So, the correct sequence now that you have all the tools installed would be: rmmod lm78 rmmod w83627ehf modprobe i2c-dev isadump 0x295 0x296 i2cdump 1 0x2d b > > (...) > > Could be that temp1 isn't wired at all.

Maybe an offset needs to be applied to get the correct temperature. That would be unusual for a thermistor on a W83627DHG, but we can't rule it out completely. > > (...) > > Is the BIOS displaying it?

The Northbridge speed is around 2000 in the BIOS. In your original post, fan3 was displayed at 1240 with a clock divider of 8. How many fan speeds does the BIOS show, and can you match some of the values with what "sensors" displays? The W83627DHG has 5 fan inputs, which should be enough for most motherboards, so it would be really surprising if your northbridge fan is connected to another chip. -- Jean Delvare
