MGM Compro 16016 - NEED HELP

Oh, about the heat sinking. Aluminum is a good conductor of heat. When you run a fan on a heat sink, the purpose is to help the sink dissipate the heat. Unfortunately air is NOT a good heat conductor. The best way to get the heat away from the controller is to use a big heat sink. The biggest heat sink available on an RC car is the chassis. Lots of mass and surface area. If you have the space to mount the Quark on the chassis, you'll likely not even need a fan on it. That's just what I think anyway.

On my vehicles, I turned aluminum standoffs that bolt to the existing engine mount holes. I then used a 1/8" thick piece of aluminum and bolted that to the standoffs. The whole thermal pathway is made of aluminum and that stuff moves some heat. Just make sure that you use some quality thermal grease, like arctic alumina and the secure the esc to your sink (whatever it is). I say to secure it, because the thermal grease will "set" and get really thick. If the esc moves around after the grease has set, it will become less effective.
