Re: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner

I'm trying to add a second cooling fan to my ants (push-pull)
I have some coolmaster jetflow 120 fans (12V 0,4A), but when plug-ins them in in the free 4pin connector on the secon board nothing happens, do I have to enabled the second fan somehow or am I doping something wrong?

Likely doing something wrong, but I haven't tried it with a 4-pin setup.

What wire is on top? If done correctly it should be:
Black (top)
Red
Yellow
Blue (bottom)

All black wires(what ever happend to colorcoding these days...)

On the fan it says:

+black
-black
FG black
PWM black

PWM should be on the bottom. If disconnected, it will run the fan at full speed. If connected, the fan speed is determined by the firmware.

On the Ant I was testing on the extra fan connector doesn't seem to work, testend on another one and everything works fine on that one.
I guess I could power the fan for the Ant with the broken fanconnector from my PSU, or not? What cable/connector from the PSU is best use to power the fan?
