He did explain that a custom loop is needed to achieve better than air cooled performance. He also explained in the previous video that water cooling is better when the system is under short burst loads.

Water's thermal capacity isn't really what makes it a good cooling medium. It's thermal conductivity is what allows it to transfer heat from the CPU to the radiator fin. Thermal capacity just slows the temperature rise of the liquid between the CPU and the radiator.

[@Sett86]

There are 3 parts to cooling a device: 1) removing the heat from the device 2) moving the heat carrying medium around 3) removing the heat from whatever takes care of 1) and 2) Liquid coolers are very good at 2) and 3), being easily able to utilize several thick radiators they can easily keep the medium just a few degrees above ambient. But they suck balls at 1). Air coolers, or more precisely high end heatpipe coolers, on the other hand, are awesome at 1), but with limited space to dissipate it in place, and prohibitive cost to move it around, they suck at 2) and 3). The guy, who invents flexible enough, durable enough, cheap enough heatpipes to utilize case mounted radiators, is going to be rich (NOT the same radiators that we use for liquid, although that would be awesome too). Also, the end result: It depends. As it is Water can graciously take care of much more heat than air, but air can be more effective for more down to earth use cases.

One of the other factors that can help determine if you should go Water cooled or not is the environment you are going to run your system in. If you live in a hotter area where ambient temperatures can get pretty warm even with AC going having a Water cooled non over clocked system can actually help to prevent the system from creating extra waste heat due to how efficient the water is at controlling the temperatures - the fans don't need to consume the extra power necessary to spin faster for your system.

Modern air coolers have heat pipes with liquid in them. So, they are in fact partially liquid coolers as well. The difference is that heat pipes cannot be extended or bent so that you can place the large flat radiator on the right place in the case.

High end air coolers are quieter and simpler than custom liquid cooling, and even AIOs. The only genuine downside is if you move your computer around the heavy heatsink can be problematic, but if you don't move your computer, then the air cooler is the premium experience.

[@theunboxingexperience3480]

@@aaaman7 As mentioned by Linus, there are actually air coolers like the Noctua NH-D15 that perform better than many water coolers and even though it's relatively more expensive than the other air coolers out there, it's about the same price as an AIO. On top of that, it is so much easier to tell if the fans of the air cooler are spoiling as compared to the pump of an AIO, which brings me to the third point. An AIO, with an additional pump (on top of the fans that are connected to the radiator), has more components that are subjected to wear and tear and failure. Bonus point: It is cheaper owning an air cooler like the Noctua NH-D15 than an AIO in the long run as all you have to replace on an air cooler are the fans when they eventually spoil but you'll have to practically replace the entire AIO when the AIO fails to work. So that's 4 reasons why I would much rather have bought an air cooler than an AIO. Hope it helps you understand.

Water is an intermediary step between the air and the hot heatsink copper. The specific heat capacity of copper is 0.385 J/g°C while water is 4.179 J/g°C The density of copper is 8960 kg/m³ while water is 997 kg/m³ If my math is any good that means that water holds about 1.2 times more heat in the same volume of space than copper. Perhaps more importantly water is easy to spread out over a larger surface area of a multi fan radiator than designing a combination of heat pipes and fin stacks that's efficient both thermally and in space requirements. Worth mentioning. Air density is roughly 1.2 kg/m³ water has 830 times more mass than the same volume of air. When it comes to specific heat capacity air is 1.01 J/g°C or about 4 times less than water. So water can act as a very easy to use buffer to store up the heat from spikes of high wattage, doing the same with just copper, aluminium and heat pipes is much harder and typically results in more bursty high RPM work for the fans. Aluminum heat capacity is 0.902 J/g°C and density is 2700 kg/m3 which I think results in roughly 1.7 times less heat capacity per unit of volume than water.

Water cooling is not better because better is a relative concept and encompasses various domains other than performance. I prefer longevity, safety and low cost over a few more mhz. That said, for the price of a decent 2 fan AIO, if you were to add it to the cost of your cpu or gpu, you could probably afford an upgrade which would give you more performance than an overclock.

