@@bvoyelr No. The pump itself uses water to cool and lubricate it. However, the engine is self contained and air cooled. You can remove the engine from this pump and run it stand alone without issue.
@@Hellsong89 No this was 100% one of Alex's gagillion ideas on how to cool a computer in the stupidest way possible. This is very on brand for an Alex video; lets not forget that he was the brains behind the entertainingly stupid series about making a cpu heat sink from scratch.
When you decrease the pipe diameter and increase the flow you increase the friction of the water against the pipe wall, which should be factored into your head pressure calculation. You need larger diameter pipe and fittings.
According to Bernoulli's Equation as the diameter of a pipe decreases the pressure will also decrease while the velocity increases. That means when you take a pump with 37PSI of pressure at a 1" diameter and a flow rate of 9539 l/h and reduce it down to a 1/4" diameter the water will leave the fitting at 5.8PSi and 74.88km/h.
The pressure losses in that loop must have been quite something. Ramming that amount of water trough all those fittings and channels :D Should have measured dP of the loop for giggles.
How long until they buy a slushie machine and try to pump slush through the system? Oh god, I've already said it out loud. They're probably on ebay looking for a slush maker right now.
For the next cooling experiment, try cooling a PC with a liquid metal loop like an early nuclear reactor. Liquid metals like Mercury and NaK (the preferred choice for cooling applications) can be circulated using a electromagnetic pump. The pump applies a current to the metal inside of a strong magnetic field, causing it to be repelled and move perpendicular to the magnetic field.
If only it was legal to buy mercury in the first place, specifically talking about Canada, not to mention the tens of thousands of dollars worth of safety equipment needed.
If they're completely suicidal then sure, use NaK, burn down the entire lab. Mercury sounds like a health and safety nightmare to deal with, especially if it leaks anywhere.
As someone who professionally works with high pressure fluids and their associated fittings regularly, this video made me oscillate from cringing to snorting with laughter in an unsettling but overall enjoyable way.
As someone who dosen't work with high pressure fluids and really only has basic physics knowledge, i bet that they lost a lot of that "flow" in turbulence. I would expect that you can't just push the water harder through the series of small tubes with complex geometry and expect it to not just dump all it's energy into the walls (and into itself). Also, shouldn't they have tried to pull the water throug the loop instead of pushing it?
@@raphaelambrosiuscosteau829 Most of the time you want to push liquids instead of pulling them. Pulling them lowers the pressure, which causes cavitation, which is bubbles of gas popping in and out of existence. Cavitation eats away at the tubes.
@@kylerichardson514 intuitively it feels for me that pulling would create more even flow through the loop instead of water coming out fast at the beginning and then dumping it all into the first couple of sharp turns it encounters. I do not know why it feels that way or if it's has any basis in reality though. Also, would've like to see flow meters at the start and at the end of the loop side by side to compare flow speeds.
As someone who professionally designed electrical control systems for industrial machinery and once witnessed what happens when a high pressure hose (50-60 bar, I think) blows off a fitting, I have a healthy fear/respect for high pressure fluids.
love how they include little tips like "dont leave your reguar pump connected or it could get burned out" Thanks LTT next time I hook up my gas powered pump to my pc i'll remember that one
Man, watching this video feels like watching MythBusters again, I like the chaotic energy that it has and the suspense of something going wrong any second, I like it, It would be great if they make more videos like this I lost it when Alex said "I think we can overclock the pump" 🤣🤣😂😂😂
In brief, at one point the show's ratings started waning, after which they initially cut Kari, Grant and Tory; then it became economically unfeasible to go on even with just Adam and Jamie. A reboot of sorts was attempted, but never went far. Adam now does RUclips, while the others have undertook careers away from the limelight.
The companies housed around LTT must have so many "What the actual F are the doing now O.o" moments.... P.s. that pump looks like it could use some water cooling.
Surprising how the loop held up under the pumping force. Having dealt with replacing the pump on the well in our garden, the pressure of a high-powered pump can be huge. This reminds me, maybe he could get a well drilled in his garden and use a pump in there hooked up to water cooling without a radiator. Wouldn't be practice, but would certainly be fun.

This reminds me of the Top Gear episode where they made a V8 powered blender and rocking chair. Maybe they can run a single water cool loop through multiple PCs using a gas powered pump.
