I suggest you see my "guide" that I linked in my sig about convection and thermodynamics.
That fan isn't going to be moving much air so what air it does move is going to be hot. You want hot air pumped into your system? No thanks. You're much better off drawing cooler air in from the bottom and pumping hot air out as soon as you can. Also what's the air already been heated by? Nothing is in the path from the bottom the the case.
For example, GPU stock coolers, if the coolers just blew all the hot air in to your case, you would rapidly end up with a hot case. Not cool.
And by the way, I'm very aware of convection and thermodynamics.
I was using an Antec Kuhler 920 which I had been given for testing. I was using an Antec SOLO II case. The front low speed fan was intaking cool air over my 5 hard drives. My SuperFlower PSU doesn't start it's fan until it's really hot so little air movement there. With my CPU overclocked to 4.3GHz, the 920 pumps out some really warm air with the fans on the silent setting.
About 10 minutes into some gaming my GPU fan is really going because it's intaking mostly hot air and the PSU fan is running. I realise the issue and swap the radiator fans.
After the fix, the PSU fan never came on and the GPU stayed cool and quiet, as it should be.
I have no idea why you would ever say that radiators should be mounted as intakes. Any heat produced should be exhausted out of the case so the inside of the case stays cool. This is why everyone loves reference coolers that exhaust heat out of your case, it just makes sense.
You're nuts.Edited by Willhemmens - 6/27/12 at 10:03am
