Exhaust fan suggestions

  1. I'm planning to put a computer in my entertainment center. The system will be located in a space that measures about 45in x 22in x 20in (1143mm x 559mm x 508mm). The PC will sit next to an amp that already keeps the area pretty toasty. I would prefer to vent the area rather than having to keep a door open all of the time. I'm considering purchasing a 120mm 68.9cfm@30db computer fan w/fan guard to blow air out of the entertainment center into a space that is open to the attic. The fan w/guard is around $22. Does anyone have any suggestions or recommendations?

    Here's my Cooling Resources:

    You might also try a homewares store (HomeDepot, Lowes) for 3" ductwork, sheetmetal or flexable (bathroom exhaust fan stuff)

    I'd mount a fan & filter intake, then exhaust rear to ductwork. Depending where you room is located, you might vent into an uninsulated wall, especially if it's a closet wall void or plumbing void.

    The fan that I was thinking of buying is a 120mm Panaflo. I'm planning to power it directly using an external power source. The fan will be mounted to a "wall" consisting of 1/2" drywall with 1/2" plywood behind it. I'm planning to screw the fan to the plywood through the drywall.
    I like some of the accessories such as the fan ducts that PCMods has. A duct should provide some noise reduction and give the hole a finished look. I think I'm going to go with the high output fan rather than the 68.9cfm though. Thanks for the links guys!

    If you are venting the fan to an outside or non-living area, you should consider a bug/bird screen to keep the "creatures" out.
    this would slow down air flow from a axial (blade) type fan.
    since you are considering a duct anyway, you could place amore powerful fan (squirel cage type)in the attic, sucking the air out.

    Cooling fans

    I use a YS Tech fan to cool my SuperMicro case and it moves like 40 CFM of air. At only 60x60 its very small yet very powerful. It is a bit noisy but man it moves the air.

    Take care
