Hi blissz, firmware made a big difference to my temps and the noise reduction is God sent thank you, but then at random one of my d3's was overheating 100 degrees+. I noticed the fan speed being around 2000rpm instead of 3800-4500rpm.

I flashed official bitmain firmware on that machine then few hours later one of the other d3's did the same after a network interruption and coming back online again that machine also stuck at around 2000rpm resulting in 100 degrees+ and super high hardware errors.

Please look into this issue as the firmware really makes a difference, but is not worth the risk if the fan gets stuck at 2000rpm. The red light on the machine flashes instead of the green when this happens.

Rebooting fixes the stuck 2000rpm fan issue temporarily. It will happen on any of the fan profiles as well as when I set a custom fan speed of 50%. It seems it might have something to do with when the fan speeds are suppose to spin up loud at startup, since it's quiet at startup now I think it gets stuck there and never ramps up again to the desired fanspeed but stays stuck at that 2000rpm mark.

Havs anyone else encountered this?

I've seen similar issues too. I've had a board peg to a random 100+ degree in the 'silent' profile with all of the settings down low (e.g. 400 freq, 11 volts). The other two boards are at like 70 degrees.. but the third is 105+. Its scary and I think the fans should be kicking into higher RPMs when 90 degrees is exceeded.

Thanks for this, I've seen it once before. I know where it comes from. The displayed Temperature is incorrect, so nothing to worry, but I will solve it in the next version

Thanks. Awesome work on this firmware, can't overstate that enough.
