Technical Performance

The Traxxas TRX3474 dual cooling fan kit represents the manufacturer's engineering solution to one of the most critical challenges in high-performance RC vehicle operation: thermal management of powerful brushless motors. When running a Velineon 1200XL or 1600XL motor at full throttle, internal temperatures can climb rapidly, causing performance degradation and potentially shortening motor lifespan. This kit addresses that challenge through dual-fan architecture that creates substantial air circulation over the motor. The shroud design is aerodynamically optimised to channel airflow directly across the motor windings and permanent magnets where cooling is most needed. Built from durable materials engineered to withstand the extreme vibration environment of high-powered RC vehicles, the fans operate on a simple principle: they're powered through your receiver's Channel 5 port and activate automatically whenever your ESC receives power. This means your cooling system runs throughout every driving session, delivering consistent thermal management whether you're running at low speed during technical courses or wide-open throttle on open terrain. The integration with the 3362 aluminium heat sink creates a complete thermal pathway: the sink absorbs heat from the motor case, the dual fans force air through and across the aluminium fins, and the shroud ensures maximum airflow efficiency. For serious RC enthusiasts operating high-output Velineon motors in the UK and beyond, this cooling system is the difference between extended run times with consistent power and performance degradation due to thermal throttling. Installation involves standard RC maintenance skills—removing the motor, mounting the heat sink, securing the fans with coarse-thread screws (which grip between the heatsink fins without requiring pre-drilled holes), and routing the wire harness through your receiver box. The result is factory-quality cooling that allows you to push your X-Maxx, X-Monster, or XRT model to its true performance potential.

Frequently Asked Questions

• What is the benefit of dual cooling fans versus a single fan? — Dual fans create significantly superior air circulation and heat dissipation. Two fans working together generate more cubic feet per minute of airflow and create better pressure dynamics that force air through the heatsink fins more effectively than a single fan could achieve, resulting in lower overall motor temperatures and more consistent performance throughout extended driving sessions.
• Which Traxxas models are compatible with this cooling fan kit? — This kit is designed for Traxxas vehicles equipped with Velineon 1200XL or 1600XL motors. Primary compatibility includes the X-Maxx Belted 4WD Brushless RTR (in all colour variants), X-Maxx Ultimate models, X-Monster Chassis, and XRT VXL-8S models (in all colour options). Direct installation without modifications is available for Hoss 4X4 VXL; other compatible models may require simple fan shroud trimming.
• Do I need the 3362 heat sink to use this cooling fan kit? — Yes, the dual cooling fans and shroud are designed to fit over the Traxxas 3362 aluminium heat sink. The heat sink is a separate component that you'll need to obtain and install on your motor before mounting the dual fans; however, many users already have the 3362 heat sink installed on their Velineon motors, so you may already have this critical component on hand.
• How difficult is the installation process? — Installation is straightforward and accessible to RC enthusiasts with basic mechanical skills. Traxxas estimates 15 to 20 minutes of bench time is required. You'll need only a 2 mm and 2.5 mm screwdriver to remove the motor, install the heat sink, mount the fans, and connect the wire harness to your receiver. A ball-end driver makes the job easier by allowing you to access screws at awkward angles, but it's not essential.
• Will this fan kit work with other Traxxas motors or brands? — No, this kit is specifically engineered for Traxxas Velineon 1200XL and 1600XL motors and integrates with the Traxxas 3362 heat sink. Using it with other motor types or brands would compromise fit and cooling effectiveness. Traxxas manufactures other cooling solutions for different motor types, such as the 3458 heat sink for 3500 and 540XL brushless motors.
• How does the fan activate and deactivate? — The dual fans are controlled through your receiver's Channel 5 battery port. They automatically activate whenever your speed control receives power and will remain running continuously as long as your vehicle is powered up. This automatic activation means you get cooling exactly when you need it—during every driving session—without requiring manual switches or separate control systems.
• Will I need to trim the fan shroud on my model? — This depends on your specific vehicle. If you're installing the fans on a Hoss 4X4 VXL, no trimming is required and the shroud fits perfectly as-is. For Rustler 4X4 VXL, Slash 4X4 VXL, Stampede 4X4 VXL, and other compatible models, you'll need to trim away the step-down portion of the shroud using side cutters or flush cutters. This is a simple modification that takes just a few minutes, and you can further smooth the edges with a rotary tool and sanding drum if desired for a factory appearance.
• What tools do I need to perform the installation? — Essential tools are a 2 mm and 2.5 mm screwdriver. A ball-end hex driver makes the job easier but isn't required. If you need to trim the shroud on your model, side cutters or flush cutters are ideal; a rotary tool with sanding drum is optional for finishing trimmed edges. Most RC enthusiasts already have these basic tools in their workshop.
• Can this fan kit be installed on my existing setup, or do I need a new heat sink too? — If you already have the Traxxas 3362 aluminium heat sink installed on your Velineon motor, you can simply add this dual fan kit directly to your existing setup. If you don't currently have the 3362 heat sink, you'll need to purchase it separately, as the fans are designed to mount directly to this specific heat sink model.
• How much cooler will my motor run with this cooling system? — While exact temperature reductions depend on ambient conditions and driving intensity, users consistently report noticeably lower motor temperatures—typically 10-20 degrees Celsius cooler than without cooling fans—which translates directly to longer effective run times, more consistent power delivery, and extended motor lifespan. Cooler operation means your Velineon 1200XL or 1600XL motor maintains peak performance throughout your entire driving session rather than thermal throttling as temperatures rise.
• Is this suitable for casual weekend bashers or only serious competitors? — This cooling kit is valuable for any RC enthusiast running Velineon 1200XL or 1600XL motors, whether you're a casual weekend basher enjoying your X-Maxx or a competitive driver pushing your XRT to the limit. Cooler motors deliver better performance and last longer, making this an investment that benefits any user. However, if you only run your vehicle for short sessions in cool weather, you may see less dramatic benefits than users who run extended sessions or in warm climates.
• Will this affect the appearance of my RC vehicle? — The dual fan shroud is a functional component visible on your vehicle, similar in appearance to other high-performance RC upgrades. On Hoss 4X4 VXL models, it installs without modification and maintains a clean look. On other models where shroud trimming is required, you can achieve a professional, factory-like appearance by using a rotary tool to smooth the trimmed edges. Most RC enthusiasts view performance-enhancing cooling systems as desirable upgrades that enhance their vehicle's appearance by highlighting its high-performance credentials.
