Re: "ICE" Cube Cooler Kit
Forced air cooling on an open RS-550 or 775 motor does quite a good job at keeping the motor cool. The motors already have a fan but it is integral to the motor and driven by the motor shaft, so it would obviously not run when the motor is stalled or not running.
On the other hand, cooling a closed CIM motor does almost nothing to the internal temperatures as there is very poor heat transfer between the hot parts (armature) and the case. See http://www.chiefdelphi.com/forums/sh...13#post1215913 for some nice data on CIM temperatures. That said, I have seen benefit to forced air CIM cooling when the fans run between matches (10mins or more) or between batteries during practice sessions. But the weight is best spent elsewhere during a match.
