Yes this does help a lot. Thanks for your input.
Where did you find that heat sink/fan set up? What is the voltage of your fan? Are you running it directly from the VESC? If so, where’d you plug-in? I’m researching a heat problem now and really like your approach.
eBay - search 5v fan and heat sink. There’s loads out there and really cheap. Fan is powered from VESC - tapped into power supply to transmitter receiver unit thing.
