When you install case fan in the case, to get a better air flow, air is going in at the front and out at the back. Then, how about the side fan? Air in or air out?
I just got my new case with a 25 cm fan on side blowing in. Its taken almost 10C of off my normal CPU temp and my system temp used to get around 42 C its now sitting at 29 C so having it blowing in is good - bigger the fan the better
