At the current stage, the fans are just connected to a 12V supply. Whenever you turn the cluster on, all fans will operate on full speed. It would be nice to regulate the fans in one or the other way:

  • Add a thermoresistor to the circuit to drop the voltage on rising temperatures.
  • Regulate the fan voltage by the Raspberry GPIOs. It could take its own CPU temperature or even ssh into the nodes and take their temperatures.
  • Regulate the voltage for all fans individually by the Raspberry GPIOs. ssh into the nodes, take their CPU temperature and regulate the fan directly behind the corresponding stack.

Every of the above options would be an improvement over the current situation.
