Hobby Fans RC Cooling Fan RC Car 40mm Motor Fan with Heatsink for RC Car 1/8 1/10 540 550 F540 3650 3660 Motor, Black

I was worried this fan would be ridiculously loud but it's actually not that bad. Definitely noticeable but not as loud as some of the smaller fans on heat sinks I've heard before. Fits my 540 can motor perfectly and the cable is more than long enough to reach my receiver.

This is a great upgrade with a strong fan keeps temps in check

I purchased this to put on my Traxxas HOSS. The very first run after installing this heat sink and fan, my motor temps were 20 degrees cooler. Highly reccomended!

I got it and went to install it and the black wire was pulled out of the connector. It looks like it was never landed correctly. I took the connector apart and tried to repair but the fan doesn’t run when installed in my rc car. I don’t think it is making a good connection. Those terminals are tiny and they really aren’t meant to have the wires disconnected and then reconnected

Fan lost 6 of the 9 fan blades after one run. Aluminum heatsink works just fine. The plastic housed fan is junk. Get an aluminum housed fan and you will be all set. Just means another $15 to $20 more you will need to spend.
