[root at andeya1 /]# sensors -version sensors version 2.8.7 with libsensors version 2.8.7 I am sure the issue is not really related to sensors and more likely something weird in the hardware.

You can usually find the chip itself on the board, but you can't see the sensors, as they are very small and not really distinguishable. The only way I know of to physically locate the thermal sensors is to probe the board with a air dryer while watching the output of "watch -n 1 sensors". Your hardware may or may not like it ;) If you have sensors working on all systems you should be able to check whether there are actual differences in the reported temperature and fan speeds. Care to share the data with us, comparing the silent system with a loud one? -- Jean Delvare
