mcelog: Please check your system cooling.

[Chris Murphy]

This seems bogus but I can't really tell, and it hasn't gotten the attention of any kernel developers yet.

Like I mention in comment 7, I get:

[  900.693256] f20c.localdomain mcelog[581]: Processor 1 heated above trip temperature. Throttling enabled.
[…]
[  900.704776] f20c.localdomain mcelog[581]: Processor 1 below trip temperature. Throttling disabled

So in about 1/100ths of a second the temperature is too hot, and then OK, which doesn't seem possible if the times are correct.

This logging constantly happens anytime the system is even moderately used, it gets hot, fans are like hair dryers, but no other anomalies. It takes significantly more aggressive tasks to get OS X this hot. I'd say 1 out of 3 boots, merely boot+startup to gnome-shell makes the system hot enough to kick the fans to full and report these mcelog messages.

The claim of hardware error seems like a real problem, but I'm not finding any way to manually throttle or limit the CPU top end to prevent these errors.
