    Water cooling can keep your whole case cooler. No mentioning of that.

    Not really a good control here. You need the SAME FANS ON EVERYTHING. You are comparing air cooled to water cooled but if they have different fans you can't claim that comparison... Not only that you are comparing a different number of fans to one another... either change the N to Corsair fans or change the C fans to Nactua. You did all that work and the results are useless because the fans are different on each set. But even then you have to address the fact that a three fan setup will theoretically take more voltage to run at the same speed as your air cooled two fan setup which will add heat to the inside of your case.... to eliminate this you should only compare the two fan liquid cooled to the air cooled, since your air cooled has two N fans. This should get CLOSER to equal fans and the air cooled and water cooled can then be examined without the fans as a variable. Other numbers are interesting but can't really be compared to one another as air cooled vs water cooled! Furthermore, if you are comparing temperature, you should be running the fans at the same speed and compare the temps that the same speed of the same number of fans produces.. if you are looking for sound, you should set the fan speeds to produce the same CPU temperatures and then compare the sounds that were needed to produce the same temps. In this test you are looking for which produces the lowest temperature as your primary test. To do this you need two exact fans on each type of cooler. Then you need to run the fans at the same speeds and compare temps. This will give you which setup cools better at the same speed. If your air cooler then cools better at the same fan speeds, you have more excess cooling capability than the water cooler and conversely if your water cooler cools better at the same fan speeds, it has more excess cooling capability. To simplify the problem with what you did... and you stated this.... if these coolers are even anywhere close, the much better Nactua fans will invalidate your experiment.

    my phenon II 1090t was liquid cooled with a cosair H80.. had a push/pull config on the radiator.. idled at 39c and with all 6 cores @100%, never went above 55c in a room that was 25.5c.. my 4Ghz Alienware idles at 31c and with all 6 cores, hits 59c

    I ditched water cooling when I had the hassle of a defective waterpump.
    Far easier to simply swap the fans out for a new one.

    The day when i made my first gaming pc i realised that in india you ought to have liquid cooling where in summers temp reaches 47-48 deg c ambient. I got CPU restart every 15 min in summers my amd fx 8350 radeon 8570 were like oven even playing for 15 min. Then i threw the stock cooler and got h100i liquid cooling. Never again did i faced any prob reg temp.

    My brother and i actually had a failing cpu watercooler so we opened it and it had bubbles and dirty stuff. Then added engine coolant and cleaned it up now it doesn't get hotter than 70 degrees. 8core cpu with 1 fan radiator.

    What I found with switching to water cooling, I use that single fan Corsair H50, is that the video card works not as hard to keep cool. I have mine one top sucking air out. So that the total noise is less. The video card fans are way noisier. With the water cooling, unless I'm gaming the video card fans don't come on, unless it is a hot summer day.
    One note, I did stack a fan on the inside and outside the radiator.

    Should I then replace my U12S with U12A if silence is my goal? Strangely Linus Tech Tips is the only test that showed such extreme noise difference between U12A and U12S. I looked up the decibel test results on other websites and they're practically identical.

    Not true. Swapping to a beefy 360mm AIO was the best decision for me. CPU temps have been ridiculously low even during the crazy heatwave we had this year. I'll never go back to air.

      @mankind and destiny lol, what makes you think the pump will fail? They're stress tested to last for years (at least a decade) even if running 24/7.
      I would probably have upgraded my PC multiple times by then.

    Water cooling isn't dumb, AIO coolers are. If you're going to add the mechanical complexity / potential failure points of a water cooling system, you'd be stupid not to at least do it in the form of a custom loop that can actually cool all your relevant components and eliminate any high-speed fans. An AIO cooler can't do that-- your GPU, motherboard chipset, and anything else that requires active cooling in your setup are still going to be covered in fans (worse, these kinds of applications often use the little, higher-RPM varieties). If you're just going to cool a CPU there's no point doing water. The benefits come when you can use massive radiators and low-speed, high-pressure optimized fans to pull the heat out of a water loop that plugs into all your components: no more CPU fan, no more GPU blower, no more chipset fans. Sometimes full-cover blocks for the motherboard if you go with a board whose OEM does a water-cooled version or buy something popular enough that one of the waterblock manufacturers will do one.
    High-end air coolers are great, too. Seems like Noctua is the new Thermalright. I used to use on of their XP120s to cool a Q6700 without even using a discrete CPU fan: just having that heatsink adjacent to a case-fan was enough if you weren't overclocking. A nice air-cooler makes a thousand times more sense than any AIO water cooling setup: it's cheaper and involves virtually no maintenance. Blow the dust out of it and clean your fan once a year and you're done. AIOs are just for people who want to be able to say / show their PC is water cooled without having to do any work themselves. They're full of low-quality components, they underperform, and they fail to deliver the quality of life improvements that water cooling systems are meant to provide (near-silent operation without sacrificing performance). They're pointless systems that exist for bragging rights / "gaming street cred."
    Cheap / low maintenance: OEM air
    Cheap / low maintenance w/ good performance: high end air
    Expensive, but quiet and good performance: custom water
    Expensive, annoying, amazing performance: exotic shit like phase-change or chilled water (have fun dealing with condensation any time your coolant temperatures are below the dewpoint, which-- if you're going for any meaningful temperature drops-- is going to be all the time unless you live in the goddamn desert)

