If I go into my Antminer's status screen, under Status, and Miner status, it says that the RPM of my fan is 15120. The temperature of both blades is at 35. I would be really curious to know the speed of the fan from other users on this forum.

This is nuts. I'm supposed to sleep in the next room. If I can't find a solution for this I'll have to turn it off at night and that'll just kill my possible ROI.

Ok, so at 40c fan spins about 2700rpm.
This might be temp sensor or fan speed controler.
If you want to slow it down as far as i remember put 47ohm resistor in to red wire.this will cut 12v in half.

Just measure voltage on wires and a bit of soldering and job done.
