Hi I am in a bit of dilema here. I am rethinking my air flow and I need some suggestions. Here are two pics and if you can please tell me what you yield the best results. The fans are in the PSU so that is why I am asking. It is going to take a long time to test them in each direction. So if you can tell me from you experiences which setup would be best that would be great.

First

Second

P.S. Sorry for the bad images. I only know how to use Paint.

EDIT: I am using an SLK 800 heatsink.
 
Of the two the second is going to be better because the first one will allow hot air from the PSU to blow over the CPU. Also test the CPU fan to see which way is better, sucking or blowing depends on the system, although generally blowing seems to work best.

I've already tested blowing. It was making this strange air sound and my temps were higher as well. I will do it again just to make sure. Thanks!
 
I remember hearing somewhere that a 'vaccum' effect would be good. Basically have more suction as opposed to blowing air in. So basically number 2 would probably be better. And having CPU fan sucking air? From my experience with air cooling, I thought blowing air out is the way to go?
 
Generally i think when someone says blowing it means blowing air on to the CPU. Sucking means sucking the air off the heatsink.

Ya?
