Evercool 40x40x20 24V 2Ball (5500 RPM) Fan - EC4020H24BA

The Evercool EC4020H24BA is a small 40 mm fan oriented towards reliable 24V operation in compact systems – routers, 3D printers, industrial devices, small cases, and PSU modules. With a size of 40 x 40 x 20 mm and a 2 Ball Bearing, it is designed to last long at higher temperatures and vertical mounting. Speeds of up to 5500 RPM provide stable airflow for cooling in confined spaces without generating excessive noise. Add the standard 3 PIN connector and you get easy integration into many systems with 24V power supply.

What you get

With an airflow of 4.65 CFM (7.9 m3/h), this fan is more than sufficient for small radiators, driver coolers, MOSFETs, or control boards, where constant ventilation is important rather than massive airflow. The noise level of only 22 dBA is a plus if the fan will operate close to you – for example, in a 3D printer in the room or in a small control cabinet. Thanks to a consumption of 0.05 A and a total power of 1.2 W, the load on the 24V line is minimal, which is important in more limited PSUs or when you have several fans on one channel. The 2 Ball Bearing and MTBF of 50000 hours mean a long life at 24/7 operation, far better than cheap sleeve options. And with the 3 PIN connector, wiring is easy – directly to the board, fan hub, or adapter, without the need for exotic adapters.

• Compact size 40 x 40 x 20 mm, suitable for tight spaces, small cases, and embedded systems.
• High speeds of 5500 RPM, providing stable airflow for cooling hot components in a limited volume.
• Airflow 4.65 CFM (7.9 m3/h), sufficient for small radiators, drivers, and electronic modules.
• Low noise level of only 22 dBA, keeping your system quiet even during prolonged operation.
• Bearing 2 Ball Bearing with MTBF 50000 hours, providing reliability and longer life under 24/7 load.
• Operates at 24 V DC with a consumption of 0.05 A and power of 1.2 W, gentle on the power supply and allowing the use of multiple fans.
• Standard 3 PIN connector for easy connection to controllers, boards, and other devices.

Who it is suitable for

This fan is suitable if you need reliable 24V cooling for a 3D printer, CNC, power module, router, network device, or industrial electronics. It is also suitable for your own DIY projects where space is limited, but you do not want to sacrifice long-term reliability. It is not a suitable choice for primary cooling in large PC cases – there you need a larger diameter and more serious airflow.

The combination of 24V power supply, 2 Ball Bearing bearing, 5500 RPM, and MTBF 50000 hours makes the Evercool EC4020H24BA a stable little workhorse for systems that just need to run without drama.
