Cryorig’s proprietary Quad Air Inlet system features four strategically placed aerodynamic air inlets that allow for extra air intake. The additional air intake enables the QF Series fan to achieve a higher air output volume for its fan diameter, resulting in better temperatures for your CPU heatsink and more air exchange for your system case.

Pleasing your ears with acoustic engineering, QF Series PWM fans feature Cryorig’s HPLN (High Precision Low Noise) bearing system, offering stable and precise rotation while eliminating excess vibration and noise.

With an ultra-wide RPM range, you can fine-tune your fan profile. Featuring four-pin Pulse Width Modulation (PWM) RPM spin speed control, QF Series fans provide an extensive range of RPM settings. This wide RPM range allows users to adjust their fan speed directly through mainboard BIOS settings, offering roughly 33% more selection range than competitor system fans, with some RPM speeds only available through PWM control.

Vibration absorbers are included to soak up every last bit of noise. Frame vibration can cause unwanted noise, which is why all QF Series fans come with rubberized vibration absorbers to nullify fan vibration. These absorbers are built directly into the fan frame, requiring no extra work.

Silent operation is achieved with ultra-low RPM speeds of 200 to 1000 RPM, maintaining a minimum noise level of 5 dBA. This is almost on the threshold of human hearing and virtually inaudible inside a PC chassis while still pushing airflow. It is the perfect solution for midnight gamers or audiophiles who need near silence while keeping their system cool and stable.
