No it's not a joke. :)

The 9920 has twin fans and the motor just has the RCM heatsink. It's geared high, I think 20/51 and I don't get any problems. The ESC gets hot but by no means dangerous (before the fans I couldn't get a 5min run without it thermalling). The motor stays warm. My average speed is 40 though, so nothing really pushing it, I just like the power and speed there for when and where I need it. ;)
