Correct Air Flow With AIO CPU Cooler

[Nortski]

I'm a little confused which is the best way to install my Cryorig A80 AIO cpu cooler.

According to the instructions, the fans go on the inside of the rad and push the air through it. But doesn't that mean the fans will be pushing the hot air from inside the case through the rad?

As hot air rises, my plan was to install this at the front of the case with the fans pulling cold air from outside of the case while the two 140mm fans on the top of the case push the hot air out through the top.

Can someone please explain the correct way to do this?

It won't really make much of a difference. Go for whatever is easiest and looks the best.
I have mine in the roof, simply because I can't install it on the front, but other than that I think it looks better

It all depends on your GPU and case ventilation.
If you have an aftermarked cooled GPU, i would put it in the front.
If you have a blowerstyle GPU i would put it in the top/back.

This can put some light on your problem.

Ah that's great guys, thanks for the replies.

Gonna put the kettle on and check out that video

If mounting at the front aim to have the hoses at the bottom to avoid any air being circulated.

Thanks for the tip

Really?... Although that would look very silly if you ask me ^_^

It would look daft but the idea is the air gets trapped in the top end tank.

AIO's are fairly good when it comes to being fully filled normally though so it shouldnt matter. If I constantly heard air in my AIO Id return it tbh

Agreed but not an issue if no window

How can you tell? I have AIO and do not think it is as good as it should be

Ahh I see... Is it the same case if the AIO would be horisontal? Ie like in the Corsair 380T or 250D, for example?.

There is always a little air in AIO systems. There is a little air in water cooled systems. It makes a wooosh sound when there is a lot of it. Coolant also evaporates over time.

Bubbling noises. The pump can sound like it's grinding almost.

Oh so the reason AIOs are suppose to be hoses in the bottom is for the tank to "stand in" as a RES??? And it does not matter in custom watercooling?

I'm preparing a custom loop in my 250D, and it would be easier with in/out in the top of the front radiator But the install guide from my 1070 hybrid had me thinking that they always should be in the bottom

 

[Avet]

In custom loop cooling it is easier to bleed the system. That is the one of the functions of reservoirs. Air gets trapped in the res so you can open it a fill it a little more. Even if you are sure you tilted your case enough and got all the air out, after few days/weeks you will see fluid level in res to go down, because some trapped air got out and ended up in res. AIO coolers don't have reservoirs, and the air constantly circulates the system. There are fill ports on some AIO coolers that you can use to refill them like Kelvin, Eisbaer but it is pain.

 

[Korreborg]

So? There is no problem in having a rad with in/out in the top?

None at all. You just need to bleed the system well when doing custom loop.
