Cobra Racing’s Blue Motor Cooling Fan for Traxxas, Arrma & More

Active Motor Cooling for 1/10 & 1/8 Scale RC Vehicles
SEE FULL COMPATIBILITY LIST BELOW

High-performance RC vehicles generate heat — regardless of brand or platform. The Cobra Racing 36mm RC Motor Cooling Fan is engineered as a universal motor cooling solution designed to reduce operating temperatures across Traxxas, Arrma, and other 1/10 and 1/8 scale RC platforms.

Whether you’re bashing, racing, or running aggressive gearing in warm conditions, excessive motor heat leads to power fade, inefficiency, and premature wear. This fan system actively removes heat from the motor can to help maintain consistent performance and long-term reliability.

What This Motor Cooling Fan Does

The Cobra Racing 36mm RC Motor Cooling Fan reduces motor temperatures by actively pulling heat away from the motor can using a high-RPM fan paired with a 7075-T6 aluminum heatsink. By continuously moving air across the motor surface, it helps prevent overheating, power loss, and premature motor wear during hard driving.

Why Motor Cooling Matters

RC motors generate heat under load. When heat builds up faster than it can be dissipated, performance drops and components wear out more quickly. Common causes of overheating include:

• High gearing and speed-focused setups

• Larger or heavier tires

• Extended bashing sessions

• Warm ambient temperatures

• Limited airflow around the motor

Active cooling helps stabilize motor temperatures and allows your vehicle to maintain consistent performance run after run.

Engineering & Design

7075-T6 Aluminum Heatsink

The integrated heatsink is machined from 7075-T6 aluminum, chosen for its excellent thermal conductivity and high strength-to-weight ratio.

• Rapidly absorbs heat from the motor can

• Spoke-style fin design increases total surface area

• Proper spacing between fins allows airflow to pass through instead of trapping heat

This design spreads heat across a larger surface area so it can be removed efficiently.

High-RPM Active Cooling Fan

Mounted directly above the heatsink, the fan spins at 15,000 RPM, forcing cool air across the aluminum fins.

• Actively removes heat even at low vehicle speeds

• Prevents heat buildup during repeated acceleration

• Maintains cooling when natural airflow is limited

Together, the fan and heatsink function as a complete thermal management system.

Key Features

• 36mm universal motor fan design

• 7075-T6 aluminum heatsink for efficient heat transfer

• 15K RPM high-airflow fan

• Stainless steel fan guard for durability

• Compact and lightweight design

• Installs the same way as OEM motor hardware
