My guess is about once every week. The display is on for roughly 16

least not that I could confirm. I haven't found a link to a specific
application either. This system is a general purpose workstation and it
is exposed to most common types of use. I design and create courseware,
which involves running virtual machines with libvirt, coding in several
languages, video editing, graphics editing, sound editing, editing all
kinds of documents, and the standard internet stuff. I haven't seen this
happening more often with any of these uses.
Thanks for the reply!
This blog post seems to indicate it might be due to the fan not turning
on enough at moderate load by default (it pulses off and on which is not
enough):

cat /sys/class/drm/card0/device/hwmon/hwmon0/temp1_input
Should give temperature:
Mine right now is:
29000
which apparently is 29C.
/sys/class/drm/card0/device/hwmon/hwmon0/pwm1
is the power management.
I'll play around tomorrow.
