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

Performance cooling for aggressive bashing and sprint runs

This 30x10mm cooling fan is an accessory intended for ARRMA Mini Kraton 3S vehicles to help maintain motor temperature under hard use. The rotor uses 6061-T6 aluminum and the outer cover is fashioned from 7075-T6 alloy, offering a durable, lightweight metal construction suitable for aggressive driving.

Electrical specs provided by the manufacturer indicate a nominal speed of 20000 rpm ±20%, dual ball bearings, and operation across 5V–9V with an approximate current draw of 0.6A. The fan supports direct connection to the receiver power rail but must not be overdriven beyond 9V to avoid motor burnout.

Assembly is aimed at hobbyists comfortable with small hardware: the product ships pre-assembled and fits using the supplied Grade 12.9 black flat head screws. Use thread-lock on metal threads to limit loosening during high-vibration use. Power can be taken from the receiver or from a regulated switched BEC, following the voltage limits.

From a setup perspective the fan reduces temperature spikes during repeated acceleration bursts, keeping ESC and motor behavior more consistent without changing gearing or motor timing. Maintain adequate clearance for airflow and keep wires clear of the fan path.

A compact, metal fan option for ARRMA Mini Kraton 3S setups needing reliable airflow; fit with supplied hardware and respect the 9V maximum for safe operation.
