  External Case Fan 
 Date Written 
Edward Saunders Sep 24, 2008, 09:46am EDT Report Abuse
I bought a new 1000w X-3 Ultra power supply, and it's much longer than my old PSU.

It covers the top cooling vent, where I had a 120mm exhaust fan drawing out air. Now this new PSU covers 3/4 of the vent and I can't get any size fan on there. There is 10mm of clearance between the top of the case and the top of the PSU, but a fan in there wouldn't work.

My question is this, I have been brainstorming all night trying to figure out a solution. Is there a way to mount my case fan on the outside of the case (I know you can, but it's ugly) to where it's still attractive on the outside? Also, I'm assuming that this top vent is worth having a fan on assuming heat rises, if not maybe I'm just wasting my time.

Thanks in advance.

I would just use the case without that fan.

1. The hot air will still rise, so some hot air will still escape.

2. If you do externaly mount the fan, it will be loud and over stressed, since 3/4 of the opening is covered by the new psu.

3. The new psu has fans in it already, so it wont be quite as efficient as it used to be, but should work adiquately.

Do you still have an exhaust fan possition available on your chassis just below your PSU?
If so, you can mount your fan there.
My present build IS ugly as hell, but it works with an external 3x120mm radiator and fan sitting on top of a couple of CD holders. I could make the effort of tapping the case, inserting some 2" standoffs and mounting the radiator to it, but hell, this thing doesn't move, and I'm the only one that has to look at the ugly thing, but it does its job.

Finished on the weekend in about 2 hours. Doesn't look bad... The only reason why there is tape by the bottom screw is because I did the screw not thinking that I still had to shut the case.:blush::P The fan is only a 250 watt 17.99 from tigerdirect. This computer use to run off a 180 watt power supply. If you have any questions about it send me a PM.
