a note about vsync: don’t forget it depends on your monitor fps (Hz). The settings 60/30/20 match only in case you own a 60fps monitor. This differs to the fps-limit in nvidia control center, where you can limit the fps in generally. Vsync is just for monitor sync. At least these things are a good option to not let run you pc allways in full-load for fps-value which nobody need in a flight-sim :)… and this, to come back to topic, can avoid CTC caused by overheating
