Fan Corsair iCUE LINK RX140 RGB 140mm PWM Single Fan Expansion - CO-9051019-WW

This is a 140 mm PWM Corsair fan from the iCUE LINK RX140 RGB series – an expansion (Single Fan Expansion) variant for cases and radiators. It is aimed at mid-range and high-end configurations where you want a good balance between air flow, pressure, and visuals. The combination of magnetic bearing and wide range 17.9 - 94.7 CFM makes it suitable for both strong intake/exhaust and radiator configurations. Add addressable RGB lighting and you get a fan that cools seriously and looks good in a black system.

What you get
With size 140 x 140 x 25 mm this fan covers standard slots for 140 mm slots in cases and 140 mm radiators. The wide range from 1700 RPM and pressure 0.15 - 3.75 mm-H2O means you can run it super quiet at low load or crank it up for aggressive cooling under full load. With air flow up to 94.7 CFM you can safely use it as a primary intake or exhaust in cases with hotter components. The noise level 10 - 36 dBA gives a reasonably quiet profile, especially at lower speeds and with the correct fan curve in BIOS or software. The magnetic bearing helps for longer life and smoother operation compared to standard sleeve or ball bearings.

• 140 mm size – standard format for modern cases and radiators, providing better air flow than 120 mm at the same RPM.
• 1700 RPM PWM control – gives you flexibility to tune the profile from almost silent idle to aggressive cooling during gaming or rendering.
• Air flow 17.9 - 94.7 CFM – wide range that covers both quiet builds and systems with powerful GPU and CPU that heat more.
• Static pressure 0.15 - 3.75 mm-H2O – suitable for mounting on top of a radiator or dense front panels/filters where you need to "push" air through resistance.
• Noise level 10 - 36 dBA – allows almost silent operation at low speeds and controllable noise at maximum performance.
• Magnetic Bearing bearing – smoother and quieter operation over time, with less vibration and higher reliability.
• Addressable RGB lighting – gives you individually controllable light effects for finer tuning of the build's visuals.
• 4 PIN connector and 12 V power – standard PWM connection, easy to integrate with most motherboards and fan controllers.
• Black chassis – stands well in almost any build, especially if you are looking for a cleaner, darker look with an RGB accent.
• 36 months warranty – you have three years of peace of mind at 24/7 load or long gaming sessions.

Who it is suitable for
It is suitable if you are looking for a 140 mm fan for a mid/high-end gaming configuration, custom water with radiator or just want to increase air flow in the case without sounding like a vacuum cleaner. If you are chasing an extreme silent build at minimal RPM, you might want to combine it with more fans at lower speed, instead of relying on just one. It is also a logical choice if you are already in the Corsair ecosystem and need another RX140 RGB as an expansion.

The most sensible here is the combination of 140 mm format, wide range CFM/pressure and magnetic bearing, plus addressable RGB for visuals. If you want a fan that is equally convenient for case and radiator and you can tune it exactly as you need, this model fits well.
