Hello,
If I have two 120mm fans both with CFM stated at 80 each.
Does installing the two 120s side by side on the case side total a CFM of 160 or is it not that simple?
I'm wondering whether to go for a large side fan such as a 200 or 250mm or multiple 120s.
Also, balance of air being pulled in and air being pulled out. Should this match? The case I'm looking at is an old thing I picked up for £5. Currently has accomodates 80mm on front and on 80mm on back. Would like to change these two to 120mms then put something large on the side as my AMD dual 3Ghz really heats up every board it sits in. Should a a 4th fan be added to compensate for what the 3rd fan is doing?