As an engineer, I applaud the use of the Bernouli equation (even though it wasn't used correctly). As the owner of a plumbing company though, I can only shake my head. As a computer nerd, I'm happy with this video. Next time, use larger diameter tubes, shorter runs, an electric motor for the pump... If your building uses chilled water for the A/C system, you totally need a permanent manifold to connect PC cooling loops to. Overall, a 7/10. As my daughter's kindergarten teacher would say: "Keep up the great work :)"
I would say that he could outright just use the tapwater for cooling, and it might just do as good a job as this clunky oil drinking monster setup. After all, the tap water in a porperly designed building tend to already have enough pressure and waterflow in it, while such tiny pipes in these computers really doesn't need too much cool water at too high a speed to handle it.

I've already said this, and it's a very risky thing to say. Imagine you are on an island, and there is another island over there. And you want to conquer it. And they are ruled by a leader. "Oh but they are disciplined, and they obey their leader. It's impossible to defeat them." Ah, then we will impose democracy on them. Democratic propaganda! We will promote the most democratic way. "Oh, but they have nationalism! They will sacrifice themselves to protect their land." Ah, we will spread globalist ideology. Remove all notions of nationalism and patriotism, promote these ideas as evil. Turn them against each other so they will hate their own country and race. "Oh, but they also have incredible faith in God! They have such faith in God that they never abandon the front." Ah, then let's promote atheism and hedonism. Church time is over. From now on, only night clubs and pornography. They must be open about sex. "Oh, but the youth are healthy and strong. They're in formidable shape. They are the way the Creator made them: in his image." Ok then, from now on McDonald's, Coca-Cola, drugs, alcohol, video games. Let them be fat, lazy, weak, domesticated, undisciplined. We must abolish military service. "Ah... yeah but the other thing is that they are homogenous. They are a single people, a single race. There is no ethnic chaos." Ok, then in whatever way, we must send them boats with foreigners - whites, blacks, Asians, Muslims, Chinese. "But they have a lot of babies! 6 or 7 babies on average! They're happy to have large families!" Ok, from now on abortion, the pill. You have now defeated that island without firing a single bullet.
@@mduckernz It would need to be a custom block, probably with just a flow optimized chamber over the cpu instead of the microfins in most current blocks. big 3/4 in npt ports on it lol
Engineering-wise, I would have recommended a bleed-off line with a valve between the pump’s inlet and outlet. Start it with the bypass open (theoretically 0 down the load line), the divert the flow to the load by closing down the bypass valve, preferably gradually, until you find the limits your load can take.
+ an over-pressure valve to save your electronics. Though sometimes a bypass arrangement can be extremely sensitive to tiny amounts of change in the valve position.
10:05 Wait, SERIOUSLY?!?😱🤯💥🥶 You got a gas pump connected to a PC running at max power to get great thermals, and now you want to overclock the PUMP?!?!
With such a massive reservoir they could even run it closed loop for quite some time before the water gets warmer. And if they optimize the water container to be made of metal and flat and with ridges kind of like a heater at home, then they would have a giant passive radiator
Or they could re-use their radiator from the boiler they found a few years ago. If they’re gonna overkill anyway, might be good to bring that out again
They did remove the radiator, because they are attaching to the loop via the external fittings where the radiator was attached under the desk in the sleeper PC build.
@@Joshimitsu91 Oh yeah, that’s right. I forgot that the radiator was mounted under the desk in that build. Good catch. I believe the pump and reservoir were internal and still connected to the loop.
Always be careful fiddling with the max RPM limiter on these simple engines, cause they will rev to the moon and back if you loosen it too much. I blew a head gasket on one doing 9k RPMs cause these are designed for such low RPM cases.
Pretty sure the engine/pump were only planned to be used for one show anyway so pushing it until something broke was what they were trying, and if it had been the engine, they'd be fine with that.
I've done governor deletes on a ton of motors, specifically the predators and they don't usually rev past 7k cause of valve float, the main thing that gives before anything else is flywheel, piston and rod mainly
The intro is too iconic, it's basically a meme at this point i'm 100% sure that removing it is gonna hurt more than increasing watch time for like 8 seconds.
