Compact 40 mm case fan for tight builds

The Zyvpee 1604KL-04W-B49 M51 is a 40 mm square frame fan designed for small-form-factor cases and network equipment. It runs on 12 V DC at 0.1 A through a standard three-pin power connector. Ball-bearing construction supports continuous operation in confined spaces. The black, non-LED finish keeps the unit visually neutral inside any chassis.

Fits 40*10 mm mounts and three-pin headers

This fan occupies a 40 mm by 10 mm footprint, matching common router and mini-ITX mounting holes. The three-wire lead plugs directly into a motherboard or controller three-pin header for voltage-based speed control. No separate power adapter or PWM circuitry is required. Its low current draw leaves ample headroom on a 12 V rail for other components.

Replaces noisy sleeve-bearing 40 mm fans

Builders swapping out a worn 4010 sleeve-bearing unit gain quieter start-up and longer service life from the ball-bearing design. The upgrade is worthwhile when the original fan develops rattle or fails to spin at low voltage. It is not suited for high-static-pressure radiator mounts or builds demanding PWM precision.

Questions about this item

How long does the ball bearing last under continuous 12 V operation?

The ball bearing is rated for extended continuous running at 12 V and 0.1 A without lubrication failure.

What noise and heat levels occur when the fan runs all day at 12 V?

At 12 V and 0.1 A the 40 mm ball-bearing fan produces low acoustic output and minimal heat rise during all-day use.

Which motherboard header is required for the 3-pin connector?

A standard 3-pin 12 V DC fan header on the motherboard or fan controller is needed to power the fan.
