4 of an inch on the outside. This is like 7/8. And this is like 3/4. So I probably need 7/8 and 3/4 copper fittings, right? Wrong. The copper fittings I need are 5/8 and 3/4. Why? I don't know. Well, it turns out 5/8 copper pipe is not a type of pipe you use for plumbing. So the plumbing guy was like, 5/8? Why do you need 5/8? We don't we don't sell that. You have to go to an HVAC store. That's a refrigeration size. Luckily, I found a plumbing HVAC store that sold both and they happen to have the fittings that I need. These are 5/8. And if I look if I if I measure them with the fancy calipers here, 0.76, and 0.7 675, 772, depending on where you measure. Nothing a little solder can't fill. Starting with the inlet. Now, if we look at the fitting here, we've got almost the amount we need. I I can't make it work over here. So, we're going to leave this solder joint in here and 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 section. So, to try that, I'm going to heat it up and then Justin's going to try to bend it. Like, we don't need much. It's just elongating it. Like, see, it's just like squished. Oh, no. Probably just made it worse. Probably. This is definitely This is definitely not better. It is actually worse. Why don't we just try cutting that off and just see how it looks? Sure. Sure. You want to grab a sawzaw? Yeah. Hey. Yeah. I'm sure it'll fit right on there. This is not going to leak. There's no way this is going to leak. Wow. That is That's uh at her there, bud. For real, dude. Look how mint this is. I don't want to keep doing this. This is making it worse. It's very important to make sure you clean your definitely not destroyed copper pipe before you solder as otherwise the solder won't stick. I had a really stupid idea that I think is maybe actually not that stupid. I was trying to find something that would fit like the exact or close to radius. And look at that. A whopping I don't want to think about how much longer later. We've hammered a socket in which mostly reformed this one. The other radiator looks almost spot on. This one not great, but I can at least force a fitting on there now, which means we can solder it. Will it leak? Probably. But that's a problem for later, Jake. I'm going to put some flux on here, which will clean the part up when it's heated up. Both of our radiators now have fittings soldered onto them and hopefully don't leak. But that's not something I want to just gamble on. So, I wanted to find a way that we could leak test it. And I've got this little leak tester, which is literally just an air pump with a gauge. So, you hook it up, pump it up, and that gauge will show your pressure. We spray some Windex on there. It's all pumped up. But, if we look, our solder joint looks clean. Ignore all the bubbles from the plastic. That's unrelated. No bubbles. They're not pretty, but they don't leak. And that's good enough for me. Looks like you guys already cut this out. Yeah, we tried to find the ones that were the least disgusting, and it seemed like the top ones were the least corroded. So, we destroyed two towers. Okay. Well, this looks great. But I do have a question. Is there a reason that we're salvaging these radiators rather than just using radiator doors? It's like those are totally a thing, brother. I tried. They either just like stopped responding to my messages, didn't respond at all in the first place, or were like, \"It will be $60,000.\" Oh. And then I remembered we had this. And this is more fun. Cool. Yeah. Time to build a water door. At least it's more fun right now. We haven't got to the part where there's problems yet. And build a water door. I shall. At least in theory. Now I'm working on how we're going to lay this stuff out. The bottom and the middle are going to be very easy. We're just going to use these 3/4 NPT to 3/4 ID barbs. So they'll just twist on. The top connection on each radiator is a little bit more complicated because we need to connect it to the bottom one. So what I'm thinking I'm going to do is use one of these T fittings and then a right angle. We'll use that kind of like this. And then this guy will go kind of like that. So, we can have this tube come off and connect to there. And this one's already connected. And then we just have one feed in for each of our radiators. It just looks like a normal barb, but spin it. Yeah. Oh. Ooh. It's a swivel barb. It's exactly what I needed. And it was $11. Really? Yeah. That's not bad. Green line hose and fitting, baby. They have everything. Oh my god. And I just ruined them all. That's my job. Yeah. Okay. How does this help us again? Because the door has to move and we can't just rely on like a rubber hose bending back and forth. We'd have to leave a ton of extra to make that work. Got it. No, that's got to go down this way. Okay. What if that went here and I go in there and then it went going to hang. I mean, I guess we could do it like down like that maybe. Oh, yeah. That's it's pretty I don't have a nipple either, so I don't know if we can do that. Yeah. Don't. I swear to God. There are large tools here and he is one of them. No, we don't need this. But that's doing the same thing. Yeah, but it's in a dumb spot, though. Why is it 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 easier. It doesn't seem easier. And then this Why do we need to go to the bottom of this rad to the bottom of the other rad? Because because let's say the other one has already been done like Oh, okay. That already has a T on it. Yeah. Well, wait. Why are you even proposing a new solution when you already solved it already? I'm trying to tell you this. But you don't listen. 