Pay attention to functions and branch cables that can control multiple fans and LED devices
PC cases with multiple LED-equipped fans that sell for more than 20,000 yen are often equipped with a “fan/LED hub.” This is a feature that allows multiple fans and LED devices to be controlled by a single fan/LED connector on the motherboard.
[POINT!]Products with fan/LED hubs are also popular
Larger PC cases that can accommodate many case fans often include these fan/LED hubs to control multiple fans and LED devices together.
These fan/LED hubs can also be purchased separately. If you want to incorporate a large number of fans and illumination parts and freely control them from the utility, you should use these functions and devices. Also, if one more connector is missing, one way is to purchase a “branch cable” for the fan or LED and increase the number of connectors.

Branch cable that can connect up to 3 addressable LED compatible devices and control them together
Match fans with the same model, and pay attention to port restrictions for LED devices
If you want to control them together, connect fans with the same specifications. If the number of revolutions and sizes are different, the number of revolutions and operating noise of the fan will change depending on the supplied voltage, and it will not be possible to control it correctly. LED connectors also have limits on the length they can control and the current they can provide, beyond which the LED may not light up.
Some combinations cannot be controlled correctly

When connecting fans with different fan speeds or sizes, the speed of each fan cannot be maintained at its optimal state.

The number of LEDs that can be controlled and the length of the LED strip are specified for the LED connector mounted on the motherboard.
