Prosine 2.0 fan operation

Prosine 2.0 owners, does your fan run periodically when the charger is supplying little current (1 amp or less)? In this situation mine kicks in for a couple of minutes every 30 minutes or so. The fan is operating correctly according to the internal temps on the display, so the root problem is the internal temp going above 130F with little or no load. Happens even with the ambient temp at 60F. It's annoying, and none of my power converters ever needed to run the fan even with a 10 amp load.

    The fan runs, as you summarized, in response to a T-Stat closing.. now due to the way it is mounted I don't really notice the fan on the Prosine (some comments later) but I also have a converter.. For assorted reasons I prefer it to the Prosine when it comes to doing it's job (The prosine can do it though and do it well. I just like the charge wizard better).

    I have seen that fan running (Same type of controller) even though I was not connected to shore power and NO power was flowing into/out of the box. It was OFF, only the fan was running.

    I have a Xantrex TrueCharge charger which is probably close to the charger in the Prosine 2. My fan runs constantly even at 1-2 amps. Mine is located in a pass through and I can't hear but it would be annoying if I could.
