I can hear and feel the coolant pump running and the radiator is warm, the top of the stack is too hot to touch, the laser thermometer has it at 130F with the coolant lines going to the radiator about about the same. Shouldn't that fan be running?
The pack temp was 110F via Leafspy.
Granted this is unusually warm for us, I know in winter I am lucky if it is 10F above ambient in the garage at 30F and the stack at 40F while charging.
Pump is activated when coolant is slightly above freezing.
Fan is activated when coolant is above 57*C (or 60*C).
Cheap (not special) over the counter electronics are fine up to 80*C. That means coolant can be 65-70*C, depending on thermal compound etc.
