Neu 1515 Heatsink with cooler?

[Kajman]

Yeah, I will get it, one of heatsinks and high rpm fan on it. Good is, that autumn is coming and outside temperature will be much lower, which will let me have fun longer.

I don't really understand one thing, people run 2200kV geared for this speed and claim to have lower temperatures, I have checked different motors within kv range 2000-2700 and gearing vs. kv for the same speed gives similar temperatures for me. Why should it be different? Eagle tree logs would say something, but I don't have logger.
