keep in mind 70 may seem hot

but this chip will handle it, that was some of the reasoning in intel lowering the power usage, so people could spin down HSF on the quad, it would run hotter, but not be noisy, the 100c tj has alot do with that.

so if mine peaks out at 70c load. i wont be worried. its within spec.

and one could enable EIST to throttle down the cpu, to prolong the proc. I have eist and speedstep enabled on my 6600 and it runs fine at 3.6.
