4 Pin power supply pass through to 3 Pin fan power cable, 30cm (RB-523)

This is a 15cm long cable which can connect a standard 3 pin PC case fan or CPU fan to a normal 4 pin PC power supply outlet. It also features a 4 pin power supply pass through so it does not use up a power supply outlet. The cable can be used for systems which have more fans than fan power points on the motherboard or where the fan cable is too short to reach the motherboard power outlet.
