The P12 SLIM PWM PST has an installation height of 15mm, making it suitable for small form factor cases & for installations for which a 25mm fans cannot fit. The high static pressure fans, guarantee efficient cooling, even with increased air resistance. Suitable for use on heat sinks, radiators and even case fans. Using the 4-pin PWM connector, the fan speed of 300 to 2100 RPM can be controlled via PWM PST. This keeps noise to a minimum while at the same time ensuring maximum cooling performance.