Linus is slowly evolving into “Red Green” with his wild antics. You can hear it in his voice, the slow evolution is his change in pitch with his “voices”.
No but the end did make me wonder if that if you lived next to stream or other water source it would be worth pumping water directly from there for cooling...
I feel caught. I have a fresh water well for my house that has a pump like that just powered by green pixies. Some hydraulic hoses and machined fittings. Infinite supply of cold water in the single digits.
I'm getting a total Steve Smith (Red Green) vibes from Linus around the 9:30-10:00 mark. Both classic Canadians, building impractical, gas powered "solutions" that I can't help but feel patriotic pride about as a fellow Canuck. Fantastic work from the whole LMG crew!
Would love to see a channel/ series where Alex engineer-splains thing in detail. Like a deep dive into the math and physics behind some of these experiments.
Yeah, as someone in the pumping industry i too appreciate the physics and math behind it. I'm sure more than a few other viewers are the same (though betting less than half would admit it).
Ok next, I want to see you try a electric automotive fuel pump. The brushless fuel pumps like the Holley units should be able to give you all the flow you desire! Plus you can control the pumps!
I like how the more excited Linus gets, the louder and more Canadian he gets, eh? And if the pump is getting hot, now you need to cool that. Thermodynamics and conservation of energy are a pest.
The advantage of the motor pump is that you won't notice your fan being too loud...

I've already said this, and it's a very risky thing to say. Imagine you are on an island, and there is another island over there. And you want to conquer it. And they are ruled by a leader.
"Oh but they are disciplined, and they obey their leader. It's impossible to defeat them." Ah, then we will impose democracy on them. Democratic propaganda! We will promote the most democratic way.
"Oh, but they have nationalism! They will sacrifice themselves to protect their land." Ah, we will spread globalist ideology. Remove all notions of nationalism and patriotism, promote these ideas as evil. Turn them against each other so they will hate their own country and race.
"Oh, but they also have incredible faith in God! They have such faith in God that they never abandon the front." Ah, then let's promote atheism and hedonism. Church time is over. From now on, only night clubs and pornography. They must be open about sex.
"Oh, but the youth are healthy and strong. They're in formidable shape. They are the way the Creator made them: in his image." Ok then, from now on McDonald's, Coca-Cola, drugs, alcohol, video games. Let them be fat, lazy, weak, domesticated, undisciplined. We must abolish military service.
"Ah... yeah but the other thing is that they are homogenous. They are a single people, a single race. There is no ethnic chaos." Ok, then in whatever way, we must send them boats with foreigners - whites, blacks, Asians, Muslims, Chinese.
"But they have a lot of babies! 6 or 7 babies on average! They're happy to have large families!" Ok, from now on abortion, the pill.
You have now defeated that island without firing a single bullet.
@@kcgunesq arctic sea water. They've done highLANder, now for northLANder
And a car radiator, for dat flow
Realistically the choke point will be the block, but still you get a massive surface area for cooling with those
@@mduckernz It would need to be a custom block, probably with just a flow optimized chamber over the cpu instead of the microfins in most current blocks. big 3/4 in npt ports on it lol
Engineering-wise, I would have recommended a bleed-off line with a valve between the pump’s inlet and outlet. Start it with the bypass open (theoretically 0 down the load line), the divert the flow to the load by closing down the bypass valve, preferably gradually, until you find the limits your load can take.
yeah some backpressure adjuster thing would have surely been interesting
+ an over-pressure valve to save your electronics. Though sometimes a bypass arrangement can be extremely sensitive to tiny amounts of change in the valve position.
YOLO!
I love how engineering worries about making a system better, despite the stupidness of it.
I've always wanted to find the limits of my load!
Alex: 20 minutes of math why this is a terrible idea
Linus: SEND IT! *proceeds to blow out fittings 20 times*
The amount of backflow that system is having to where it doesn't even flow is amazing
Gotta love setting up the gas-powered engine in an EV-only parking spot :D
Lets face it, its all coal powered at the end of the day.
@@GhostsGraphics At least EV's have SOME energy coming from renewable/more ecologically friendly sources
@@Lolks yes but even sources you're referring to which I'm assuming are solar are still made with horribly detrimental environmental effects
@@GhostsGraphics Hopefully perovskites will change that considerably.
