    Fan for esc or motor

    Hey guys,
    I ran my slash vxl earlier today and burned my finger on the esc while trying to shut it off. I checked the temps of the motor and esc and they were both over 200* f. I read somewhere that 160*f is the highest healthy temp for my motor to be running at and I want to purchase a fan for either the motor or the esc or both. What do you guys recommend i get the fan for, the esc, the motor, or both.
    Thanks!

    Before you throw money and fans at your truck, recommend checking your drive train, make sure nothing is bound up causing the motor and ESC to work harder than they should.

    What gearing are you running?

    Have you checked the mesh between the spur and pinion?

    What happened between your electronics running normal temps and them getting super hot?

    I tried that Integy heatsink with single fan but I took it off pretty quick.

    You need to check things mentioned above before you start buying fans.

    Also, I'm gonna assume you are running 3s lipo if things are getting that hot.

    I had just replaced the spur gear before this happened so could that have been causing the problems? Like if they were too close together or something?

    It is the stock gearing and yes I am running a 3s lipo

    Both. Better safe than sorry.
    As far as what...lots of possibilities. Check the threads and you'll see lots of great ideas.