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 manage that? Well, I didn't need a nipple because I had this excellent plan that you've now changed. So, we're going to have our two hoses that come off of the tubing that's in the building, like the PEX tubing, go to here and here. This will be our outlet. This is our inlet. From our inlet, it gets split only once, which is nice. It'll go right to this input, and then a tube will come down over to here. And then the other side, the outlet, it gets really freaking awful fast. We'll have our input splits right here into this guy. And then it comes down into here. Splits again into this guy in here. Plugs into here. Splits again down to there. When you're doing something like this that's a permanent installation. There's a much better type of hose clamp that are constant pressure ones where it's just like a giant spring. These ones are fine, but they can loosen up over time, especially in an environment where there's like a lot of vibration. While Linus works on getting the fittings for our leak testing thing, I am screwing the radiators in. They luckily have a nice like L channel on one side which we can just screw directly through the door to hold the one side and then on the other side we're going to use these mounts that Justin 3D printed along with T-nuts that are really meant for 8020 but have a really nice flat face which should hold nicely against the grid and that'll hold the other side. This is a big moment. I suspect there will be at least one place that is leaking. You know what? I'll take that bet. I No leaks. Oh, what? I say no leaks for lunch. Uh, I don't know that I would bet anything on it, but I say no leaks. Really? Yeah, dude. There's no way. Do you remember last time doing that the the first setup? Oh my god. I do. Oh, I found a leak. Shoot. Exactly on where the Teflon tape got all crumpled like I was just saying. Dang it, Jake. We're going to have to do a lot of removal of things to get at that. Yeah, that's the worst possible place it could have leaked is right there. That sucks. But hey, at least we're doing this now and not when it's full of water next to a bunch of servers. Oh, hold on. What's this? I think we got another one. Same thing. No, no, no. We got another one. Upon closer inspection, it appears that when we bent this thing, we made like a little hairline crack in that very bottom tube, which sucks. I don't really want to redo all of this at this exact moment. So, I'm going to try and just put some solder on it and hope that that holds. I already like scotchbrighted the hell out of it, so it's clean. I'm going to put some flux on. And now we get to find out if this is going to work. There was like the tiniest little bubble on this fitting. So, I tightened it a little bit more because it wasn't quite as in as some of the other ones. And I think we're good. It's been like 5 minutes already and this dial has not moved at all. And I don't I like Windexed all the fittings again and I don't see any leaks. We might be okay. Fast forward a little bit and I've mounted the plastic side bracket thingies on and we now have a water door which I've been told is just a rack door with radiators on it. Surprise. Look at that. It holds. What a monster. Although with no water in it. Now you might be wondering what are we going to do about all of this extra air flow? cuz ideally we want any of the air from the servers to go through the radiators. For now, we're just going to use tape, but in the future, I'm thinking we could 3D print a little like angled piece kind of like there and kind of like there to duct the air into the radiator kind of like a velocity stack would. Pretty mint, right? Yeah. You going to cut this off? It's blocking air flow. I You mean you complain about my tape drop, but then you don't cut that off? Well, this is blocking air flow. This is sentimental. Oh yeah. Hi. Oh, okay. I'm really glad I put valves on that. If all of this hasn't made a ton of sense to you yet, hopefully it makes a little more sense. Now, we have our rack here. This is the back. So, back here, all the servers, they're blowing a bunch of air and it's hot. So, we're going to put our radiator door here. And hopefully the idea is the water going through it at like 20ish°ish will catch the heat. And then once the air goes through it, it should come out colder. And instead of using that giant tower over here with all the cardboard and stuff, the whole unit only takes up about this much space. So we save space. It'll probably work a bit better because it's closer. And um it's just freaking cool. Hey. Holy dude. Oh, okay. So, here's a really The air comes through. It is maybe not strong enough to do this on its own. We might need to add fans. This is a bit of a crazy concoction, but we've got a 1-in PEX fitting, which is the same size as this stuff here. It's PEX plastic tubing. And then it gets reduced down to 3/4, which is the same size as this. And then we've got a swivel fitting. Kind of one leg there, and then one leg there. And then we'll run our rubber hose from here to here and hopefully it just works. Previously we were using fittings called shark bites which are kind of like a easy solution where they have like O-rings and it's like a self you just quick disconnect push it in there but I'm switching them up to crimps which use a metal ring around the pecs and then you crimp them on with a tool and it compresses the plastic together. In theory a much more secure connection. We're going to have to find out. A little bit top, but nothing crazy. And then open. Ah, it's swiveling a little. Let's um add a little bit of water. I guess Jamie turned on the water. So, we're filling up. So, this is just room temperature water, right? We're cooling it with the air in the warehouse, which is around 20°. It's so weird to stand behind this and the air coming off it now to be cool. It actually feels like colder than the room in here. Honestly, that's weird. That's so weird. And then you open it up and you're like, \"Oh god, it's so hot. I suspect we're like cooking inside there.