Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

is there a way to stop that insane fan ramping up and down?! it is driving me crazy. intake temp is 18 deg Celsius and yet 2 x 13.5T are going crazy since i got them.
Tried all known methods but still...

any ideas?

18 deg Celcius is very good.... just need to fix the fan power.

..and how do you suggest to do that?

If you install an older version of the firmware that often fixes it. What will then happen is the miner will run at a fixed temp (say 82c) while the fans adjust accordingly. But no more cycling.
