Evercool 40x40x20 2Ball (5000 RPM) Fan EC4020M12BA

Evercool EC4020M12BA is a small 40 mm fan with 2 Ball bearings, made for places where serious cooling is needed in minimal space – mini PCs, network equipment, routers, power supplies, 3D printers, and other devices. It operates at 5000 RPM, which for this size means stable airflow and better heat dissipation compared to cheap no-name options. Despite the high speeds, the noise is below 21 dBA, so it will not become an annoying “whistling” noise source in the system. It is powered by standard 12 V and comes with a 3 Pin connector for easy connection to a motherboard or controller.

What you get

With a real airflow of 4.17 CFM / 7.08 m3/h, this fan is a good choice for actively cooling small radiators, chips, or closed cases with poor natural ventilation. The 2 Ball Bearing bearings perform better in horizontal and vertical positions and are more reliable in long continuous operation compared to cheap sleeve bearings. With a consumption of only 0.96 W, you can leave it running 24/7 without worrying about overloading the power supply or excessive costs. The declared MTBF 50000 hours (several years of continuous operation) is a strong plus if the fan goes into a device that you do not want to frequently access for replacement. With a 3 Pin connector, you can connect it directly to a motherboard or fan header on a controller and, if necessary, use voltage control for speed management.

• Compact form factor 40 x 40 x 20 mm, suitable for mini cases, network devices, power supplies, and tight spaces.
• High speeds of 5000 RPM, providing noticeable airflow for effective cooling of small radiators and components.
• Airflow of 4.17 CFM / 7.08 m3/h, optimized for targeted cooling of hot spots where there is no room for a larger fan.
• Low noise level below 21 dBA, so the fan remains relatively quiet even at maximum speeds.
• Reliable 2 Ball Bearing bearing, more resistant to long operation and various mounting positions compared to standard sleeve bearings.
• Low consumption of 0.96 W at standard 12 V power supply, making it suitable for devices with limited energy budgets.
• Long service life with MTBF 50000 hours, suitable for 24/7 systems, and convenient 3 Pin connector for easy connection.

Who it is suitable for

This fan is suitable if you are looking for compact and reliable cooling for small cases, network devices, NAS, mini servers, 3D printers, or specialized electronics. It is also a good choice for replacing an OEM fan in a power supply or other equipment of the same size. It is not suitable if you are chasing high airflow for a large PC case – for that, you need larger fans.

The combination of size 40 mm, 2 Ball bearings, 5000 RPM, and low noise below 21 dBA makes Evercool EC4020M12BA a practical, “install and forget” option for small but critically important cooling points in your system.
