It has alarm outputs that can tell another chip on your system to do it, though. Reprogramming the limits on the fly does sound weird, there are better ways to achieve conditional fan activity. > Sorry I can't crack the case open ;-) sensors-detect didn't suggest > anything except sis-96x I'll drop the complete output here.

I had expected that sensors-detect would suggest both the adm1021 driver (for a MAX1617) and the lm90 driver (for a MAX6657), and pick the former arbitrarily. When comparing the sensors-detect code with the dump you sent, I just cannot get why it isn't the case. Both tests (MAX1617 and MAX6657) should be positive. Are you certain that you are using an up-to-date version of sensors-detect? Please try with the CVS version: http://www2.lm-sensors.nu/%7Elm78/cvs/lm_sensors2/prog/detect/sensors-detect If it still won't detect your chip as neither a MAX1617 nor a MAX6657, and you have some perl knowledge, it would be great if you could add some debug in the adm1021_detect and lm90_detect functions (for $chip=2 and $chip=4, respectively) and see where the detection is failing exactly. If you don't have such a knowledge I'll send you a modified version of the script for you to test it. > Client found at address 0x10 > (...) > Client found at address 0x6a I wonder what these are. Could you please provide dumps of these as well? I'd also be interested to know the model name of your laptop, in case I can find some technical documentation.
