Starter kit with three 120mm fans

This Corsair QX120 RGB starter kit provides three 120mm case fans and an iCUE LINK controller in a single package. The fans use a magnetic dome bearing and spin from 0 to 2400 RPM with a ±10% tolerance. Each unit delivers between 16.4 and 63.1 CFM while producing 10 to 37 dBA. The kit is designed for builders who want unified RGB lighting and fan control through iCUE software.

Suits iCUE ecosystems, not other controllers

The kit suits PC builders who already use Corsair iCUE LINK components or want a single ecosystem for lighting and fan curves. It is not for builders who rely on standard 4-pin PWM or 5V ARGB headers without an iCUE LINK controller. Buyers needing thicker fans or different frame dimensions should look at other specifications.

Magnetic dome bearing with zero RPM mode

The magnetic dome bearing enables a zero RPM mode where fans stop completely at low temperatures. This bearing type reduces friction and noise at the 10 dBA floor while supporting speeds up to 2400 RPM. The 25mm thickness fits standard 120mm mounting points. This bearing characteristic is the key factor when choosing these fans for quiet operation.

Questions about this item

How do I connect the three QX120 RGB fans using the iCUE LINK bridge connectors?

Daisy-chain each fan with the included bridge connectors into a single iCUE LINK port on the controller, then plug the controller into a motherboard USB header for software control.

When will the magnetic dome bearings need replacement?

The magnetic dome bearing has no physical contact surfaces, so it does not wear out like sleeve or ball bearings and requires no scheduled replacement.

At what noise level does the kit hit its thermal ceiling under sustained load?

At the maximum 2400 RPM the fans produce 37 dBA while moving 63.1 CFM; beyond that point neither speed nor airflow increases.
