WEBVTT 00:00:00.000 --> 00:00:04.500 Usually it's my kids who break stuff, and I'm the one who gets to fix it. 00:00:04.500 --> 00:00:13.200 But when corrosion in my DIY pool water cooling setup caused a catastrophic leak on his gaming PC, 00:00:13.200 --> 00:00:16.300 it seemed like a perfect opportunity to flip the script. 00:00:16.300 --> 00:00:21.200 And sure, it's my fault it broke, but what good are kids if you can't put them to work? 00:00:21.200 --> 00:00:24.800 And besides, what a great opportunity for some learning. 00:00:24.800 --> 00:00:28.900 Yay, learning. You can learn the name of today's sponsor. 00:00:29.000 --> 00:00:32.900 Just because you have a spill on your computer doesn't necessarily mean that it's dead. 00:00:32.900 --> 00:00:38.300 If you can unplug it, clean it, dry it off, and fire it back up, it might work, 00:00:38.300 --> 00:00:41.400 just like the PC that we intentionally spilled coke on. 00:00:41.400 --> 00:00:48.700 But that's not what happened here. This system sat for hours in a puddle of water and its own corroded gunk. 00:00:48.700 --> 00:00:54.500 It should be dead, but somehow miraculously it survived, so then no problem. 00:00:54.500 --> 00:00:58.800 All I've got to do is have my son put his water cooling back in, right? 00:00:58.900 --> 00:01:02.700 Wrong. Because if we do that, it's probably going to corrode again. 00:01:02.700 --> 00:01:10.300 So we've got to figure out the root cause. The best theory we have is that this was caused by a ground loop between the pump and the computers, 00:01:10.300 --> 00:01:15.400 which causes a slight voltage differential which can drastically accelerate corrosion. 00:01:15.400 --> 00:01:19.300 Jake is actually working right now on the video that maybe you guys have seen, 00:01:19.300 --> 00:01:23.600 where we added an isolation transformer to the pumps and grounded the rack, which means, 00:01:23.700 --> 00:01:29.100 Hey, come on, boy. It's time to learn how to clean a really crusty water block. 00:01:29.100 --> 00:01:34.800 What am I ever going to do this again? Hopefully never, if Jake does all of this right. 00:01:34.800 --> 00:01:39.700 Probably soon. But if it happens again, we're going to be in relatively okay shape 00:01:39.700 --> 00:01:44.700 because one of the other things we're going to be installing in the boy's computer is a leak sensor. 00:01:44.700 --> 00:01:49.000 Well, what are you waiting for? Let's go. Luckily, the only things that got eaten away were the fittings. 00:01:49.100 --> 00:01:55.500 So all we've got to do now is remove all of the gunk that was deposited from the fittings onto these blocks. 00:01:55.500 --> 00:01:59.600 Now, the bad news for you is I accidentally left my brasset at the office. 00:01:59.600 --> 00:02:03.400 So you get to try this Mother's Magan Aluminum Polish, 00:02:03.400 --> 00:02:08.400 which I don't know if it's going to work, or Goof Off, which I really think is not going to work. 00:02:08.400 --> 00:02:11.900 Here's a toothbrush. You'll need water. 00:02:11.900 --> 00:02:16.100 Okay, that's not doing much. Let's try some Mag Polish. 00:02:16.100 --> 00:02:19.800 That's probably not what that's supposed to look like. Oh, it smells so bad. 00:02:22.300 --> 00:02:26.500 Okay, let's see. Very similar to how it did before. 00:02:26.500 --> 00:02:32.300 It really does, doesn't it? I wonder if pick action is a better bet. 00:02:32.300 --> 00:02:39.600 That does actually seem to be a lot better. Do I really want to get a dental pick into all these little bins? 00:02:39.600 --> 00:02:43.100 Well, you're not doing it. Oh, yeah. 00:02:43.100 --> 00:02:49.300 I'll go get you a dental pick. I changed my mind. While I thought I had dental picks, it turns out I actually don't. 00:02:49.300 --> 00:02:53.200 But what I do have is a lot of X-Acto knife blades. 