Analyzing PC noise

Hey folks...I'm picking up some fan noise from my PC tower when I'm recording VO stuff. When I fire up Sound Forge 7 to start recording, the ambient noise never goes above -55db on the VU meter...

I've been gating everything below -55 with Sound Forge's Noise Gate, and then Normalizing to -6db when mastering the tracks, but I was wondering if there was a way I could point the mic at the computer and then drop the frequencies with an equalizer, or if I should just record into Cool Edit Pro and analyze the noise, then use the Noise Reduction function to get rid of it. And before anyone asks, I really can't move the mic's position relative to the tower.

Here's the equipment setup.
-Behringer B-2 Pro large diaphragm Mic
-Yamaha MG 10/2 Mixer
-A FMR RNC 1773 and Behringer Composer Pro XL chained via the I/O insert
-An Ensoniq DP/Pro on the mixer's Aux Send/Return for FX

I'm coming out of the mixer's Rec Out ports and into a Creative SB Audigy2 Platinum eX, and recording most stuff with Sound Forge, but can Cool Edit Pro if it ends up being the better choice.

Hope someone can offer some advice. I appreciate it in advance.

Best Regards,

if you can't move the mic then move the tower....
get a noisless cooling solution for your pc (power supply etc..)
the software you will be using will make no difference
another thing you can do to lower the noise is maybe just put a blanket or carpet to try and isolate the tower as most of the noise is high frequency it will be filtered
