Model PWM

  • Focused Flow frame delivers high static pressure for heatsinks and radiators
  • PWM control enables automatic 300-1500 RPM speed range via motherboard headers
  • SSO2 bearing rated >150000 hours MTTF for long service life
  • Low-Noise Adaptor reduces maximum speed to 1200 RPM and noise to 18.60 dBA
  • Modular cabling kit includes Y-cable, extension cable, anti-vibration mounts and screws

Purpose-Built for High-Resistance Cooling

The NF-F12 PWM is a 120 mm case fan engineered for pressure-demanding tasks such as CPU heatsinks and water-cooling radiators. Its Focused Flow frame uses eleven stator guide vanes and a seven-blade impeller to concentrate airflow where resistance is highest. Builders who need a single fan for unrestricted case ventilation will find simpler, cheaper options elsewhere.

Airflow Range and Practical Headroom

Maximum airflow reaches 54.97 CFM at 1500 RPM, while the supplied Low-Noise Adaptor caps speed at 1200 RPM for 43.73 CFM. PWM control permits operation down to 300 RPM for near-silent idle. The fan runs out of static pressure when faced with extremely dense fin stacks or dual-radiator stacks that demand still higher pressure curves.

Thermals, Acoustics and Power Draw

At full speed the fan produces 22.4 dBA, dropping to 18.6 dBA with the Low-Noise Adaptor fitted. The second-generation SSO2 bearing and custom PWM IC keep the sound signature smooth across the 300–1500 RPM range. Anti-vibration pads and compensators decouple the 25 mm thick frame from the chassis, preventing resonance that would otherwise raise perceived noise.

Questions about this item

Will the 120mm 25mm frame and 4-pin PWM connector fit my existing case fan mounts and motherboard headers?

The fan measures 120.00 x 120.00 x 25.00 mm and uses a standard 4-pin PWM power connector, so it fits typical 120mm case mounts and 4-pin motherboard headers.

How can I verify the fan is running at the correct 300-1500 RPM range after installation?

Use your motherboard BIOS or fan-control software to monitor the reported RPM; the fan should read between 300 RPM minimum and 1500 RPM maximum depending on the PWM duty cycle.

Does the box include mounting hardware and cables, or do I need to buy screws and a PWM Y-cable separately?

The package contains four vibration-compensators, four fan screws, a 30cm extension cable, a 4-pin Y-cable and a Low-Noise Adapter, so no extra mounting parts or cables are required.
