Competition Cooling Overview

The 3RACING 3RAC-MHS007/RE Extended Motor Heat Sink with Fan is targeted at racers who need consistent thermal control on 540 motors. Its extended fin geometry and active airflow reduce surface temperature variation during repeated runs.

Technical Highlights

  • Compatibility: Engineered for the 540 form factor to ensure correct seating and thermal transfer to the motor can.
  • Material: Durable construction selected to endure regular race use and handling.
  • Design: Longer heatsink body with integrated fan enhances convective cooling for improved repeatable performance.
  • Color: Red finish makes it easy to identify upgrade components in a race build.

Setup and Tuning Notes

When optimising a race car, this heat sink aids in stabilising motor temperature between runs. Check mounting clearance and fan wiring during setup to preserve clean airflow and minimise interference with sensor or power leads.

How does the 3RAC-MHS007/RE help during back to back runs?

The extended surface area and fan reduce heat soak between runs, helping keep RPM and power delivery more consistent across successive heats.

Any fitment tips for tight race chassis?

Verify clearance around the motor and plan fan wiring to avoid contact with suspension or sensor cables; minor bracket adjustment may be required on compact layouts.

Is this a recommended upgrade for tuned motors?

For tuned or high duty cycle motors, the added cooling can reduce thermal related performance drift, making it a sensible step in performance builds.
