At the New York Finger Lakes regional in 2014, Team 20 had a similar problem. As a result of 3 back-to-back matches, we had noticed that our CIM motors had become exceptionally hot, due to heavy defense. For the remainder of the event, we cooled our motors using canned air.

Upon returning, we decided it would be best to have a more permanent solution, so we redesigned the wooden block that we used to secure our robot on our cart. We added 4 powerful computer fans donated by a local company, placing them so that they would sit under the drive motors when the robot was placed on the cart. It worked well for us, especially during our summer IRI drive practices, as our practice field is not air conditioned.

Edit: If you are using a computer fan, make sure it is not attached to your robot during a match.
