Fan accessory set consisting of three NA-YC1 Y cables that enable two 4-pin PWM fans to operate on one fan header and allow the motherboard to control the speed of both fans simultaneously.

Multiple NA-YC1s can be daisy-chained to control more than two PWM fans through one header. The 4-pin connectors of the NA-YC1 are compatible with both 3-pin and 4-pin PWM fans, but PWM control is only supported with 4-pin fans. Thanks to the black housing, the cables are ideal for creating computer builds with a neat, focused aesthetic and perfectly match Noctua chromax edition enthusiasts.
