 Recently, Alex and I shot a video assembling what is the very first Linus Media Group manufactured CPU water block. Now, of course our objective though in all of that was not to build a CPU water block because quite frankly We could call up our friends at AlphaCool, EK, Swift, basically anyone and they would do a much better job of it than we did No offense. Yeah, none taken. The objective was for us to water cool a red 8K camera But baby steps, right? So this was doing something pretty normal where we could basically clone a Chinese design And then just put it on the CNC. Today We kick things up a notch with this. We're gonna water cool something a little unusual our 10 gigabit 12 port network switch from Netgear that was actually the first 10 gigabit piece of equipment that we got Well, not counting like network cards like a switch The hot docks uses the Ergodox design which keeps you comfortable typing away for long periods of time and Features QMK firmware and hot swappable key switches. Check it out at the link below So this is it They don't get Their network switch anymore in the camera then. Yep. Just unplug it. Yep. All right. Well, oh Crap, we were supposed to do the sound test first. That's kind of the whole point if you guys It's really loud Yeah, this is gonna be a very inexact unscientific test here 56 decibels on boot up. Okay, let's water cool it How much does Steve pay us for all this product placement that he gets on our channel like nothing So the reason that network switches are really loud and run really hot is not necessarily because The hardware inside them it has a ton of power draw or anything like that It's because cooling them is a real challenge Most network switches even at the prosumer level are in what's called a single you Which is the I don't know the universal unit. That's where the you comes from I'm just kidding. I made all of that up for height in a rack so that means you can only use these wimpy 40 millimeter fans and A lot of the time you also don't have a lot of ventilation holes for whatever reason. It's funny. I actually brought my own Handle because I was using this for something Before we started So I can help oh Man, I just stripped that bit That took a long time I'm gonna go get a bigger screwdriver Oh, there's the one he stripped Bloody hell I just stripped this one, too See I just had to go in straight That's what my mom always said What I'm actually really looking forward to this I have it's It's a funny thing because like computers the first thing I do with them is open them up like laptops and stuff But it's never occurred to me to open up our 10 gig network switch at least this one That's still not oh Oh, there we go So up and back cool. Holy crap. There's a lot of stuff to cool in here. What is this? Are they ripping us off? Huh? Is there another port that they don't put on the front? Maybe they were just afraid of having it be 13 So here's our power supply that we're definitely not going to touch or even get close to so my intention had been to keep it One you mountable though Oh, okay. Yeah, but then just have like tubing out like quick connects or something and then like an external rad Okay, I mean that's one option. I'm not married to it though for whatever reason in my mind I was picturing kind of like this goes on here. Yeah, and we just like Cut two holes for tubing and then mount a rad like right here Like full like like engine block showing through the top of the hood muscle car muscle switch And then I guess if you really wanted to we could put like some t connectors in there So you can make it a one-hue have it go out the side So it looks like every one of these heat sinks Is hard mounted so there's screws going in from the bottom of the PCB in this whole thing And from the bottom of the PCB and this whole main board needs to come out before we're going to be able to remove Any of this now to be clear this is not as expensive as a red camera But this is still today What like an 800 network switch or something like that? I have no clue Yeah, let's be careful with it because I can't remember how much it costs either. It's not cheap though I almost wonder if we could just get away with putting little copper things on here sort of like you said But then run a heat pipe just straight across all of them if we used a ball nose bit That was the right size we could cut a channel Right in the top of it the right size for the heat pipe. Yep, and then just solder it on And and then we managed to spread the heat out that way. Okay, and that way we've just got this big spreader That'll carry the heat theoretically, hopefully Towards our cooling. Yeah Okay, wait a minute. What? Oh, it was all soldered on. There's no way how could they possibly be? That's gonna be a pain in the butt should I go get the soldering iron yeah, all right What do you think the chances are that they're soldered on and then epoxied underneath? I was just thinking Oh, we do have a way how hard do you think it is? Just snip those Oh, uh There Easy as pie Easy as pie I should have been wearing eye protection for that Brandon you're wearing glasses, right? Yeah, I think we can get in there and just give her like a little snip You got to be kidding me. Oh you you're doing it. You actually did it you actually did that work so well Everybody's got eye protection Everybody's going to be screaming so much like they got so mad when I just like hacked off the dvi connector and that's like a bunch of pins That one hit over there and then landed over there This is so dumb what we're doing Yeah, not bad So you got a couple challenges These look like they're up a little high so we might end up having to kind of go around them. Um, also Not all these holes came clear so we might have to either pop them back out or actually desolder them properly if we want mounting points for our block Yeah Your copper slab to cover it is probably the simplest way Here's our main cpu block and then We do a short heat pipe here and a long heat pipe here. This is actually gonna be pretty difficult Yeah, I don't know why I wasn't thinking it would be difficult, but it's going to