Triple-pack ARGB PWM fans for case cooling

This Corsair RS120 triple pack provides three 120mm case fans with addressable RGB lighting and PWM speed control. Each fan uses a magnetic dome bearing and runs from 420 to 2100 RPM with a zero-RPM mode for silent idle. The pack suits builders who want coordinated airflow and lighting across multiple mount points in a standard ATX or mid-tower chassis.

Daisy-chain wiring replaces individual headers

Instead of occupying three separate fan and ARGB headers, the fans connect in series through one 4-pin PWM connector and one +5V ARGB connector. This simplifies cable routing and frees motherboard headers for other devices. The jump is worthwhile when your board has limited headers or when you prefer a single control curve for all three fans rather than managing them independently.

Check for +5V ARGB header and mounting clearance

Your motherboard must supply a standard +5V ARGB header to drive the lighting; a 12V RGB header will not work. Verify that your case or radiator has 120mm mounting holes with 25mm depth clearance for each fan. The package includes 12 mounting screws, so no additional hardware is required if the mounting pattern matches.

Questions about this item

What clearance does the 120mm by 25mm frame need in my case?

Each fan measures 120mm square and 25mm thick, so the case or radiator must provide at least 25mm depth per fan plus room for the daisy-chain cables.

How do I connect the three fans using the daisy-chain PWM and 5V ARGB headers?

Link the 4-pin PWM and +5V ARGB leads from fan to fan, then plug the first fan into a single motherboard PWM header and a single 5V ARGB header; do not mix 12V RGB headers.

When should I expect the Magnetic Dome bearing to need attention?

The Magnetic Dome bearing is designed for low friction and long life; no routine lubrication is required, and the fan supports Zero RPM mode to reduce wear at idle.
