Frequently Asked Questions

• What size motors does this fan unit fit? — The RC Overhaul Motor Fan Unit is designed with an adjustable clamp mount system that accommodates motors with outer diameters between 38–42mm. This covers the vast majority of popular brushless and brushed motors used in modern RC cars, buggies, trucks and crawlers available in the UK. If you're unsure whether your specific motor falls within this range, we recommend measuring your motor's outer diameter or contacting our team for assistance.
• How does the temperature sensor work? — The integrated inline temperature sensor continuously monitors your motor temperature. When heat reaches 35 degrees Celsius or higher, the sensor automatically activates the high-powered fan unit to provide active cooling. Once temperatures drop below this threshold, the fan cycles off, helping to preserve battery power during cooler running conditions. This automatic operation means you can focus on driving without worrying about manual temperature management.
• Will this fan unit work with my ready to run RC car? — Yes, provided your vehicle uses a motor with an outer diameter between 38–42mm and has sufficient space for the compact clamp mount near the motor. Most popular ready to run RC cars and trucks from brands available in the UK do use motors within this size range. The space-saving clamp design is specifically engineered for situations where installation space is tight, making it ideal for many standard RC vehicle builds.
• What are the benefits of keeping my motor cooler? — Keeping your motor cooler delivers significant advantages for your RC experience. Cooler motors maintain higher torque output and performance consistency throughout your running sessions, meaning you'll get the same punch from the first lap to the last. Extended motor lifespan is another major benefit—thermal stress causes gradual degradation of internal motor components, and active cooling dramatically slows this process. Additionally, cooler motors generally experience less voltage sag and maintain better efficiency, which can translate to longer overall run times per battery charge.
• Is this suitable for competitive RC racing? — Absolutely. Competitive RC racers often rely on active motor cooling to maintain consistent performance through extended practice sessions and race heats. The automatic temperature sensor ensures your motor stays within the optimal operating range, helping you maintain competitive pace without the distraction of manual cooling management. Many serious competitors in the UK RC racing community use similar cooling solutions as part of their race setup.
• What space does this fan unit require? — The RC Overhaul Motor Fan Unit is specifically designed as a space-saving solution. The compact clamp mount and 40mm fan unit are engineered to fit in tight installations where space around your motor is limited. However, you should ensure sufficient clearance around your motor for the fan unit itself—approximately 50–60mm in height and 50mm in width depending on mounting orientation. We recommend measuring your available space before purchase.
• Can I use this with any battery type? — Yes, the motor fan unit itself is powered by your main drive battery through the ESC (electronic speed controller), so it works with any battery chemistry compatible with your vehicle—whether LiPo, NiMH, or other types. The fan unit will automatically cool your motor whenever it's running, regardless of battery type.
• How does this compare to passive heatsinks? — Whilst passive heatsinks (non-powered cooling fins) are lightweight and reliable, they rely on ambient air circulation to dissipate heat. The RC Overhaul Motor Fan Unit provides active, powered cooling that forces airflow directly onto your motor. This delivers superior cooling performance, particularly during intense running sessions, extended races, or aggressive bashing where motors generate significant heat. Active cooling is particularly valuable if you're pushing your motor hard or running in warm conditions.