00:02:53.200 --> 00:02:57.200 Oh, wow, yeah, this comes off really good. Don't cut toward your finger like that, 00:02:57.200 --> 00:03:00.300 because if you put that into your thumb, we will have to go to the ER room. 00:03:00.300 --> 00:03:05.200 And you'll need a tetanus shot like me. I got attacked by a cat. 00:03:05.200 --> 00:03:08.600 So fun. I wouldn't rather be doing anything else. 00:03:08.600 --> 00:03:12.600 I'll tell you what, boy. I'm nothing if not fair. You clean that piece. 00:03:12.600 --> 00:03:16.500 I'll clean these three pieces. OK? 00:03:16.500 --> 00:03:22.500 Good deal? Maybe. What I didn't tell my son is there is another way. 00:03:22.500 --> 00:03:25.700 I brought an ultrasonic cleaner home. 00:03:25.700 --> 00:03:29.100 I could clean so much water block with this bad boy. 00:03:29.100 --> 00:03:34.500 Got some general purpose ultrasonic cleaner, lemon scented. 00:03:34.500 --> 00:03:38.700 There they go. I hope I have enough of this. 00:03:38.700 --> 00:03:44.400 I only have the one jug. Extra strength formula. 00:03:44.400 --> 00:03:49.100 This product is a concentrate. One part product with 10 parts water. 00:03:49.100 --> 00:03:54.000 I have created some work for myself. 00:03:54.000 --> 00:03:57.400 I don't even know what color the back is supposed to be. 00:03:57.400 --> 00:04:00.500 Just salvage some of that back. 00:04:00.500 --> 00:04:04.300 Oh, yeah, buddy. 00:04:04.300 --> 00:04:10.100 And here's some water. 00:04:10.100 --> 00:04:15.600 Why don't we kick things off with the top of the CPU block? All of this stuff was pretty easy to get the gunk out of. 00:04:15.600 --> 00:04:20.300 I actually did that before. But what's hard to get at is these threads in here. 00:04:20.300 --> 00:04:25.400 This should help with that in a big way. Let's heat it up. 00:04:25.400 --> 00:04:29.900 Right, I forgot what a horrible noise it makes. OK, let's throw this bad boy in there. 00:04:29.900 --> 00:04:34.400 Dude, ultrasonic cleaners are freaking awesome. 00:04:34.400 --> 00:04:39.300 Can I use the ultrasonic cleaner? 00:04:39.300 --> 00:04:43.700 Sure. When were you going to tell me about the ultrasonic cleaner? 00:04:43.700 --> 00:04:49.800 It wasn't. These are great. They use ultrasonic vibrations to create these little scrubby 00:04:49.800 --> 00:04:54.000 micro bubbles that will remove any debris and crud from the surface 00:04:54.000 --> 00:04:58.400 of like a water block or a piece of jewelry or whatever the case may be. 00:04:58.400 --> 00:05:02.600 Wow. Not that we necessarily need it. You made really good progress. 00:05:02.600 --> 00:05:06.000 Yay. The boy can do work when he wants to. Check this out. 00:05:07.000 --> 00:05:10.500 Oh my God. Yeah, sorry. That is awful. Yeah, I know. 00:05:10.500 --> 00:05:14.800 Whoa, look at it rip off this corrosion on this bad boy. 00:05:14.800 --> 00:05:18.300 You can actually see big flakes coming off this guy. Check that out. 00:05:18.300 --> 00:05:22.700 Now it's time to pull the system. So go around to the back, get it turned off and unplugged. 00:05:22.700 --> 00:05:29.300 We're going to be doing two things. We're going to unjerry rig it. So you can see I threw a replacement air-cooled graphics card in here. 00:05:29.300 --> 00:05:32.400 That's going to have to go. And we're going to add a leak sensor. 00:05:32.400 --> 00:05:36.600 Now Jake is working on the parts that will do the actual monitoring and handle 00:05:36.600 --> 00:05:40.500 automations to turn the systems off in the event of a leak. 00:05:40.500 --> 00:05:44.000 Meanwhile, we will be installing this leak sensor. 00:05:44.000 --> 00:05:47.300 This appears to be too. Are we expecting there to be two leak sensors? 