CSE011-0140-00 30mm Fan

The Castle Creations 30mm Fan (CSE011-0140-00) is a direct replacement cooling fan designed to keep your ESC running at optimal temperatures under heavy load.

It is a compact 30mm high-speed cooling fan used on compatible Castle ESCs such as the Sidewinder 4 and Copperhead 10. The fan helps pull heat away from the ESC’s internal components, improving efficiency, performance consistency, and overall reliability during high current draw or aggressive driving conditions.

Built as an OEM replacement part, it mounts directly to the ESC housing using standard hardware and plugs into the ESC’s fan port for simple installation. It is especially useful for off-road, bashing, and racing setups where heat management is critical for maintaining performance and preventing thermal shutdowns.
