 Come on, you can go faster than that, can't you? No. So you've just got your brand new PC and you wanna do some overclocking, but that like, that tiny air cooler that you have is just not doing it. So you could get like a radiator, a pump and a reservoir, but all of that's pretty damn expensive. So what if you just buy the block and hook it up to your sink? Well, Linus said that's a bad idea, but he's on vacation. So, let's do it, yeah. Madrina's Coffee blends specialty cold brew coffees into 15 ounce grab and go cans for your convenience. Check them out and use offer code LINUS to save 40%. 40% at the link below. So first thing we need to do here is just get some baseline reading. So what do we have in here, Jake? So this is a Intel Core i9-7900X. We got a Titan XP, not P, but Pascal, same thing. We got an AX1500i, which is super overkill, but really what we need to look at is the temperatures here. So in the hottest core, we're looking at about 56 degrees. This is at the stock clock. So I guess, should we overclock it first? No, let's wait until we get the sink going, right? Yeah, let's just see how it performs compared to the sink and go from there. And that's with a 360 mil EK water blocks rad. Oh, oh, that's my favorite technique. Just give her a good blow. There's some stamina here. Jesus. Dude, I don't think it's gonna seal very well. Does it even stick to this? Does it matter though? I bet you if we put a fitting on that end of the tube, it would be easier to like mate the two metal surfaces together. Oh, why did you let it go? All right, let's just. It's stuck in the sink. I'm going to get another fitting. This guy, what an amateur, hey? I got it, we don't need Jake. Okay, we're just, we're just doing it. Alex only video now. Yep. We most certainly, oh geez. It's a bad idea. I'm gonna go get some tuck tape because I don't think that your tape is good enough. Dude, what happened last time you used tuck tape? Is there video footage of that? It's leaking. Yeah, it got dropped. It was fine until we put it under pressure. It was fine until it like needed to work and then it didn't. I don't think they engineered this around being able to do this. Okay, so do you want to hold it and I'll tape it? Sure. Let's cut a piece off here. What are you taking now? That's our return. Our return valve. That's how we'll prevent that. Perfect. Cool. It's working. And I guess you don't have to wait for this to get up to equilibrium either, right? Yeah, there's no equilibrium. The water is not recirculated. We are just at it. Oh my God. So at idle, we're sitting at about 14 degrees. Four. So this is how you get subambient. You remember that? It shouldn't go up. It's gonna go up some. Like a bit. Like my guess is 38 average. That's really good though. Oh my God. Okay, so we're getting, hottest core as of right now is 40 degrees, which is what like 16 below what it was before. Yeah, 56 I think was the hottest core before. How's it going? It's good. You like your water cooling? What is it? It's the best thing you've seen all day. Coming out of the tap? Yeah. Yeah. What's wrong with that? It's a waste of water. Well, it's not too bad. I'm upset. But look at our temperatures. Our hottest core on a 7900X is 40 degrees. That's not very many degrees. Wow, Riley, you're so insightful. I guess this is the best way to water cool a PC after all. You ready? Three, two, one, go. You gotta keep it straighter. Okay, so we're gonna have to measure right from the bottom of the meniscus. And stop. So that was 11.8 seconds. We'll be using 150 liters per hour. I think before we overclocked it, we can take this to the next extreme. How is it gonna get better than this? So we can't hook it up to the fridge. Well, but you know what we can do with the fridge? We can just take yonder bucket of water. Okay, so I'm kind of missing, but you get the idea. So yeah, we've got this $22 submersible pump. So the idea is basically we have a bucket, we fill it with ice, we put the pump into the bucket of ice. Then sink goes to bucket, goes to pump, goes to thing, goes back to thing, drains into the sink. Oh, we want that over here. Why, what is with you and putting the water back in the thing? Because we're gonna have really cold water. So you want to have the cold water kind of like doing its thing in here. Yeah, then we're just dumping hot water into the cold. It's not going to get like above ambient in the time it goes through there. All right, fine. And I don't think we can keep up with the pump with this. This is true. Is there a speed setting on there? All right, so. Pump is