How do the internals of your miners get below the dew point of the air they're in? Might not be a scenario that's actually possible.
Because they are not housed in a conditioned building, they are housed in a shipping container open to the elements.
I take it the miners are sitting directly in front of the cold air vents feeding the area as spot cooling? I've seen a lot of rather horrid industrial shop-floor environments at that is the only way I've see it happen to power equipment that has been powered down for a while... Partly for this reason you never ever want to duct cold air directly onto/into power electronics.
IF that is the case either move them or deflect the airflow around them as pre-heating or running the fans does not address the root problem.
There is no ducting directly into the miners, but see response above to VRobb. When the mine is running, there won't be any issues. My main concern is when it is shut down (it will periodically be shut down, more frequently than a typical mining farm) the entire container and mine will cool. Once cooled dew and condensation will occur. I do have a back-up heater in place, but, there will also be times when it too doesn't have power.
So any idea's on how to rig up the miners so the fans can turn on first, as per my OP?
Cheers
