Key Features
- 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
