Unlike the reports from `sensors`, the CPU temperature looks right (about 37°C) and the CPU temp is higher than the MB temp. Again, there is a lack of consistency, so it is difficult to tell which is which, or how much I might rely on either one as a metric to trigger a shut down of the machine. > > Do you see all fan speeds in the BIOS?

When I rebooted, only 1 of the fans was reporting an absurd rotational speed. The Coolant Fan was jumping up and down all over the place in the advanced screen, and reporting about 57,000 rpn on the main screen. I swapped the Coolant Fan and the Pump, putting the Coolant fan on the CPU_FAN connector, and the faulty reporting stopped. The "musical sensors" under Linux does not seem to have stopped, however, although I am not entirely certain of that. Oddly enough, however, I am certain of the fact in the current state removing the Rear Fan #1 from the CHA_FAN1 connector drops fan2, but connecting the pump to it does not return the monitor point. Putting the Rear Fan #1 back does restore it. _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