\" But then again, the servers are taking in fresh air. I don't know. Maybe it's fine. Got John here, our test technician extraordinaire, god of numbers. That's awful, right? Yeah. That's like like putrid, right? You actually like kind of feel it's almost a little cold coming off of it. Like shockingly working. You've seen a little bit of this, right? Yeah, a little bit. How well do you think this is going to work? Uh, you know how hot it was in there with the other cooling tower in there, right? You can feel it already kind of. Yeah. Yeah. Okay, come on. So, let's let's take a sample. Stand behind the thing. I know it's weird. There's so much space in here. Awful, right? Like actually horrible. Stand behind the thing. Like, it's cool. Oh my god. What? What did you do? I don't know. Yeah, I know, right? Oh, yeah. Yeah, we made our little double fan stackeroonis. These are Noctu industrial 30,000 RPM fans. They're called industrial because they're meant for industrial. This feels industrial, right? I think this is a reasonable use of these. Um, I don't have enough of them to make this fully filled, but we do have four sets of double, which is like honestly barely enough for one radiator, but it'll be better than nothing. I can definitely feel the air coming through is a touch warm when it comes through these cuz it's really pulling that air through there super fast, but it does work. All right, brother. Isn't this the worst thing ever? Come, come stand there. I Jake, I can feel it. Stand right there. I need you to endure what I've been enduring. Oh, you having fun? Yeah, it's really hot. Stay there. Sorry. Why would you put your armpits like that? Get out of here. Oh, I'm sorry. Back there. No. Wow. The door handle even works. Isn't that crazy? Wow. Like what? No way. That's actually almost unbelievable. whole line. Well, how cool is the Really? The water's not even that cold, but Dude, it really takes the like the edge off it. I didn't just shut this. I forgot that I left it shut for like the last 45 minutes or something. Wow. That is night and day. And it doesn't leak. We had zero leaks. Zero leaks now. No, there was no leaks. Oh. Oh. Other than the leak that you caused earlier, the one that I had to fix, this is being That is not true. This is being held together with like a millimeter of solder. I'm actually genuinely like I'm shocked at how well this works. And the door even I mean it's jank, but it it does it does function. And look, you can see our swivels. They swivel. Oh This one doesn't really, but we we're not talking about that, right? Okay. Yeah, they swivel. They swivel. Swivel enough. Yeah. Oh, god. Close it. Yeah, it's really awful, actually. Look at the fans. Yeah. See, you can see they're really pulling the heat through there. They're really drawing more of that hot air out of there. I think we're going to need more active assistance for it. Oh, wow. The door is like, if you find the right spot, it's like 30 35. Yeah. Which is about what we'd expect. About room temperature, you know. Plus, we can't dissipate everything out into the warehouse. And then the back of the servers are anywhere from 45 to 55 to 50. Are you going to acknowledge what you just did? So, as you found out, we need a bigger power supply. Yeah. The little 24 watt one for that Noctua hub only powers three of those fans safely. Yeah. Um and then I remembered we had this laying around. This is an HDLEX gallium nitride PC power supply. This is 500 watts with no cooling. Or maybe there is a little fan there. That looks like a little fan. It might have a fan. It's small, but it's Yeah, it's pretty impressive to fit 500 watts in this 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 this thing. And then took a generic power supply cable. We had use some WGO nuts. And then we have a Molex, which should be good enough to run that many fans. I think Molex is like 100 watts it can do, right? We'll have a link in the description for where you can get some WGO nuts and at least some of the other stuff we showed in this video. No professional company server room would ever look like this. How boring. Now, what we're going to do is leave it for about 20 minutes. We've got our AC coming in. It's apparently fixed. Comes into the front of the rack. The air comes out freaking hot. We pull as much of the heat away from it as we can. Dump it out into the warehouse, which this time of year we're paying to heat anyway. And then we see where we land. We had a few more issues with the air conditioning, which is, but it seems to be sorted now. And we've had it running with the door shut since noon, and it's now 400 p.m. And I can see based on the chart that everything does look to be very heat soaked. If we look at our EcoB thermostat, which is what's controlling the air conditioning specifically, we can see it's pretty much settled off from like 29.9 to 30 12° C, which is technically speaking a degree or two lower than we were at before, which is uh great. I was just happy that we had all of the space back, but um to also get a bit of a performance improvement is awesome. And 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 even better results. Let's go take a look with the thermal camera. Wow, it is definitely still warm on this side. Look at that. You can see the gradient on the rack. Like the front of the rack 38°, back of the rack 50°. Woo! She's cooking. I added a few more fans cuz it seemed like a good idea. And to be honest, I'm probably going to add a few more even. But looking at the radiator. Oh, you know what I want to see is the hoses. So that is our input. It looks like the outer temperature of it at least is around 34° and then our output 36°. Not a great way to measure the water temperature, but it does give us some idea. That was interesting. 34.4 four and 36. It's interesting cuz you can feel I can feel the heat coming through with the fans, but then the air that comes through in between where the fans are is cool. Let's try to crack this open a little bit on the back of the machines. It's still around 50°. Anyways, it seems like the servers inside, despite this being a bit warmer than it was before, aren't doing too bad. Felt a little crazy when it was just like an idea, but now to actually see it working in practice, I'm stoked. Just like you should be stoked about our sponsor, Nexigo.
