I believe that the MCR-220 is good to dissipate upto 250 to 300W and if Everest is correct, the CPU is throwing out over 220W and when you add the HD4870 which apparently throws out over 100W at stock, you can see that the problem was obvious but I didn't see it until Hoss331 pointed it out.

I was actually going to add NB/SB and perhaps also Mosfet blocks to the same loop until I read the replies I got here

The fans in use are the stock ones which came with the MCR-220 as I got it as part of a Swiftech WC kit nearly 3 years back so each fan is capable of 75CFM each.

Thanks for all the tips and input which is very useful and will help alot. I am planning an overhaul as we speak and once temps are under control, I'll be sure to get the Q9650 higher
I've switched out the 2 x 75CFM fans for a 1 x 120CFM and 1 x 100CFM (didn't have matching fans ) just to see what difference it made, and it took SmallFFT load temps down about 4 to 5 degrees celsius so now, after 10 mins of running, Core 1 & 2 have hit a maximum of 69 degrees and Core 3 & 4 have hit a maximum of 72 degrees celsius which though a lot better than the over 80 - 85 degrees celsius I was getting a day or two back, isn't yet good enough.

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
