I am trying to get 2 Noctua NF-F12 Industrial PPC-3000 fans working on my Antminer S5. Plugging them into the PWM connectors does not work. They spin a few times and then quit. The S5 is Powered by a Corsair 750 Gold series PSU. Any help is appreciated.
They most certainly work. I probably know what is going on...you might have put connectors in reverse orientation.
There is a bump on one side of the connector that is preventing putting it in the correct orientation.
Clip it (the bump) off with a nail clipper or something similar to flatten the area, then it will fit in correct orientation just fine.
these ones (just to make sure)?

This combo costs less, is more secure regarding internet loss "bug" and gives similar db level in comparison with 2 Noctuas.
