Can an AIO replace case fans?

Recommended Posts

Posted · Original PosterOP

My PC case only has 3 fans, with no top exhaust. If i were to buy a 240mm AIO and front mount it, replacing my 2 front case fans and only leaving a single rear exhaust fan, would my PC get too warm? Or would this work?

It can replace case fans' job but at the cost of pulling in warmer air. CPU temps will be fine, GPU temps may go up a bit.

I ran a stress test for my GPU and it maxed at 75. Would having a front mount AIO be safe on it?

That's not significantly high, so you should be just fine. Arrange the fans in pull to avoid dust build up between the radiator fins and the fans.

Well, yes, but you could also rig it the other way around, AIO pushing air out and rear fan pushing air in. It depends on your system.

 

For example if your VRMs are getting overheated and you don't have a monoblock, you may want to push cold air over them instead of pushing hot air. 

 

The main idea with water cooling is to move the heat to the perimeter of the case and get rid of it, not to push it around the case and heat everything else inside :)
