The Raspberry Pi4 starts to throttle, reduce frequency, with temperatures over 85c. When flying the DC-3 Dakota at a steady cruse altitude, in a low scenery dense area, the core temperature was reported to be ~75c. This was with ambient temperature of ~24c. The temperature rapidly dropped to ~45c when the cooling fan was energized. There was no heat sink installed for this test. FlightGear was running in fullscreen mode on monitor 1 and terminal was running on monitor 2. Screen resolution was possibly 1024 x 768. | The Raspberry Pi4 starts to throttle, reduce frequency, with temperatures over 85c.

The fan in the photo is a Noctua NF-A4x10 5V. It is installed with two rubber bands forming an X. Then the fan is simply sandwiched in the middle of the X. The ends of the rubber bands are looped over the ends of the four standoffs. The rubber bands, in addition to holding the fan, help to isolate vibrational noise. | The fan in the photo is a Noctua NF-A4x10 5V. It is installed with two rubber bands forming an X.
