Ah … Silly me just assumed you’d be on a 550 or 570, that explains why you’re down a little on MSFS performance. AMD is very good for dynamic core cooling and if I’m right you have a Wraith Prism cooler the same as I do (it was originally intended for the 5 series) so don’t worry about heat. I can’t speak for the 3700X but with PBO my 3800X doesn’t change voltages as far as I’ve noticed.
