Hi danny889:
Totally agree with cheeseman.
Pop off that puny little fan and HS, take some very fine Sand paper and lap through the Thermal goop, NVidia Gforce label (round) and stop when the color just starts to turn coppery. Put on a real HS and at least a 21CFM fan, move all PCI cards as far away from the VidCard as you can, load the latest drivers which can be found here:
Detonator,
Then go and get PowerStrip, here:
PowerStrip2.65
I know you said you didn't want to modify it, and you've got the best of the litter for OCing SDR GeForce cards, but you'll get so much more out of the little beast with these simple tricks.
HS on the memory modules also helps considerably.