    I like my custom triple fan watercooler...cpu & gpu water cooling blocks 15$, triple fan double core radiator 30$, 12v brushless Pump 13$, g1 fittings and tubing 20$, hyperlube coolant enhancer 10$... 3 cosair sp120 that came with my case 3 pin pwm . temps 21c idle 45 full load. My gpu and cpu are Y split and in the same system. I also have a amd style rgb fan thermal cemented to the cpu and gpu waterblocks just in case the pump fails (10$). My setup is a little extreme but still well worth the price i paid, you can get smaller radiators etc to make this cheaper but I would never go back to air after this, get some quieter fans. e5-2660v3 with 1660gtx

      use automotive pressure clamps to save 20$ G1 is aesthetic with function but they are expensive and are prone to fail if you done tighten them correctly. Automotive clamp will less likely fail and can handle 100psi + dependent on your tube material.

    This sends such a wrong message. Linus is such a sell out. I guess you just don't know how to set up liquid cooling properly because it's the coolest thing you can literally do to your PC. You can create art with it. Oh and by the way it LIQUID COOLS YOUR PC. This video is TERRIBLE!!!!!!!!!!!!!!! Obviously Noctua is paying him to do this. That's how YT works. And that's why YT is beginning to suck. Soon as someone gets big it all goes to there heads and they stop making honest videos and only make what "they" want. You don't have to tell people it's going on, so every gullible person watching thinks this is ACTUALLY Linus's opinion about water cooling. When really it's either not, or he's just too afraid to do it. I honestly can't figure it out. If there's anything you shouldn't do, is overclock. There is no point whatsoever unless you wanna destroy your parts way faster. Anyways, I'm done.

    I don't know about anyone else, but I like to hear my fans on my radiator. Hearing them makes me know they are doing they're job. I have 3 floe 360 fans on my rad, and my 980ti classified has 2. I blast them all and I don't see a problem with noise what so ever. so I don't see what the big deal is when it comes to people talking about noise levels from your pc. I mean don't get me wrong I'm sure if you had 3 5000rpm fans blasting that could be a lil bit noisy. But I think I would like that even more. hahahah

    I have the H100i with a couple noctua fans on it for my 4790k. I cant imagine it gets any better than that for cooling. They didnt get into the advantages of swapping out for some awesome fans on a AIO like the H100i. Built this PC going on 5 years ago! and it still going strong. Not one problem with the water pump, Knock on wood.

    From my own personal experience I've always gotten better performance and audibles with a water cooled all in one. What I don't understand is how the noctua can be so good if it's all aluminum which it appears to be in the video. Also if it's all aluminum why the hell does it cost so much? There's like $0.30 worth of aluminum there.

    Okay, time for some honesty. Can someone, anyone, PLEASE tell me why "Noise" is an issue?! If I owned a BEAST of a machine that can work and process lightning-fast, perform realtime-renders incredibly fast at extreme sample rates and export 3D animations at beyond, optimal speeds, I frankly do NOT GIVE A @#% how "noisy" it is! HOWEVER, if the noise actually MEANS something negative, then I get it. So, can some computer-savvy person give me some guidance on this issue? Does noise mean anything negative or significant?

  • Doc Holliday
    Doc Holliday 8 days ago

    What if you put the NH-U12A on the radiator and measure the fan speed on both to keep the same temperature.
    Also you forget that the 3 fans in the case which keeps its internal ambient temperature down so the fans on the CPU cooler works.
    So essentially you have 5 fans vs 3 fans + pump on the water cooling solution. I think a Fair compare here would be to turn of the fans which moves Air into the case.
    Now with water you also get the ability to move the heat somewhere else like outside the case.
