Really? I rigged my software to start a pwm fan at 50% duty cycle when the temperature reaches 40 and step up a bunch every 5 degrees until it reaches 100% at 70, fan drops off to zero only when the temperature falls below 35.
When it’s near idle, the fan actually stays off all the time. Navigation with Google maps / Waze / copilot / etc usually hovers around 45 degrees, and I really have to beat it up to get the fan up to full speed.
I have a whole bunch of usb stuff plugged in. 2 cameras (continuously recording from both to sdcard, including in the previously mentioned near idle state), sound card, GPS, touchscreen digitizer.
Generally, if it’s running hot, it (at least for me) means that there is something using a lot of CPU cycles. So the first step to figuring it out is to check out the top processes.
