Side vents: intake or exhaust?

    Hi all,
    Anyone have data on whether it's better to use a side vent for intake or
    exhaust? Either way seems to introduce turbulence to air flow in general,
    I'm just wondering what most folks are doing and find what works best.

    Thanks.

    On my three systems, the side fans/vents are intakes. The PSU an
    rear fans exhaust, and the front and side fans take air in.

    The CoolerMaster C5 case I have comes with a side-mounted fan funne
    to channel air to the CPU, and the entire front is mesh with a foa
    filter behind it. This vent does not have a separate fan, just th
    vent going to the CPU heatsink/fan. The funnel improves flow

    I believe that the case should have equal numbers of fans blowing i
    and out to optimize airflow. I am sure there are other factors, an
    I have intake fans powerful enough to hold a sheet of paper in place

    If you're feeling really warm, do you sit in front of the fan - or
    behind it?

    In other words, you can direct the flow of blow - but not of suck.
    (Unless you work in a specific industry.)

    Most cases have sufficient gaps in their construction to allow for
    dissipation of heat into the local atmosphere. If you have considerable
    air movement in, it has to be matched by air movement going out.

    Concentrate on cooling the bits that need it the most. Heat extraction
    will generally take care of itself.

    I don't believe that *any* case needs extractor fans over and above what
    the PSU achieves. (Given that the PSU tends to be situated at the top
    of the case.)

    Aluminum or steel case makes negligible difference in cooling.

    Bullshit. Steels cases are just the same. Though i prefere lighter.

    Ive got a 120mm Fan blowing in on the side. Cut the hole myself i did
    :)

    Ive got a 120mm fan exausting air at the top of the case :)

    And 2 80mm fans at the back + the Powersupply fan. I need some air
    blowing in via the fron 120mmfan and side fan.

    Or do you disagree ?

    1708 CFM HOLY CRAP. that many fans, thats a cut and paste job right
    !!!

    No one in their right mind would put that many fans in a pc case ???

    Bloddy PYSCOS :p

    My AMD64 3500+ is in a steel case and its idle temp is 36c. Many tests
    have been done to show that steel vs aluminum case makes little
    difference. You must be using crap steel cases or something.

    Read the article I posted and decide for yourself. IMO, you don't need
    a fan blowing in, or two 80mm fans at the back, one will suffice as
    you have the top 120mm fan already.

    Yea, I take it with a very big pinch of salt. There are tech sites
    that have tested alu compared to steel and their conclusion is that
    there is a negligible difference. One thing going for steel though is
    that if you are aiming for a quiet PC steel is clearly superior as a
    soundproofing material.

    OK, I work from experience too and I currently use just one rear 120mm
    fan. Look up Intel's and AMD's recommendations, you will see they
    recommend exactly what I use. Too mnay fans just creates turbulence
    and makes the hot air in the case circualte inside the case. And that
    article tested many configurations. How many have YOU tested? :-\

    I don't care how many you've built, you still don't know how to
    install an efficient cooling method. Yea, I see people bragging about
    how they've got six case fans and I just think they are fools.
