The F12 PWM PST is a case fan from Arctic that offers efficient cooling thanks to its size of 120 mm. The fan adapts its speed to the required system performance and works at a very low volume even under full load. For a particularly high level of efficiency, the fan can also be switched synchronously with other fans built into the housing. The fan is kept in a simple black and accentuated by white elements on the fan hub.The features of the Arctic F12 PWM PST fan at a glance:- Large 120 mm fan for efficient cooling performance- Dynamic fan speed thanks to PWM technology- PWM sharing technology for synchronizing several fans- Very good cooling performance with up to 1,350 rpm- Barely noticeable operation at only 23.5 dB (A)- Durable fluid dynamics bearing- Ten year guaranteeGood cooling performance with very quiet operationThe Arctic F12 PWM PST has a very good cooling capacity thanks to its size and rotation speed of up to 1,350 rpm . With a volume of just 23.5 dB (A) , the fan is also barely noticeable and is therefore ideal for computer systems that are designed for quiet operation. The fan generates a static pressure of 1 mmH2O and a delivery volume of 91.1 m / h (53.61 cfm) in order to either conduct heat effectively out of the system or to draw in cold air to cool components from the outside.Equipped with a pulse width modulationthe fan only turns as fast as the current system performance demands. This guarantees consistently quiet operation. The PWM sharing technology synchronizes several fans in the housing with each other, so that background noise is minimized.The fan is kept in simple black and accentuated by white elements on the fan hub. In order to ensure long-term operation, a hydrodynamic slide bearing was installed, which is characterized by a long service life. In the event that unforeseen complications should arise, Arctic gives a ten-year guarantee .Technical details:- Dimensions: 120 x 25 x 120 mm (W x H x D)- Weight: 109 g- Colour: Black- Material: Plastic- Bearing: hydrodynamic plain bearing- Volume: 0.3 sone / approx. 23.5 dB (A)- Speed: 230 - 1,350 rpm- Delivery volume: 90.1 m / h (53.61 cfm) - Static pressure: 1 mmH2O- Voltage: 12V- Starting voltage: 6 V- Amperage: 0.24 A.- Connection: 4-pin PWM- Cable length: 400 mm- Manufacturer\'s guarantee: 10 years
