Fan Corsair iCUE LINK LX140 RGB 140mm PWM Single Fan Expansion White - CO-9051031-WW

This Corsair iCUE LINK LX140 RGB is a 140 mm PWM fan that can easily handle the role of both a case cooler and a radiator fan. It impresses with a wide speed range of 350 – 2000 RPM, so you can tune it from a nearly silent mode to aggressive cooling. The white color and Addressable RGB lighting make it suitable for a build where the look is as important as the temperatures. This is a single fan expansion, ideal if you are already in the iCUE ecosystem and want to upgrade.

What you get: A fan with dimensions of 140 x 140 x 25 mm, which combines high airflow of up to 84.7 CFM with good static pressure of up to 4.86 mm-H2O – exactly what you need for both front intake through filters and mesh, as well as for a dense radiator. The range of 10 - 36 dBA allows for a tight profile for silence at idle and a more aggressive curve under load. The Magnetic Bearing helps for smoother operation and a long lifespan, while the PWM 4 PIN connector gives you fine control via the motherboard or controller. Operation at 12 V and consumption of up to 0.45A are standard for a powerful 140 mm fan, so they will not surprise your PSU.

• 140 mm size offers greater airflow at lower speeds compared to 120 mm, which is a plus for a quieter system.
• Speed 350 – 2000 RPM ±10% gives you flexibility – from nearly silent rotation to serious cooling when needed.
• Airflow 10.74 - 84.7 CFM is sufficient for both main intake/exhaust and for supplying a dense radiator with fresh air.
• Max. pressure 0.11 - 4.86 mm-H2O makes it suitable for mounting on radiators or behind dense filters, where it needs to “push” the air.
• Noise level 10 - 36 dBA ensures quiet operation at low speeds and controllable noise at maximum cooling.
• The Magnetic Bearing is designed for smoother rotation and less friction in the long term.
• Addressable RGB lighting and a white housing make the fan an excellent choice for visually finished, thematic builds.
• 4 PIN PWM connector at 12 V with 0.45A consumption guarantees wide compatibility with modern motherboards and controllers.
• 60-month warranty gives you peace of mind for long-term operation.

Who it is suitable for: If you are building a white or RGB-focused build and want 140 mm fans that can cover both case and radiator duties, this model is a logical choice. It is suitable for gaming and enthusiast configurations where you want a balance between cooling and noise, plus synchronized lighting. It is not the most sensible option if you are only interested in “the cheapest fan without lights”.

The combination of a wide RPM range, serious CFM and static pressure, plus Addressable RGB and a 60-month warranty, makes this Corsair LX140 RGB a very solid foundation for a well-cooled and visually tight build.
