    Should I switch around which way some of my fans blow? My PC only has two real exhaust fans, the two on the top. Everything else, the front, rear, and side, are all intake. So 4 intake fans and 2 exhaust. Should I switch them?

    How many on each side? If you have 3 front, 2 top and 1 back, I´d make the back an exhaust to create a wind tunnel.

    You could flip the rear one. Otherwise you likely won't notice much of a difference.

    There are 2 intake on the front, one intake on the left side, one intake on the rear, and 2 exhaust on the top.

    I'll probably flip the rear one next time I have the PC apart to dust it out.

    The side huh? Wouldn't know what to do with that one. Switch the rear one and you'll be good to go.

    Rear and top should be exhaust, front and side should be intake. As the saying goes, heat rises.

    Yeah agreed with John. If you have more intakes than exhausts you reduce dust (positive pressure) with lower performance. Conversely, more exhaust with less intake is better cooling but more dust (negative pressure).

    Current setup now:
    2x 120mm intake front, 1x 120mm intake left side, 2x 120mm exhaust top, 1x 120mm exhaust rear.

    Future plans:
    1x 200mm intake front, 1x 140mm intake left side, 1x 200mm exhaust top, and 1x 120mm exhaust rear.
