Race Oriented Cooling for 540 Motors

Engineered for tuning and track performance, the 3Racing Gold Extended Motor Heat Sink with Fan targets 540 motors to reduce thermal drift and maintain predictable power delivery. The fin geometry and fan airflow are chosen for efficient heat extraction under continuous load.

Performance Tuning and Thermal Control

Lower running temperatures help maintain consistent magnetic and winding properties, which is critical when refining gear ratios and timing for competitive setups. The robust gold finish improves wear resistance while keeping weight minimal.

Fitment and Integration for Tuners

The heat sink mounts cleanly to standard 540 cans and is compatible with common motor bracket arrangements, enabling quick integration into tuned builds. Proper seating and use of thermal interface material will optimise conduction and reduce thermal resistance.

How should I verify thermal contact after installation?

Run a brief test at moderate load and monitor motor temperature with an infrared gun or telemetry. Recheck mounting torque and interface material if readings are high.

Are there recommended fan voltages or controllers?

Use a low current, reliable fan rated for the supply you intend to use; PWM control can be used to reduce wear and manage noise during pit intervals.

Does the sink affect motor thermal equilibrium during back to back runs?

Yes, the active cooling helps limit progressive temperature rise between runs, which makes tuning repeatable and reduces variable motor behaviour from heat buildup.
