I operate some single board computers, like the Raspberry pi3, pi4, and pi5, and LibreComputer Le Potato or Renegade as mini-servers with active and passive cooling. One thing I've run into is thermal throttling. To protect the hardware, when the CPU temperature gets too high, the board will automatically reduce the clock frequency. Reducing the clock frequency reduces the power usage which prevents the CPU from over heating. I prefer the performance of a higher clock frequency. So, I'll commonly overclock a computer if I'm using active cooling (fan and heatsink). To prevent thermal throttling as often, I'll set the fan to turn on at a temperature lower than the thermal throttle setting. However, for the LibreComputer devices, the thermal throttling is defaulted at 60 degrees C, versus 80 degrees C for the Raspberry Pi default setting. I wanted to change the defaults, so after an Internet search, I found the commands below:
Set the thermal throttling limit to 75 degrees C instead of 60 degrees C.
Set the thermal throttling limit to 75 degrees C instead of 60 degrees C.
Return the current CPU temperature.
