Sorry for the confusion...101 F was the outside temperature.
The engine temps hover at around 85-87C. When it's really hot outside, it climbs to 90-95C, and then the aux fans kick in, (seems like at around 97C), and the temperature goes back down to around 85-87C.
80C seems a bit cool for normal engine operation...
