Phanteks PWM Fan Hub
Phanteks PWM fan hub has six fan headers allowing for up to 12* fans (through Y-cable splitter) or 30 watts of consumed power. The package also includes 2 3-pin splitters for a total of 8 connections without needing to purchase additional splitters. The Phanteks logo can be illuminated when the fan hub is powered on. Mounting can be done on any Enthoo Series case with the provided screws or any other case using the universal velcro mounting strips.
* For PWM control, a total of 11 fans are supported. A motherboard CPU fan connector can only read one RPM signal. Therefore, the motherboard will only read the RPM signal from one device connected to Fan 1. The RPM for all other devices will be regulated according to FAN 1. Y-splitter should not be connected to FAN 1.
The PWM hub functions optimally when modulated by a PWM signal from the motherboard, which will allow the greatest control range. However, not all 4-pin motherboard connectors implement the PWM signal modulation.
Connecting the 4-pin to CPU_FAN
For full PWM functionality, Phanteks’ PWM hub requires users to connect the 4-pin connector to the “CPU_Fan” connector of the motherboard, because all motherboard manufacturers implements a PWM signal modulation on this connector. Connect the SATA 12V power to power the PWM hub. Not all motherboards have their CPU_Fan connector set on PWM signal modulation by default. Please consult your motherboard documentation for this matter.
Connecting the 4-pin to other 4-pin header (besides the CPU_Fan)
Other 4-pin connectors can be found on modern motherboards besides the “CPU_Fan” connector (e.g. “CPU_ Fan2”, “CHA_Fan”, “OPT_Fan”), however not all motherboard manufacturers implement a true PWM signal modulation onto these connectors. These type of 4-pin connectors modulate the RPM by voltage, which has a smaller control range compared to modulation by true PWM signal.
The 12V SATA power cable can not be used to power the PWM hub if connecting to these types of 4-pin connectors, due to the interference with the RPM regulation by voltage (resulting in the fans running on full RPM). The PWM hub will draw its power from the 4-pin connector, which is limited to a total device consuming 30W in total.
