Compact 40 mm case fan

The Zyvpee DB04028B12S P141 is a 40 mm by 28 mm DC fan built for tight chassis where larger units cannot fit. It suits builders who need targeted airflow for small-form-factor boards, embedded appliances or GPU heatsink replacement. The three-pin connector provides simple voltage control without PWM circuitry. Buyers who want more airflow or quieter operation at low speed should look elsewhere.

12 V .96 A ball-bearing motor

Rated at 12 volts and 0.96 amps the motor spins up to 1600 RPM delivering focused cooling for hot-spots such as VRM zones or M.2 slots. The ball bearing tolerates continuous operation and horizontal mounting better than sleeve alternatives. Headroom disappears quickly when static pressure rises, so dense radiator fins or restrictive grilles will stall the impeller. It is not suited for high-impedance radiator stacks.

Three-pin voltage control only

The 3-pin header accepts standard motherboard fan headers but lacks a fourth PWM wire, so speed varies with voltage rather than duty-cycle. Some boards cannot reduce voltage low enough for silent idle, leaving the fan at a fixed minimum RPM. Verify that your header supports DC mode before purchase. Builders needing automatic PWM curves or software-addressable lighting will find this connector insufficient.

Questions about this item

Will the 3-pin connector on this 40 mm fan work with a motherboard header that only has 4-pin sockets?

The 3-pin plug fits a 4-pin header; the fourth pin is left unused and the fan will run at full 12 V speed.

How can I confirm the fan is spinning at the rated speed once installed?

Check the RPM reading in BIOS or monitoring software; it should report below 1600 RPM under normal load.

Does the package include mounting screws or a 3-pin to 4-pin adapter?

The box contains only the 40x28 mm ball-bearing fan with 3-pin lead; screws and adapters are sold separately.
