Arctic P14 Pro PST PWM Fan Kit, Fluid Dynamic Bearing, 140mm, 5-pack, Black

The 140 mm cooling fan is engineered for effective thermal management within computing enclosures, suitable for both case ventilation and radiator deployment. It operates across a broad speed range, running from a low of 400 RPM up to a maximum of 2500 RPM. This rotational capability allows the unit to deliver a peak airflow rating of 110 CFM, equivalent to 186 m³/h. The design prioritizes static pressure, generating 5.2 mmH₂O, which ensures optimal heat dissipation even through restrictive cooling apparatus or dense filters.

Stability and noise control are managed via a Fluid Dynamic Bearing (FDB), utilized to minimize mechanical friction and ensure extended operational life. The acoustic output is controlled, registering 25 dB at its highest rotational speed. The unit integrates a 4-pin connection supporting Pulse Width Modulation (PWM) control, allowing the system to regulate speed dynamically based on thermal load requirements. Furthermore, the inclusion of a daisy-chain connection mechanism allows multiple fans to synchronize control signals from a single motherboard header. This model is packaged as a five-unit set, providing components for comprehensive system cooling solutions.