I am a gamer But I do not overclock and I use watercooling and here is my reasoning on it: I worked in Quality control at Philips Electronics for years, one test was the lifespan test, How do we know a device will last for 10 years in only 1 year? Well we make use of a physics law that is so easy they will not teach you this in schools or universities, the law is simple, heat up anything for 10 degrees celsius and every Physical and chemical process will speed up by a factor of 2, so we tested these devices in huge walk in ovens that where like a dry sauna at 80 degrees Celsius, that is like an average of 50 degrees, or 5 times 10 degrees or 5 times 2 the normal physical speed of lifetime, in most countries during the summer days meaning 1 year is actually 10 years. So when someone explained it to me I asked, does this also work in reverse? Like 10 degrees colder makes my lifespan 2 times longer and it turns out it does, which resulted in my 10 year old PC, still performing at high speeds way after the intended 5 years most things last.

@@MichaelBerthelsen It doesn't change the results at all it just shows that they were flawed. Like Linus said in this video water and the other liquids used in liquid cooling have a much higher thermal capacity than the metals used in air coolers. The only way an air cooler could actually have a higher thermal capacity than a water cooler is if it was of higher quality. I think that explains why Linus's team got the results that they did in their previous video.

[@MichaelBerthelsen]

@@jordanski5421 They used quality air coolers and quality water coolers in the test. Neither cooling SYSTEM has a higher or lower heat capacity. The water has a higher heat capacity, which means it heats up more slowly. But if you're removing enough heat (in watts) using the quality air cooler, having a water cooler won't make a lick of difference. It may slow down the rise to max temp., but it'll reach the same max temp as air over a period of an hour or so. And I doubt most people use their PC's for only an hour at a time before letting it cool down to ambient.

For all of the people in the comments yelling at Linus for how this contradicts the LTT video from a while back, that video was referring to the raw performance and noise of AIOs vs air coolers. Not Custom loops vs air coolers.

*TL;DR:* In 99% of cases, it's not. Air coolers are cheaper, quieter, perform identically and have less points of failure. Sure, water is better on paper, but in reality... just go air.

[@fragalot]

So the one thing you forgot to mention about AIOs is they tend to last about 5-7 years because the pump will eventuality fail, and the liquid inside will get mucked up. Air-coolers last forever (and some are also liquid cooled with vapor chambers), though the fan on an air cooler will eventually fail, they are easily and cheaply replaceable, unlike the water pump of an AIO and they aren't really repairable anyway. There's also a huge price difference between AIOs and air-coolers too, and I'm not willing to spend $150 for something that last 5 years, when all the other components in my PC have lasted for much longer.

[@tallpaul9475]

Change the title to "Why is CUSTOM Water Cooling Better? (AIO still sucks)", to be less confusing and conflicting with an earlier video made it sound like air cooling methods were better.

[@stilles342]

So, I think there is another advantage of AIO/Custom loops: Even if a water cooled system gets a few degrees hotter after hours of gaming, it will take a loooong time to reach maximum temps. And also it doesen't reach low temps very/super fast after ending a demanding task (like gaming). This allows the components to expand and contract much slower and therefore more gentle. The expansion/contraction cycles are not as abrupt as with an air cooler, which dissipates it's heat very fast, due to it's direct cooling of the heatsink. I think this might be more gentle to the solder, thermal paste and ultimately the components as a whole. Please prove me wrong.

[@Midknight0122]

Me: does material science for a living Also me: still avidly listening to Linus explain permanent dipoler nature of water Linus missed a trick not becoming a teacher, or maybe he didn't considering what he must earn. oh and water is better at dealing with heat spikes due to heat capacity of water, for steady load air is as good or better, in fact they said as much in a previous vid.

[@12Emilos12]

Heat capacity only matters for the transient periods of heating. During steady state the only thing that matters is how well you can get heat from the cpu to the radiator/fins and away from the radiator/fins to the air. Both water and heat pipes are good at moving heat, so you just want a really large area of fins/radiator and lots of air flow. With water cooling you can keep adding radiator and basically get the return water to reach ambient temperature. This is very expensive though.

So it typically goes like this: (extreme OC solutions) Direct application LHe > Direct application LN2 > Direct application CO2 > Phase Change > Peltier (Termoelectric cooling) behind a custom loop > (normal solutions) Custom loop > 360mm AIO > 240mm AIO / NH-D15 > 120mm AIO / Other sinks like Evo212 > Garbage coolers like Wraith or Intel stock. Overall water is better than air cooling as water has much higher thermal density. This is the reason why many things from most car engines to nuclear power plants go the water route for cooling. One huge advantage of a radiator is literally carrying the heat away from the system.

