    cpu fan/heatsink cooling question

    im going to be building a computer soon. if u have a cpu cooler with a side fan
    instead of on top of heatsink, which direction should the fan be facing down or
    facing the rear of case or what? its going to be used on a 5000+ BE.
    i found a couple of heatsink/fans from www.frozencpu.com which is best to use
    and for a good price and mabe a good website to order from. $45 would be as high as i would go for one.

    for just a few $ more you could get an ultra 120extreme about 52 shipped or so on sale.

    as for op most blow front to back to push the air out of the case to the back vent fan.

    It should go with the case flow, so RJ_Hythloday is pretty much there: fit the cooler with the fan blowing air through the fins from front to back. If you have a case with a blowhole, and the cooler allows it, you can also mount the fan so that it blows air upwards through the cooler. But don't do this unless there is a blowhole.

    Sometimes you are limited to the direction(s) of the socket. Up is prefered to down, back is prefered to forward. As stated without a blow hole back is prefered if you have a choice, and the blow hole should have a fan appx the same cfm as the cpu fan, which could get noisy.
