This model utilises a rifle bearing for durability and operates quietly even at higher speeds. Because it supports PWM, you can control fan speeds dynamically based on system temperatures. The all-black finish ensures a stealthy look when the LEDs are off, while the multi-colour illumination offers customisation options.

Key Performance Metrics

Optimised Intake Aesthetics

The reverse blade orientation is specifically engineered for intake positions. In practice, this means the fan motor hub is visible from the viewing side, creating a cleaner, more uniform lighting effect in your case. Standard fans often show the motor support struts, which can disrupt the visual flow of ARGB lighting.

Efficient Cooling Performance

With a maximum airflow of 51.4 CFM and a static pressure of 1.1 mmH₂O, this fan handles case ventilation effectively. It is suitable for mounting on side or bottom intakes where unobstructed airflow is prioritised. The rifle bearing technology contributes to a long lifespan of up to 60,000 hours MTTF, ensuring reliable operation over time.

Quiet Operation with PWM Control

The fan operates at a noise level of just 25.5 dB(A) at maximum speed, which is notably quiet for a 140 mm fan. Because it supports 4-pin PWM, your motherboard can automatically adjust the speed to balance cooling performance with acoustic comfort. This prevents unnecessary noise during low-load tasks like web browsing.

Vibrant ARGB Lighting

This unit features multi-colour LED illumination, allowing for synchronisation with compatible ARGB controllers. The lighting is designed to be impressive from every angle, enhancing the interior of your PC case. If you prefer a minimalist setup, the LEDs can be turned off while retaining the fan’s cooling capabilities.
