Hobby FansRC Cooling Fan 28000RPM Alluminum RC Car Motor Fan with Heatsink for RC Car 1/8 1/10 540 550 F540 3650 3660 Motor, Red

heatsink conforms to the motor perfectly, no visible gaps which is important for heat dissipation. I dont find the wire protector necessary for my application so I removed it. my PRO4 SC10 runs cooler now.

I've not experienced a better fan in this category.It doesn't get stuck.The metal casing helps dissipate heat.This thing is Gem.I'm not affiliated or associated with Steve Vai.My loyalty is to Tom Scholz of Boston.

Awesome little heatsink and fan for my Rival MT10, running the Reedy 540-SL4 3300kv brushless motor. I upgraded from the stock 12t pinion gear to a 16t for more speed. Essentially, the motor's overheat protection will kick in and shut it off to prevent damage. Slapped this product on there and seems to be doing a great job. Haven't had a full battery run with it yet, but it is definitely keeping the motor cool. It fit somewhat snugly on my 36mm motor, though it slid off during bashing so I put on a ziptie to keep it in place. Only con is that the fan sounds a little rattly/raspy, but functions perfect so doesn't bother me.

Works perfectly on my traxxas slash. Last fan I tried wouldn't keep an ice cube cool on a cold day but these things are wonderful. Much better than the other brands.

The media could not be loaded. This fan seems very powerful. It definitely moves more air than the stock Arrma one did. The housing appears solid and it was super easy to install. One downside is the power cord. It looks and feels a little cheap. It is not coiled like in the picture and the red and black wires are not paired so it looks a little messy.

I recently purchased two of these fans and can’t comment on their durability but I’m very happy with their appearance and the amount of air they blow on the motors. These fans are keeping my motors very cool and in fact they are keeping the motors the coolest they have ever been. The fact that the fan is only held onto the motor heat sink with two screws and not four screws because the holes on the heat sink were not drilled correctly is not a problem for me. The fan does make excessive noise and that is also not a problem for me. That’s why I had to remove two stars from my rating. I’ll give my durability review at a later date when I have been using them for a while.

I use these on my OG emaxx. They move a lot of air. However they have a huge power drain on NIMH batteries so I will install them using a different battery source apart from the batteries that power the truck. They look and have a couple different color options. Not sure why they only have two screws on the fan gard? But it doesn't seem to affect anything.
