    here are my temps:

    46 HD
    39 CPU A
    63 Diode
    60 Heatsink
    19 Ambient
    57 memory controller
    74 northbridge

    and my fans haven't changed their RPM since ive unboxed it.

    997 Optical
    1100 HD
    998 CPU Fan

    I've already tried an SMC fan reset. What gives?

    My temps are higher and the fans still stay around the same speed.

    but, are they just sitting at the low rpm of 998, 1098, 998 as well? when you say same speed what do you mean?

    Those temperatures are fine( though I don't know the normal temperature for the northbridge as the i7 lacks it) and those are normal fan speeds for normal use. My fan speeds won't change until the CPU hits 70 C.
