Ideal for illuminated builds

The JONSBO ZA-120B is a single 120mm case fan with a 28mm profile and addressable RGB lighting. Its four-sided infinity mirror design creates a layered visual effect suited for showcase chassis. Builders seeking a unified lighting ecosystem can connect the 3-pin ARGB header directly to a compatible motherboard.

Sustained airflow and acoustics

Speed varies between 700 and 2400rpm, delivering static pressure from .49 to 2.46 mmH2O across the range. Noise output scales from 21.3 to 37.3 dB(A), allowing quiet operation at low speed and stronger airflow when thermal load rises. PWM control adjusts the curve automatically without manual intervention.

Aluminium accent and simple wiring

An aluminium CD-pattern nameplate adds a rigid trim to the frame. The joint structure lets multiple fans clip together for aligned installation. One combined cable carries both 4-pin PWM and 3-pin ARGB signals, reducing internal clutter. Buyers needing thinner 25mm fans for tight clearances should look elsewhere.

At 2400 RPM the fan reaches 37.3 dB(A); at the minimum 700 RPM it drops to 21.3 dB(A).

What motherboard headers are required for the 4-pin PWM and 3-pin ARGB connectors on this fan?

A standard 4-pin PWM header for speed control and a 3-pin 5 V ARGB header for lighting sync.

Will the 28 mm thick ZA-120B fit alongside older 25 mm fans in the same case?

The 28 mm frame is 3 mm thicker than standard fans, so check your case clearance before mixing sizes.
