Evercool 40x40x7 1Ball (5V,5500 RPM) - EC4007H05CA

Evercool EC4007H05CA is a compact 40 mm fan aimed at small systems where space is critical – mini PCs, routers, NAS cases, 3D printers, or as a replacement for factory coolers in tight spaces. The thickness of only 7 mm makes it convenient for situations where a standard 40x40x10 fan does not fit. It operates at 5 V, which is suitable for devices and controllers that do not provide the standard 12 V for PC fans. With up to 5000 RPM and an airflow of 5.64 CFM, it maintains a good balance between cooling and noise.

What you get

This fan features a Ball Bearing bearing, which means better durability during long operation and a lower chance of wobbling and buzzing at higher speeds compared to cheap sleeve solutions. With a noise level of <22 dBA, you can use it in devices that sit next to you on the desk without being constantly annoyed. The consumption is only 1.3 W at 0.26 A on 5 V, which is well within the capabilities of USB-like power supplies, controllers, or embedded boards. With a 3 PIN connector, you can connect it to many standard controllers and boards that provide 5 V, while keeping track of the RPM if the device supports it. An MTBF of 35000 hours is sufficient for long continuous operation in small systems or as a replacement fan in sensitive electronics.

• Compact form factor 40 x 40 x 7 mm, convenient for tight cases, modules, and devices with limited space.
• Operating voltage 5 V, suitable for embedded systems, controllers, and devices that do not use standard 12 V fans.
• Speed up to 5000 RPM, providing stable airflow for cooling chips, VRM, driver boards, or small radiators.
• Airflow 5.64 CFM / 9.58 m3/h, sufficient for local spot cooling in compact spaces.
• Low noise level <22 dBA, suitable for desktop devices and offices where constant noise is a problem.
• Bearing Ball Bearing, providing higher durability and better performance during long operation and higher temperatures.
• 3 PIN connector for easy integration into systems that support RPM monitoring, plus MTBF 35000 hours for reliable operation.

Who it is suitable for

It is suitable if you are looking for a thin 5V fan for a small case, embedded electronics, a router, a mini server, or as a replacement for an old noisy 40 mm fan. It is also suitable for DIY projects where you need to cool a specific component without changing the entire design. It is not suitable if you want powerful airflow for large PC cases or standard 12 V systems without modifications.

The most sensible aspect here is the combination of thin 40 mm form factor, 5 V power supply, and Ball Bearing bearing – exactly the type of fan that solves difficult cooling situations in small spaces without generating excessive noise.
