Compact 40 mm fan for tight builds

The OEM Industries EC4010LL12EA is a 40 mm square fan designed for small-form-factor systems, routers or network switches where space is at a premium. Its 10 mm thickness keeps the profile low enough for 1U chassis and cramped CPU cooler mounts. The three-pin connector provides simple voltage control on standard motherboard headers.

EL bearing keeps noise and draw low

An EL bearing reduces friction so the fan runs quietly at its rated 12 V and 0.04 A. The low current draw means minimal impact on a system’s power budget while still moving air through restrictive grilles. Black frame and blades blend into dark interiors without LED distraction.

Steady airflow under continuous duty

The bearing design maintains consistent speed during extended operation rather than slowing as temperature rises. Continuous 12 V supply keeps rotational velocity stable in always-on devices such as routers or embedded servers. No PWM signalling is present so speed scales directly with applied voltage.

Questions about this item

How do I connect the 3-pin plug to a 12 V header without reversing the wires?

Align the guide tab on the 3-pin connector with the slot on the motherboard or controller header; the keyed design prevents reverse insertion, then press firmly until seated.

When should I replace the EL bearing fan in the EC4010LL12EA?

Replace the fan when bearing noise increases, rotation becomes uneven, or airflow drops noticeably; the EL bearing is not user-serviceable and has no published relubrication interval.

What thermal limit appears first when this 40 mm fan runs continuously at 12 V and 0.04 A?

The small 40×10 mm frame moves limited air volume, so the heatsink temperature rises until the CPU throttles or the fan reaches its maximum speed ceiling.
