 Before you tell us this is an incredibly stupid idea, trust us, we know, Alex did the math. So according to Bernoulli's equation going through this adapter right here. What's the freakiest thing I've ever done in years per hour. None of that's important. What's important is that we are going to use this two and a half horsepower gasoline powered pump to water cool a PC. And no matter how stupid it is, you can't wait to see it. Just like you can't wait to hear about our sponsor. KiwiCo. KiwiCo ships out crates that contain hands-on projects for kids to help develop their creative confidence and problem solving skills.

Wow, that's actually a lot faster than I thought it would be. Take a guess what it will be with this pump. I don't think I have to guess. I think you put it here. Oh, you didn't. You bastard. Holy crap. 1800 watts? Yeah, that's two and a half horsepower. 50 kilometers an hour. 74.8. Holy. We could conceivably be talking about this thing blowing the tubes off of our blocks then. Oh yeah, that's what this entire setup is about. I love that it's called PowerFist. This here is a pump for real men. And this is not just a pump. This is for transferring water, my fuzz. This thing could hold a column of water 85 feet in the air. Use as intended. How little fun is that? Wow. This is the size of a fricking lawnmower engine. A lawnmower engine with a pump on it. Now this ain't a pump. This a pump. Now obviously we're gonna need some adapters. And that's where this hardware that we probably paid way too much money for comes in. Ahoy there morons. How much did this adapter to adapter to adapter to adapter cost us? I'm not sure actually. This was Jamie's solution. And I agree it's not a bad solution. Is this one of the ones where you mix the oil in with the gas or? No, you just put it in here until it overflows. I am pretty sure these are gonna leak, but it doesn't really matter. We'll just tighten them until they don't. I don't think it works that way actually. It does, they're NPT. What is this? I think it might be compressed air fitting. Yeah. Oh wow. That's got a greater inner diameter, but it's also going straight from like fricking here to that. I juggle and the last one left in my hands we use. Okay. Okay. We use this one. Okay, cool. Ha ha, you did it. You brought an adjustable wrench. This is a perfectly fine time to use an adjustable wrench. Yeah, it is. You can round these and it's not really a problem. Holy crap, is this it? We just hook it up and go? Well, we need the suction side. And a professional sucker always brings his hose. It's long. And ribbed. My pasty nerd skin cannot take the sun, especially after wintering for six months. Check this out. We've got a big garbage pail because we figure that makes sense. There's a lot of gunk floating in it. Yeah, Jamie took a filter through it as well and kind of cleaned it out. It didn't work very well. The first thing we have to do is just hook it up and go, right? Oh yeah. All right, let's put some gas in. I love this. This is good safety right here. You should always have your fuel stored a safe distance away from anything that could possibly spark. Yeah, Jamie suggested that we should get some gasoline on the hot exhaust that's right beside it. No, he didn't. Ah, yes, prime. Do we have a little like pump-a-doodle for priming it? I really don't know if this is the way to prime it, Alex. I watched a couple of YouTube videos and they said that this is the way to do it. Okay. Priming means getting the water from here to the actual inlet of the pump. Cause you run this bad boy dry, you're not gonna like it no matter how much choke you apply. Okay, that almost never happens to me. Oh, hey, how you doing there buddy? It's not actually sucking yet. This is really not a good way to do this. Alex, you're crying out loud. Here, if I just help you line it up, I think it'll be okay. My hand slipped. It did not. Okay, that's good. You're like Charlie Brown with the football, getting back in there again. It's a dated reference. Woo-hoo! Whoa! Sorry, I slipped. I slipped. Not 100% sure that this PC is going to, well, it's already dead, so it can't not survive. But you know, the fittings that are in here, I don't know if they're gonna be up for the task. We do have these ones from Alpha Cool that have little metal barbs in them that should be fine. But we only have those in Boonta the Slaver BC and I don't know if I wanna hook that up to this. But first the test on the broken hardware. Yeah. Oh, that's leaking. Whoa, oh shoot. Maybe turn it off. Yep, I got it, I got it. Holy bananas. I might've just forgot a fitting. Oh, Alex. That would do it. Primo. Turn it off a bit. Wait. Ah! Ah! It really seems like it's not flowing that fast. Let's give her more juice. Yeah, it seems like something's wrong. Something's leaking. Ah, damn it. Sorry. I just changed into dry clothes. I