What is the purpose of water cooling AIO?

[animatiV]

AIO cooling blocks the possibility of inserting fans into the computer case, which means that the temperature in the computer case and GPU is higher.
I think it is a better idea to install the air cooling on the processor and additional fans in the computer casing.
I think well?

I know that water cooling aio have a larger FCM than air-cooled but they do not have a positive effect on the GPU temperature.

They don't block anything! They have fans. So they're like having fans in your case - but with a radiator for cooling. They're very good and efficient water cooling solutions for people who don't want to invest the time or money in creating customer loops. It's what I use in my computer IRL.

I just wanted to add a moment that using fans on both sides of the radiator gives you "normal airflow" through a radiator as if it wasn't there. But in PCBS we only get fans on one side of a radiator and can't add more and that (usually) will actually act like a blockage. You do get -some- airflow through a radiator with just fans on one side but it's only about like 20%, even if the fans are cranked to max. Really need the other set on the other side to help pull it through. And we just don't get that in PCBS currently.

If you get that little airflow, the radiator would not work properly. Check the net for tests using.. there's virtually no temp differences. There's usually >2C dif in a push/pull system and a normal set up. It's why few companies sell radiators that way.

No there's no difference in tempatures in the actual radiator it's self in push-pull vs just fans on one side. But the big difference is the other parts in the computer and how much airflow you can get -THROUGH- the radiator and in to the computer case to cool the other components.

Ohh, I'm sorry, I understand you. That I can believe, tho I've never had any heat issues peronsally. I don't overclock IRL or anything either for the most part. My system never gets warm enough for the fans to go above idle ^^

No difference and then difference?

And if you have a bigger difference between inflowing and outflowing air, some of the air gets sucked / blowed through other openings in the case, a computer case is not airtight.

Thank you for that information. I had no idea that computer cases were not air tight. All these years building computers for thousands of people and I assumed all this time that computer cases were completely airtight.

Higher airflow -> more air which can take away the heat -> lower temperature difference between air and coolant. Ok, we speak about around 2-3 K. But you say "no difference" in temperature of coolant.

Computerbase (Germany) did run a test and they got around 3 K difference with radiator at the top of the case, they used air which is "pre-heated" from the hardware. So the system doesn't get really hotter if you push only.

And you should show me a radiator which blocks 80 % of the airfow if you push only, maybe you're telling about a 60 mm thick radiator with high density (optimised for fans with higher static pressure) and you use silent fans at 500/min and low static pressure.

Yea.. I just did some research online and push/pull configs make virtually no difference. Certainly not worth the space/noise.

Just as a quick test I put 3 fans into the top of my computer case alongside my 360mm radiator and you can feel a bit of air flow difference, but it's not great. I have no doubt that radiators would block some air, but it appears to be less than significant in most situations.

So back to the OP's question: They do not significantly block air and are exceptionally good at keeping your CPU cool. If you want to be safe, you should probably have at least one other fan pushing air out the back of your case - that's a common set up for most folks anyway.

Here you go, actual test data:

It does matter and some day I really hope they both allow us to add more fans to each radiator in-game and to allow us to swap out / replace those fans. Maybe then we might actually get custom water loops in PCBS to be better than AIO's.
