  • Im pretty sure without a valve on one end of the tubes, the coolant in both tubes will only be moving one direction - away from the block as it heats up. And without sufficient coolant in the loop, with the presence of air pockets, full convection cannot take place effectively to cycle the coolant through the furthest end of the cooling block to really bring the temperature of the coolant down. In summary, add a valve, fill up the loop with more coolant and no air pocket. The heated coolant from the block will create enough pressure to cycle through all the chambers of the cooling block as the valve on the other end only allow the 'cool' coolant to return. Vola!

  • Water shouldn't be flowing out from both sides of the block. I would have imagined that thing has a check valve inside of it before watching the video. It works by keeping liquid, in this case coolant, flowing in one direction only. A check valve is the liquid equivalent of a diode, for anybody not familiar with them.

  • Tests a random water cooler on an 8700k what a god

  • felt like linus was talking pro-cowgirl position for a bit there. something about put the skinny one on top

  • Dear Linus Tech Tips... I don't envy you the ridiculous things you have to deal with, but I have a feeling your boss(es) must know how incredibly lucky they are to have you on their team. Anyway, a huge thank you from those of us who know just enough about computers to have ourselves a lot of...stressful, sometimes destructive moments. ;-) We appreciate your patience and savvy. Cheers.

  • That explaination on the straw filling with water was definately wrong. It does not matter if it was water, apple juice, pee or any other fluid because it has nothing to do with the surface tension at all. It is all about the hydrostatic pressure. What that means is that fluids try to keep a level through out their entire used space. Thats how most of the toilets all around the planet work. So basically you have water outside of the straw and inside of it. While both spaces are not fully seperated the reservoir with the higher level (initially the outside of the straw) pushes down to keep up the level with the strawer, but since water (like any other fluid) can be compressed (#physicsisgreat) the inner reservoir takes the pressure of the outer one and gets lifted. So both levels come to a tie www.engineersedge.com/imagefiles/u-tube.png This picture clearifies things a little bit. That is the U-Tube (no, definately no Pun here) Manometer visualized So it basically is about the level difference and the density of the fluid. No matter of surface tension EDIT: Still great video as always xD

  • Just like your car use an electric fan on the radiator.

  • 5:15 error 404 linus not found :O

  • ahh try adding 2 or more radiators and see if it does something to reduce the temp even further... however it wouldn't be a standard tower case that you can mount the cooling setup into.. at this stage an oil with a high boiling point may be the only liquid option that could be used however if you were 100-1,000 proof alcohol route for cooling you likely need to get it 5 to-5c making the solution pointless to consider the option.. at this stage the only 2 oils I would use if attempting to use a radiator type cooling setup that would be rice or olive oil or similar consistency..

  • I think the radiator need to stand vertical on the side so that one pipe will fill with condensated liquid and the other will not.

  • I guess vodka would work pretty well with this

  • What do you think about this CPU cooler? amzn.to/2D9ucDl

  • I like that rack for my computer.. Where can i get one? :)

    • Hold up.. I found your other video.. haha

  • Was that Desinc's profile pic at the start?

    • and yes its desinc's profile pic

    • its the scientist lmao

  • Try Splooge next time.

  • those fans need to be running.. u need both heat and cold to make a cooling go cycle..

  • 60 idle temps? Great! when can i get my hands on this piece of work.

  • The fluid is probably 3M Novec or something similar.

  • you mean I don't have to use my bicycle pump anymore?!? My feet can finally be free to do... other things!

  • I like how it takes him until the end of the video to rtfm

  • No comment about the tag on the back of his shirt? lol

  • I like how his sponsorship parts are less than 15s so I can skip them with a press of a button :D

  • Dem Eyebrows. Stop. Stop it now. YOU STOP THAT! STOOOOOPP!!! AAARGH!!!! RAGE!

  • I'm fairly certain that hitting it with a hot load is going to lose you your monetization...

  • raijintek? the reason I had a dead 970? 10/10

  • 9:11 wait, what am i watching?

  • can we please get a review of the huawei matebook x pro 2019

  • Says "zed" at 1 minute and "zee" at 2 minutes...can't you even Canadian?

  • Soo, it's a AIO Cooler that is designed to encourage hard work

  • Do CPU cooling with Gallium

  • Why does his builds always look boring asteticly

  • Cool concept but boiling point for water is too close to Tjunction, perhaps consider Acetone which boils at ~60c? Do also look into thermal conductivity of other liquids and you might actually be onto something here

  • Low enough pressure for faster boil, correct mix for lower boil temp, but what they are missing is a long enough tube to allow the liquid to air cool without a fan. Think of a massive copper or even silver curly straw. (silver allows better heat transfer then copper) The Liquid would boil up then at it's apex form of vapor begin it's downward water slide to cool off. I would add in a larger reservoir before the two tubes with the fat tube leaving straight up and the smaller tube entering from the bottom instead them both entering/leaving sideways. It would be a massive water cooler, BUT silent with no moving parts

  • Or you could just leave your pc alone

  • 0:43 i know ur Canadian but cmon man

  • use peltier element as cooler

  • why arnt the fans rejecting heat

  • bigger smoother tubes!

