    Been using m14x for a week now and i notice something. is that core #2 have a significant lower temperature compare to core #0 #1 and #3. just wondering if any of yours have the similar behaviour. i've check the process load they perform the same so it's not like #2 is "lazier" but what could've cause this..

    intel just spliting up work load core three may be assigned less intensive things on each thread. Thermal compound differences across the chip.

    Yeah it's just the drivers splitting up the work between the cores. Don't be worried at all, unless suddenly core 1 is 60 and core 2 is 5.

    Then you may have a slight problem

    hmm but the wierd thing is.. always #2.. thats why it got me concern..

    "Thermal compound differences across the chip" that was one of my thoughts too.. so wonder if those of you reapply thermal paste got a more consistant heat distribution...

    Core 2 might be dedicated to something not as intensive? Im not very good at what processors really take care of (I mean I know they run EVERYTHING but you know). My guess is that may just be the OS? The others might be for games and programs.

    Intel uses temperature sensors that are only accurate to within +/- 5C. Any variation from core to core that is within that range is completely normal and doesn't mean anything.

    I used to have ~70 on core 0-1 and ~30 on core 2-3, it happened when I was converting a large amount of files into rar. It stayed that way even after the conversion were done and a reboot fixed it.

    Sorry, I'm a complete moron. Why's there a difference at all...seems like they'd be close enough together that it wouldn't make a difference?
