Hmmm I'm a newb and didn't realize there were different modes. I used whatever it starts up in (assume primary)
I did get some heat buildup on the longer / steeper climbs but the fan kicks on (boy is that thing loud) and brings temps down to 190 or so fairly quickly. Once it shuts off temp begins to build again. I don't think they were getting much above 205 or 212 once the fan kicks on.
On flat ground, unless air temp is above 85 the fan never kicks on.
