Model RS140 Dual Pack

  • Daisy-chain multiple fans via single 4-pin PWM connector for simplified control
  • AirGuide anti-vortex vanes concentrate airflow on hot components for targeted cooling
  • Magnetic Dome bearing reduces friction and noise for longer lifespan
  • Zero RPM mode stops fans completely at low loads eliminating noise
  • High 3.46 mm-H2O static pressure pushes air through radiators and heatsinks

Two-fan 140mm PWM pack

The Corsair RS140 dual pack delivers two 140mm case fans with 4-pin PWM control. Magnetic dome bearings enable a 0 to 1700 RPM range and a 10 to 36 dBA noise floor. AirGuide vanes focus airflow for concentrated cooling on radiators or heatsinks. Eight mounting screws are included for standard 140mm fan slots.

Suits radiator and high-static-pressure builds

Builders who want daisy-chained PWM control and up to 95.5 CFM with 3.46 mm-H2O static pressure will benefit. Systems that require addressable RGB lighting or larger frame sizes should look at other options. The non-LED black design keeps the interior dark for minimalist aesthetics.

Daisy-chain 4-pin PWM connector

A single 4-pin PWM header powers and controls both fans in series, reducing cable clutter and header usage. This connection method is the deciding factor for motherboards with limited fan headers or for clean routing in compact cases.

Perguntas sobre este artigo

Does the dual pack include everything needed to mount both 140mm fans?

Yes, the box contains two RS140 fans and eight mounting screws, which is the full set for installing both units.

Why choose the 140mm RS140 PWM dual pack over a single 120mm fan?

Each 140mm fan moves up to 95.5 CFM at 3.46 mm-H2O static pressure, giving more airflow and radiator performance per slot than smaller sizes.

What does the 0 to 1700 RPM range mean for daily use?

The fans can stop completely at 0 RPM for silent idle, then spin from 330 RPM up to 1700 RPM under load, staying between 10 and 36 dBA.
