Noctua 120mm， Anti-Stall Knobs Design，SSO2 Bearing PWM Case Cooling Fan NF-S12A PWM[Product Information]- Enter your model numberto make sure this fits.
- The NF-S12A features the third evolution of Noctua's classic Straight Blade Design that achieves 10 cfm
- The NF-S12A's Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations n thereby increase the fan's stall margin， that is even more versatile than its renowned predecessor .
- Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures， both of which further refine the fan's performance/noise efficiency.
- Noctua's Stepped Inlet Design adds turbulence to the influx to facilitate the transition for laminar flow to turbulent flow， that reduces tonal intake noise， improves flow attachment， incur suction capacity， especially in space restricted environments.
- Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
