asus z170-e fan header question

[hwlr77]

my motherboard is asus z170-e, and my case is a corsair spec 2

i have two exhaust fans connected to chassis fan 1. 2 intake fans connected to chassis 2. and i'd like to setup an h75 for my cpu, but not sure about the headers. i have cpu fan, cpu op, and w pump left to work with..

i've heard the pump should be connected to the cpu header, can the radiator fans connect to one of the others? best to disable those fans in the bios, so their at max power all the time?

the manual for the h75 is pretty minimal :/

I'd connect your setup like this:

CPU_FAN ---> 2x Radiator Fans of the Corsair H75 via included Y-cable
CPU_OPT ---> None
CHA_FAN1 --> 2x Exhaust Fans
CHA_FAN2 --> 2x Intake Fans
W_PUMP ---> