I understand, and it’s very likely that I didn’t express myself clearly.
My point is that the CPU seems to experience high loads quite frequently when running MSFS2024, but this isn’t the case with MSFS2020. Once again, I acknowledge the fact that some optimizations have been implemented. However, when comparing the loads, I don’t see significant differences between the two versions that would justify the high CPU load -more than usual in MSFS2024-
Moreover, when the sim crashes, the CPU remains under heavy load, and more than 20GB of RAM are still allocated—even when the sim has completely stalled.
This leads me to believe that something might not be functioning as expected. Between the fans and the AIO cooler, my case has 10 fans, so trust me when I say I can hear them when the free flight is loading! 
Cheers, and thanks for your response!
