Compact 40 mm server fan

The LORDWORLD 1611RL-04W-B59 is a 40 mm square frame fan measuring 40 x 40 x 28 mm. It runs on 12 V DC drawing 0.22 A and connects via a standard three-pin header. This form factor fits tight server and network chassis where airflow must be directed through narrow channels.

Replaces worn 4028 units

Swap this in when an existing 40 mm three-pin fan becomes noisy or fails to spin at rated speed. The upgrade is worthwhile when the original bearing has degraded or when a maintenance schedule calls for fresh airflow assurance in dense rack equipment. Builders needing larger frames or different voltage rails should look elsewhere.

Questions about this item

What are the mounting hole dimensions for the 40x40x28mm frame?

The fan uses a standard 40mm square frame with mounting holes spaced for 40mm centres; use four M3 screws through the corner holes to secure it in a 4028-compatible chassis cut-out.

How do I connect the three-pin lead correctly, and what is the common mistake?

Align the keyed 3-pin connector with the motherboard or controller header — yellow for 12V, black for ground, and the third wire for tachometer signal; the frequent error is forcing it on offset by one pin, which reverses power and ground.
