Evercool 40x40x10 EL Bearing (4000 RPM) EC4010LL12EA

Evercool EC4010LL12EA is a compact 40 mm fan, ideal for small cooling tasks – small cases, networking equipment, mini-PCs, or replacing an OEM fan in a power supply/device. It operates at up to 4000 RPM, but maintains noise below 17 dBA, which is important when the fan is close to you on the desk. The EL Bearing and MTBF of 40000 hours suggest decent reliability for continuous operation. Its consumption is minimal – only 0.48 W at 12 V, so the load on the power supply is practically zero.

What you get

With a size of 40 x 40 x 10 mm, this fan is thin and convenient for tight spaces where standard thicker models won't fit. The airflow is 2.5 CFM (4.25 m3/h) – more than enough for spot cooling of a chip, VRM, networking device, or small radiator. The noise level below 17 dBA makes it suitable for devices that operate constantly near you – like a home router, NAS case, or small HTPC. The 3 PIN connector allows easy integration into a motherboard or controller, without the need for adapters, as long as you have a free 3-pin header. With a low amperage of 0.04 A, you can safely connect it to a splitter with other small fans without worrying about the load.

• Compact size with standard 40 mm and actual dimensions 40 x 40 x 10 mm, suitable for tight cases and embedded devices.
• Speeds up to 4000 RPM, providing stable airflow for small radiators and chips.
• Airflow 2.5 CFM / 4.25 m3/h, optimized for spot cooling in compact configurations.
• Low noise level below 17 dBA, suitable for 24/7 operation in an office or home environment without annoying whirring.
• EL Bearing with MTBF of 40000 hours, providing long life under continuous load.
• Low consumption – only 0.04 A and 0.48 W at 12 V, gentle on the power supply and electronics.
• Standard 3 PIN connector for direct connection to motherboards or fan controllers without additional adapters.

Who it is suitable for

This fan is convenient if you need quiet and compact cooling for a mini-PC, networking equipment, small server, NAS, or to replace a factory 40 mm fan in a device. It is not a solution for high airflow in large cases or powerful gaming systems – its role here is more of a spot and auxiliary cooling, rather than primary cooling.

The strongest point of this model is the combination of a very compact form factor, low noise, and modest consumption, making it a practical choice for small but important cooling tasks.
