Notice on page 30 of the SHG2 Technical Product > Specification it says pin 18 of the ADM1026 is "PWM" : "Pulse width > modulation of fan speed". True.

If the motherboard is properly wired for fan control operation, that should work, as the adm1026 driver has support for this. Your best chance is to try simply the adm1026 driver and see how it goes. -- Jean Delvare
