Yes sorry, I am talking about CPU temps.
I'm not sure what settings in the bios are the power saving settings, do you know what they're normally called?
The thermal paste and fan installation has been re-done and checked a couple of times - all is good.
The fan is spinning just as it was before, tried it with and without the fan controller (i.e. from the mobo and from the fan controller)
it's an X2 5000+ CPU with an Arctic Cooling Freezer 7 Pro rev 2 cooler. I've OC'd it to only 3.0Ghz (it can get to 3.2) and at Idle i'm seeing around 40 Degrees...but on my old mobo I was seeing 33ish.
