I have a 80mm fan on the side and on top of my case, a 120mm fan in the back, and a fan for the PSU. What should the proper intake/exhaust setup be? I've been trying to lower the temperature in my Aspire case but don't know how to. Exactly how do you determine if the fan is intake or exhaust? Is it just the direction you put it in? I noticed that one side the logo of the fan spins while the other side's logo doesn't move while in operation. Does that mean anything? Sorry for the amount of questions. I just want to try cooling my system down. It was up to 95 degreesF earlier today.