00:05:47.300 --> 00:05:51.000 They just came in packs of two. How's that supposed to sense when there's a leak? 00:05:51.000 --> 00:05:57.700 These are powered by five volt DC power. And basically what happens is if the two probes come into contact with water 00:05:57.700 --> 00:06:00.800 at the same time, the water is going to act as a wire, 00:06:00.900 --> 00:06:04.300 which is going to connect our powered probe to our sense probe. 00:06:04.300 --> 00:06:08.100 I mean, here's the thing, like realistically the water is going to pour out 00:06:08.100 --> 00:06:14.300 and then probably just dump down to the next server. So these sensors inside the computers, they might not do that much. 00:06:14.300 --> 00:06:18.400 So we're also going to add sensors to the floor and that'll probably be what saves us. 00:06:18.400 --> 00:06:22.800 Hey, we just got new cats. Do you want to come meet the cats? Come on, let's come meet the cats. 00:06:22.800 --> 00:06:27.900 They have fleas, so they have to hang out in here for a few more weeks until they're old enough for a flea treatment. 00:06:28.000 --> 00:06:33.100 And then that might actually be a good thing anyway because it'll give the other cats some time to acclimate to the idea 00:06:33.100 --> 00:06:36.100 that something doesn't smell right. Anyway, here they are. 00:06:39.800 --> 00:06:43.900 This might end up being a side adventure. LMG.GG slash Floatplane. 00:06:43.900 --> 00:06:46.300 Now that the new cat adventure is over, let's get some stuff mounted. 00:06:48.100 --> 00:06:52.900 Nice. Okay, now we got to strip it. Wouldn't something like this have a strip? 00:06:52.900 --> 00:06:57.800 It does. Then use this. Yeah, but it only works on this part. 00:06:57.800 --> 00:07:03.200 So then you figure out what gauge your wire is. You can look it up or you can just not bother. 00:07:03.200 --> 00:07:07.000 Okay. And then squeeze as hard as I can. Squeeze as hard as you can. 00:07:09.400 --> 00:07:10.800 Ow, it hurts my hands. 00:07:12.800 --> 00:07:17.200 Maybe squeeze harder than you can. Next time. It hurts. 00:07:19.000 --> 00:07:23.400 You know, you're going to get me made fun of on the Internet for having a boy with soft hands. 00:07:23.400 --> 00:07:28.900 I don't even like put product on or anything. My hands are just already soft. 00:07:28.900 --> 00:07:33.100 I'm shamed. Just tell them to not shame you. Yeah, they listen to me. 00:07:33.100 --> 00:07:35.400 Why do they watch your videos if they're not going to listen to you? 00:07:39.100 --> 00:07:40.500 That's a good question. 00:07:43.000 --> 00:07:44.900 That's great. That's not going to short out on anything. 00:07:46.200 --> 00:07:47.200 Ow, my hands. 00:07:50.600 --> 00:07:51.100 Shamed. 00:07:53.700 --> 00:07:55.800 Here's what we're going to do. We're going to slide a little thing in there. 00:07:56.900 --> 00:08:00.500 Like that. Then we're going to put this down on it. 00:08:00.500 --> 00:08:08.000 There we go. And we slide this out. And theoretically, we are exactly one paper width off the bottom. 00:08:08.000 --> 00:08:12.100 Now you got your screwdriver, right? Yeah. Okay. We need to remove this power supply. 00:08:12.100 --> 00:08:14.900 And we have a lot to do. I should go check on the ultrasonic. 00:08:16.800 --> 00:08:18.200 Oh, it stinks in here. 00:08:22.400 --> 00:08:25.000 Oh, you're going to put those in there? 00:08:25.800 --> 00:08:28.900 Yeah. Why not? You can just drain it out of here outside. 00:08:28.900 --> 00:08:32.200 Yeah, but I don't want to drain it. I want to maybe use it for some more stuff. 00:08:32.200 --> 00:08:37.200 Maybe I could clean your mom's jewelry. Would you ever even know how scuffed this was? 00:08:37.200 --> 00:08:39.700 Ow, ow, ow. Okay. 00:08:41.500 --> 00:08:47.300 Wow. That looks like freaking not quite new, but certainly a lot better. 00:08:47.300 --> 00:08:48.700 This is great. Check this out, Jake. 00:08:51.200 --> 00:08:55.300 That looks pretty gross still. What? No, that's copper. 