If you buy a copper pipe 1 3/4 in diameter, cut it in half so u get 2 semi-circle pieces of pipe. Then cut those pieces to be 1 1/4 inches long. Polish the inside and put some thermal compound on the inside. Then get a pipe 1 inch in diameter and solder the two end pieces you just made. Drill 2 1/2 inch holes 1 inch from the end of the pipe. Then drill a 1 inch hole in the middle and put a small muffin fan on the top so it’s sucking air out. This device becomes very cold and is a great way to cool off motors easily.

luckily enough, when disnging brackets for our CIMs and drills that are used on the drive train, we included a heat sink, however, some overheating occurs no matter what.
in the past we used a anti static circut coolant that goes about -60degrees F and -51degrees C. be careful, it is intended for industrial use only,and is the kind of stuff that gives you instant frostbite if applied to skin. as someone who has had cold hands on the team, trust me and keep this safe if you get it.
its called freez-it, and is made by chemtronics
hopefully this helps
