Would it be possible (maybe in future releases) to control the startup fan speed?
And instead of using no-sensor-scan to ignore all temperature sensors, would it be possible to just ignore the sensors on boards/chains with problems?
I asked about this, and there is good news for you:
"would it be possible to just ignore the sensors on boards/chains with problems?"
I think this feature request would be to disable sensors per board (chain) instead of the whole miner.
that's implemented for the upcoming release
Not about the fan of course. There is nothing you can do when you are powering up a fan you get full power to it, until the controller boots and orders it to slow down. The only way to solve this would be with a hardware solution, such as feeding 7v instead of 12v for 1min or such...