00:08:55.300 --> 00:09:00.900 No, I meant all this. Can I see this? Yeah, Linus, she said, please, that's a magic word. 00:09:00.900 --> 00:09:05.300 No respect. What the? There's still some shmoo in here. 00:09:05.300 --> 00:09:10.800 So we might have to do another quick pass. While this is all still really soft and easy to get out, 00:09:10.800 --> 00:09:14.100 and then maybe we'll throw it in the ultrasonic cleaner again. 00:09:14.100 --> 00:09:18.400 Now is the perfect time to put our GPU back together. 00:09:18.400 --> 00:09:25.700 I did have to scrape some of this manually, but after the ultrasonic cleaner, man, does it ever come off easily? 00:09:25.700 --> 00:09:30.300 Since my GPU block is now clean, I'm ready to start putting my graphics card back together. 00:09:30.300 --> 00:09:33.700 And the good news is all of my thermal pads survived. 00:09:33.700 --> 00:09:36.900 What are thermal pads? Well, here, I can show you. 00:09:36.900 --> 00:09:40.400 There's stuff that makes heat, and we want to move that heat away from it 00:09:40.400 --> 00:09:46.400 so that it doesn't get too hot and die. But because they might be mounted a little bit higher 00:09:46.400 --> 00:09:50.400 or a little bit lower, we can't just put a piece of metal right against it 00:09:50.400 --> 00:09:53.400 because our piece of metal is going to be perfectly flat 00:09:53.400 --> 00:09:56.800 and it might not make contact with all of them. So a thermal pad, 00:09:56.800 --> 00:10:06.400 it's like a little pad that is thermally conductive so it can carry the heat through the pad and into our metal. 00:10:06.400 --> 00:10:11.000 You know how your computer runs games really fast? Without thermal pads, he no work. 00:10:11.000 --> 00:10:17.000 We got to make sure that this O-ring doesn't get crushed. If this gets crushed or it has anything in the way, 00:10:17.000 --> 00:10:18.200 pretty much game over. 00:10:21.400 --> 00:10:24.800 You guys, I asked for pipe cleaners. That's a pipe cleaner. 00:10:24.800 --> 00:10:28.800 I know, but this is an arts and crafts pipe cleaner. What pipe cleaners do I use? 00:10:28.800 --> 00:10:34.000 They try to clean the threads of the inside here and they bring me the fuzzy kind. 00:10:34.000 --> 00:10:38.400 I'll show you. This one? Yes, this. 00:10:38.400 --> 00:10:39.600 But a small one. 00:10:42.800 --> 00:10:44.000 Oh, that guy. 00:10:47.200 --> 00:10:52.000 Oh, no. Boy. 00:10:52.000 --> 00:10:56.800 Oh, he let the O-rings fall down. 00:10:56.800 --> 00:11:00.400 They're everywhere now. They were five when I put them in. 00:11:00.400 --> 00:11:04.800 Well, where's the fifth one? Oh, I think it went down the drain hole. 00:11:08.400 --> 00:11:11.400 Yes, it's there. Okay, good. Okay, well, no, don't put them there. 00:11:11.400 --> 00:11:15.100 Put them in here. Let's get this thing assembled. Let's go. 00:11:15.100 --> 00:11:19.100 I didn't take this one apart so I don't know where they go. How'd they go where they go? 00:11:19.200 --> 00:11:23.200 It occurs to me as I'm sitting here thermal pasting this GPU for reassembly 00:11:23.200 --> 00:11:28.700 that we don't actually know that it still works. While nothing else in the system failed, 00:11:28.700 --> 00:11:32.400 I don't think we ever actually tried booting it with the original GPUs. 00:11:32.400 --> 00:11:39.000 So now I would never recommend running 00:11:39.000 --> 00:11:42.700 a water-cooled GPU without any water in it. 00:11:42.700 --> 00:11:47.800 But hey, it's the do as I say, not as I do show, right? 00:11:47.800 --> 00:11:52.500 Let's see if this GPU works. If we get an output, I'm just gonna throw it in the system and call it good. 00:11:52.500 --> 00:11:55.900 Hey, look at that. We got an output. Let's go ahead and throw the system together. 