Evercool 40x40x7 1Ball (5500 RPM) EC4007M12CA

Evercool 40x40x7 1Ball (5500 RPM) EC4007M12CA is a compact 40 mm fan designed for situations where space is limited but cooling is critical – small cases, routers, mini-PCs, DVRs, 3D printers, and all sorts of small electronics. With a thickness of only 7 mm and a ball bearing, this fan is designed to operate reliably even at higher temperatures and in more confined spaces. At 5500 RPM, it provides a decent airflow for its size, while the noise remains below 25 dBA. It is powered by standard 12 V and connects easily with a 3-pin connector.

What you get

You get a small but effective fan with an airflow of up to 6.58 CFM (11.18 m3/h), which is more than enough for cooling chips, VRM zones, power modules, or enclosed mini systems. The bearing is a ball bearing, which usually means better durability and less risk of seizing during long operation compared to cheap sleeve options. With a power consumption of only 1.08 W, this fan hardly burdens the power supply, and the low noise level below 25 dBA makes it suitable for devices that operate constantly near you. An MTBF of 35000 hours gives a guideline for expected life under normal conditions – it's not industrial level, but it's fully adequate for home and office use.

• Compact form factor with a size of 40 x 40 x 7 mm, suitable for tight spaces in mini-PCs, routers, NVR/DVR, and other devices.
• Speeds up to 5500 RPM, providing quick air exchange and stable cooling for small but hot components.
• Airflow up to 6.58 CFM / 11.18 m3/h, sufficient for targeted cooling of chips, radiators, and local hot spots.
• Low noise level below 25 dBA, so the fan does not disturb in a quiet room or office environment.
• Ball Bearing bearing for better longevity and more reliable operation under continuous load and higher temperatures.
• Standard 12 V power supply and 3 Pin connector for easy connection to the motherboard, controller, or external power supply.
• Declared life of 35000 hours MTBF and 6 months warranty, sufficient for typical home and office configurations.

Who it is suitable for

This fan is suitable if you need a small, inexpensive, and effective cooling solution for a specific component or compact device where standard 80/120 mm fans simply won't fit. It is suitable for modding, replacing noisy or worn stock fans in networking/multimedia equipment, or for DIY projects with limited space. If you are looking for massive airflow for a large case or a powerful gaming build, this size will not be sufficient for you.

The most sensible aspect of this model is the combination of ultra-compact dimensions, ball bearing, and decent airflow at under 25 dBA noise, making it a practical choice for reliable cooling in small devices.
