Hi, I'm using a RPI 4 B (4GB) with LibreELEC 9.1.501 and have a case with "build in" fan which connects via GPIO 3,3 V.
The fan is apparently doing a good job:
Without Fan:
Idle = ~ 63 °C
4K Video= ~ 77 °C
With Fan:
Idle = ~ 45 °C
4K Video= ~ 48 °C
The issue is that I can hear the fan in my living room when no video is playing even if it's very subtle.
My Questions:
1. Is there a way to control the fan so that it only activates when I am playing a video or above a certain temperature threshold (like > 65 °C)
2. If not, would it be alright to not use the fan? Should I avoid Temperatures close to 80 °C? It seems pretty high.
