120 mm ARGB case fan

The MSI MPG EZ120 ARGB-1B is a single 120 mm case fan with a 28 mm frame and addressable RGB lighting. It targets builders who want simplified cabling and synchronised lighting effects in a standard 120 mm mounting pattern. The magnetic connector blocks join two fans together for power and signal without extra cables. It suits systems that can accommodate the thicker 28 mm profile.

PWM control limits

Speed is regulated through a 4-pin PWM connection with a range of 0 to 1900 RPM ±10%. At maximum speed the fan delivers 73.82 CFM airflow and 2.56 mmH2O static pressure while producing 28.82 dBA noise. The 7-pin JAF connector combines PWM and ARGB signals, so a compatible motherboard header or the supplied splitter cable is required for full control. Without PWM the fan runs at fixed voltage.

Magnetic build and mounting

The frame uses a fluid dynamic bearing for durability and embeds magnets that align with the supplied decorative blocks. Two fans snap together, sharing power and ARGB data through the patented connector blocks. The package includes M5 10 mm and #6-32 33 mm screws for different mounting standards. The 33 addressable LEDs are arranged for visibility from multiple angles. Builders needing thinner fans or traditional screw-only mounting should consider other models.

Questions about this item

Should I buy a single MPG EZ120 ARGB fan or add a second one for the magnetic connector blocks?

Each fan includes three decorative blocks and cables for standalone use. A second fan lets you snap the two together magnetically, sharing one 7-pin JAF power link and one 3-pin ARGB link to reduce cable count.

What does 1900 RPM actually deliver inside a case?

At full speed the 120 mm fan moves 73.82 CFM with 2.56 mmH₂O static pressure while producing 28.82 dBA, so it pushes enough air for radiators or dense meshes without becoming loud.

How do the 7-pin JAF and 3-pin ARGB connectors work with my motherboard?

The 7-pin JAF header carries 4-pin PWM power and speed control plus the ARGB signal in one plug; a split cable is also supplied for boards with separate 4-pin PWM and 3-pin 5 V ARGB headers.
