Question about Intel dual core (E7500)

[AKH775]

Is it common for one core to run hotter than the other? Speedfan tells me that Core 0 is at 42 degrees, Core 1 at 51, with nothing buy Firefox, Speedfan, and Outlook Express running. I've never seen Core 1 cooler than that temp.

FWIW, heatsink is a Cooler Master Hyper 212, thermal compound is Antec Formula 5 Silver.

Yes, It is normal.
My Core i7's cores run at different temps.

Yes, especially if there is a mix of processes that can only use one core and those which can be balanced between two cores.

Run Prime95. That will load both cores to 100%. Run it 15 minutes. That's long enough to drive core temps to their max values.

I might be mistaken, but I was under the impression that the wolfdale core 2s only had 1 temperature sensor for the overall temp. I might be imagining this though... I have 2 e7500's systems and mine usually reads both core temps at 39 degrees no matter if one is loaded and one is idle.

But I could be mistaken.
