CORSAIR RS120 ARGB 120mm PWM Fans
Bottom line: The CORSAIR RS120 ARGB 120mm PWM Fans ($34.99 on Amazon as of 2026-10-06): Daisy-chain wiring runs all 3 fans off one PWM header and one ARGB header; main trade-off: ARGB needs a compatible motherboard header; no controller in the box.

Pros & Cons
Pros
- ✓ Daisy-chain wiring runs all 3 fans off one PWM header and one ARGB header
- ✓ 2.8mm-H2O static pressure suits radiators and restrictive dust filters
- ✓ 72.8 CFM airflow and 2,100 RPM ceiling from a 120mm frame
- ✓ AirGuide anti-vortex vanes aim airflow at hot components, not the whole case
Cons
- ✗ ARGB needs a compatible motherboard header; no controller in the box
- ✗ Eight LEDs per fan is modest next to dual-loop ARGB rings
- ✗ 2,100 RPM ceiling means audible noise at full PWM duty
- ✗ 120mm only, so no 140mm option for larger case mounts
Manufacturer description
The CORSAIR RS120 ARGB is a triple pack of 120mm PWM case fans built for builders who want daisy-chained cable runs instead of a nest of splitters. Each fan links to the next, so all three run from a single 4-pin PWM header and a single +5V ARGB header on your motherboard. That matters in compact builds where header count runs out before fan mounts do. Performance is squarely in radiator territory: speeds scale up to 2,100 RPM, airflow reaches 72.8 CFM, and static pressure hits 2.8mm-H2O, enough to push through dense fin stacks and dust filters rather than stalling against them. Corsair's…
SpecPicks Verdict
SpecPicks scored CORSAIR RS120 ARGB 120mm PWM Fans 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.

Frequently Asked Questions
Do these fans need a Corsair controller or hub?
No. The RS120 ARGB daisy-chains into one 4-pin PWM connector and one +5V ARGB connector that plug straight into your motherboard. ARGB lighting requires a motherboard with a compatible +5V ARGB header.
Are the RS120 ARGB fans good for an AIO radiator?
Yes. They are rated at 2.8mm-H2O static pressure, which Corsair positions specifically for pushing air through radiator fins, and AirGuide vanes concentrate airflow when mounted to a radiator or heatsink.
How fast and how much air do they move?
PWM speed tops out at 2,100 RPM with up to 72.8 CFM of airflow per fan. Because they are PWM, your motherboard can throttle them down for quieter idle operation.
How many fans come in this pack?
This is a triple pack, so you get three 120mm fans plus the daisy-chain cabling needed to link them to a single PWM and single ARGB header.
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.
