Razer Kunai Chroma, 140mm, PWM, Hydraulic Bearing, ARGB Fan Kit, 3-pack, Black

These 140mm case fans feature nine optimized blades designed for system cooling efficiency in standard computer chassis installations. Rotation speed is precisely controlled via a 4-pin PWM connection, ranging dynamically from 500 RPM up to 1500 RPM, allowing adaptation to current thermal loads. At maximum performance, the units deliver an airflow rating of 103.43 CFM alongside an air pressure of 1.04 mmH2O. Operational acoustics are managed effectively, generating a noise output between a quiet 21 dB at low speed and 35 dB under full load.

The fans are constructed with a durable plastic frame and rely on hydraulic bearing technology, promoting longevity with a specified Mean Time Between Failures (MTBF) of 60,000 hours. Each unit measures 140 mm wide and 26 mm deep, fitting standard case mounting points. Addressable RGB illumination is integrated, featuring 22 LEDs per fan, controlled via a dedicated 3-pin (5V) connector, which requires the use of specific host software for configuration and synchronization. This specific model is supplied as a three-unit package for comprehensive chassis ventilation projects.
