Race focused cooling for 280/300 motor setups

Engineered for competitive use, the 3Racing Motor Heat Sink with Fan in purple provides focused cooling for 280 and 300 size motors. The aluminium sink conducts heat away from the can while the integrated fan forces air across critical areas, aiding consistent performance in race conditions.

Technical advantages of the 3Racing heat sink

  • Compatibility: Tailored for common 280 and 300 motor diameters used in club and regional racing
  • Material: CNC-like aluminium body to maximise heat transfer and durability
  • Color: Purple finish for quick visual identification in pit boxes
  • Functionality: Direct air flow from the fan enhances cooling at high RPMs

How does this sink affect motor thermal resistance?

The aluminium body lowers thermal resistance by increasing surface area and pairing that with forced convection from the fan, reducing steady state temperature under load.

What mounting considerations should racers use?

Ensure secure clamping to the motor can without distorting the endbell; confirm axial clearance for the fan and avoid contact with pinion or chassis components.

Are there tuning benefits to lower motor temps?

Lower motor temperatures preserve magnet and winding performance, enabling more consistent power delivery and predictable timing when tuning for race conditions.

Can the fan be powered from the receiver or ESC?

Power from the receiver may be acceptable for low current fans, but for reliability use a regulated supply or auxiliary BEC to avoid stressing the receiver circuit during events.
