Fan direction?

[Fierce]

Now that I have built my new computer, I have found a couple of areas that I could install more fans. Question is, should I set the fan up to suck air out of the box or should I blow air into the box??? TIA!!

At the bottom front of your case, have a fan sucking air in. At the top rear, have one fan blowing out (besides the one in the power supply which is typically weak). If that isn't sufficient, then you can look at adding more fans. My first recommendation is a slot exhaust fan just below your video card. That helped my overheating problems considerably.

A lot of people go with the 'wind tunnel' plan, either pumping air in the bottom and out the top, or in the front and out the back (don't pump in the back, it's always warm back there). I just go with the plan of getting as much warm air out as possible (you know it works when you hear your soundcards ears pop :D ).
