Compact 40mm CPU cooler fan

The Zyvpee DB04028B12U is a 40 by 28 millimetre axial fan built for CPU cooler mounting. It runs on 12 volts and draws 0.66 amps through a three-wire connector. The black frame houses a two-ball bearing for continuous operation.

Three-wire 12V power connector

The three-wire lead is the only electrical interface; it supplies power and a tachometer signal to the motherboard header. A four-pin PWM header will not provide speed control with this fan. Buyers needing variable speed via PWM should choose a four-wire model instead.

Simple screw mounting with clearance check

Four corner holes accept standard M3 screws for direct attachment to a compatible heatsink. Verify that the 40 by 28 millimetre footprint and 28 millimetre thickness fit the cooler shroud before ordering. The three-wire plug must reach the CPU fan header without strain.

Questions about this item

How much current will the 12V 0.66A rating draw in a live system?

The fan draws up to 0.66A from a 12V rail, so budget roughly 8W for thermal headroom when planning your power budget.

What does the 3-wire connector actually control on this unit?

The three wires carry power, ground and a tachometer signal, giving the motherboard RPM feedback without PWM speed control.

Will the 40 * 28mm frame clear standard 40mm mounting holes?

Yes — the 40mm square frame matches common 40mm hole spacing, while the 28mm thickness fits most slim CPU-cooler brackets.
