Yes pipeous is right. Do not use a fan on a motor that is over heating as a band aid fix. Tune your motor not to overheat, then put a fan on it just as assurance plus your motor will get up to safe operating temperature slower. In 105+ degree weather a fan makes a big difference especially on a track where temp are 135+ degrees. You might get an extra 5 minutes of safe operating temperature running with a fan. And I also have found capacitors to help with temps. Generally you want the temp to be safe at the end of a run with as much power as possible during the run and that is where the fan helps. Also a fan can cool the motor at the end of a run for the next run. You get longer better performance starting with a cool motor. 110 degree days here overheat nitro and electric on a track if they are geared over 25mph its just a matter of how long can I run before overheating.

Keep in mind caps can be wired in series and parallel also. If you want to compare caps charge it and connect it to a multimeter. You can watch the voltage go down. That'll tell you which cap can store the most energy if you are making some or have several to choose from. The Eagle tree 150 amp v3 can go to 200amps but supposedly loses a little accuracy over 150. The goal is to go fast, not overheat batts-esc-motor, and get long runtime. The eagle tree maps amps, watts, voltage, mah, rpm, mph and more in real time puts it on a graph so you can see how every little change affects your ride throughout the whole run.
 
Thats lookin pretty controllable. The rpm sound low too. That'll hopfully keep it cool. Now you need some cones and track dots.
