It is for this reason that the fan blades of Silent Wings Pro 4 120mm PWM have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks.\u003c\/p\u003e\u003cp\u003eSilent Wings Pro 4 120mm PWM makes for extraordinary air pressure and therefore, significantly increases the system's performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 120mm PWM allows the user to run even the most demanding applications.\u003c\/p\u003e\u003cp\u003eThe speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 120mm PWM alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds.\u003c\/p\u003e\u003cp\u003eSilent Wings Pro 4 120mm PWM has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.\u003c\/p\u003e\u003cp\u003eThe advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings Pro 4 120mm PWM.\u003c\/p\u003e\u003cp\u003e6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.9dB(A).