be quite difficult But it's going to be quite difficult Can we can we do this where I actually here hold on hold on hold on can we can we pretend that I had Something to do with this and i'm like, oh god. What did you do? Okay, you can do it. So How did you do that over the last week or so he created? this fantastic Well, I mean what what would you call this? Model? Yeah, it's just like a little model. So we have the switch here All the critical measurements for our water cooling is in there and you ended up buying new calipers for that. Is that right? Uh, yeah Is it the big daddy caliper? No, it's the alex's calipers And these are really fancy because They're just very repeatable and expensive Um, we had problems in the past where I would measure a bunch of things and error would stack up So I guess there were a couple problems that we had to solve here So the first is that I was pretty concerned that having this many heat sources on one heat pipe would cause problems Um, so we have this paper here that sort of solved this for us Which is an investigation of thermal characteristics on a centered wick heat pipe with double heat sources Basically tells us you want your heat sources to be as close to the condenser as possible So our condenser is effectively this segment of the heat pipe right here where it will be thermal Epoxy to this copper plate, which is going to be water cooled And then I guess other things Jonathan from ascend ceiling contacted us, uh And we have a heck ton of o-rings like He's just he's just been raining o-rings on us So so we have better o-rings this time. Yeah, and also his card stock is amazing. Like look at this. It's quality Yeah, can we get some of this? No, and yeah, we have new o-ring lube. So basically Nothing can go wrong. Yeah. Well things can go wrong, but that's what we're about to get to the hard part though Is that we have to actually machine this so how do you machine a rounded groove? So we have a ball nosed end mill. So that's just like it's round on the end and you just kind of Kind of just like that which was this was like surprisingly hard to get to work properly So big shout out to cj from autodesk. He really It's going to be like half a sketchy one Because we can't go any lower than 78 000 rpm On our cnc router. So really we should be using a mill for this We should be using a mill for this but we don't have a mill because they're expensive Yes When you're going to cut metal You need to make sure that every single time that the tooth comes around you're actually like cutting out a chunk of metal Or it's just going to rub and it's going to burn it out really fast So since we can't make the tool spin slower, we need to run it faster We're being safe, right? Yep I don't want people yelling at us about our cnc Yeah, do you want to plug in the air compressor? Yeah, I'd love to We do have actual mist cooling now. So everyone that's saying you should have cooling. We already have cooling Well, you can definitely see the shmoo here So is this just getting like more and more legit every time we do a video? Yeah, basically This is leaking Yeah, it got dropped So we're ready. Yep Can I press go? Uh, not yet I like to feel like I'm helping And that's the tool that we have. So yeah, here we go That is not that clean looking No Ah No And we're done. So what happened there? There was the piece of copper that we're trying to cut shifted which means that the entire tool path that alex laid out is now offset by about three quarters of a centimeter so It's possible That we would have ended up with something usable, but our thermal transfer is not going to be great I mean if it had held down we would have something here anyway I could probably be usable. Yeah, but that's really bad for the tool and we have to make four of them And we're back this time with a bit of a new plan so Now we have bolted our copper plate down to the bed We have also made some Canadian engineering repairs to our reservoir down here it no longer leaks Thanks to some hand mix epoxy and uh, we have done away with our plan to make rounded grooves Because we don't have a mill we only have a router So why don't we just let the work speak for itself instead of telling them what's gonna happen? I can press go now, right? um Hey Hey Let's see the finished product so this is going to be the top of one of our blocks This is going to be the top of one of our other more different blocks This is the block we made last time which is still here again for some reason we're using the bottom of it Oh, we're just reusing it. Yeah, I mean why dull your bits when you don't have to oh is this it? Yeah So this is the moment of truth right now Perfect it really is actually Yeah, it's 0.1 of a millimeter oversized good work i'm happy with that um, I guess we just need to clean these off and And tap them look at that. It just looks so good underneath completely see-through. We didn't bother facing at this time That should go there. Yeah, that goes right and then we'll have the three that go down the middle here That's a lot of copper Now you told me pro mode was going to have the heat pipe on the bottom so that we were like heat pipe direct touch cooling Yeah, are we doing that with this one? No, not with this one. Oh, that's going to be version two We mean version two we need to get this done because eds mad that they don't have a switch for their ingest crap, but Yeah, ingest crap. We don't we don't need these videos But yeah, we're going to have to redesign this guy and alpha cool is coming up with those like the server sized Just heat sinks. So those are going to like go in the side and it's going to look super legit But until then we're just going to like have atlantis tech 2 style just like below the ingest station Do these screws go through? Not quite We don't have to widen the holes in the pcb do we Are you kidding me Well, it's potentially going to be the quietest and coolest switch on Like everywhere arguably a switch that doesn't power on anymore is very quiet and very cool Now this bit might actually be too small that went super well, nope, we're good what that was it. Yep. That's