00:11:55.900 --> 00:12:00.200 Oh, that's exciting. Might be a good time to get some of these tubes 00:12:00.200 --> 00:12:04.200 out of the way. How bad are these? Some of them don't even look dirty inside. 00:12:04.200 --> 00:12:09.300 Should I just replace all of them? I feel like I should just replace all of them. 00:12:09.300 --> 00:12:14.700 Actually, before I do that, I should test our new power supply bracket and make sure that it works. 00:12:14.700 --> 00:12:17.900 Oh, so perfect. Uh-oh. 00:12:17.900 --> 00:12:20.900 Did we leave enough clearance for the barrel jack? Oh, no. 00:12:20.900 --> 00:12:24.600 Oh, it's perfect. It's flawless. 00:12:24.600 --> 00:12:29.500 Look at that. Professional. So our five-volt leak sensor is gonna go in there like that 00:12:29.500 --> 00:12:34.600 and our fiber objects go in like that and the whole thing goes in here like that. 00:12:34.600 --> 00:12:41.100 Wait. No, there's not enough clearance for the barrel jack 00:12:41.100 --> 00:12:43.100 and the power supply. 00:12:47.900 --> 00:12:50.900 New solution. 00:12:50.900 --> 00:12:55.800 No nut to secure the DC barrel jack thing because, I mean, I don't know. 00:12:55.800 --> 00:12:59.000 Does it really need one? It's kind of in there, right? 00:12:59.000 --> 00:13:03.500 And it fits. Yay. 00:13:03.500 --> 00:13:09.800 You know what? This is kind of crazy, but because of the friction with the power supply, 00:13:09.800 --> 00:13:13.200 it's actually really secure in there, even without the nut. 00:13:13.200 --> 00:13:17.700 Like, I cannot move it. All right, we're back on track. Let's get the leak sensor back hooked up. 00:13:20.700 --> 00:13:25.200 There, I spared you guys a lot of the boring details, but she's completely re-plumbed 00:13:25.200 --> 00:13:28.800 and everything is ready to close up. I'm afraid I'm not optimistic enough 00:13:28.800 --> 00:13:32.800 to close up the top panel and slide it into its spot in the rack. 00:13:32.800 --> 00:13:36.500 So we're just gonna hook it on the top where it was before, 00:13:36.500 --> 00:13:40.000 hook up the water pipes at the back and see what happens. 00:13:40.000 --> 00:13:43.800 Boop. Boop. 00:13:43.800 --> 00:13:46.900 I don't have to power on the system in order to get liquid to flow through it. 00:13:46.900 --> 00:13:50.900 So this is a perfect time to see if anything's leaking. 00:13:50.900 --> 00:13:54.200 Everything seems fine. I mean, it should, you know, 00:13:54.200 --> 00:13:59.600 we removed the corroded fittings, but when you disassemble and reassemble water blocks, 00:13:59.600 --> 00:14:02.800 you can make mistakes, right? Dude, I'm stressed. 00:14:02.800 --> 00:14:06.400 I don't remember the last time I was this stressed to turn on a computer. 00:14:12.300 --> 00:14:17.600 Let's go see if she fires up. This is the monitor that's supposed to be lit up. 00:14:17.600 --> 00:14:20.600 Give her a sec. She's memory training. 00:14:20.600 --> 00:14:24.200 The memory's trained. Oh, thank God. Woo-hoo! 00:14:24.200 --> 00:14:28.600 Let's see how the temps are. All right, well, 00:14:28.600 --> 00:14:32.400 I should have repasted the CPU block. You didn't repaste the CPU block? 00:14:32.400 --> 00:14:35.700 Well, that was pasted on there. Oh my God. I'm gonna repaste it. 00:14:35.700 --> 00:14:38.900 I even brought PTM7950 from LTTstore.com for you. 00:14:38.900 --> 00:14:42.400 Oh, I didn't see it. In fairness to me, there was a solid chance 00:14:42.400 --> 00:14:46.000 that none of this was gonna work at all and any time we spent on it was a complete waste. 00:14:46.000 --> 00:14:49.000 So now that I know that the thing actually works, 00:14:49.000 --> 00:14:55.000 I can just pop this off, throw some more pasted on. Yeah, yeah, that's not enough pasted. 00:14:55.000 --> 00:14:58.000 Throw some more pasted on there and we'll call it a day. Ah! 00:14:58.000 --> 00:15:02.900 Thermal pad time. Hmm, temps are exactly the same. 00:15:02.900 --> 00:15:06.800 I bet the flow rate is lower from adding the filter. 