Fan ENDORFY Fluctus 140 PWM ARGB - Black

ENDORFY Fluctus 140 PWM ARGB is a 140 mm case fan aimed at more meaningful, well-ventilated configurations, where you seek a balance between airflow, noise, and aesthetics. It operates with PWM control and a wide range of 250 – 1800 RPM, giving you flexibility – from almost silent operation to serious cooling under load. The built-in Addressable RGB lighting allows you to connect it to the motherboard's ARGB ecosystem and create a synchronized build. The black color and standard thickness of 25 mm make it a universal choice for most cases.

What you get

With a size of 140 x 140 x 25 mm, this fan covers more area than standard 120 mm fans and can move up to 48.8 CFM of air, which is more than enough for decent front intake or exhaust in mid-tower and larger cases. The bearing is FDB (Fluid Dynamic Bearing), which means better durability and lower noise compared to cheaper sleeve solutions, especially at higher speeds. Through the 4-pin PWM connector, you can adjust fan curves through the BIOS or motherboard software – for example, slow speeds at idle and aggressive cooling during gaming. 12 V power ensures standard compatibility with most modern motherboards and controllers.

• Size 140 mm – a larger fan for better airflow at relatively low speeds, ideal for intake or exhaust in larger cases.
• Range 250 – 1800 RPM – gives you the option for a quiet mode under low load and serious cooling when the CPU and GPU heat up.
• Airflow 48.8 CFM – sufficient for stable air circulation in gaming configurations and systems with more drives or more powerful components.
• FDB bearing – smoother rotation, less vibration, and longer life compared to standard sleeve bearings, especially under 24/7 operation.
• 4-pin PWM connector – full control over speeds through the motherboard or controller, without relying on fixed speeds.
• Addressable RGB (ARGB) lighting – individually addressable lights for synchronization with other ARGB equipment and a clean visual build.
• 72 months warranty – a long warranty period that indicates the fan is designed for long-term use in a main system.

Who is it suitable for? This fan is a good choice if you are building a gaming or workstation machine and want a 140 mm solution with PWM control and ARGB, without entering extreme prices. It is also suitable for quieter builds, where you keep the fans at low speeds and rely on the larger size for airflow. It is not the optimal option if you are looking for a completely clean build without any lighting – here ARGB is part of the idea.

The combination of 140 mm format, FDB bearing, wide RPM range, and Addressable RGB makes ENDORFY Fluctus 140 PWM ARGB a practical fan that cools reliably and looks good at the same time. With a 72-month warranty, you can confidently plan it as a long-term element of your case.
