The program is accurate, the sensor is correct - in this case it's the CPU's IHS sensor - it is reading at or just a hair below ambient temps. I'm pushing a lot of cooled air onto my cpu cooler and pretty much nothing else out of that little loop up there, but it works.
I'm not claiming that I have core temps at or below ambient, just the temp off the cpu's IHS. My cores are consistantly 15C higher than the CPU IHS value at idle and about 10C higher than the CPU IHS at load. The distance between the values goes down because the IHS gets hotter, faster under loads, obviously.
Someone mentioned using coretemp as a more accurate program to measure the temps. If they have a version out that doesn't require me to use an unsigned driver I'd be more than happy to give it a shot and snag a screenie... :shrug:
Simple science of the matter is that - for the "cpu temp" which is just off the IHS and is not the same as core temps, you can have a value lower than ambient. I have two 120mm fans 3" away from my TRUE pushing fresh air directly onto it. And on the TRUE there is another 120mm fan forcing that cool air across the fins and directly into the 120mm exhaust fan.
