The Chieftec AF-1225PWM is a 120mm black PC case fan designed to maintain optimal temperatures within your computer system. It utilizes a ball bearing system to ensure stability and a lifespan of up to 50,000 hours, making it a reliable choice for long-term use. With a maximum speed of 1650 rpm and a static pressure range of 1.2 to 1.6 mm/H2O, it effectively pushes air through heatsinks or restrictive case filters. To give you control over your system's acoustics, the fan features PWM functionality, allowing the motherboard to adjust the speed based on thermal needs, while keeping noise levels between 29 and 32 dBA. It offers flexible installation options through both a 4-pin PWM connector and a Molex plug, with cables measuring between 29 and 32 cm. Weighing approximately 139g, this unit comes with a set of mounting screws and carries CE, RoHS, EAC, TUV, and UL certifications for safety and quality standards.
