[SOLVED] How to Overclock gpu fans?

To get more technical. The windings in any given fan will determine the rough rotation speed minus the resistance of the air. At a given voltage you will get a fixed RPM. With RPM control it will increase voltage (Or pulse width) until the RPMs equal the target.

Now where that might be useful is if you changed out the fans on the card with faster ones, and needed to reset the max RPM so they could be properly controlled. Otherwise an RPM driven algorithm would always prevent them from running at full speed.

But since you have software control already and you aren't swapping out the fans little point. Also editing GPU BIOS can easily lead to fancy video card shaped objects of dubious value.

the fans in my gpu are 3740 rpm and its an rx 580 it needs 95mm fans know any faster ones?
