Fan Evercool 40x40x28 2 ball bearing 12000rpm - EC4028HH12BA

Evercool EC4028HH12BA is a compact 40 mm fan aimed at situations where you have limited space but need serious airflow. It operates at up to 12000 RPM, which is a very high speed for this size, and uses a 2 Ball Bearing bearing for longer life under 24/7 load. It supports an 18.94 CFM airflow, which is solid for the 40 x 40 x 28 mm format. This makes it suitable for server coolers, networking equipment, power supplies, small cases, and various DIY projects.

What you get

With a thickness of 28 mm, this fan has a deeper profile compared to standard 10–20 mm fans, allowing it to push more air through dense radiators or narrow openings. With up to 18.94 CFM / 32.18 m3/h airflow, you can cool components with concentrated heat-generating elements – for example, VRM sections, miniature radiators, or small chassis. The 2 Ball Bearing system is more resilient at high speeds and horizontal mounting, which is important for continuous operation, and an MTBF of 50000 hours indicates a long expected life under normal conditions. With a 3-pin connector, the fan easily connects to motherboards, fan controllers, or other devices with a 12 V output, and the consumption of 5.28 W remains perfectly reasonable for most systems.

• Compact form factor 40 x 40 x 28 mm, suitable for tight spaces, small cases, and specialized equipment.
• Very high rotation speed of 12000 RPM, providing aggressive cooling in a limited size.
• Airflow up to 18.94 CFM / 32.18 m3/h, which helps effectively dissipate heat from radiators and hot zones.
• Bearing system 2 Ball Bearing, optimal for 24/7 operation and mounting in various positions.
• Declared noise level below 46 dBA, expected for such a high-speed 40 mm fan.
• Standard 3 Pin connector for easy connection to 12 V fan headers and controllers.
• Rated power 5.28 W / 12 V, compatible with most motherboards and devices, plus 50000 hours MTBF for durability.
• 6 months warranty from the manufacturer Evercool for peace of mind during intensive use.

Who it is suitable for

This Evercool 40 mm fan is a good choice if you need strong spot cooling in an SFF machine, server, networking device, 3D printer, NAS, or other compact chassis. It is also suitable for replacing OEM fans in power supplies or industrial equipment where the size of 40 mm and 12 V are mandatory. If you are looking for nearly silent operation for an office environment or HTPC on your desk, this model may seem noisy due to the high speeds.

The combination of small size, 12000 RPM, Ball Bearing bearings, and stable airflow makes EC4028HH12BA a very practical tool for solutions where cooling is more important than silence and space is limited.
