Today I stress tested this new patch a little. At first galnce
everything works well. If the cpu heats over 51°C the fan switches on
(6700), reaching 59°C switches to 8700. If the cpu cools down again the
fan switches to 6700 at 55°C and of at 48°C.
Interesting enough, when I have my endless loops run longer the machine
crashes. One time it crashed after about 10 minutes, one time after half
an hour of full fan speed. the first time the heating rate was quite
fast. The temperature reached 60°C and stayed there till the crash.
The second time the heating was slower due to an open window. But here
also the temperature never exceeded 60°C, whereas with the second patch
the temperature went to 63°C and more for a short while and nothing
happened.
Best regards,
