Hello everyone. I'm a CoinTerra refugee and new to the Spondoolies camp. Just got an SP31 up and running over the weekend.

I can't seem to find any definitive explanation for setting the "Fan Speed" parameter. The documentation says the fan speed affects the unit's hash rate.  But is the effect of fan speed on hash rate direct or consequential?  That is, is the fan speed setting directly used in setting the ASIC clock rates, or does a faster/slower fan simply mean cooler/warmer ASICs that subsequently mean faster/slower hashing?

The reason I ask is that my miner is in relatively cold (60F) server room and the chassis temps are holding at 21C front and 59C/59C rear.  So I was wondering if it's possible to devote less PSU power to air movement, and more power to the ASICs by reducing the fan speed. Or is such an endeavor a fool's errand?

Any sound (pardon the pun) advice on the matter would be greatly appreciated.
