Where should I put my second fan?

[iamfried]

I just bought a new case and it has one fan that blows from the side of the case right onto the mb. I have another fan and want to know if I should put it on the front or on the back. Also, on the back would be blow out of case and on the front would be a suck into case, correct?

If it has a spot next to the cpu, try there.

It varies depending on the case but I find the a front (92mm) cools down the case by at least 5'C when under load.

The slot cooler only cools by an extra 2-3'C over the front fan (don't get a slot fan, not worth it).

I should imagine that a fan above the power supply would also help in case air flow.


When it comes down to it, it is a case of what you think works best, I have see so many review which tell you one way, to have anouther tell you different.

Ok, thanks for your reply. I the one on the side is right over the cpu. The one on the back is just to the left of the cpu so the two fans would be all of about 3 inches apart so I don't think that will work.
But do I want more fans blowing in than blowing out, or does that even matter?

It's usually better to have more blowing out (exhaust). That way you have more, cooler air circulating into the case instead of stagnant hot air in the case.
