Gpu randomly cooled itself

[zetyorant]

I was doing a stability test whit
AIDA64 Extreme.
It was all good for an hour when randomly my gpu temp went from 67 to 42 in less than 1 minutes.
What happened?

Pc rebooting while playing lo and/or recording,could this be the cause?

Did fans ramp up? Do you see any indication of thermal throttling? (not likely at those temps).

Entirely possible the specific portion of the stress wasn't GPU intensive - not 100% sure with AIDA, honestly.
