ARRMA Mini Kraton 3S 30x10mm Cooling Fan MAKM018FAN by GPM  [MAKM018FAN]

30x10mm high-speed fan built for Mini Kraton 3S

This 30x10mm cooling fan is an RC-scale accessory designed for ARRMA Mini Kraton 3S platforms to control motor temperature and support steady brushless performance. The rotor is machined from 6061-T6 aluminum while the outer cover uses 7075-T6 alloy, giving a light but stiff metal construction suited to track and bash use.

Manufacturer electrical and mechanical data list a nominal speed of 20000 rpm ±20%, dual ball bearings, and a recommended operating voltage range of 5V–9V with a typical current draw near 0.6A. The fan can be connected directly to the receiver power bus; applying more than 9V risks motor damage and must be avoided.

Installation is straightforward for hobbyists familiar with small-scale hardware: the unit arrives pre-assembled and mounts using the supplied Grade 12.9 black flat head screws. Apply a thread-locking compound to metal-to-metal fasteners to reduce loosening under vibration. Power may be taken from the receiver or from a regulated switched BEC while observing the voltage limit above.

The fan helps stabilise motor temperatures during repeated short runs or heavy acceleration, which can preserve consistent ESC and motor response without changing core gearing or motor timing. Ensure there is adequate clearance for airflow around the heatsink and keep wires and suspension parts clear of the rotor.

A compact metal-bodied option for ARRMA Mini Kraton 3S setups that need steady airflow over a motor heatsink; fit with the supplied hardware and keep voltage within the 9V limit for safe operation.
