I have a inwin 101 case. At the bottom you can have 3 fans. I have them set as intake. There is 1 fan on the back as exhaust. Instead of having fans in the front they allow you to place 2x120 fans on the side.. which direction should these 2 fans go?
If you keep bottom as intake, which is fine, then side and rear has to be exhaust as hot air goes up. Just make sure you have enough room for intake circulation beneath the case. Make sure there is some room beneath the case.
