Overview
The Traxxas Velineon Cooling Fan (TRX3340) is an essential accessory for RC enthusiasts who demand maximum performance from their brushless ESC systems. Whether you're running a high-speed Traxxas Slash, Rustler, Stampede or other VXL-equipped RC car in the UK, this dedicated cooling fan significantly extends your run times and maintains consistent power delivery during extended operation. Designed specifically for the Velineon VXL-3s, VXL-4s and BL-2s speed controls, this cooling fan is an invaluable investment for anyone serious about protecting their expensive ESC from thermal throttling and overheating.
RC car racing and bashing can generate substantial heat within your electronic speed controller, particularly during hot summer months or when pushing your vehicle to its limits on the track or off-road terrain. The Velineon Accessory Cooling Fan addresses this critical challenge by actively drawing air across the ESC's heatsink, maintaining optimal operating temperatures and ensuring your brushless RC car performs at peak efficiency throughout your entire session. This is especially important for competitive racers and serious hobbyists who cannot afford power loss due to thermal management issues.
Installation is incredibly straightforward, making this cooling solution accessible to beginners and experienced RC car enthusiasts alike. The fan features integrated wire routing with a dedicated connector clip, eliminating messy wiring while maintaining a professional appearance. Simply plug the fan into your ESC's accessory power connector and securely clip it onto the heatsink—no soldering, modifications or complex installation steps required. This plug-and-play design means you can upgrade your thermal management in minutes.
Key Features
- Active ESC Cooling System — The Velineon Cooling Fan actively draws air through the ESC heatsink during operation, significantly reducing component temperatures compared to passive cooling alone, which means your electronic speed controller maintains optimal performance throughout extended running sessions without thermal throttling.
- Compatible with Multiple VXL Speed Controllers — This cooling fan works seamlessly with the Velineon VXL-3s, VXL-4s and BL-2s electronic speed controls, providing broad compatibility across a range of Traxxas brushless RC vehicles including the Slash, Rustler, Stampede and numerous other models available in the UK market.
- Secure Mounting Design — The fan securely clips directly onto the ESC heatsink without requiring any modification to your RC car's chassis or electronics, ensuring reliable operation even during aggressive off-road bashing or high-speed racing where vibration and impact could dislodge inferior mounting solutions.
- Integrated Connector Clip — Wires are neatly routed and organised thanks to the integrated connector clip system, which keeps your installation tidy whilst also protecting the wiring from damage and ensuring the connector remains firmly in place during aggressive driving conditions.
- Accessory Power Connector — The fan connects directly to your ESC's dedicated accessory power connector, meaning no soldering or permanent modifications are required and you can install or remove the fan in seconds without any risk of damage to your speed controller.
- Automatic Operation — The cooling fan powers on automatically whenever your ESC is active, requiring zero additional control or setup once installation is complete, making this one of the most hassle-free cooling upgrades available for brushless RC cars in the UK.
- Proven Reliability — Users consistently report that the Velineon Cooling Fan delivers surprising cooling capacity despite its compact size, with many reporting they no longer experience thermal shutdown issues even during extended sessions in hot weather or with high-capacity LiPo batteries.
Technical Performance
The Traxxas Velineon Cooling Fan represents a significant engineering advancement in thermal management for brushless RC cars. Built with quality materials and precision engineering, this accessory fan is specifically engineered to work in harmony with Traxxas's acclaimed Velineon brushless ESC range. The fan operates silently and efficiently, drawing minimal current from your ESC's accessory power connector whilst delivering substantial cooling benefits. Customer feedback from RC enthusiasts across the United Kingdom consistently demonstrates that this cooling solution prevents the thermal throttling that can severely limit performance during extended high-demand sessions. The compact design ensures the fan does not interfere with battery expansion kits or other common RC car accessories, though some users with very tight chassis configurations may need to consider space requirements. The integrated connector clip system not only maintains a professional appearance but also eliminates the risk of loose wiring causing electrical issues. Whether you're running 2S, 3S or 4S LiPo batteries with your Velineon ESC, this cooling fan helps maintain safe operating temperatures and ensures maximum power delivery is available throughout your run time.

Frequently Asked Questions
- Is the Traxxas Velineon Cooling Fan compatible with my RC car? — This cooling fan is specifically designed for Traxxas vehicles equipped with Velineon VXL-3s, VXL-4s or BL-2s electronic speed controllers. Compatible models include the Rustler Ultimate VXL 4x4, Slash Ultimate 4x4 VXL, Slash VXL-3S, Slash Extreme HD VXL, Stampede 4X4 HD VXL and many other Traxxas brushless RC cars. Check your ESC model to confirm compatibility before purchasing.
- How difficult is it to install the Velineon Cooling Fan? — Installation is extremely straightforward and takes only seconds. Simply locate your ESC's accessory power connector, plug the fan's connector into it, and clip the fan body onto the ESC's heatsink. No soldering, wiring modifications or tools are required, making this accessible even to complete beginners who are new to RC car customisation.
- Will the cooling fan help my ESC run cooler during extended sessions? — Yes, absolutely. Multiple users report that the Velineon Cooling Fan delivers surprising cooling capacity and effectively prevents thermal throttling during extended driving sessions. Many RC enthusiasts state they no longer experience overheating shutdowns after installing this fan, particularly when running high-capacity LiPo batteries in warm weather conditions.
- Does the cooling fan require any separate power source or battery? — No, the cooling fan draws its power directly from your ESC's built-in accessory power connector. This means it powers on automatically whenever your ESC is active and requires no additional battery, charging or control setup whatsoever.
- What is the difference between this cooling fan and passive heatsink design? — The Velineon Cooling Fan provides active forced-air cooling, which is significantly more effective than passive cooling alone. Whilst passive heatsinks rely on ambient air circulation, this active cooling fan actively draws air across the heatsink fins, maintaining substantially lower ESC temperatures even during intensive driving, high ambient temperatures or when using larger capacity batteries that generate more heat.
- Is the Velineon Cooling Fan waterproof? — The cooling fan is not fully waterproof, though users report it has survived water splash and exposure during casual bashings. If you plan to use your RC car in wet conditions, exercise caution around the fan area to minimise water ingress into the ESC electrical connections.
- Will the cooling fan fit with a battery expansion kit? — In most installations the cooling fan fits without issues. However, if your RC car uses a battery expansion kit, ensure you have adequate clearance above the ESC, as the fan height may restrict airflow or physical fitment in very compact setups. Some users have reported needing to reposition components in tightly configured chassis.
