Overclocking... is it time?

Hi, your processor can raise to 90 C Degrees (maximum). Allways you decrease the temp with a good or premium thermal grease and better refrigeration.

Yes, those temps are fine, but may be because your CPU is being under utilised by MSFS [this is
normal behaviour, for now] .
As long as you keep your eye on them you should be OK.

far away of stable area… and then it must specified which temp is meant

What are your MSFS graphics settings? I overclocked my CPU i7 6700K @ 4.5 on 1.30 v on water cooling with a rtx 2060 s. Still getting low FPS (20-30 fps) with B747 over dense city areas. Any suggestions?

as always… reduce the TLOD setting . The existing topics about are like “limited by main thread”.
