Uhmmmm! I'm probably missing something here, and it's true I haven't had my nap today but running at 180 with the fan on all the time sounds normal to me. It doesn't seem to me that steveg needs to start working on his cooling system just yet. If his thermostat is 180, it doesn't matter if the fan is wired to be ON all the time or not, (just like a mechanical fan) the thermostat is controlling the temp. Right?
