40x40x10mm Ball Bearing Motor/ESC Cooling Fan - 5V, Compatible with RC Vehicles

Big fan of this big fan. Its pretty cool. If it's for an off road vehicle consider attaching a small piece of metal screen over the blade to keep debris out

Ordered 2 of these fans to put on a motor cooler bracket on an r/c car. The first fan stopped working before I stopped the car the first time to check motor temps. The second fan stopped working on the second battery pack. Don't waste your money. Spend a few dollars more and get a fan with an aluminum housing.

I like the product seems solid, and is working well so far. Also has the hex cutouts on one side for a hex nut to sit so you wouldn't need a wrench if that's what you are needing. . Common size screw-holes, comes with fine thread screws, I needed to use coarse thread in order to screw into my heat sink. I just purchased another for a project.

Does not fit velenion esc for traxxas

Came with wore cut in half. I ordered this for my rc car have not had time to work on it. When I finally get a chance to use it can't wires are cut.

Great fan works awesome cools my engine right down very powerful

Moves air well, isn't quiet.

I'm using this for a D4 and it's doing well so far. No complaints.
