Which direction should the CPU fan blow the hot air?

Is it good for my CPU fan to blow the hot air toward the PSU?

Here is the photo of the inside of the computer: http://s299.photobucket.com/albums/mm317/cerbere1564/?a...

If I turn it the other way, it would be blowing the hot air toward the video card.

Is it ok the way it is set up?

normally the hot air would blow up or back.

And I also think it's about time you upgrade that rear case fan!

I think you should lose the rear fan as it is dosturbing the airflow inside your case. Make sure the CPU blows towards the PSU.

^NO, NOT to the PSU, that's the old way with cheap cr@ppy cases! It should blow to the rear fan. And the rear fan should be an exhaust fan, like said above probably should get a quiet 120mm fan like a Yate Loon or Scthe.

@OP: What is that case? It looks pretty cramped.

The case is a RAIDMAX Tordano (Not great at all), and I cannot get the CPU fan to blow toward the back as it is too wide...

+1 mi1ez. I would upgrade that 80mm fan with a nice 120mm fan. I looks like your case is setup to handle a bigger rear fan.

I have the same CPU cooler and the directions show for the fan to below the air out of the back of the case. Looking at your picture the cooler should be rotated counter clockwise. I had this cooler in a Thermaltake M9, which was a very tight fit between the PSU and cooler but I was able to make it work (millimeters away from the PSU).
