Windows 7: Help with fans.

I totally agree with the above post, but want to add that if you don't put a fan in both of the side or top positions, you should fully cover the unused fan opening. If you don't, you risk the adjacent fan pulling or pushing the air from the closest opening causing a 'short circuit' and having no net effect on cooling.

The side fans are optional, but if you fit them they should be pulling air into the case. If you do fit them, you should also fit the top fans and have them exhausting air from the case.

Just one more little hint in passing...

If you wet your palm and hold it about an inch from your mouth and suck air in as hard as you can... what do you feel? Not much, eh?

Now repeat this execpt this time blow air out as gently as you possibly can... Oh WOW did you feel that?

Well... heatsinks and components react in pretty much the same way.

When thinking about case cooling, always think about how to get the most cool air into the hottest spots and how to get the resulting hot air out of the case, in the most efficient manner possible.