  • I don't think that the pipes in the radiator should have been at the same level, if the radiator was on it's side so that one pipe was higher then you might have had better circulation... probably best also if the pipes where connected diagonally... still not efficient enough but this might have increased the efficiency significantly...

  • would borax help with surface tension

  • Hey would mercury work instead of water?

  • No Signal Please check the input connection

  • Im looking to build a water cooled pc and am interested in Barrow Cpu blocks, any one have any reveiws or advice i dont see a whole lot of reveiws

    • that's because they are chinese. you won't find a lot of review about Bysky products for the same reason

  • Am I the only one who noticed the droplet of the fluid escaping at just after 14:00 ?

  • That motherboard in the beginning of the video without its protection plate on made me slightly nervous.

  • All these people working there and you can't even script and streamline the video...

  • It is called aluminium

  • What tool did he use to simulate load?

  • you know what is funny? When you say the only way to find out is sitting through a sponsor shot. I just skip forward in the video.

  • What about using valves to control the flow of liquid. But personally I'd prefer cooler temps than total silence.

  • They could have used the liquid that has long chains of molecules that others use to show how liquids pour itself. Once it starts it keeps going in a loop. Polyethylene glycol I think

  • Love a star wipe

  • 5:10 ur welcome

  • The problem with arguing that water cooling is silent is that it still requires air cooling (fans) to dissipate the heat from the radiator. I still think that the Dark Rock Pro series or Noctua's NH-D15 is the proper solution to high end cpu cooling. Pretty darn silent, great temps, and low maintenance. Air cooling is still the sensible choice for the average user. Unless you consider water cooling a hobby in itself that you find enjoyment in, the cost-benefit analysis is more favorable towards air coolers.

    • very true. but watercooling helps whe you have a lot of high end parts, that you want to OC, in (relative) silence. custom watercooling is an art, if you do wrong it could be worse than aircooling. but done right, it's thrilling to have your PC at full charge (CPU + multi GPU), and no more noise than at idle. No aircooling solution can do this but yea it's very niche.

  • one pipe should be above the other just by logic.. wtf

    • you should also put the fans sideways so the thick tube entry is a the top. This will minimum back flow from the top pipe


  • Oh Linus, you're so weird and creepy, I love you for that.

  • So wouldn't you want the radiator sideways so the pressure from the water forces it in one direction. Then the hot water will travel to the top and cooler water to bottom. Then cooler water would prevent hot from going through both? I could be wrong I'm no expert.

  • You guys really need to do a build submerged in Novec fluid

  • Seems like a dye that changes color with temp would be handy or at least entertaining with the clear tubing

  • I mean to be honest you'd really have to be a huge b****** to care about a lil bit of noise that is mostly muffled through the case AND your headset since literally everybody wears some nowadays.. Compared to my old PC I have a watercooling pump from Corsair (H100x) and even while playing heavily it's around 65°C and barely makes any noise.

  • Remove the fans from the radiator and watercool it. That way it will be truly silent! Yes, a watercooled silent watercooler.

  • if there would have put the hoses one on each end of the radiator and mounted it vertically would it not heat siphon way better?

  • that intro spooked me a bit xD

  • Lawl this guy

  • I have a cooler that has a pump that sits on top of the CPU and it is so quiet and when i am rendering video it keeps my PC as cool as an air cooled PC when its on idle.... so im not sure what the problem is....

  • the water is a moving part and a point of failure smh 🙅

  • 3m has a novec fluid that will do this efficiently, it's just insanely expensive.

  • everyone ever: >feels another linus advert segue coming on >furiously taps L key

  • .. if you: -mostly fill a normal loop with isopropyl alcohol -hang a bit of tube below the inlet of the cpu you should have a pump-les setup.. if i'm not missing something...

    • Worth a try (on a Pentium 4 or something similarly worthless and hot), but i have minor doubts that you can get to 80-100°C core temperature with a fluid with a boiling point around 80°C, due to Intel's propensity to use Mozzarella for thermal interface.

  • Its basically a txv for a refrgeration unit. It probably has refrigerant and a disc valve in it. The refrigerant turns to gas creating pressure to either open or close the disc. Depending on build and or type of refrgerant

  • i saw where u were contemplating using a refringration evaporator to cool a computer. Just know the humidity is gonna be ridiculously bad

  • 5:21 HALF LIFE 3 CONFIRMED *now with better graphics and new characters such as linus*

  • I have an issue with 1 of my 2 ram sticks that run at 75c should I try cooling it with boiling water?

  • Is that desinc i see?

  • as a former process plant operator, this is sooo cringe.

  • Old office, who dis?

