I know this has been brought up before, but I am not happy with the cooling on my s9's.  It's a bit warmer here and two of my units run up to 85c

I am considering building an "exhaust box"  and pulling from that box with this sort of fan:

These fans pull high volume and pressure.

The issue is the PWM feedback to the antminers.  If I disconnect the fans, the units will shut down.  I suppose I could just cut the fins off the fans and let them spin there, but that draws an additional 150watts give or take.

I could try and connect a PWM generator and trick the units.

Does anyone have a hack for disconnecting the fans from these units?  I just can't have them run this hot.  They wont last
