• The  40x40x10mm 12V DC Cooling Fan is a compact, high-performance brushless axial fan offered in two popular blade variations to suit different cooling needs. The 7-blade version provides smooth, balanced airflow ideal for general ventilation and open-air cooling, while the 9-blade version delivers higher static pressure for pushing air through restricted spaces like heatsinks, dense enclosures, or filtered intakes – making it great for focused component cooling.
• Running on standard 12V DC with a reliable brushless motor, this fan ensures extended durability, minimal power consumption, and quieter performance than brushed alternatives. Its slim 10mm thickness fits perfectly in space-limited applications such as 3D printer part cooling/hotend setups, network routers, DVR boxes, audio amplifiers, LED drivers, CCTV housings, and various DIY electronics projects.
• The durable black plastic frame includes four mounting holes for easy screw installation, and the low-noise operation keeps your setup peaceful. Whether you need versatile airflow or targeted pressure, choose the right blade count for your project – both deliver excellent value and reliable cooling from .
• Sold as 1 piece – ideal for replacements, testing, or small upgrades.
