Best way to cool CIM motors?

[theCADguy]

There are only certain motors allowed on the robot, listed under R18. The only computer fans allowed on the robot are the tiny ones included in the kit of parts, or that come with COTS motor controllers. I wouldn't expect any of these options to be very successful in cooling a CIM.

The fans we used were very large, and were designed to cool large server computers, and could provide a flow rate of more than 100 cubic feet per minute.
