These 30cm extension cables allow you more choice in where you want to position your PWM or standard 3 pin fans inside your case.

The wires are 30cm sleeved in black braiding with a 4pin female connector at 1 end and splits to 2 4pin male connectors at the other.

Please ensure your motherboard fan header is capable of the additional electrical load before purchasing any of these.

Please note - all the connectors are 4 pin connectors , but one of the connectors only has 3 wires. The reason for this is that the sensor wire is not used on this connector as if both fans were sending back information to the motherboard it would not be able to understand the information as both lots of information would be coming back through the single connector.

What happens is the fan with all 4 wires tells the mobo the information , and then the mobo controls the speed of both fans.

These do also have a cut out so you can use 3 pin fans instead of 4 pin if you wish.
