Raja I will get some Ceramique & give that a go on the weekend along with ensuring the heatsink is flat.

The rig is running Orthos small fft's at the moment (2 1/2 hours so far) at 462.5 x 8 3.7GHz with a 70mm fan on the PWM heatsink & a 120mm blowing down between the CPU & NB toward the long chips in front of the PWM heatsink. The heatsink temp is mid 20's & the long chips are low 30's.

One thing I now notice is Smartguardian is running very close to Coretemp (high 60's low 70's) maybe its the fans maybe its the later 521 BIOS I will investigate later & post my findings.

Regards

Craig.
