HAVN H14, 140mm, PWM Fluid Dynamic Bearing Fan Kit, 3-pack, White

This product provides a set of three 140 mm computer cooling fans engineered for both case ventilation and integration with liquid cooling radiators. The fans are managed via a 4-pin Pulse Width Modulation (PWM) connector, facilitating dynamic speed control to match current cooling load demands. Operational speed can be regulated across a range, starting from 0 RPM up to a maximum rotational velocity of 1600 RPM. When operating at peak performance, the system delivers a maximum airflow of 85.18 CFM and generates 2.19 mmH₂O of static pressure.

The unit incorporates a Triple-Groove Fluid Dynamic Bearing (FDB) system designed to maintain stable axis rotation and contribute to long-term reliability. Construction materials include PBT plastic reinforced with 30% glass fiber, providing structural integrity and minimizing resonance. For streamlined system building, the fans utilize a Loopin daisy-chain cable structure, which features male-female pass-through connectors to link multiple units using a single header connection on the motherboard. The physical dimensions of the fan are 140 mm wide and 30 mm thick.
