Extra Performance
Quad Air Inlet™

CRYORIG’s proprietary Quad Air Inlet™ system features four strategically placed aerodynamic air inlet that allows for extra air intake. The additional air intake allows the QF Series fan to have a higher air output volume for its fan diameter, which equals better temperatures for your CPU heatsink and more air exchanged for your system case.

Pleasing Your Ears
With Acoustic

QF Series PWM fans feature CRYORIG’s HPLN™ (High Precision Low Noise) bearing system, offering stable and precision rotation eliminating excess vibration and noise.

Ultra Wide RPM Range
Fine Tune Your Fan Profile

Featuring four pin Pulse Width Modification (PWM) RPM spin speed control, QF Series fans offer a ultra wide range of RPM settings.  This wide RPM range allows users to fine tune their fan speed directly through mainboard bios settings.  Roughly 33% more selection range than the system fans from competitors.  *some RPM speeds are only available through PWM control.

Vibration Absorbers
Included Soaking Up
Every Last Bit of Noise

Frame vibration causes unwanted noise. This is why all QF Series fan come with rubberized Vibration Absorbers to nullify fan vibration. Vibration Absorbers are already built directly into the fan frame, no extra work necessary.

Choose Your Model

The QF Series in three different flavors: Silent, Performance and Balance.


Ultra low RPM speeds of 200~1000 RPM with the near silent noise level of 9 dBA, it is almost on the threshold of human hearing and virtually inaudible inside a PC chassis, while still pushing large amounts of airflow thanks to it’s massive 140mm wingspan. The perfect solution for mid-night gamers or audiophiles, who need near silence but still their system cool and stable.


600~1850 RPM combining our large 140mm fan blade grants extreme airflow and performance. Connect it directly to your mainboard or a PWM capable fan controller to access the ultra-wide RPM range. 600 RPM provides great noise to performance ratio, at the same time keeping great system airflow. Once unleashed, the max 1850 RPM nearly double the airflow of regular 140mm sized fans and enough cooling force for even the most heated systems.