that's all that we needed Oh nice Nice We should probably give this a little dusty here. Yeah something Yeah This is pretty bad Yeah, it was definitely one of the worst ideas i've ever seen like am I just going at it with this I like legitimately straight up Forget how to do it. Um, what about this time? We just like Clamp it like this. Yeah off the table. Yeah You can just kind of get this on the side like like so and blammo blammo Okay There are a lot of people that were really mad last time that we didn't use the drill press to do this So it would go down perfectly straight Oh, yeah, that would be smart wouldn't it? Yeah, it really would Nope, no Wait, what the crap is this? The crap is what? This hole doesn't go all the way straight through the drill press had an issue Yeah, that's good. Okay. This is the really bad one. I don't know about that. Well, you'll be able to tell from the bottom Oh geez, what did you just do that is that's pure carnage right there. Oh god Oh god, that's a lot of acrylic on the floor Yeah, uh these don't quite line up well like do you want to tap those holes again oh they're all the way over here Oh crap Okay, so we're just kind of doing the same thing as last time then yep Accolade me extra cyano on the side and theoretically it will seal We're asking for a lot of tight tolerances to line up here, yep We're gonna put that Through a plastic washer Okay, so that goes there then we do another plastic washer I'm assuming Um, yeah Okay, then we do a nut. Yep Not me They're So I've realized something really unfortunate Where this right here screws in I thought that it was just like nuts on the back that came up Yeah, but it's actually screwed right into the chassis Yeah, I don't know if these can come off Yeah, I don't know if these can come off. Oh I can't believe that you got all these holes to mostly sort of line up I measured it Are you guys as excited as we are to see if this thing is still gonna work? I am I'm amped Assuming that we didn't kill it It's gonna work pretty well. I mean we didn't do anything that bad to it Not really We're not gonna actually power on the switch We're just gonna power this pump and then make sure that nothing leaks Did you fart? Yeah, but like a couple minutes ago It's really lingering Oh, well, I'm sorry about that It's awkward All right. Well given that our system here has passed our exhaustive three-minute stress test Would you say we're ready to start? Would you say we're ready to power it on? Yeah There's a light David Oh, it's green. Identifying it's green. That means 10 gig link. Oh, yeah test And there it goes indeed boom Okay, so now what? Now we we actually get to put it together? Yeah, I guess so. Okay Hey damn I have screen cap going so you don't need to come over here There is one more test though, it's possible that we're not making good contact with Anything like we actually don't know that just because it's working. That means it's working Well, I love that our fans just say failure because they're not they're all plugged in Question for you though. Yeah, uh, did you get new like quieter 40 millimeter fans to replace these? Well, I guess if it's just open can we just stick like a 140 on top or something? Yes Yes, we can. All right Yeah, so what we can do is we can take this puppy Put it on Do a 140 millimeter cutout Mount the radiator to that So that nothing could slip through put the fan on top and put a fangirl on Disassemble this and put it in and i'll get a hole in here. Sure. Cool Are you gonna measure where the hole goes? Yep So, uh, I think we're almost done here um Okay Speak for yourself because we need to power the pump Oh, I think what we have to do is plug in the power supply and start probing Um, I was in panic mode and I put it in the air meter All right. Well, let's see if anything still works 12 volts. Yay. Wow. It's a christmas friggin miracle. Okay, so So that is ground and 12 volt So ground is the far left 12 volt is the third theoretically orange is ground What the black is positive 12 volt and yes jake it matters Okay I have good news though Look what I found What in the balls is that this is a six pin pci express adapter see these two pins It's a six to eight pin adapter. We can use these two wires To find our 12 volt power and then splice that onto the power connector for the pump So then as long as we get the right two pins, then we're good Okay, so what did I say orange was ground black was 12 volt? Yep neat theoretically When I plug in the switch it will turn on with no sparks Power leds lit Uh and theoretically Okay more sanity check time I have 12 volts here Oh Huzzah What a nightmare and I just needs to get to connect to this. Yeah Other than the hole in beginning This is actually surprisingly like sort of properly done. Yeah, like sort of properly I mean, there's no proper way to do something this stupid Yeah, like I guess if we could get a couple zip ties in there like yeah 100 pro All right A couple ltt cable ties get that shilling in there. Oh, yeah A bit concerned about putting this on okay we have to kind of go over the tubes and Just not slice them Oh, but can you get your hand in there when it's like that? Uh, yeah, I have small hands Here if you let go here I can help you align this side You might as well have these ones kind of come up similarly, you know Okay The best part is that like it looks so good on the inside like it's pretty like Pro like all machine and stuff and on the outside. It's just like straight like ghetto like Not even the same color tubes hot rotted like it's not very space efficient Um, it's very heat efficient. Yeah Work faster. No It's a lot quieter. Yeah, did you see how quiet it is? I don't think I ever actually heard it It was like Yeah, it was pretty loud It's still working temperatures are actually lower. Yeah, well, we have a fan running on the radiator now So that's an improvement. Yeah, we're looking at 27 and 28 degrees compared to like 51 and 42 before it's dead silent And let's do a quick file transfer here Here we go I'm liking it Backblaze is an unlimited cloud backup for macs and pc's that's just six bucks a month.
