Hey, I've got an e8400 with the stock heatsink, which I removed the thermal pad and applied AS5. It's all brand new, a few days old, so it's definitely not past the "break-in" if that makes a difference. HWMonitor shows one core running as 34c and the other as 38c at idle. Is this difference between the two normal? I'm wondering if the heatsink is mounted properly. I did make sure that all four tabs were all the way through, but you know how that goes. I don't intend to do much for overclocking, obviously with the stock, but I might try to bump up to 3.6ghz. Thanks for any help.

Yes, up to 10C between cores is acceptable under load. All depends on the IHS when it was assembled in the chip.
Load the chip up and check again, sounds fine to me.
Thank you. I ran 3dmark2006 and both cores evened out at 49c.
