Hello everyone, I have a Granite BLX 3s and have been running it hard since I made the purchase. Unfortunately for the past 2 weeks we've had an oppressive amount of humidity and heat in New York City which has lead to extremely high motor temperatures. Before anyone asks, I do have a motor fan and even this struggles to dissipate the heat. I think I've found a solution that aids motor temps; according to my readings and conditions by approximately 20-25 degrees Fahrenheit.
Step 1:
Definitely have a motor fan to begin with.
Step 2:
Purchase thermal compound designed for computer processors. (I am using Arctic Mx-4 from Amazon)
Step 3:
Remove motor heat-sink and apply a generous amount to wherever the heat-sink comes in contact with the motor. Make sure to spread this out with your finger or Q-Tip.
Step 4:
Reapply the heat-sink and wipe off any excess that may have oozed out. I recommend a paper towel with alcohol since the thermal compound can be quite sticky.
I know some of you may be thinking doesn't this stuff attract dirt? You're certainly right in thinking that, but if you wipe a lot of the extra off, dirt struggles to penetrate the area between heat-sink and motor. Also for those of you who may be wondering my conditions are as follows so your mileage may vary... ~95 degree Fahrenheit heat, ~75-85% humidity, hard bashing on grass, gravel, loose dirt, and a skate park, stock 3s electronics (esc/motor)
I've been using this for about a week now, and I'm hoping this helps anyone with overheating issues. Just make sure you already have a fan installed to properly take advantage of the thermal compound heat conductivity!
