Features: Good quality wire, easy to bend, strong toughness, and wear-resistant. The interfaces according to standard connection port Specially for serious gamers and computer enthusiasts who require reliability. After the transfer - connect a 4Pin PWM fan, and the graphics card will automatically adjust fan speed according to the heat generated After transfer - connect a 3Pin fan fan will rotate at fullspeed because 3Pin doesnot have PWM speed control function. To achieve PWM speed control of the graphics card fan, fan is a 4Pin PWM speed control fan. If fan interfaces on the graphics card is a 4Pin interfaces, then there will be PWM speed control fan function If fan interfaces on the graphics card is a 3Pin interfaces, there is not PWM speed control fan function, and this cable cannot be used on your graphics card. Before purchasing, please confirm your graphics card interfaces type. Specifications: Material: PVC Length: about 15cm/5.9in Connection: Small 4pin to 3Pin 4Pin Cable Package Includes: 1PC Small 4pin to 3Pin 4Pin Fan Cable note: 1.Transition: 1cm=10mm=0.39inch 2.Please allow 0-1cm error due to manual measurement. please make sure do not mind before bid. 3.Due to the differences between different monitors, the picture may not reflect the actual color.
