Features: 100% brand new and high quality With this line, you can make the 4-pin interface on the motherboard simultaneously PWM speed control / speed control / temperature control PWM fans, such as radiators with dual fans or 4 fans Allows the fan to achieve a quiet effect and dissipate heat. One 4-pin CPU cooler and three 4-pin chassis fans, then all three fans will adjust speed as CPU temperature changes. The advantage is to maintain a balance of airflow. Provide 4Pin PWM fan interfaces to support multiple 4Pin PWM fan automatic speed regulation. The black snakeskin bundle design is adopted to facilitate the overall wiring inside the chassis and improve the overall aesthetics. Easily implement 4Pin PWM temperature control fan parallel connection, making full use of a limited number of motherboard 4Pin interfaces. Package Includes: 1 x 4Pin Fan Splitter Computer PC Fan Power Cable Specifications: Product Name: Motherboard Fan 4Pin PWM Extension Cable Product Length: about 27cm / 10.63 inches Wire Model: 1007 24AWG Conductor Specification: 11/0.12 Conductor Material: Tinned Copper Wire Color: Black Style: 4 Way ( 1 to 1 / 1 to 2 / 1 to 3 /1 to 4) Optional Product function: make computer fans share one motherboard PWM 4-pin socket note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
