If it jumps all over the place no matter the setting, then you can safely conclude that it is left floating and should be disabled/ignored. > I will further ask questions about the rest of the detected chips as I > get to them, though I'd appreciate any thoughts on the above temperature > sensors. Given that the board vendor used a dedicated LM90 temperature monitoring chip to track the CPU temperature, I wouldn't be surprised if most or all of the IT8705F temperatures inputs were left unused. The it87 driver forcibly enables temperature monitoring channels if they are found all disabled when the driver is loaded. It probably shouldn't do that, especially given that each channel can be configured in two different modes (thermistor and thermal diode) and the driver has no way to know which mode would be correct. Incidentally, your modes configuration for temp1, temp2 and temp3 matches the arbitrary default set by the it87 driver, so it is possible that all sensors were indeed disabled originally. I will fix the it87 driver later today to no longer arbitrarily enable temperature sensors. This should clear some confusion as least on some boards. What temperatures are reported by the BIOS on this machine? This would be a valuable hint. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