  • 5:17 I can feel Linus sexually abusing me just from that look

  • its funny to me that this is better than anything apple has in their products

  • What about LTT diy with alcohol? Go go go!

  • You clickbaited me, you Crash Bandicoot looking motherfucker.

  • My ears hurt every time linus tries to explain something physics.

  • convection has NOTHING to do with surface tension. /facepalm

  • If they wanted it to start moving immediately, they could just cool a Pentium 4 with it

  • I strongly suspect the the unit is sealed to keep atmospheric pressure out, not to keep fluids in. Water at Mean Sea Level will boil at 212° Fahrenheit or 100° centigrade. If you go higher in altitude, the altitude results in lower air pressure. This allows the fluid in water to more readily turn into its gaseous state. This is where this system becomes ingenious. It takes a great deal of energy to change a fluid from its liquid form to its gaseous form. A lot of energy is lost when a gaseous fluid turns into its liquid form. If you can cause water to evaporate (boil) at a lower temperature, i.e., < 100°C, (that's Alt-0176 for those who want to know how I got the "°" symbol. Look up ANSI codes.) then you can cause the water's natural tendency to evaporate and condense to happen at lower temperatures. Evaporated water will carry heat up and away from its source of heat, and the radiator (or condenser, in this application) will do its job and allow the ambient air to carry away the energy the gas is bringing into it. Once enough energy is lost, it will again condense into a liquid and flow back down to the cooler. If you notice, the cooler block has two different size openings. My couch engineering isn't such that I can be 100% sure about this, but I think the wider opening facilitates gas flow away from the CPU, and the narrower opening is better suited for the liquid to flow in. Essentially, I'm just going over Air Conditioning Systems 101. I'm studying for my Airframe license to finish my A&P so I can work on airplanes. Someone else likely knows this subject better than I do. All I really need to know is whether or not there are bubbles in the sight glass to work on A/C systems on Aircraft. Still, I hope this explanation is mostly accurate, and that it helps someone know what's going on. I doubt I'm the first person to bring this up, but I did want to mention is. Just finished watching the video. Speculations on my part: Its atmospheres aren't reduced. That's about 14.7 psi in there. They're using water. Water boils at 100°C, and that's about how hot the cores got. I think if they had a way to keep the atmospheric pressure out, it would work far better and they could still use water. Rigid tubing would make the process much easier. This would make the system not as good for non-custom loops. I see why it has been 3 years without a product yet. Freon might help. I don't know enough about Freon to know if it flows fine without a pump. Chances are it does, but I'm not the one to ask. This would be easier to work around if all manufacturers involved standardized radiator, CPU, and GPU placements. This would be better for an environment where one kind of computer needed mass production, or for someone who had the tools and the technical skill to fabricate their own fluid lines. Once the lines are fabricated and properly crimped, all one would need to do is evacuate some of the pressure out of the system and water should be just fine. On paper, you could keep all components at whatever temperature you wanted. Again, my education only goes so high as to make me a mechanic or a technician, not an engineer.

  • When it leaks, your house has to be decontaminated by a biohazard crew.

  • Solder with an "L"... Not sod-her LOL

  • it's a neat concept.

  • @Linus Tech Tips. not sure if you noticed but at 14:02 on your video you see a water drop fall off of one of the hoses! thats not good. its Faulty :p anyone else see the water drops?

  • What I would consider doing, is adding a tesla valve to one of the tubes, and increasing the diameter of the tubes, as well as searching for a tube design that specializes in low friction of fluids. The tesla valve is an invention of Nikola Tesla… It's a one way differential pressure valve, which causes them to encounter high resistance when trying to travel in one direction versus the other, and it has no moving parts, so it's perfect for a clean, closed-loop system like this. The suggestion to increase the diameter of the tubes that move the fluid from the CPU block to the radiator, is because larger tubes generally = less resistance. (Probably something to do with the boundary effect.) But I suppose it won't help up to a certain diameter, because reasons.

  • I presume it's liquid, not literal water.

  • They should try to use liquid metal with that. I do wonder how much it of a help it would be to the temps.

  • It looks like there are actually two tubes per tube, like the gas is going up in the middle and fluids are dropping down on the sides.

  • 03:47 Scary...

  • 25+ staff to create this video .... yikes

  • Large tube on top to carry the vapor, smaller tube on bottom to carry the liquid return. Gases have a higher specific volume than liquids. Also need the vapor return line to be on the top side of the radiator so that the liquid return can be more easily gravity fed. This is a common type of set up for steam condensing systems or other industrial applications. Especially for refrigerant cooling applications on large scales where the efficiency vs capital cost makes sense.

  • I mean.. you know the fan is a moving part too.. lol

  • Put coolant in there. They're radiators, right? Not for a car, but ones for motorcycles. (Edit: You can use a larger rad to get more surface area, yet the entry and exit points at the radiator must be on opposite sides to better allow the cooling.)

  • Does anyone else see sparks at 9:50?

  • fill port of some short
