Evercool 40x40x20 EL Bearing (5000 RPM) EC4020M12EA

Evercool 40x40x20 EL Bearing (5000 RPM) EC4020M12EA is a small 40 mm fan designed for compact systems, networking equipment, power supplies, NAS cases, or any devices with limited space. With dimensions of 40 x 40 x 20 mm and up to 5000 RPM, it focuses on stable airflow in a small form factor. It operates on the standard 12 V for PC/electronics, with a 3-pin connector for easy connection to a motherboard or controller. Add a low noise level below 21 dBA and an EL Bearing, and you get a balanced solution between cooling and silence.

What you get

At speeds of up to 5000 RPM, the fan provides an airflow of 4.17 CFM (7.08 m3/h), which is sufficient for cooling radiators and small enclosed volumes where air would otherwise stagnate. The consumption is only 0.96 W, so you can use it in more power-sensitive devices without overloading the power supply. The EL Bearing and declared MTBF of 40000 hours mean durability in 24/7 operation, typical for networking and industrial equipment. The noise level below 21 dBA helps keep the acoustics under control, especially if you mount several such fans in one case.

• Compact size of 40 mm, suitable for small cases, power supplies, routers, and custom projects.
• Physical size of 40 x 40 x 20 mm, providing slightly greater thickness for better airflow compared to standard 10 mm models.
• Speeds of up to 5000 RPM, providing stable cooling in confined spaces.
• Airflow of 4.17 CFM / 7.08 m3/h, suitable for targeted cooling of chips, VRMs, RAM, SSDs, or small radiators.
• Low noise level below 21 dBA, which helps keep the system quieter even at higher speeds.
• Operating voltage of 12 V and 3-pin connector for easy integration into motherboards and fan controllers.
• Low consumption of 0.96 W and MTBF of 40000 hours for long-term, economical, and reliable operation.

Who it is suitable for

This fan is suitable if you are looking for a small 40 mm cooler for networking equipment, NAS, small SFF/ITX cases, or for specific components in a PC that need directed airflow. It is also convenient for DIY projects, 3D printers, modifying power supplies, and other devices with 12 V power and a 3-pin connection. It is not the optimal choice if your goal is primary airflow for a large PC case – there you need larger fans (120/140 mm).

The combination of compact size, 5000 RPM, low consumption, and EL Bearing makes this Evercool 40x40x20 a reasonable choice when you need a reliable small fan that runs long and quietly in a limited space.