Noctua NH DH-15 and you don't ever have to buy a new cooler. It works eternity, it cools better than most AIO water coolers, it has lower noise, it won't leak, and having the best air cooler allows your CPU to use less energy. This saves you money, allows better overclocking, allows longer life for the CPU, Motherboard and PSU. Air cooling also cools down RAM and components that deliver power to your CPU. I had really expensive custom loop, but then my pump crashed and I either had to wait for a two weeks or buy air cooler at the same day. I bought the Noctua NH DH-15 and I was stunned at it's performance. It's really worth the money in the long run. Water cooling really isn't. Also you should buy really high quality PSU. It is more efficient, gives cleaner electricity which wears the components less, and cause less heat, and possibly even better overclocking. And good PSUs work eternity.

Love the science behind this video sir. I was very impressed with your teams work to write a good scientific article about water vs. air cooling. (:

Water cooling it's better if you download more RAM, CPU and graphics. If not, stick to your potato mayonnaise regular cooling system.

[@davidgriffin79]

It's not the size (thermal mass) of the heatsink that's important it's how much surface area it has. A heatsink with good thermal conductivity (copper) will quickly spread heat energy throughout its mass. If there's sufficient surface area and forced convection, the heat sink will quickly reach a steady-state condition with a ΔT between the CPU and ambient surrounding air. A large thermal mass heatsink, but with less surface area (due to fewer fins) will reach a steady state but at at higher temperature (smaller ΔT). Forced convection of air over the heat sink increases the Heat Transfer Coefficient (HTC), as the HTC is a function of flow rate; and the more surface area, the more heat energy can be transferred to the surrounding air. The old Zalman jet engine type heatsinks are an example of a high surface area heatsink.

[@oplkfdhgk]

i mean technically even air coolers are watercoolers because of heatpipes :P

Most heat pipes do not have anything in them. It is just a tube.

[@MihzvolWuriar]

Either better performance or lower noise, both are good reasons for getting a water cooler, my old rig came with a extremely noisy air cooler, I still blame it my current ear problems on it (it sat at my left, my left ear have lower performance than my right ear, ant it still have noises [ringing and white noises] they're manageable though), took me too long to realize the benefit of a water cooler, bought one, no more noise, very quiet year around, quieter than the cooler on summer, never overclocked it, though.

[@jacobkelley257]

You should mention thermal conductivity as well since generally metals conduct heat much better (according to wiki) but like you said, they don't hold as much heat. So if they are both heat soaked the metal air cooler should dissipate the heat quicker

[@jerrythefish1622]

Too bad you proved yourself that air cooling is just as effective

[@rnegoro1]

And less risky.

[@jerrythefish1622]

@Alexander Deris if it starts to leak then water plus electronics does not mix well

[@cubanamerican22]

Pro HVAC tech tip, if you have water cooling beef up your water pump, extend (and insulate) your pipes and set your radiator in front of an AC vent in line with the flow of the air. Voilá! Your CPU will be cool in many ways lol

No need to watch short answer: Water steals heat 20-25 times faster than air.

Summer time is when the AIO is good for me in upstate NY. it gets pretty hot. even with A/C in the window.

I would definitely say that Evaporative cooling plays a much larger role in why a swimming pool remains cold than why you stated in the video.

[@clarityhandle]

"But why is water cooling better?" **Proceeds to give chemistry lecture**

[@fracturedraptor7846]

TLDR. Water cool if you overclock. The higher heat capacity will keep temperatures down while traditional coolers take longer to dissipate the heat at those levels, excluding the outliers like the DH-15. Went with a sealed AIO for the CPU on my new build because it looks sexy. Probably would get the same temperature control with a DH-15 but I was worried about torque. The 2080 ti isn't exactly a light weight. Remember the days when a GPU was hardly bigger than the 56k modem boards?

[@DikkieDikism]

For overclock reasons its "generally" better. For normal use so without overclocking and just standard CPU settings and turbo settings, an air cooler is actually pretty good and if a good brand usually even quieter.

[@kcStranger]

So, I got my doctorate with a theoretical chemistry research group that spent a lot of time studying water. The explanation of hydrogen bonding and water's high heat capacity in this video is far from complete (as it needed to be), but I was pleased to find that it was essentially correct.

6:27 pools feel cold because water is such a great thermal conductor compared to air that even at slightly below body temperature, heat quickly flows from your body into the water resulting in a lower point of temperature equilibrium on your body
