    I have decided to install a 12cm case fan in my new 2.93Mhz Pentium 2 Duo with Gigabyte GA-EG41MF-US2H motherboard PC.
    I have noticed that while the CPU doesn't get very warm the heat sink on the G41 Intel chip on the motherboard gets quite warm (is this normal?).

    Is there a preferred direction for the fan to blow the air - blow the air INTO the case or blow the air OUT of the case?

    I guess the thermal change isn't much different but what about dust getting into the case?

    Thanks

    Hi, on mine they are extracting the hot air, then it draws cold air into the case which is not being drawn over the fan motor.
    Cheers des.

    Thanks for the quick reply.

    It's a pity that case manufacturers don't make sealed cases (apart from where case fans are installed) so that you can add an air filter (such as on an air conditioner) as it's incredible how much dust gets inside which can cause problems.

    A number of the upmarket cases have an inlet air filter - fine gauze. My Antec Sonata does and stays clean internally over long periods - I guess I dedust annually.

    Clearly a need to balance the degree of filtration with the power of the fan - case fans really only shift air rather than pump air. Fine filtration would require a powerful - and noisy, volt hungry fan which would drown out all other noise and be a constant irritant :)

    Most effective cooling is air drawn in the front and exhausted out of the back as demon posted.

    I've marked this thread as 'Resolved', please see .....
