Razer Kunai Chroma PWM ARGB Fan, Hydraulic Bearing, 140mm, Black

This 140 mm cooling fan is engineered for optimal temperature regulation within desktop computer systems. Operation is controlled via a 4-pin PWM interface, enabling rotational speeds from 500 RPM up to a maximum of 1600 RPM. The unit provides a maximum airflow rating of 81 CFM and a static pressure peak of 1.31 mmH2O. These specifications support efficient heat exhaust and intake when installed within the computer chassis.

Acoustic output of the fan ranges from 15 dB at minimum speed to 30 dB under full load conditions. The internal hydraulic bearing mechanism is rated for a Mean Time Between Failures (MTBF) of 60,000 hours, supporting long-term component stability. The fan integrates addressable RGB illumination, utilizing 22 individual LEDs for visual customization. Installation is simplified by the inclusion of mounting screws, and the fan supports daisy-chain connectivity for synchronizing up to eight units.
