Compact 40 mm Server Fan

This 40 mm by 28 mm axial fan is built for 1U server chassis where vertical space is measured in millimetres. It runs on 12 V and draws .78 A, delivering focused airflow directly over low-profile CPU heatsinks. The black frame and ball-bearing motor suit continuous operation in rack-mounted equipment. System integrators maintaining dense compute nodes will find the form factor matches legacy 1U layouts.

12 V .78 A Power Draw

The single decisive figure is the 12 V .78 A rating, which determines whether the fan can be powered from a standard motherboard header or requires a dedicated supply rail. At .78 A the current exceeds many 3-pin header limits, so verify the board's per-header budget before connecting. No PWM or tachometer wire is present, so speed control and monitoring are not available through the two-wire lead.

Two-Wire Ball-Bearing Install

Installation is a four-screw mount into the standard 40 mm hole pattern found on most 1U heatsinks. The ball bearing reduces start-up friction but transmits more vibration than sleeve types; use the supplied rubber grommets if resonance appears. The bare two-wire lead has no keyed connector, so polarity must be observed manually — reverse wiring will stall the motor. No LED or extra wiring simplifies cable routing in tight trays.

Spurningar um þessa vöru

What does the 12 V .78 A rating mean once the fan is installed in a 1U server?

At 12 V the fan draws 0.78 A, a modest current that fits easily within a 1U chassis power envelope.

How does the 2-wire power connector affect speed control in practice?

The 2-wire connector supplies constant 12 V power, so the fan runs at a fixed speed with no PWM or voltage regulation.

Will the 40 mm by 28 mm frame mount in a standard 1U server bracket?

The 40 mm square frame and 28 mm thickness match the typical 1U server fan mounting pattern.
