Pros & Cons
Pros
- ✓ Daisy-chain design runs a full fan bank off one 4-pin PWM and one +5V ARGB header
- ✓ 3.46mm-H2O static pressure makes them viable radiator fans, not just case intakes
- ✓ 95.5 CFM and 1,700 RPM ceiling from a 140mm frame
- ✓ AirGuide anti-vortex vanes aim airflow at hot components instead of scattering it
Cons
- ✗ ARGB needs a compatible motherboard +5V header; no controller in the box
- ✗ Eight LEDs per fan is modest next to denser 20+ LED ARGB rings
- ✗ 1,700 RPM top speed will be audible at full tilt despite the Magnetic Dome bearing
- ✗ 140mm only, so it will not fit 120mm radiator or case mounts
Manufacturer description
The CORSAIR RS140 ARGB dual pack gives you two 140mm PWM fans built around daisy-chain wiring, so a bank of fans runs off a single 4-pin PWM header and a single +5V ARGB header instead of a nest of splitters behind the motherboard tray. Each fan spins up to 1,700 RPM and moves up to 95.5 CFM, with 3.46mm-H2O of static pressure that lets the RS140 work as a radiator or heatsink fan rather than just a case intake. CORSAIR's AirGuide anti-vortex vanes concentrate the airflow column at your hottest components instead of letting it scatter across the chassis. Lighting comes from eight LEDs per…
SpecPicks Verdict
SpecPicks scored CORSAIR RS140 ARGB 140mm PWM Fans using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Corsair's PC & gaming hardware 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 PC & gaming hardware 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 hub to use the RGB?
No. The eight LEDs per fan are driven through your motherboard's built-in +5V ARGB control, so a compatible ARGB header is required but no separate Corsair controller is listed as needed.
Can I use the RS140 ARGB on a radiator?
Yes. Corsair rates these RS fans at 3.46mm-H2O static pressure specifically so they can push air through radiator and heatsink fin stacks, not just open case vents.
How many fans can I daisy-chain together?
Corsair does not publish a chain limit in this listing. The design links multiple fans to one 4-pin PWM connector and one +5V ARGB connector; check the product listing for the maximum supported chain length.
How fast and how loud do these fans run?
PWM speed tops out at 1,700 RPM with up to 95.5 CFM of airflow. Corsair uses a Magnetic Dome bearing for quieter operation, but no dBA figure is given in this listing.
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 1,700 RPM while providing up to 95.5 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 3.46mm-H2O to push through obstructions.
