Re: Official FutureBit Apollo BTC Software/Image and Support thread
No; you could basically turn off the fan completely by setting these parameters for instance. This should set the fan to 1% speed regardless of temperature.
Here is my understanding of those 4 parameters. They basically set a 2-point fan curve. I used the default values as specified above.
Code:
./apollo-miner -fan_pwm_low 1 -fan_pwm_hi 1 <rest of parameters>

Thanks for the explanations, I will have to spend some time on trying to understand and implement that.
I thought the Fan temp settings in the Full Package Apollo would be using a temp curve similar to the one you showed above, except I imagined it actually curved.
But when I set the Full Package Apollo Fan temp settings to 70c / 90c, while keeping the actual miner temperature below 60c with the added fan, then the stock fan continues to run at around 1800rpm.
See screenshot.
That's why I thought the stock ASIC fan cannot be turned lower than about 1800rpm.
