Power up to 10 PC fans from a Single 4-Pin Motherboard PWM Fan Header.Note: Max current limit is 3A in total, check the spec of fan first..
In the hub interfaces, the White interface of FAN1 is the CPU fan dedicated interface (with speed detection function). Since the mainboard can only receive one rotation speed signal, the remaining nine conventional fan interfaces have the PWM function, but no speed signal..
There is EVA double-sided adhesive in the package, which can be easily affixed to a flat place. Also a fixing screw hole in the middle of the PCB to facilitate fixing to a part of the chassis..
Direct computer power supply to reduce the mainboard loading pressure, and PWM temperature control line separated from mainboard to achieve both of power supply and temperature control..
If 3-pin fans are connected to this fan hub, this fan hub CANNOT give them extra PWM function. They will run at FULL SPEED..

... GIFT SHOW AND WEDDING FAVOR: You can use this fan for everyday use, gifts, wedding decorations, family room decoration, collection, DIY crafts, photo props and stage props, etc.There is a tassel of different colors under each fan to make the fan look more classical and elegant..
SAFTY PACKING: each fan is pack with single opp plastice bags. Then it repacked with paper box. You don't worry aobut it will be damaged during shipping. In case of damage, you can find us and we will replace it for you free of charge..
WARMEST NOTICE: Since the wood fan material of each batch is different, there will be a little difference in the color of the natural wood. However, the color of the fan page of the single fan is guaranteed to be the same. If you mind, please consider it carefully..