think there's just a tiny bit of a leak in here. To dry clothes, I think there's just a ton of pressure in the loop. Yeah, it seems like a lot of pressure and not a lot of- No, a lot of flow. Yeah, it's weird. And I think there's something back here leaking or something. Is this radiator leaking? I think there is a fitting on the bottom of it. That's definitely where it was coming out of. Okay, let's get that tightened down. Whoa, this just slipped off too. These compressions are not the right size for this tubing. I was hoping it would blow off when we turned the thing on. Well, it did. You booby trapped it. Which makes me wonder how often he screws me over like that. Do you think we should switch to our higher flow rate ID barb over here? I kind of feel like we should. Yeah, maybe. Let's do that. What are you doing? What the crap? You see this play here? Oh yeah, that's kind of weird. We didn't learn anything. There's a lot of vibration. Here. Oh, the thing fell out. Oh, this is going really well. Why is it so bad? You know what? It's designed for a hose. Something that's supposed to have a lip around it. I don't think the flow rate's much faster anyway. No. We might as well just go back to the other one. Is that full bore? No. There we go. Why is there so little like, ah, shit. What I'm doing right now is I am using these quick connects at the bottom of the Bunta sleeper PC. We're gonna connect our gasoline powered pump to this loop. I was really excited about this moment, but now that it's actually time to pull the rip cord. This is my favorite PC I've ever built in the five years I've been here. The D5 that's in here, the normal computer water cooling pump is having absolutely no trouble pumping through our gas powered pump. So we should disconnect that pump. Yeah, I was thinking about that. I don't know if we can. Really, Alex? Like I know that you have pretty small hands, but like. Oh balls. I wanna see some real good performance here. Let's do Furmark. Let's also grab MSI afterburner. We can probably overclock it a bit. I don't think that'll be necessary, Alex. No, but this is the shunt modded GPU. It can pull 800 watts. God, it stinks. Where's the exhaust? Oh, I'm right next to it. At the lowest setting here, I'd say our gas pump is actually not materially different from a normal water cooling pump. Looking at the flow meter, she ain't really doing that much. How's our GPU temps looking? 42.8 degrees. Okay, that's pretty low considering we're running Furmark, a stress test. How many watts are we drawing? So about 600 watts right now. This is a really good water block. Well, maybe I should run Furmark at a higher res. Ah, there we go, 370. So that's a bit over 700 watts. And we're up to 44 and a half degrees. The question that remains is by cranking this sucker up and increasing our flow rate to the point we're at risk of blowing our tubes off our fittings, will we get a performance benefit? Like me, do you feel as if your whole life led you to this moment? Yes. Okay, we ready? Yep. Jeez. What are we at? We're drawing one and a half degrees. Yeah! I'm giving her more. Oh, that was it. Oh, shit. Wow, it's really going though, hey? Yeah. 25 degrees on the GPU is pretty impressive. I really want to do a 3D mark. I gave it a little bit of an overclock. It should be stable, it might not. We'll see. This is next level, right? Most people start gaming, their fans turn on a little bit louder. We start gaming. You got to give her more gas. Make that dinosaurs. Look at them go. Ha ha ha. That's awesome, hey? Not really. We might be able to overclock our pump. Wait, what? Oh, there we go. She's really going now. Oh, we're linking a bit. Hi, I think that's coming from in the PC. What? This is terrifying. Oh my God, is it overheating? Is it smoking? It smells really bad. Whoa, whoa, okay. I think this may be the stupidest thing we've ever done. Yeah, probably. We got our score. What's really impressive here, that graphic score is like a hundred off of when I had the chiller hooked up to it. Really? That's freaking crazy. We only hit 44. And it drew at max. About 760 watts. Yeah. Un-fricking-believable. I think that D5 pump might be dead. She's not moving. No signs of life. Wait. Oh, she's trying something. Well, let's get the shutdown. Oh, heck yeah. I think she's back. Oh yeah. There we go. That's awesome. You're all right. She's alive. A really important thing to note about the performance we saw though, is that we were using pre-cooled water. So we didn't have to deal with all the extra heat that a gas powered pump would be dumping into our loop. We got all the benefit of fast flowing water, but none of the drawbacks. We, I think it goes without saying, wouldn't recommend this as a daily driver. KiwiCo is a monthly subscription service to help introduce and make STEM topics fun and engaging for kids of all ages.
