Topic: is there a way to boost both fans ? (antminer S9) (Read 1045 times)
Thats exacty what I was going to suggest, just cut the 12v and Gnd lines and have them connected to a direct 12v feed so its full speed and the miner still sees the fan there and functions as it should.
Why don't you connect them directly to 12V, that way both will do max RPM possible?
Because if the controller doesnt see the fans the machine shuts down and will not hash. Honestly if you ut the PWM line and it is still not speeding up you most likely have a bad fan.
But why don't you leave pwm wiring connected just connect directly to 12v other 2 wires... It should send max rpm to controller, so it should still mine... But the rpm would me maxed..
Am I missing something?

The front fan maxes out at 6000 rpm, the back fan at about 4300. If you are expecting 6000 out of both you will not see it.
im expecting at least 3000/4000 on the back one.. but all my S9 back fan are running at 1440~1600 (they never go higher than 1600) (Even with blue cable cut)

i did it with the front fan (cutting the blue cable)
but this method wont work with the back one (only tried blue cable)
maybe the speed control on the back one is a diferent color? anyone did it succesfully?
