the stock rear 120mm fan appears to have two power cables.
the first is a 3pin, which doesnt seem to work when i connect it to the motherboard at the CHA_FAN or PWR_FAN, which i tested both and they both work.
the second is the common 4 prong power connector, male and female ends.
whats the purpose of having the 3 pin?
just to give users flexibility?
and does mine just not work?
i would just rather use the 3 pin to power it from the motherboard instead of having a power supply cable run all the way down to it.
