h105 Fan headers

[Swi1ch]

I'm halfway through building my rig, and i'm not sure which headers to use for installing the h105. I don't have a 3-pin to molex for the pump so i'll have to use the mobo headers for now.

Some people seem to recommend having the pump on the cpu_fan header, and the fans on any other available 4-pin header, whereas Corsair's official video recommends having the fans on the cpu_fan and the pump anywhere else.

Follow Corsair's official advice. Use CPU_FAN for PWM fans and use CPU_FAN2 (if there is one) or a SYS_FAN for pump. It's what I did when I fitted a H105 and no issues.

Vice versa might also be okay depending on the SYS_FAN header and whether it can do PWM. Less trouble to just do it the other way, really.
