Aluminum Alloy RC Electric Motor Heat Sink Heatsink with 5V Cooling Fan for 1/8 1/10 RC Car Truck Buggy Crawler 540 550 3650 Size Motor

This fan was very easy to install and remarkably lowered the post run temperatures of my motor.

Fits for Traxxas brushless motors. Fan seems good quality. Spins fast. Only complaint is that only two screws line up to hold thr fan on to the heat sink. Even though there are 4 screws in the fan, 2 of them are glued in place to look like they are holding it on

Heatsink and fan really keep my velineon motor temps down. Was running at 180 out in Phoenix summer hear keeps it down to 130. Cools down even faster. Fan blows softly but it seems to be good enough. Heatsink fits good on the slash 4x4 had to bend it a little tighter to get it to not roll around. Maybe a little hi temp silicone to hold it in place. Overall happy with the $8 fan heatsink! Cable was plenty long enough about 10" and had the right receiver plug.

Rc car fan could be a little stronger but works fine

its a good lil heat sink id suggest puting thermal paste or thermal pads on it be for zip tieing onto the motor and to put longer screw in the 2 holes that line up and puting a lock nut on it. it droping motor temps from 200 to 150 to 167

It did the trick, the only thing I have a problem with it, is that if you have the wire in a weird position or some decision doesn't like it will not put off enough power

The fan is slow and doesn't seem to move much air. And this thing is big, had to cut out a lot of plastic around my motor to fit it in there. However it seems to work well. My custom hummer R/C car works well and the 550 motor doesn't get hot at all.

put this on my trx6 over a apex 550 motor. it just snaps right over the motor the connector plugged right in next to my lights. put it though a 4 hour trail run through water and mud. the fan is not the strongest but its surviving im probably under volting it though
