This suggests the following things: 1* This is probably the hardware default, contrary to what the datasheet says. 2* Your BIOS doesn't enable temp2 on regular boot, although it obviously enables it when you enter the setup screen (you saw the temperature update there). > I have now done modprobe w83627hf init=0 > (...) > Unfortunately it does not change (I ran cpuburn for a few minutes, fan > speed increased as expected but no change to temp2) You are lucky that the fan speed changed at all. If it was based solely on the CPU temperature it wouldn't have. I guess it somehow also depends on the system temperature (which is not disabled and probably cannot be). Unless this is a self-regulating fan? Skipping the init would have preserved a correct setup done by the BIOS, but since such a setup was not done in the first place, it didn't help. No surprise here. So, what next? You can just reconfigure the chip on the fly, thanks to the following command sequence: isaset -y 0x295 0x296 0x4e 0x01 isaset -y 0x295 0x295 0x52 0x00 isaset -y 0x295 0x296 0x4e 0x00 Preferably you would prepare the lines in a script so as to run them all in a row. It is important to make sure that nobody accesses the chip between the commands. You can run this sequence either before loading the w83627hf driver, in which case you would still need "init=0", or after the w83627hf driver has been loaded. This should hopefully re-enable temp2, for good this time. Of course this is only a temporary method. Now that I know what should be done, I will update the drivers so as to enable the temperature channels by default - maybe with a warning in the logs since the channels may actually not be used (no remote sensor connected). Expect some delay before the update reaches your distribution kernel though. Thanks, -- Jean Delvare