@@GhostsGraphics bold of you to assume solar. Besides, I never said they were 100% ecologically sound.
Cool, now make it a V8.
Well someone forgot to change their account.
Whoa what
YES. Clarkson style!
@@petterikippo9863 how so?
LS swap your CPU pump lmao
10:05 Wait, SERIOUSLY?!?😱🤯💥🥶
You got a gas pump connected to a PC running at max power to get great thermals, and now you want to overclock the PUMP?!?!
The advantage of this pump is that you could have it setup really far away from your PC so that you have zero noise and efficient cooling ✌️👍😅
Since this is a kind-of open loop running at high velocity, I wonder if it might be more efficient to actually remove the radiator, etc.
@@GollumBetrayerOfHobbits just dump ice in the resevoir for uber temps
With such a massive reservoir they could even run it closed loop for quite some time before the water gets warmer. And if they optimize the water container to be made of metal and flat and with ridges kind of like a heater at home, then they would have a giant passive radiator
Or they could re-use their radiator from the boiler they found a few years ago. If they’re gonna overkill anyway, might be good to bring that out again
They did remove the radiator, because they are attaching to the loop via the external fittings where the radiator was attached under the desk in the sleeper PC build.
@@Joshimitsu91 Oh yeah, that’s right. I forgot that the radiator was mounted under the desk in that build. Good catch. I believe the pump and reservoir were internal and still connected to the loop.
"it goes without saying we wouldn't recommend this as a daily driver"
*switches to electric*
Who could afford it anyway with the price of gas currently.
Always be careful fiddling with the max RPM limiter on these simple engines, cause they will rev to the moon and back if you loosen it too much. I blew a head gasket on one doing 9k RPMs cause these are designed for such low RPM cases.
Pretty sure the engine/pump were only planned to be used for one show anyway so pushing it until something broke was what they were trying, and if it had been the engine, they'd be fine with that.
I've done governor deletes on a ton of motors, specifically the predators and they don't usually rev past 7k cause of valve float, the main thing that gives before anything else is flywheel, piston and rod mainly
9k? Okay guy 😂
Now I feel like we missed out on that opportunity.
It started to run out of fuel after only about ~500RPM, need to drill out the "injector" to go anywhere near fast enough to harm it -AC
Do beerbrewing glycol chiller next! Runs quiet, and can sit on the oposite side of the house.
I like that the gas pump is right next to an “EV parking only” sign lol
Whole building gas-powered water cooling setup when?
Yes
nothing could possibly go wrong
"I think we can over clock the pump!" haha Alex is golden, this is so much fun lol.
I’m loving this type of content you and Alex seem to be focusing more energy/money into!
Please more editor captions. I love it and it shows more character in the team as a whole. Love you, everyone at Linus
"we might be able to overclock our pump" is the most LTT thing I've ever heard in my life
the ultimate story: "water cooling a water cooling pump thats currently water cooling a whole pc."
Inception !!!
1:08 Linus is the Red Green of tech. Im sure Canadian folks will know what i mean.
Thanks guys, I never wanted to do this and now I dont need to.
Love these crazy engineering vids with Alex, and our boy Linus as well.
The intro is too iconic, it's basically a meme at this point i'm 100% sure that removing it is gonna hurt more than increasing watch time for like 8 seconds.
First time I've seen someone comment about this. I miss the intro when it's not there.
yeah i kinda miss it too
@Taistelu_pelto That's literally what memes are, this is why we enjoy them...
Alex's disappointment when bunta was brought out was palpable, i felt that in my soul.
One of the best videos you've made so far! This was a thrill to watch! Keep it up boys.
that smoke from the pump was perfectly normal. new exhausts always burn off some stuff the first time they get run hard.
Linus is slowly evolving into “Red Green” with his wild antics. You can hear it in his voice, the slow evolution is his change in pitch with his “voices”.
Just needs more duct tape
Oh, no. Red's shit-cainery is a whole order of magnitude off the scale from Linus's. We're talking Logarithmic scales of order.
If women don't find you handsome, at least they'll find you handy!
