Maybe better thermal in early 2013...

    So I have an early 2013 2.7/16/512 and refurb 2.6/8/512 currently...

    Running Cinebench on both after resetting SMC on both and having nothing else open...Ran the OpenGL and CPU on one machine and then on the other - back and forth three times observing highest fan speed and temp (SMC fan control / right fan)

    Early 2013 2.7 OpenGL / CPU - 39.03 / 6.94 - 6.98

    OpenGL: 81-82 degrees w/ fan speed ~2000rpm
    CPU: 101-102 degrees w/ fan speed 3015 - 3043rpm

    mid-2012 refurb 2.6 OpenGL / CPU - 37.83 / 6.55

    OpenGL: 85-87 degrees w/ fan speed ~2000rpm
    CPU: 103-104 degrees w/ fan speed 3975 - 4058

    Fan definitely came on earlier and obviously spun up faster in the 2.6 than the 2.7 in the CPU test.

    This is all anecdotal, so take it for what it's worth...

    First thing I did was replace the thermal paste on mine when I got it. Haven't noticed it getting excessively hot since?

    It's certainly much cooler than my mid 2010!

    It's probably a combination of better performing Ivy Bridge parts + internal upgrades. Your temperatures are significantly lower on the 2013.

    There's also a change to how the chiclet keys attach to the keyboard...Had to raise a couple of keys on the new one, but compared a few keys to the refurb one, and can see the white piece underneath the key that holds the black letter part is different and you cannot interchange chiclets from the mid 2012 to the early 2013.
