## Summary description

Cryorig QF140 Silent is a 140 mm case fan designed for low-noise PC cooling. It operates between 200 and 1000 RPM, producing 9–19.5 dB noise, with maximum airflow of 42.1 CFM and static pressure up to 1.06 mmH2O. The fan measures 140×140×25.4 mm, weighs 0.1593 kg and comes in black—suitable for chassis ventilation, radiators or intake/exhaust configurations.

## Long description

The Cryorig QF140 Silent 140 mm is a case fan engineered for low-noise PC cooling with balanced airflow and static pressure. It operates between 200 and 1000 RPM, delivers up to 42.1 CFM of airflow and generates noise in the range of 9–19.5 dB. The fan has a 140×140×25.4 mm form factor, weighs 0.1593 kg and is finished in black. Cryorig’s Quad Air Inlet™ and HPLN™ bearing technology combine to increase intake efficiency and provide stable, low-vibration rotation suitable for chassis ventilation, radiator mounts and intake/exhaust configurations.
Advantages
The Quad Air Inlet™ design increases effective air intake for a higher air output relative to the fan diameter. HPLN™ (High Precision Low Noise) bearings reduce rotational noise and vibration, while integrated rubberized vibration absorbers further limit frame-transmitted noise. A wide PWM-controlled RPM range (200–1000 RPM) allows fine tuning from near-silent operation to higher airflow when needed. The fan’s combination of up to 42.1 CFM airflow and 1.06 mmH2O static pressure makes it versatile for both unrestricted chassis airflow and moderate-restriction radiator setups.
Suitable for
Case ventilation in compact and mid-tower systems
Intake or exhaust fan positions to balance airflow
Mounting on radiators or heatsinks requiring moderate static pressure
Quiet or noise-sensitive builds such as home office or media PCs

How to use
Install the Cryorig QF140 Silent in a standard 140 mm fan mount on the case chassis, radiator or heatsink using the supplied screws or compatible mounting hardware. Connect the 4-pin PWM cable to a motherboard fan header or fan controller that supports PWM to enable variable speed control. Configure fan speed curves in BIOS or software to match desired cooling and noise levels; lower RPM values provide near-silent operation while higher RPM values increase airflow. Ensure the fan orientation matches the intended airflow direction for intake or exhaust.
Usage recommendations
For quiet systems, set default BIOS fan curves to keep the fan near the 200–400 RPM range during light load and allow higher RPM under sustained load. When using on radiators, position the fan to minimise air restriction between the radiator fins and the fan frame and use PWM control for dynamic response. Periodically clean dust from the fan blades and airflow paths to maintain performance and low noise.
