Heat sinks are not very efficient at transferring heat away from the motor. For TC just put a fan on the chassis or on a mount to the rear of the motor blowing air onto the motor.

Both of them are works. Use fans if you want heat spill out quickly, or you can use a heat sink. If your vehicle produce heat quick and large, get a decent fan will be a better choice.

Just a 40mm fan mounted behind the motor blowing air onto the motor with a gap of 5-10mm. I use Ride servo tape to stick the fan down to the chassis as it's really strong. Heat sinks are not needed with today's brushless motors.

we still run silver cans in our gt class and was thinking about them as well.
so for 17.5 just a fan would work?

If the fan is on the rear of the motor it should be blowing away from the motor, extraction is far more effecient. The contact between the motor and heatsink will always be bad compared to PC heatsinks but the heat will still move through to the heatsink, the heatsink greatly increases your surface area which is the part you really want to cool to see big drops in temp. The Nosram is one of the best designs on the market but it ain't cheap.
