My crash course on motor technology taught me this:
cooling sprays are ok, but they don't get to the heart of the problem. you're cooling the casing but that's not the source of the heat... the heat is in the armature and whatnot... you can help all that by getting more air in there and keeping it moving...
i like mini muffin fans...

: Well....in past years, my old team always had the issue of motors getting extremely hot, though not usually enough to affect preformance in a match, but giving trouble if the matches were close together. I think it was a combo of not having enough air flow around the motors, and not using the muffin fan at all. Let's just say we purchased a lifetime supply of Freez-It
