Over the weekend I built a new PC and installed MSFS fresh. I also installed afterburner to monitor temps during a flight around EHLE in the 152. Windows energy scheme maximum performance. MSFS priority set to high. CPU 67, GPU 61 but… The fan of my PSU (Sharkoon Silent Storm Zero 850W) spins …

Changed the PSU for an ASUS ROG STRIX 1000W. Delightful silence. Sharkoon blew it for me with their PSU.
