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 su= pport for the other it87 chips. I'll post the code to this list when ready. It wo= uld 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 smoo= ther 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 _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
