As noted in another thread, sometimes when I turn it on the fans are at full speed, processor=1860 RPM, rear=2040 RPM. Restartign windows settles them down to regulated speeds.
I have just had it happen again, and went into the hardware monitor. It showed processor thermal margin=0, internal temp=25, remote temp=27. The machine had been off for hours.
After restarting windows, the fans settled down immediately and BIOS showed processor thermal margin=50, internal temp=31, remote temp=33 and fans at a more appropriate processor=1020 RPM, rear=1200 RPM .
What could cause the intermittent problem with the processor thermal margin value, which was clearly in error on powerup and which seems to be making the fans go to max?
