Thanks. Could be, but the fan control has never worked ideally under GNU/Linux on this machine. Besides, shouldn't the processors be throttled down based on the CPU temperature, even if I simply forced the fan to stay slow? No warranty left. I tried cleaning the fan with air, without opening anything up. That obviously didn't make a difference. I'm hesitant to open up this machine, but might.
