Corsair RS120 ARGB 120mm ARGB Fan Single Pack - CO-9050180-WW

This Corsair RS120 ARGB 120mm is a versatile case and radiator fan, aimed at mid-range and more serious gaming/enthusiast builds. It combines the 120 mm format with a magnetic bearing for a longer lifespan and lower noise. The 420–2100 rpm range provides wide control – from nearly silent operation to aggressive cooling when needed. Add Addressable RGB lighting and you get a good balance between looks and functionality.

What you get is a fan that can operate truly quietly at low speeds – from 10 dB(A), and push airflow up to 123.7 m³/​h (72.8 CFM) when you stress the system. Thanks to a maximum pressure of 4.15 mmH₂O, it is suitable for radiators where air must pass through dense fins, not just through the mesh filters of the case. The magnetic bearing reduces friction, which helps simultaneously with lower noise and better durability during long gaming sessions at high speeds. With a 4-pin connector, you have PWM control via the motherboard, while the separate 3-pin 5V ARGB gives you lighting synchronization with the other components.

• Size 120 x 120 x 25 mm – standard 120mm format that fits most cases and 120/240/360mm radiators.
• Speed 420–2100 rpm – wide range for fine-tuning between absolutely silent idle and strong cooling under load.
• Airflow 22.6–123.7 m³/​h (13.3–72.8 CFM) – sufficient for effective airflow in the case or passing through a dense radiator.
• Max. pressure 0.2–4.15 mmH₂O – makes the fan suitable for both intake/exhaust and mounting on water radiators.
• Noise level 10–36 dB(A) – option for nearly silent operation at low speeds and controllable noise at maximum cooling.
• Magnetic Bearing – lower friction and better long-term durability compared to basic sleeve/bearing solutions.
• Addressable RGB with 3-pin 5V connector – separate ARGB control and synchronization of effects with the motherboard or controller.
• Color: black – neutral appearance that looks good in almost any build.
• Warranty 60 months – long-term coverage from the manufacturer for more peace of mind.

This fan is suitable if you are assembling a gaming or enthusiast system with an emphasis on good airflow, noise control, and synchronized RGB. It looks good both as a front intake/exhaust in a black case and on an AIO radiator. If you are looking for an absolutely minimal budget regardless of looks and bearings, this will probably be more premium than you need.

The combination of a wide rpm range, magnetic bearing, and strong static pressure, plus flexible ARGB control, makes the Corsair RS120 ARGB a very reasonable choice for a modern, well-cooled, and visually finished build.
