Blacknoise BlackSilentPro PE-P 92mm 1800rpm PWM case fan

92mm PWM case fan for quiet builds

The Blacknoise BlackSilentPro PE-P is a 92mm case fan designed for systems that prioritise low noise. It targets builders who want a compact axial fan with PWM control and a 20 dBA acoustic rating. The 1800 RPM maximum speed delivers 38.26 ft³/m of airflow while keeping sound output minimal. Users needing larger diameters or higher static pressure for dense radiators should look elsewhere.

38.26 ft³/m airflow at 1800 RPM

At full speed the fan moves 38.26 ft³/m of air, which is sufficient for moderate component cooling or general chassis ventilation. The 20 dBA noise level remains low even under load, leaving headroom for quiet operation. Demands such as high-restriction water-cooling radiators or heavily overclocked hardware will exceed what this airflow figure can sustain. The 4-pin PWM connector allows the motherboard to scale speed down when thermal load is light.

NANO-SLI bearing with textile-sheathed cables

A NANO-SLI magnetic bearing and NB-EKA-P2 drive provide low start-up voltage and long-term reliability. The frame measures 92mm by 92mm by 25mm and is made from reinforced fibreglass PBT with a Bayer Makrolon rotor that resists dust buildup. Included are 20 cm and 50 cm cables wrapped in textile sheathing, plus a screw set and a silicone sealing frame for vibration-free mounting. No LED lighting is present, keeping the appearance understated.
