4 / 3 Pin PWM Fan Y Splitter 14cm Extension Cable Lead hub. 1 to 2 3 4. CPU. UK.

The splitters only have all 4 pins on one of the male connectors, the rest have 3, this is normal for these cables. The motherboard can only take fan speed from 1 fan, so the cable for monitoring fan speed is only on 1 connector.
