I know there are a lot threads about this topic but my MoBo is a bit outdated so I need a clear answer. So I'm planning to buy a new case - Phanteks Enthoo Pro. Now here is my MoBo:
As you can see I have only one cpu_fan and only one extra header, the cha_fan 1. I read that the 4 pin cable coming from the fan hub is supposed to attach to the cpu_fan, but I need my cpu cooler on that one. Can I connect the 4 pin cable into the cha_fan 1 (3 pin header) then? Or is there a better way for all this?