My favorite part about this is you just *know* there’s someone out there who’s going “hmmm that’s not such a bad idea…” 🤣
No but the end did make me wonder if that if you lived next to stream or other water source it would be worth pumping water directly from there for cooling...
yeah... me 😂😂😂
that person is me and we're all lucky I'm poor
I feel caught.
I have a fresh water well for my house that has a pump like that just powered by green pixies. Some hydraulic hoses and machined fittings. Infinite supply of cold water in the single digits.
"I think we can overclock the pump!!"
Linus: wait what
"I was hoping the bearings would blow off..."
"You booby trapped it?!"
Masterpiece.
that isnt what was said
My favorite part was hearing the benchmark reports over the sound of the gasoline engine.
I'm getting a total Steve Smith (Red Green) vibes from Linus around the 9:30-10:00 mark. Both classic Canadians, building impractical, gas powered "solutions" that I can't help but feel patriotic pride about as a fellow Canuck. Fantastic work from the whole LMG crew!
Honey the neighbors want to have a water fight!
Sure , just let me get my 2.5hp gas pump ready
👁️👄👁️
this is probably one of my favourite LTT videos so far. Its so chill and stupid but a great story
where we watching the same video? what part was chill?
Would love to see a channel/ series where Alex engineer-splains thing in detail. Like a deep dive into the math and physics behind some of these experiments.
Yeah, as someone in the pumping industry i too appreciate the physics and math behind it.
I'm sure more than a few other viewers are the same (though betting less than half would admit it).
Fluids 1 + LTT
"We wouldn't recommend this as a daily drive"
Oh shoot, I was just about to order myself a new pump
Linus and Alex chemistry is so so so good. So fun to watch
It's encouragingto see that even after all this years on the platfrom you still get more creative. Good to see. Thanks
Ok next, I want to see you try a electric automotive fuel pump. The brushless fuel pumps like the Holley units should be able to give you all the flow you desire! Plus you can control the pumps!
Mom: "are you running a lawn mower in your room?!"
Me: "no mom, im just gaming!"
4:34 WOW so cool and nice, very beautiful water sparkling.
"I think we can overclock the pump."
*gets out screwdriver*
The words of a true engineer. xD
Linus Tech Gear seems to be interesting, can’t wait for the episode with Linus connecting a PC to a V8 Corvette engine cooling it
Brass would've been way cheaper than freaking hydraulic fittings lol. They would've held up fine to that little pump too
Well but they're set if they would ever want to do 200 bar water cooling loop
PVC, Poly, galvanized...anything would have been cheaper than those fittings.
Princess Auto didn’t have a 1” brass fitting the day I was there picking up stuff for the project. The 1” hydraulic fitting was $10, for reference.
LOL understandable gotta do what you gotta do
Favorite part... They are occupying the EV Charging Parking spot... *Chef's Kiss*
Me: worrying my AIO could leak someday
Meanwhile LTT: let's blast water with 80km/h through this system
I had that fear so i removed my aio went air lol
1:40 Linus walking into work
I like how the more excited Linus gets, the louder and more Canadian he gets, eh?
And if the pump is getting hot, now you need to cool that. Thermodynamics and conservation of energy are a pest.
I think this is the first genuine _ey_ I've ever heard from a Canadian. I always thought it was a myth/joke
gotta hook up a cooler for the cpu cooler.
When Linus said "I juggle" I literally dropped EVERYTHING to see it. Was not disappointed.
i saw the story for this yesterday and instantly knew it was gonna be a trip, reminds me of that old radiator-cooling video lol
"I think this might have been the stupidest thing we've ever done" - Linus
I literally thought they were hooking up an engine to a PC for a second
how would that work tho
Isn't that just using a generator?
@@werter490 extra speed, adds 20 horsepower to the PC
aight well thanks editors I now look like an idiot
His Red (from red green show) impression is actually pretty spot on lol
First we had Linus' Home Improvement and now he gave us "Tool Time" with MOAR Power! Next he changes his name to Tim.
Binford 5000 Power Fist!
I like how they glossed over Bernoullis equation, which is probably one of the easier equations in fluid dynamics
They didn't even factor everything properly (pressure head loss)
Navier Stokes goes BRRRRR
1:45 what I imagine the Apple life to be like.
There’s an ad for a commercial water pump directly under this video. I think Google is telling you to kick it up a notch.
