I have my e6400 oc'ed to 3.1ghz stable with 1.425v in bios, 1.37ish showing on asus probe. The weird thing is, coretemp shows my idle to be 23c, asus probe and TAT show 35c. Why oh why must you tease me coretemp!

Actually, neither temp is incorrect; they're just measuring two different temps, from two different places. iTAT and CoreTemp are measuring the temp from inside the cpu, as reported by the cpu itself. Asus probe is showing the temp from underneath the cpu, as reported by the motherboard.

The possibility that the case temp is near 23c is low, so no cpu reading should be that low. The temp differences are due to the way temps are measured within the CPU and your motherboard (or coretemp) misinterpreting the readings. I'm guessing that Asus probe is reading the on-die sensor that is between the cores, and core temp is reading the cores (incorrectly). They should be pretty close readings.

Easy fix: use Speedfan 4.32 and change the offset (i.e. add ~12c) to make it read correctly (if required).
