ARCTIC BioniX P140 PWM Fan, Fluid Dynamic Bearing, 140mm, Grey

The ARCTIC BioniX P140 is a 140 mm cooling fan engineered primarily for applications demanding high static pressure, such as liquid cooling radiators or densely finned heatsinks. It utilizes a five-bladed design optimized specifically for focusing airflow rather than maximizing volumetric flow across minimal resistance. The unit operates within a rotational speed range of 200 RPM up to a maximum of 1950 RPM. This rotation capability allows the fan to achieve a maximum static pressure of 2.85 mmH2O, suitable for overcoming significant thermal resistance within a constrained system environment.

Speed control is managed through the 4-pin fan connector, utilizing Pulse Width Modulation (PWM) support for precise operational adjustments based on system requirements. This model features integrated PWM Sharing Technology (PST), allowing multiple fans to synchronize their speed profiles from a single control signal. Component longevity is addressed via the use of a Fluid Dynamic Bearing, which minimizes friction and wear compared to standard sleeve bearing implementations. The unit maintains a perceived loudness level of 0.45 Sone, requiring 12 V DC and consuming a total power of 1.8 watts during typical operation.