00:15:06.800 --> 00:15:10.200 It's still going 10 liters per minute. That's a lot. 00:15:10.200 --> 00:15:13.700 Divided by seven systems. I think this might be a flow rate thing. 00:15:13.700 --> 00:15:16.700 Was it like that before? Hmm, I don't think so. 00:15:16.700 --> 00:15:19.700 I mean, I can also check one of the other systems. 00:15:19.700 --> 00:15:25.700 Yeah, this one's the same. Realistically, they aren't 3D rendering on these systems. 00:15:25.700 --> 00:15:29.200 But in the long term, it might be nice to solve the flow rate issue, 00:15:29.200 --> 00:15:33.700 maybe a second inline pump. The more important one is the GPU anyway. 00:15:33.700 --> 00:15:36.700 So let's get that started. This one I'm expecting to be okay. 00:15:36.700 --> 00:15:41.700 Oh, well that's great. This GPU is under 40 degrees though. 00:15:41.700 --> 00:15:44.700 And it's pulling 220 watts. 00:15:44.700 --> 00:15:47.700 Alright, gaming systems for gamers. Do they game? 00:15:47.700 --> 00:15:52.700 Casual 175 frames per second in Halo Infinite on medium 1440p. 00:15:52.700 --> 00:15:55.700 Oh, no. Oh, no, don't kill me, please. 00:15:55.700 --> 00:15:58.700 Oh, no, no. Oh, no, no. Got him. 00:15:58.700 --> 00:16:02.700 Oh, double kill. Oh, dang it. It's a lot easier playing on my kid's account. 00:16:02.700 --> 00:16:05.700 His MMR is not as high. Alright, cool. 00:16:05.700 --> 00:16:08.700 Well, that's enough of that. 00:16:08.700 --> 00:16:10.700 Time to throw this thing back in the rack. 00:16:11.700 --> 00:16:15.700 I may have made a slight mistake. What'd you do? 00:16:15.700 --> 00:16:20.700 I buttoned everything up before we actually tested the leak sensor that's in there. 00:16:20.700 --> 00:16:23.700 I can unbutton it. Yeah. Alright. 00:16:23.700 --> 00:16:27.700 Is this going to hold? Yeah, seems like it'll hold. 00:16:27.700 --> 00:16:32.700 Okay, leak test time. What if something catastrophic happens? 00:16:32.700 --> 00:16:36.700 Theoretically, all we've got to do now is take the other end of that barrel jack lead, 00:16:36.700 --> 00:16:40.700 hook it into this leak sensor, which you guys would have seen in the last video. 00:16:40.700 --> 00:16:44.700 Now I just... Pour some water in the computer. 00:16:44.700 --> 00:16:50.700 Basically, because it failed here last time, I put the leak sensor right there. 00:16:50.700 --> 00:16:54.700 So if this tube just comes flying off again, she's right there, bud. 00:16:54.700 --> 00:16:57.700 She's right there. Oh, my God. Are you actually... 00:16:57.700 --> 00:17:00.700 What? Oh, is it off? Yeah, yeah, yeah. 00:17:00.700 --> 00:17:03.700 Computer's off. Chill. Oh, my God. 00:17:03.700 --> 00:17:09.700 Okay. All clear on sensor eight, which is the leak sensor. So in theory, when you bridge these connections with water, leak detected. 00:17:09.700 --> 00:17:12.700 Okay. That's a lot of water. Paper towel, please. 00:17:12.700 --> 00:17:15.700 Oh. Okay. I mean, it's not that much water. 00:17:15.700 --> 00:17:21.700 Yeah, it would mean it would. It just is a lot of water for what I would like to put into a computer that has other computers running beneath it. 00:17:21.700 --> 00:17:24.700 Still registering? Still registering. Oh, wow. 00:17:24.700 --> 00:17:27.700 Well, that's really good. Actually, I can see how it's working. 00:17:27.700 --> 00:17:31.700 You don't need water between them. Just enough surface tension. 00:17:31.700 --> 00:17:34.700 On both tips. And then it registers. 00:17:34.700 --> 00:17:38.700 So that means we've got the distance just right on these. We don't actually need a ton of water. 00:17:38.700 --> 00:17:45.700 Right. Because the chassis is metal. It's using the chassis as a circuit, which is usually a really great thing to do with your computer. 