Intake and Exhaust Fans

Should the side case fan near the CPU be intake or exahust?

Currently, I have 2 80mm fans. Intake at the bottom front and exhaust on the side near the CPU. Am I doing this wrong? I've been told that I am.

  1. Side? As in side panel? That should probably be intake.

    Mike.
  2. Intake

  4. Even if the side fan is right inline with the CPU, it's better for it to be intake? Then the fans will be blowing at each other.

    I think the best thing for me to do is just to test it both ways.

  5. Something is TERRIBLY wrong with your PC! Your fan on your CPU should be blowing down - towards your Motherboard. The side panel fan should also blow in so that the heat sink fan is blowing fresh air on to the Heat sink

    What are your CPU temps, because, from your post, you sound like you have it ALL backwards :eek:

  7. Ok, yeah. I've totally confused myself, and probably you guys aswell. The CPU fan is on correct, toward mobo.

    My CPU temp at idle is about 48 to 50.

    And I guess I'm getting the concept wrong about wanting to get the hot air out through the side. Guess I should be doing that out the back, and intake on the side.

    Maybe that's why my OCing isn't very successfull! :smile:

  9. That's high for idle, unless it's a Prescott, or overclock.

    What's your CPU?

  10. You already have two exhaust fans, you forgot about the one in the power supply. So you have 2 exhaust and 1 intake, now you'll have 2 of each.
