CORSAIR RS140 ARGB 140mm PWM Fans Dual Pack - Quiet, High-Pressure

In this review the CORSAIR RS140 ARGB 140mm PWM dual pack is evaluated as a balanced choice for PC builders who need strong airflow, radiator compatibility, and simple RGB control. The biggest reason to consider this pair is the combination of daisy-chain connectors and CORSAIR AirGuide technology, which together deliver concentrated cooling and straightforward setup through a single 4-pin PWM and a single +5V ARGB header on compatible motherboards. The fans aim to be quiet under load while offering enough static pressure to work on radiators as well as in case intakes or exhausts.

Key Features

• Daisy-chain connections: Link multiple fans together and control fan speed and lighting with just one 4-pin PWM and one +5V ARGB connector, simplifying cable management and motherboard header use.
• Eight LEDs per fan: Bright per-fan ARGB lighting provides customizable effects when used with a compatible motherboard, making illumination easy without extra controllers.
• Precise PWM speeds: Fans reach up to 1,700 RPM and can be finely controlled by the motherboard to balance airflow and noise for varied workloads.
• CORSAIR AirGuide technology: Anti-vortex vanes focus airflow toward hot components, which improves cooling efficiency when mounted on radiators or heatsinks.
• High static pressure: With a static pressure suited to push air through obstructions, the RS140 performs well as a radiator fan as well as a case fan.
• Magnetic dome bearing: The bearing design promotes quieter operation and longer life, and Zero RPM mode reduces noise at low system loads.

Who It's For

The CORSAIR RS140 ARGB dual pack is best for PC builders who want a tidy wiring setup and dependable cooling performance for mid-range to high-performance systems, especially those using a single motherboard ARGB header. It suits users adding radiator fans or upgrading case airflow where focused, high static pressure is valuable.

It is less appropriate for users without a compatible +5V ARGB header who expect plug-and-play RGB from a controller included in the box, or for those prioritizing absolute silence above all else, since opinions on noise are mixed depending on individual builds and fan placement.

Pros & Cons

Pros

• Strong, concentrated airflow from AirGuide vanes that improves cooling on radiators and hot components.
• Simplified cabling and control via daisy-chain connectors that reduce the number of motherboard headers used.
• Bright, customizable ARGB lighting with eight LEDs per fan for vibrant color and effects.
• Reliable magnetic dome bearing and Zero RPM mode help reduce noise and extend fan life.

Cons

• Requires a compatible +5V ARGB motherboard header for lighting control; no standalone controller is included.
• Noise level impressions vary by user and setup, so some may find them less quiet in high-RPM scenarios.

Frequently Asked Questions

Do these fans need an ARGB controller?
They do not include a controller; lighting requires a compatible +5V ARGB motherboard header to customize colors and effects.

Can these be used on radiators?
Yes, the fans have higher static pressure (3.46 mm-H2O) and are suitable for radiator mounting as well as case airflow.

Are they quiet in normal use?
Many users report quiet operation thanks to the magnetic dome bearing and Zero RPM mode, but noise impressions vary with RPM and case acoustics.
