The value for the “Fan Throtteling RPM” is the target value to which the fans first turn up after applying full load, and then sink down again later in the direction of the “Fan Acoustic Limit RPM”. The so-called “Fan Acoustic Limit RPM” is the desired target speed of the fans that the card can reach even if all conditions (load, temperatures, power estimation) are correct. More is not possible anyway and less would not make sense in an emergency. The “Fan Maximum” RPM should be left as it was specified by the board partner in the current BIOS, because it takes into account the specifications of the installed fans. And this either as minimum value in idle without fan stop or as curve start after starting the fans in hybrid mode. As far as the so-called PWM minimum is concerned, this is again a scaling value that, together with the given maximum fan speeds, sets the basis for the beginning of the fan curve. Now we come to fan control, which has been so broken and bent since driver 7.3 that even with board partner cards in the Wattman you can hardly do anything useful at the moment (driver 8.1). Powercolor showed us the way with the Silent-BIOS, today we follow with a tutorial for everyone that is suitable for everyday use: no more BIOS flashing and no more Wattman tricks, but a comprehensible manual that is easy to implement with our free MorePowerTool.
