Is there a way to fire up the fans on the S9 for a period of time (let's say like 15 minutes) without any power running to the the hash boards (or even controller if possible)? I have an application where the S9s will be in an relatively external environment, and I want a safe way to start them up while ensuring there is no condensation when the unit is powered up. The condensation could occur after the units have been shut down and have cooled, and the ambient humidity has condensed. Assume I cannot have a back-up heater installed.
Any simple modifications anyone can think of? Maybe a small change to the firmware?

im shocked u arent commenting on him running a high powered electronic device in such conditions to begin with. i expected u to beat me to it bud.