00:17:45.700 --> 00:17:49.700 Well, look. It's only five volts. It should be fine. 00:17:49.700 --> 00:17:52.700 It's working. 0.6. 00:17:52.700 --> 00:17:55.700 Come on. Blow harder. 0.4. 00:17:55.700 --> 00:18:00.700 0.3. Keep going. I'm going to pass out. 00:18:00.700 --> 00:18:03.700 That would be funny. Oh, man. 00:18:03.700 --> 00:18:06.700 Oh, lightheaded. Oh, okay. It's clear now. 00:18:06.700 --> 00:18:09.700 If this registers a leak in the future, just come in here and start blowing on it. 00:18:09.700 --> 00:18:14.700 I mean, I was going to say, well, no, I got to come in here and start ripping power out of things. 00:18:14.700 --> 00:18:19.700 But I kind of don't. Well, the UPS as I do, but everything else is going to be shut down. 00:18:19.700 --> 00:18:23.700 I did bring you brackets to move your UPS if you want to do that at some point. 00:18:23.700 --> 00:18:28.700 I probably should. In a perfect world, we'll put in some concrete anchors or something like that. 00:18:28.700 --> 00:18:34.700 And we'll just mount them to the wall over there. And then what's nice is that'll actually give me another six rack units of space in the rack. 00:18:34.700 --> 00:18:38.700 Not that I need more machines, but you never know. 00:18:38.700 --> 00:18:46.700 I guess now's a good time for us to change out the coolant in these systems to just in case everything else wasn't enough, 00:18:46.700 --> 00:18:49.700 make real good and sure that she doesn't corrode again. 00:18:49.700 --> 00:18:52.700 Why is he so giddy about this coolant? 00:18:52.700 --> 00:18:57.700 This is G11 antifreeze, which conveniently is the same stuff you put in BMWs. 00:18:57.700 --> 00:19:00.700 Why does it always have to come back to BMWs with you? 00:19:00.700 --> 00:19:04.700 Like, are you on their payroll? I just looked at the forums and everyone was like, yeah, just get G11. 00:19:04.700 --> 00:19:07.700 That's the stuff that works good for this. So this is the real stuff then? 00:19:07.700 --> 00:19:10.700 Yeah, I mean, most antifreeze protects most metals. 00:19:10.700 --> 00:19:13.700 This is just like a high quality made in Germany. Good one. 00:19:13.700 --> 00:19:17.700 Is this concentrate? It is concentrate. That's a 10 gallon tank. 00:19:17.700 --> 00:19:21.700 Let's throw both of these in. It's blue. 00:19:21.700 --> 00:19:24.700 Wow. Look at that good stuff. 00:19:24.700 --> 00:19:30.700 One thing to note is that antifreeze does technically reduce the cooling performance a bit. 00:19:30.700 --> 00:19:35.700 Yeah, it's not catastrophic though. A couple percent realistically and we're not going like a 50-50 concentration, 00:19:35.700 --> 00:19:43.700 which is where you would really notice it. What we won't have protection against though is the non-conductive nature of pure water. 00:19:43.700 --> 00:19:47.700 This is probably going to contribute to the conductivity. Yeah, you didn't have pure water anyways. 00:19:47.700 --> 00:19:50.700 Well, it was pure enough that that system survived. 00:19:50.700 --> 00:19:53.700 No more corrosion. Corrosion be gone. 00:19:53.700 --> 00:19:56.700 Oh, hey, look at the down there. Oh, it's so pretty. 00:19:56.700 --> 00:19:59.700 I think we need to flush out the existing stuff though. 00:19:59.700 --> 00:20:04.700 I'm kind of thinking we stick the freshwater hose in there and leave the drain open for a while. 00:20:04.700 --> 00:20:08.700 Oh, okay. Flushing this loop about as interesting as watching paint dry. 00:20:08.700 --> 00:20:12.700 So you guys are just going to have to take my word for it that I swapped it out for the other coolant 00:20:12.700 --> 00:20:18.700 and take my word about our sponsor. If you guys enjoyed this video, maybe check out the last part where we looked at the aftermath of the leak 00:20:18.700 --> 00:20:21.700 and discovered all the corroded components.
