[gentoo-user] Dell Precision Workstation Overheating

[R0b0t1]

I was compiling Gentoo, as is custom, but found my old new server to
be thermal cycling wildly. The fans will turn on full blast and
machine check errors will be generated if I use approximately more
than one third to half of the cores. The cores then throttle
themselves, only to immediately overheat once the throttle lifts. This
seems to persist on Windows, though Windows seems to be much more
conservative in its CPU usage, and triggers MCEs less.

Any suggestions? I repasted the CPU and heatsink interface, and the
machine is not loaded with dust. It was hardly ever used. The MCEs
seem to be a "normal" part of operation, though less normal on
Windows.

Is there a way to at least mimic the conservative CPU usage that
Windows exhibits?

Cheers,
