About this part

The ProTek RC 35x35x10mm Aluminum High Speed HV Cooling Fan is a great option to keep your ESC and motor temps in check. The fan is a true 2S HV component that has been built to last with dual ball bearings and machined aluminum case. The case allows cooler operation of the fan motor, while also adding strength to the assembly, helping to protect the fan blades in the event of a crash. 

A pre-wired 30mm long 2 pin JST connector is used for connection, and we include a 170mm long JST/JR adapter plug that allows you to connect the fan directly to the receiver or another source of power. The fan is ideal to keep ESC's or motors cool, and can be mounted to an ESC that is compatible with a 35mm fan, directly to the chassis with double side tape, or to the motor using an optional 35mm fan mount (not included).

NOTE: This fan should be installed at least 5mm away from the motor to allow sufficient air flow and prevent magnet interference. 

Features:

  • 35mm aluminum cooling fan
  • Ideal for ESC and motor applications
  • Aluminum casing helps protect the fan blades
  • Compatible with 2S HV LiPo systems (8.75V max)
  • Anodized black with silver chamferred edges

  • 2 pin JST connector and included extension for easy installation

Awesome fans. Put 2 in the Maxx and they fit just like the originals. No need to switch wires around on the connector as they are the correct way. Whenever I need another fan I would buy more of these.

I purchased one of these for my x-maxx esc but now I'm ordering two more for the double fan motor mount. These fans are not quiet but they move a lot of air!!!

What reviewers say

Reviewers widely report that these 35x35x10mm aluminum fans fit stock mounts on Traxxas Maxx, X-Maxx and similar ESCs and motors as a drop-in replacement, and that they move substantially more air than stock plastic or cheap fans, lowering temperatures. Several note they are louder than stock, and a few mention blade cracking or fans working loose on the rotor. One reviewer reports fans burning out after several months across multiple ARRMA 6S cars, then a revised review says the seller resolved the issue. Most reviews are five-star verified purchases, with the single low rating being the burnout report.

  • + Drop-in fit for stock mounts
  • + Moves a lot of air
  • + Cooler temperatures than stock fans
  • + Holds up to bashing
  • − Louder than stock fans
  • − Blades prone to cracking
  • − Fan may work loose on rotor
  • − Isolated report of burnout
