Check the 2022 Edition of the Rocket Airsoft High Torque Motor available at Airsoft Atlanta which comes with a fan or no fan... "New Rocket Airsoft High Torque Motor (2022 Edition) - newly upgraded high strength stator magnet which greatly increases torque. We highly recommend this motor if you are upgrading your spring or installing a high speed gear set. Or, if your stock motor is getting old or generating too much heat, this motor is a great replacement. It is a low cost equivalent of most other ultra-torque motors. Check axle length on your gun to verify the type before ordering.  Most common guns use the long, but the short is useful on some airsoft guns too.

Comes with fan or without fan, and with or without the CNC bottom base.  Long and short style motor lengths."
