Hi, Saphex
    What you said in comment #14 is right. It seems that the FAN is controlled
by the BIOS. The ACPI FAN device is bogus and it can't control the true FAN
device. 
    It seems that the EC notification event is triggered while using Fn
combination, which will trigger SMI interrupt in the correspond _Qxx object. In
such case BIOS can control the FAN speed according to the user requirment.
    So on your laptop ACPI has nothing to do with the FAN. 
    thanks.
