Well I'm in a small room and have a 17" CRT that kicks out a lot of heat, this room DOES get warm quickly if I have the door closed and the curtains drawn at night, even with the window open. When the AF64 arrives I'll hang one of those sensors near the middle of the case and one near/touching the CPU and see what the readings are! I don't think It's wise to try and trap the sensor between heatsink and cpu though! Vcore is showing 1.33v, so that's right!
Already installed the Dual Core Optimizer and enabled Cool n Quiet, although the Processor driver is showing 1.3.2.0 and there is a 1.3.2.16, so installed that but it's still showing the same version in device manager after a reboot?
One thing I have done is use the EPP of the RAM to set it to performance in BIOS, this changes the timings to 4-4-4-12 and increases the DDR voltage from 1.8v to 2.38v and DIMM VTT from 0.9v to 1.18v according to PC Probe and Everest. although I can't explain why it's showing CPU Hypertransport at 1.39v when it should be 1.20v, not overclocked the CPU unless it's tied in with the SLI memory? Those are the only 3 voltages showing RED in PC Probe.
Installed the Power Monitor, why does everything need a sodding reboot

, but just shows the power as 1 red bar on the graph for each core! I turn all power saving options off in XP, always have and Vcore is showing 1.3v so that ties with PC Probe and Everest. Installed Dashboard too, jeeeesus another sodding reboot



, but I think it's broke, CPU is showing 40°C no matter what I do and the fan speed is always showing MIN!!
Ripped the tissue off the inside of the case front and system is now idling at 42°C for CPU and 39°C for system. When I've fitted the AF64 I'll try using front fan and 1 exhaust and then front fan and 2 exhaust and see which works best, no side fans! Then I'll see if 1 side fan exhausting or 2 exhausting affects temps as well.