getting plugged in. Now. Is that pump supposed to be submerged? Yeah. Oh wow, dude, that thing is kicking water. Dude, these lines are so cold already. We're gonna kill the CPU for sure. No. This board is gonna be donezo's. So we're sitting at about. Oh, sub zero baby. Yes. Dude, we have a finite amount of time before this front. But yeah, we're looking at about three, three ish degrees. Is it still sub ambient? Oh no. Okay, so it's 22 degrees in here. Yeah, our hottest core at the moment is 24 degrees. So we aren't sub ambient. We're damn close. We're doing better than we did with the chiller. And so like the total cost of this whole thing would be like. A cheap AliExpress block. You can get those for like 15 to 20 bucks. And then $22 for the pump. You can probably find a cheaper one. And we are a solid what? 30 degrees lower than. We were at 56 before. More than 30 degrees lower. Than a triple rad from EK. Five gigahertz, baby. Oh my god. Oh my god. 90 degrees. Oh my god. Wait, what? I think Cinebench just keeps crashing. So. Why does it go to 90? I think that we need more voltage. We have 1.4 volts. What do you mean? We can't do more voltage? It's crashing. And the answer to crashing is more voltage. I think we need Anthony. Hey Anthony, we need you. We don't know how to overclock. Oh, you know how to overclock. Kinda, yeah. Sure. Yep. We're gonna leave this up to you. Okay. Oh. See that's what I was hoping that non-committal answer would prevent. Okay, okay, see you later. Enjoy, buddy. Oh boy. Okay. Okay. That's a thing. All right, so let's go Ida. The voltage. So sitting at max of 11 degrees at the moment. Our voltage is 1.375 and 2.15 input. Hey, it's working. Ah, damn it. Does it work? It's just crashing. No, it dropped down to 1.0 actually. Oh, it does work. Hey, look at this. There we go. So we got a little lower voltage. We're basically at similar temperatures to what we started with, except we're at five gigahertz now instead of 3.9. Come on, baby. Oh. Damn it. Dude, there's so much water on those tubes now. Oh yeah, geez. We don't have much time. Oh, 4.8. Ah, come on, baby. Oh, you can do it. We're at 101 on one core. Yeah, so it's immediately overheating. We're still at 4.8, baby. No. We can drop the voltage to like 1.35, I guess. I am concerned that this is just a fucking processor. Yeah, it might just not be a very good overclocker. I'm just so disappointed. I want a five. Yeah, well, sometimes you can't have nice things. I guess that's part of the story, right? You bought all this stuff, you can't just go return your CPU, because well, actually, you can definitely do that because Amazon, but you're not supposed to just return your CPU because it doesn't overclock well. So I guess we'll get to the best we can get. Oh, I had XMP on. Oh. So? Sweet. Do you think that would hurt it? Yeah. Oh, David. David. Oh, oh. Oh, we're screen capping. Did I do it? Did I do it? What did you change? I changed everything to auto. Wait, what's our, wait, go back to our thing. What is our, we're at 4.3? Why are we at 4.3? What did you even set the, what? Why did it? What? What? Okay, so, well, this is disappointing. All right. 4.8, baby. It's, how did this, what did you change? You just set it to auto. Auto every, that's how you overclock X299. So there's no way at all that this could be done with just regular water cooling. No. Would be like 4.4 maybe, 4.5. This right here is definitely like what you put in your forum post. But yeah, this, so it works then. Yeah. If you just want to get another four or 500 megahertz to hopefully 500. 6,000. Yeah, baby. 60, 88. Yeah, almost 6,100. I think we can push it a little further. You think we can go further? I think we can do- We are at 93 degrees there. Well, I think I'll try to leave the voltage another 100 megahertz. I'm gonna give her, I'm gonna give her 1.385. Oh God, it just turned off. Let's unplug it. Oh, maybe it was fine. Our last kick at the can, if we can't do this then, oh. Holy. Oh, it's doing it. No, it's not. It's done. It's done. So it's conclusion time, I guess. If your goal is to just get the craziest Cinebench score, craziest 3D mark, maybe plugging into a sync is the way to go. Yeah, this worked surprisingly well. And D-Lid. Yeah, definitely D-Lid. D-Lid it, because we absolutely destroyed the triple rad and the whole thing cost like 50 bucks. And you could probably do it for cheaper. Yeah. If you get an aquarium pump from like a hardware store, or used, buy one used. Actually don't do it. Yeah, please. Probably don't. Do you need to create a beautiful website without the hassle?
