As I've said in other posts, I replaced all the fans on my Antminer S5s with Scythe Slip Stream 120mm 3-Pin Case Fan SY1225SL12SH units. I like how much air they push for the sound level.

What I've noticed is the fans, while advertised at 1900 RPM, are running at a variable range of 1300RPM to 1680RPM. Is there a way anyone is aware of to force them to run all the way to 1900 RPM by modifying the controls in the web interface? Or something similar? I was considering getting an inline fan controller, but I would think this is something that could be controlled with software.

Any ideas?
