How to fix over heating problem with Cruise Speed Controller mounted inside the plastic control box

I used heat conductive paste between Speed Controller and heat sink

The heat sink then becomes the lid of the plastic box supplied in the latest kits

I mounted the plastic box to the under side of the battery rack heat sink facing down

So there was plenty of air flow over it

No more problems with the controller getting to hot sealed inside the plastic box with no air circulating around it to keep it cool
