    Another PSA: Cavitation isn't happening in your CLCs/AIOs. The motors aren't that powerful, you'd need to go to industrial applications for that. Cavitation is when water vaporizes on the surface of an impeller, which isn't happening in these hobbyist-level motors. With cavitation, air isn't in the voids formed but water vapor is. With CLCs/AIOs, it's just air bubbles getting pulled through the loop (not cavitation).

    Great video, guys!! The BEST I saw about water cooler. I wish I saw it earlier. All my questions and doubts were answered with this video. This is for sure the best and most elucidative video about water cooler setup I have ever watched. And you guys really showed the air and the liquid working in the cooler. Other videos only talk about stuffs and don't really show what happens inside the cooler. Great work, guys! Congrats and thanks a lot for doing this video.

    Steve Burke: "Let me spell it out for you."

    Mfrs: "We still don't get it."

    Steve Burke: "No problem. It's both enjoyable and profitable for me to cut your product open and show you a cross-section of what your own engineers designed, so you can't help but understand what your own engineers would have told you if you had asked them, when you instead just let the nepotism hires in Marketing dictate the idiotic photos you published to advertise your product, whose entire purpose is to improve physical performance."

    It's possible I'm attributing a little of my own perspective to Steve here. If so, I offer my apologies to Steve for projecting, but no apologies to the nepotism hires in Marketing.

    If the ideal front mount installation is with the hoses on the bottom why don't the AIO manufacturer's give you longer hoses? To be clear, I'm in total agreement with you. We want to front mount the radiator with the hoses at the bottom so the air can trickle to the top of the radiator and not enter the loop but then the GPU gets in the way and you don't have enough hose length to go around. I think the manufacturers need to give more hose length — especially on the 360+ MM AIO coolers but they seem to be penny pinching on that. For that reason alone, I won't buy an AIO. Even my 12900K I'm cooling on AIR (Noctual D15) and it's just as good as most of the AIO solutions out there — except in the most extreme benchmarks. But, honestly, who cares if I throttle when running Cinebech. 99.99999999% of people will never push their CPU to that point for any extended period of time in any real world scenario.

    Within 10 minutes of the video – empty verbiage and water from words. Maybe all the same, learn to speak clearly and concisely! And not like some kind of Italian – a lot of words, but little meaning !!!

    I'm installing a liquid cooler on a rack mounted PC. Meaning, the radiator will be in a horizontal position. Imagine a regular PC with a 360mm radiator on the front panel, but then laying horizontally on a table, and that's how my radiator will be positioned. How can I tell which tube in the radiator is pulling liquid and which one is pushing liquid? That's very important in this case, as one of the tubes will be at pump level and the other one much higher than the pump. The tube that receives liquid from the pump needs to be on the top, and the tube that pushes liquid into the pump needs to be at the bottom. I just can't find any information on how to make sure of that.

    what if i had pump in a radiator? how should i install it on front

  • Rafael de Arruda Campos Barato

    I have a Cooler Master Masterbox Q300L case and recently top-mounted a Cooler Master Masterliquid 240MM ML240L V2 water cooler.
    But before that I used to run my setup horizontally, with the case laid down on my table, glass top. It just fits better in my room.
    My question is, can I still use my case horizontally with the water cooler? If so, how?
    Thanks in advance. Cheers from Brazil.

    So this mean.. i can mount a aio cooler on front case with the tubes from down right?

  • DaBurntToaster

    November 5, 2022 - 3:24 pm

    this is why i dont understand why they use centrifugal pumps instead of positive displacement pumps, like a peristaltic pump, considering you dont really need all that much pressure im pretty sure you could fit one in some of the larger water blocks ive seen

    so if my air for cpu is on top tubes down, and my gpu is air too where I put gpu radiator?

    what about a aio unit in a HTPC where the Rad is sideways? like the new fitting in the silverstone cases Grandia 11?

    I just bought a system from NZXT and the tubes are still at the top. To make matters worse the tubes from the pump are on the right side of the CPU and prevents the installation of RAM in slot 1. Their support said rotate the pump, OK will I need to reapply paste? No, it won't be needed…
    I haven't started the repair so I don't know about the paste…

  • FAKENAMEFGUGLE

    wonder why no one ever has it sideways

    I can’t believe I haven’t learned this until today. Been building PCs for over a decade.

    Got a BIOS error this morning that my CPU temps had hit the junction maximum. Watched this video, see that my cooler is mounted improperly but don’t have time to fix it today so I’ve rotated my case to sit on its head and tilted 30Β°. CPU temps have dropped back to normal and a new cooler is on its way πŸ™‚

    This is a common sense for people who own fish tanks with a sump. The pump always need to be FULLY submerged in water, or else the pump will be damaged or gurgling noise and bubbles will be appear. Therefore, the pump needs to be at the lowest point in a loop.

    Why don't manufacturers have longer tubes, just 2-3 more inches so that they can accommodate large cases that are increasingly common? I hate short cables, short tubes… extra short is such a, shall we say, shortfall.

    does it matter how the pump is rotated? if the entry and exit with liquid is up, down, left or right?

    Hello. How should i mount my aio which has the pump on the radiator not the cold plate?

    TIL that my NZXT AIO has been mounted wrong for close to 7 years now. LOL

    this happened with my first aio i bought. ended up returning it immediately because it was way too loud, and i had it installed according to the pictures instead of how it was supposed to be
    still use an air cooler cause it left a bad taste in my mouth and i never bothered with aios after that experience

    Had a lot of issues last weekend with monitors losing signal, BSOD 10 sec after I log in but not in safe mode. DDU and got new GPU drivers but didn't work so had to reinstall OS in the end which fixed the issue but I at times had my monitors losing signal and having to restart pc. Took forever with many others coming with tips until I finally found out the reason, GPU fans were acting up… Ordered a new GPU and thus also a big tower since a 3090 wouldn't fit in my current one and for the first time actually did something myself with my pc hardware as I usually buy prebuilt.

    Well after watching this video I now also know why I sometimes hear my water cooling, the radiator was front mounted but with the tubes at the top, now I got it top mounted and 3 days without a single gurgle sound.

    CPU usage is very high though so hopefully I can get my hands on a 13900k soon after release and upgrade the rest as well, was worried about the thermal paste part but I guess air bubbles isn't actually something I need to be concerned about after all.

    So I planed that my first own build has two AiOs. One for CPU and one for GPU but that doesent seem to work if only the top mounting is save enough.

    the entire point of a PUMP is to pump the liquid through the radiator lol orientation doesn't damage it. Learn how pumps work you sweaty neckbeards

    What is wrong with the NXT manual? The pump is way below the radiator

    Helped even two years later with first AIO. thaks

  • darren elkins

    November 5, 2022 - 3:24 pm

    a pump should never be the highest point in any loop
    Also, Im curious as to why radiators might be front mounted anyway?
    The heat from the radiator is then pushed back across the motherboard and components.
    Surely a PC radiator should always be at the top or rear of a case if possible?

    or mounted inside your swimming pool…

    I wish my case and cooler allowed me to do anything other than mounted next to the cpu with the tubes at the top. I have a Thermaltake Core P3 and a Gamer Storm Captain 240 EX. Its worked great, but it was the only way i could mount it which sucks
