SKU CH-P306-7G6MK

A 4028 motor fan cools RC cars at 16000 RPM using 16 V and 3.8 W in a 40 by 40 by 28 mm frame

  • Efficient motor cooling with 16000 RPM airflow
  • Compact 40x40x28 mm footprint fits tight RC chassis
  • Low 3.8 W draw at 16 V extends battery run-time
  • New condition ensures reliable performance from first use

Compact cooling fan for RC motors

This 4028 fan measures 40 by 40 by 28 millimetres and runs on a 16 volt supply. It draws 3.8 watts while spinning at 16000 RPM to move air across small electric motors. The unit is new and intended for hobbyists who need focused airflow in tight chassis spaces.

Steady airflow under continuous load

At constant voltage the motor maintains its 16000 RPM rating without thermal throttling, so cooling performance stays consistent during long runs. The 3.8 watt draw remains stable, avoiding current spikes that could stress a compact speed controller. Builders who need variable speed or lower noise at reduced voltage should look elsewhere.
