I almost go crazy. Hi Hector, I've been working to add automatic fan mode to the it87 driver. It works on the it8718, but I'm still changing the sysfs interface, and adding auto mode support for the other it87 chips. I'll post the code to this list when ready. It would be great if you could help test it on your it8705_v2, I don't have one here. Auto mode varies a bit from chip to chip, and for the 8705, for different versions of the chip*. For your it8705_v2, auto mode allows 5 discrete fan speeds: off, low, medium, high, and all fans full speed. You could get smoother control by using the software pwm mode you already have working along with the lm_sensors fancontrol script. * Note that the datasheet version does not always correspond to the version that the chip reports in Global Configuration Register 0x22:[3-0]. For example: datasheet chip-reported version 8705 0.3 0x02 8712 0.7 0x06 8712 0.81 0x07 8712 0.9.3 0x08 -Frank
