    What are you guys getting for your CPU temps?

    For mine when I load it up in Prime95, it shoots past 85c. Idle temps are around 47-55c. Processor is an i5-2520. The fan seems to stay on a lot more often than my old T400.

    Is this normal with other T420's or could there be a heatsink/thermal paste issue?

    My core i7 averages at 41-43 C with moderate use (HWiNFO32). Got a max of 48 C. Haven't put it through a stress test though. The fan is either off or at its lowest most of the time. It was audible a few times but just for a brief amount of time. The room temperature is ~75 F.

    When idle my T420 (Core I7-2620m) stays around 40 degrees celcius, but when I'm converting raw files or/and music files I've seen it reach 92 degrees. Usually when surfing or writing my fan is off.

    Mine idling around 37c, though I have a Core i5 2410M processor instead. Haven't really stressed mine yet, though I do notice the temps are on par with my T61 Core 2 Duo T9300 which is good considering the performance difference.
