The CNPS9500 needs lapping???
I put that on last night. my E6600 is running right now at 3.4ghz. I'll reboot in a little while and post the voltage and temp (btw what do you guys use to measure temps in windows?)
The HSF is cool to the touch though. I'll admit though. It's in a Lian Li PC-V1200Bplus II Case with a pair of low RPM 120mm fans in the front and another in the back. The zalman (running at full speed) is pointing so that the fan faces the front of the case and pulls from that direction blowing it through the cooler striaght at the exhaust fan. Pretty effecient IMO.
