A 30C drop shows the cooling is efficient – but what does that 30C of heat say about efficiency of the controller motor prop setup?

So that means that when James observed a 30C reduction in heat readings from the sensor using his water plate/air fan cooling setup for the same power and load, the system is resonably effective. Since the temp sensor is at the hottest location that is the toughest to cool, temp drops there actually mean something.
Fair winds,
