I wont even move my plate from 100% coverage until it's north of 70-80 degrees, and to be honest, I see no reason to even budge it unless I know Im going to be driving hard for a while. I left it at 100% for one of our cruises, I just didn't drive 100% the whole time lol. No issues.

Point is, unless you are creeping past 230+ and it's still climbing, you shouldn't be worried.
