I read that my VGA can be pulling 200W at idle in Vista with Aero enabled so if the CPU is pulling over 200W during Small FFT's, that is over 400W that this MCR-220 is trying to dissipate so clearly that is causing the high temps.

Thanks for all the input and advice everyone
Hey Rich, is your rad really hot to the touch? For those temps I would expect a very warm rad at the least. If it's not warm, you might be getting some issues with contact and/or flow.
