About this part

The ProTek RC 30x30x10mm Aluminum High Speed HV Cooling Fan is a great option to keep your ESC and motor temps in check. The fan features a machined aluminum case that helps to dissipate heat, allowing cooler operation of the fan motor at high voltage specs. Plus the aluminum frame work adds strength to the assembly, helping protect the fan blades in the event of a crash.  

The fan is a true 2S HV component, that has been built to last with dual ball bearings, and pre-wired 30mm long 2 pin JST connector. Plus, we include a 200mm long adapter plug that allows you to connect the fan directly to the receiver or another source of power. The fan can be mounted directly to the chassis with double side tape, or by using an optional 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: 

  • 30mm aluminum cooling fan
  • Ideal for ESC and motor applications
  • Aluminum casing helps protect the fan blades

Jarrett MaltryVerified owneron ProTek RC 30x30x10mm Aluminum High Speed HV Cooling Fan (Blue/Black)

These things are tough! (And much harder to stall than stock fans!). I noticed on my DB pro the esc fan is… actually just a joke. I ran it through grass for 5 minutes, went to check temps, temps were OFF THE CHARTS, then I realized there was a SINGLE blade of grass that stopped the esc fan which made everything into an inferno.. very dangerous situation for electronics when a fan unexpectedly stops! . With these fans you won’t have a problem with that ?. I have two l my e revo 2.0 motor and those things take ABUSE. Everytime I land on the roof or flip it the body bends and smashes the frames of the fans and they still haven’t broken in 2 years. The frames have gouges and scratches all over them but they run like a tap, can’t recommend these more for a motor fan or esc fan. Especially because most of my RCs simply can’t fit a Game changer RC typhoon fan!

Keeping this review short & sweet. I have a Traxxas Slash Ultimate with the VXL-3S motor/ESC fan. Without any fans my motor reaches temps up to 180+ degrees. With the Traxxas shroud fan my motor reaches temps up to about 130 degrees. With the ProTek fan my motor went up to 86 degrees after 3 hours of playtime on a 3S battery. Pretty damn sweet and worth less than the Traxxas fan. 10/10 recommend.

Pete DeVrieson ProTek RC 30x30x10mm Aluminum High Speed HV Cooling Fan (Blue/Black)

I picked up the blue version for my new Tekno EB410.2 as I have a few bits of blue aluminum, and the black one for my TLR 22 5.0 Elite as the black and milled silver aluminum on the servo matches my Hobbywing XR10 Pro esc/V10 G3 7.5t motor, as well as the black and milled silver aluminum on my Protek 160t servo perfectly plus all of the stock aluminum on the kit. (Steering bellcranks/ackerman, C and D blocks' rear camber link mount, rear hubs etc. It all looks so good together you would think that one company built it all to go together. As far as the performance of the fans, they are awesome. I want to lower the BEC voltage down a ways from 7.4 to slow the fans down some to see how much quieter they get. Having these plus the stock fans on the XR10's both cars are super loud once they are on and even the servo torque levels at 6v is plenty for both the cars... pretty sure i dont need 275 in/oz in 1/10 buggies...

2 out of my five I purchased the past year have quit working. Price is the only reason I might buy another one

What reviewers say

Reviewers broadly praise the fan's airflow and cooling performance, with several reporting lower motor and ESC temperatures on 3S and high-capacity setups. Build quality and aluminum construction are frequently described as durable and good-looking, and some note it holds up well to impacts. Noise is a recurring complaint, especially at higher voltage, and some reviewers say it is heavier than plastic fans. A few reports describe fans failing after several races or within months, and one reviewer warns that debris or a stopped blade can quickly overheat electronics. Several reviews mention the blue/black variant specifically and note it matches other blue or black aluminum parts.

  • + Strong airflow and cooling
  • + Durable aluminum build
  • + Lowers motor and ESC temperatures
  • + Good looks and color options
  • − Loud at higher voltage
  • − Heavier than plastic fans
  • − Some fans fail after limited use
  • − Debris or stalls can overheat electronics
