Hobby Fans RC Motor Heat Sink with 5V Cooling Fan Fit 370 380 390 2838 2858 2845 Size Brushless Motor Heatsink for 1/14 1/16 1/18 RC Car Truck Buggy Crawler

Does the job well on my mini E revo. Quite loud, but worth it for the cooling ability!

This thing moves air pretty good. Keeps rc car motor nice and cool

Fits my e- revo mini perfect. Moves a lot of air. update, for those saying this won't work. You have a two plug trying to go on a three plug. It will work, I used #3 and try different spots till it works.

Had to splice wires but it works well on my 1/10 scale set up on my mini basher ;)

Great little gimmick, helps extend regular run time a little more and keeps wear and tear off the electronics

Sure it would have been good with the correct plug. I didn't pay attention

Got this for my granite grom because where I live it gets pretty hot and I would only get through a half a battery before it would burn up and shut down. Mind you this rig is completely stock and I’ve never had to replace anything on it. I replaced the motor and installed this heat shrink/fan combo. I just ran my grom pretty hard, nonstop through 2 fully charged 2s batteries and the motor never shut down prior to the batteries dying. I gave it a 15 minute cool down between each battery. This combo is a must and I will be ordering another for my Mojave Grom when I get it. Thank you!

please, for the love of your wallet, don’t buy this. biggest waste of 10 bucks ever, damned thing worked for 5 minutes before going out, didn’t even try to spin, just dead. tried it on two different cars and the same result.
