This makes sense! Thanks!
Additionally also the performance setting should be kept like this. I
always have the problem when having used passive cooling that on its way
down from max-temp the CPU is forced into P0 whereas P1 would conserve
power and cause less heat.
Manually resetting to P1 just causes it to be reset to P0 after some
seconds. Tools like autospeedstepd (very nice BTW!) are afterwards also
unable to switch the CPU to P1 again. If this would work it, passive
cooling would make more sense ;)
