I just recently purchased the CM Storm case which included 2 front intake case fans and 1 outtake fan located in the back. I have 2 additional fans coming in the mail and I am wondering where I should place these. I have 1 empty slot on the bottom, 2 empty slots on the side and 2 empty slots on the top.

Thanks

If the diameter of the new fans is compatible I would either install both fans on the top or one on the bootom and one on the top. Why? Simple physics. Hot air goes up. What you want to do is to force the hot air outside your case. There are little arrows on the fans that show the air flow and you can easily put them as they must be put.

I would go one bottom and one top, to get new air pulled into the bottom, ran through components, then pulled out the top. You could put both on top, but then you're just expelling lots of air and relying on negative pressure to move new air in, i like to forcibly move air in with intake fans, and move it through fast so there's never too much hot air in the case. No as for positive vs negative pressure, that's a totally different debate
