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 not sure how u will even want this done....no power to the controller means no power to the fans so you cant power the fans without powering the controller unless you hook the fans to an external power source and let them run but that requires you to switch them from the controller to the other power source by hand. if you try hooking the external power source to the fans and keep them hooked to the controller u will most likely cause damage to bother the fans power source and the controller....also the fans will probably take a hit there too. the moral of this story is dont run the miners outdoors.....they arent made to run in those kinds of conditions. and yes a garage and shed is still considered outdoors and exposed to the elements pretty much. these should be run in a temp/humid controlled location like a house or warehouse/hosting location. if your miner is run outside and burns up bitmain will tell u too bad and wont cover the machine under the warranty based on what others have posted in previous pages.

Probably be easiest to connect the fans to an external controller and run them manually, you just need something that gives them the power they need.
Then plug them back in and power up the miner normally.
i think he wants an automated way to do this unfortunately. the first thing he should ask himself should be is it worth risking my miner running it in these conditions knowing it will kill it in an undisclosed amount of time lol. either way an automated way wont work in this case since the psu needed to power the fans will also have moisture in it since he wont be doing this manually.
