Description

40x40mm Cooling Fan Upgrade Adapter – Replaces Stock Fans
for ARRMA Felony ESC & Motor

This 3D-printed adapter is designed to replace the small, weak factory-installed cooling fans on the ARRMA Felony ESC and motor, allowing you to upgrade to a much more powerful standard 40x40mm fan.

The original stock fans are undersized and provide limited airflow. By replacing them with a 40x40mm fan, this adapter delivers significantly improved cooling performance, better heat dissipation, and more stable temperatures under heavy load.

🔧 Key Benefits

  • Replaces small, weak factory fans
  • Upgrades cooling system to a powerful 40x40mm fan
  • Designed specifically for ARRMA Felony
  • Greatly improves ESC and motor cooling
  • Helps prevent overheating and thermal throttling
  • Simple, clean, bolt-on installation

🖨️ 3D Printing Notes

  • Recommended materials: PLA+ / PETG / ABS
  • No supports required
  • Print flat on the bed
  • Compatible with most standard 40x40mm RC fans

🚗 Ideal For

  • Drivers dissatisfied with factory cooling
  • Speed runs and high-power setups
  • Long sessions and hot weather driving

If you want to eliminate the limitations of the small stock fans, this adapter provides a clean and effective upgrade to full-size 40x40mm cooling.
