Hi Jean-Marc, That's great that you've modified it87.c to handle your IT8720. Why don't you go ahead and post your patch to the list, I'll be happy to have a look at it. My first priority is adding automatic mode support for the 8718. I'm adding auto mode support for the 8720 and other chips at the same time. But I'm still not ready to post that work yet. Anyway, as far as on/off and software pwm modes go, the 8720 is almost exactly the same as the 8718*, so you can do a simple search through the code for conditionals on the 8718 and add the 8720 to them. (Sounds like you've already done that.) I have nothing to add to Jean's excellent answer regarding the voltage inputs on it87. And I don't know what's going on with in0 on your board either. -Frank * The one slight difference I'm aware of is that the 8720 uses ec register 0x0b bits to control pwm4 and pwm5 in software pwm mode (since it has 5 fans but only 3 pwm channels): bits RW def notes 3-2 RW 11b pwm5 same as: 00b pwm1 01b pwm2 10b pwm3 11b none 1-0 RW 11b pwm4 same as pwm[1|2|3], codes as above The 8718 also has 5 fans and only 3 pwm channels, but does not allow choosing pwm4 and pwm5 control as above.
