CORSAIR RS120 ARGB 120mm PWM Fan
Bottom line: The CORSAIR RS120 ARGB 120mm PWM Fan ($15.99 on Amazon as of 2026-10-21 04:20 UTC): Daisy-chain wiring: one 4-pin PWM plus one +5V ARGB header runs the whole fan array; main trade-off: eight LEDs per fan is modest next to 16-20 LED rings on premium ARGB fans.

Pros & Cons
Pros
- ✓ Daisy-chain wiring: one 4-pin PWM plus one +5V ARGB header runs the whole fan array
- ✓ 72.8 CFM at 2,100 RPM covers intake, exhaust, and radiator duty from one SKU
- ✓ 2.8mm-H2O static pressure pushes through radiator fins and dense heatsink stacks
- ✓ AirGuide anti-vortex vanes focus the airstream at specific hot components
- ✓ Magnetic dome bearing plus Zero RPM mode for silence at low load
Cons
- ✗ Eight LEDs per fan is modest next to 16-20 LED rings on premium ARGB fans
- ✗ ARGB control requires a compatible motherboard header - no controller included
- ✗ Single pack, so a 3-fan front intake means buying three separate units
- ✗ 2,100 RPM ceiling trails high-RPM radiator fans built for thick rads
Manufacturer description
The CORSAIR RS120 ARGB is a 120mm PWM case fan built around one idea: fewer cables. Daisy-chain multiple RS120 fans and drive the whole array from a single 4-pin PWM header and a single +5V ARGB header on your motherboard, instead of running a separate pair of leads per fan. Airflow tops out at 72.8 CFM at 2,100 RPM, and static pressure of 2.8mm-H2O is enough to push through radiator fins and dense heatsink stacks, so the same fan works as an intake, an exhaust, or an AIO fan. Corsair's AirGuide anti-vortex vanes concentrate the airstream instead of letting it spread, which matters most when…
SpecPicks Verdict
SpecPicks scored CORSAIR RS120 ARGB 120mm PWM Fan using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Corsair's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Do I need a Corsair controller or iCUE to use the RGB?
No. The eight LEDs per fan run off your motherboard's built-in +5V ARGB header and its lighting software, so a compatible motherboard is the only requirement.
How many RS120 ARGB fans can I daisy-chain together?
Corsair does not publish a chain limit in this listing. The design links fans through one 4-pin PWM and one +5V ARGB connector; check the product listing and your motherboard header's current rating before building a long chain.
Is the RS120 ARGB good enough for an AIO radiator?
Yes. It is rated at 2.8mm-H2O static pressure, which Corsair specifies as sufficient to push air through radiator fins, and AirGuide vanes concentrate the airstream against the obstruction.
How much airflow and how fast does it spin?
Up to 72.8 CFM at a maximum PWM-controlled 2,100 RPM. PWM lets you dial speeds down for quieter operation, and Zero RPM mode stops the fan entirely at low load.
Does one purchase include more than one fan?
No. This is the Single Pack, one 120mm fan in black. Building a full intake or radiator set means ordering multiple units.
Key Features
- Streamlined Fan Connections: Daisy-chain multiple fans together and control them all through just one 4-pin PWM connector and one +5V ARGB connector.
- Lighting Made Easy: Eight LEDs per fan shine bright with customisable lighting through your motherboard’s built-in ARGB control (requires compatible motherboard).
- Precise PWM Speeds: Set your fan speeds up to 2,100 RPM while providing up to 72.8 CFM airflow to your system.
- CORSAIR AirGuide Technology: Anti-vortex vanes direct airflow at your hottest components for concentrated cooling, pushing air in the direction you need when mounted to a radiator or heatsink.
- High Static Pressure: RS fans work well as radiator fans with a static pressure of 2.8mm-H2O to push through obstructions.
