4pin PWM spliter 1*4 HUB product
4pin PWM spliter 1*4 HUB
[Product name]: 4Pin one-to-four fan connected to the extension cable (this interface can be used for 3Pin and 4Pin)
[Product length]: 27cm
[Wire Model]: 1007 24AWG
[Insulation material]: PVC insulation
[Conductor specifications]: 11*0.12TS
[Conductor material]: tinned copper
[Outer diameter of wire]: OD1.4mm
[Rated temperature]: 80℃
[Wire color]: black
[Product weight]: 20 grams
[Product interface]: One end is a small 4pin connector that connects to the motherboard, and the other four ends are a small 4Pin interface that connects to the fan
[Product function]: Make 4 computer fans share one interface
Purpose: This product can be used when the CPU plug (4Pin) on the motherboard is not enough and the chassis fan cable is not long enough. Mainly to extend and expand the motherboard three-pin four-pin interface. important: In order to avoid signal conflicts for simultaneous speed measurement, there are two default speed measurement lines. That is to say, of the 4 ports separated, one of them is 4 needles (supporting speed measurement and temperature control), and the other 3 are 3 needles (only supporting temperature control).
Reason: Because even fans of the same model may have different speeds, using a pin on the motherboard to measure two or more fans with different speeds at the same time will cause the motherboard to strike.
The result is that the two interface PWM and speed measurement functions are both invalid. Therefore, it is necessary to remove a speed measurement line of other interfaces, and only retain the speed of one fan. Other fans can also achieve the purpose of temperature control and speed regulation.
