Well normally all recent CPU have an embedded digital thermal sensor, but apparently it isn't returning proper values in your case. Note though that these integrated digital sensors are documented by both Intel and AMD as having very bad accuracy at low temperatures. As the sensor is can't return negative values, the "0" you get may simply mean that your CPU is very well cooled. But it is also possible that your CPU digital sensor is defective, I don't know. There have been many such cases reported in the past, for specific CPU lines. Either way, most boards also have a monitoring chip, which can monitor several temperatures, and often one of the temperature inputs is connected to an analog temperature inside or underneath the CPU. This may be what you're seeing in the BIOS / Windows. > Im very sure the sensor works nice because windows and bios work fine too! > Also the fan can be controlled via windows or the BIOS.

Yes, it is likely that the Super-I/O is responsible for both temperature monitoring and fan control. > Please let me know if i have to send a mail to MSI or Finteck for that > datasheet?

Your motherboard's manual doesn't mention the Super-I/O chip name, unfortunately. Asking MSI and/or Fintek for a datasheet is always a good idea. But first you have to ensure this is a Fintek chip, and find the exact chip name. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
