OPTIMISED FOR STATIC PRESSURE: Through high static pressure, the fan guarantees efficient cooling, even with increased air resistance. Suitable for use on heat sinks and radiators STRONG COOLING PERFORMANCE: The performance of the P fans has been noticeably increased through numerous improvements, including upgraded engine technology and a newly developed fan design 300 TO 2100 RPM: Thanks to the 4-pin connector, the fan speed can be controlled via PWM PST. This keeps noise to a minimum while at the same time ensuring maximum cooling performance LOW INSTALLATION HEIGHT: The P12 Slim PWM PST has an installation height of only 15 mm, making it suitable for small form factor cases & for installations for which a 25 mm fan does not fit TECHNICAL DATA: 3 Pack, Fan speed: 300–2100 RPM, Airflow: 71.53 m³/h/41.1 CFM, Noise Level: 0.3 Sone, Static Pressure: 1.45 mm/H2O, Pin: 4-pin
