DKKY RC Motor Cooling Fan Heatsink – Up to 20,000 RPM, 47-51mm Adjustable Mount for 1717/4985 Motors

Enhanced Cooling for Your RC Motors

Meet the DKKY RC Motor Cooling Fan Heatsink, a purpose-built solution that combines precision machining with practical cooling performance. Crafted from high-quality material and CNC machined for smooth edges and reliable durability, this unit is designed to dissipate heat efficiently during demanding drives. The result is steadier motor performance and a cooler, more consistent ride across sessions.

The fan is engineered to deliver up to around 20,000 RPM, creating a steady flow of air that helps keep motor temperatures in check even during extended bashing or fast laps. A cooler motor can translate to more consistent throttle response and reduced risk of heat-related performance drop, giving you a potential edge on the track or on rugged off-road runs.

Flexible fit for diverse setups

With an adjustable 47-51 mm mount, this heatsink fits a wide range of 1/8 and 1/5 scale RC cars, including popular brushless and brushed motors. It is compatible with motors like 4985 and 1717 families, making it a versatile upgrade for ARRMA, Infraction, Felony, Limitless, and Axial platforms.

• 47-51 mm adjustable diameter for a snug, secure fit
• Compatible with 4985 and 1717 style motors for varied builds

Easy power, smart safety

Powered by an 8-12V supply, the fan can be wired through the included 2S or 3S LiPo balance connector. A built-in circuit breaker adds a safety, user-activated shutoff option when the fan is not in use, helping protect your electronics during storage or transport. At 12V, the unit draws about 1A, balancing performance with efficiency.

• Operates on 8-12V power, compatible with common LiPo packs
• Integrated circuit breaker provides a safe shutoff option

What you get and how it helps

The package includes the RC motor cooling fan with the adjustable mount and a screw set, giving you a ready-to-install upgrade for compatible RC cars. While not a guarantee of results, users may experience improved airflow around the motor, potentially helping to maintain performance during intense runs and hot environments.
