3PIN CPU fan deceleration line, supports 3PIN interface fans, can effectively reduce fan noise, solve the problem of too high speed and too much noise. Reduce the fan speed, reduce the noise of the CPU fan, and extend the service life of the fan. PVC insulation, all copper wire core conductive, fast speed, stable transmission, not easy to oxidize, anti-interference, long service life. The connectors are wrapped with heat shrink tubes to protect the wire from oxidation, and not cause poor contact due to bending, and still good stability after long-term use. Product interface: - end motherboard small 3pin connector, the other end is the fan small 3Pin interface Product function: reduce the speed of the computer fan and reduce fan noise. Colour:Black Material:PVC+Copper Size:Length: about 13cm Package Contents: 1 x Fan Speed Reduce Cable Only the above package content, other products are not included.
