40x28mm 12V 4-Pin case fan
The Zyvpee SG40281B1-0000-S99 is a compact case fan measuring 40 by 28 millimetres. It operates on 12 volts and draws 6.24 watts through a standard 4-pin power connector. Ball bearings support the rotor for reliable operation in server and workstation chassis. The black frame carries no LED lighting.
Suits tight server bays; not for large chassis
This fan fits 40mm mounting holes where space is at a premium, such as 1U rack blades or small-form-factor enclosures. Builders needing higher airflow for full-size ATX cases or quiet desktop cooling should look at larger diameter units instead. The 4-pin PWM header allows speed control when the motherboard supports it.
40x28mm footprint decides fit
The 40 by 28 millimetre frame is the single dimension that determines whether this fan will mount in your chassis. Verify the exact cut-out and screw spacing before purchase. If the bay requires a different thickness or hole pattern, this model will not install.

Questions about this item
Does the 40×28 mm frame match standard 4028 mounting holes?
The fan measures 40 by 28 mm, so it fits the 4028 screw pattern used on many server and small-form-factor chassis.
Which wire on the 4-pin connector carries the PWM signal?
The fourth pin on the 4-wire connector provides the PWM control signal; the other three carry 12 V power, ground and tachometer output.
How often should the ball bearing be relubricated in continuous server use?
Ball bearings are sealed for life and do not require relubrication; replace the fan if noise or vibration increases.
