I got a good question for yea.....
Last nite I ran the stock heat sink (blue) in modiflied once...
Next ,I ran the car car with out the stock heat sink....
I measured the temperature of the motor after running with & with out this part.
Was I surprise to find the motor was running alot cooler running with out the blue heat sink !!
Wazzz`s up with that ???
Maybe a piece of thermo tape to help conduct the heat could help?
For rite now I have stop running with this heat sink..
