What customers say
This fan earns high praise primarily for its superior performance and acoustic profile. Users consistently highlight the Magnetic Levitation bearing technology, noting its exceptional longevity and near silent operation, especially at moderate speeds. These fans effectively move significant air while maintaining a remarkably low noise level, making them perfect for demanding systems. Build quality is robust, reinforced by effective anti-vibration features. The clean white LED lighting adds a sophisticated aesthetic. While the premium price point is a consideration for some, enthusiasts recognize the investment in top-tier cooling and reliability. Overall, it is highly recommended for users prioritizing maximum performance and minimal noise.
Know before you buy
Magnetic levitation technology allows the fan rotor to float, which significantly reduces friction compared to traditional sleeve or ball bearings. This results in quieter operation, less wear over time, and higher performance at both low and high speeds.
Yes, this fan uses a 4-pin PWM connector, which allows you to precisely control the speed via your motherboard's BIOS or fan control software. It supports a wide range from 400 RPM for silent idling up to 2,000 RPM for maximum cooling.
Absolutely. The custom rotor design is engineered to provide high static pressure, making it an excellent choice for pushing air through the restrictive fins of a radiator or a dense heatsink.
The fan includes rubber dampers at the mounting points that absorb vibrations before they can transfer to your PC case. The corners are replaceable, allowing you to swap them out if you want to customize the look of your build while maintaining silent operation.
The white LED provides a clean, consistent glow that is integrated directly into the fan housing. While brightness is subjective, it is designed to be a subtle accent rather than an overwhelming light source, though it cannot be dimmed or turned off independently of the fan speed.
