40×28 mm 12 V 4-pin server fan

The Zyvpee 04028DA-12R-AUF is a 40 mm by 28 mm DC axial fan built for server CPU cooling. It runs on 12 V and draws 0.52 A through a standard four-pin power connector. The black frame uses a ball bearing and has no LED lighting.

Suits tight 40 mm bays needing PWM control

Installers who need a 40×28 mm footprint with four-wire speed control will find this fan fits directly. Builders who require a larger frame, RGB illumination or a different bearing type should look elsewhere.

40×28 mm physical footprint

The 40 mm by 28 mm outline is the single dimension that decides whether this fan matches the mounting holes and clearance of the target chassis. Verify the exact cut-out before ordering.

Questions about this item

Does the Zyvpee 04028DA-12R-AUF include mounting screws or do I need to buy them separately?

The fan ships alone; standard 40 mm mounting screws are not included and must be sourced separately.

How do I choose between the 12 V 0.52 A version and other capacities for this 40×28 mm frame?

This model is only offered as a 12 V 0.52 A ball-bearing unit; no alternative voltage or current ratings exist for the 40×28 mm size.

What does the 0.52 A current draw mean for PWM control on a typical motherboard header?

At 0.52 A the fan stays well within a standard 1 A PWM header limit, allowing full speed control without risk of overload.
