Compact 40 mm server fan
The Zyvpee W40S12BS4A5-57 is a 40 mm square case fan designed for tight server and workstation chassis. Its two-ball bearing and 4-pin PWM connector suit builds that need reliable airflow in a 40 x 40 x 20 mm footprint.
Sustained 12 V operation
Running continuously at 12 V and 0.73 A, the dual-ball bearing maintains consistent speed without the wear seen in sleeve designs. The 4-pin interface allows the motherboard to adjust duty cycle under prolonged thermal load.
Verify 40 mm mount and 4-pin header
Confirm your chassis has 40 mm mounting holes and that the board provides a 4-pin fan header for PWM control. Builds limited to 3-pin headers or larger fan frames cannot use this unit.

Kysymyksiä tästä tuotteesta
How loud is the 40×40×20 mm 12 V 0.73 A 2-ball fan when it runs continuously in a server chassis?
The fan uses a dual ball bearing and a 4-pin PWM connector, so speed can be lowered via the motherboard to reduce noise during extended operation.
What must my motherboard or controller provide to run this 4-pin 12 V 0.73 A case fan?
A standard 4-pin PWM header supplying 12 V and at least 0.73 A per fan is required; the connector carries power, ground, tachometer and PWM control signals.
Will this 40 mm 12 V 0.73 A 2-ball fan fit alongside older 4028-size coolers that use 3-pin headers?
The physical 40×40×20 mm footprint matches the 4028 form factor, and the 4-pin plug works in a 3-pin header at fixed 12 V, though PWM speed control will be unavailable.
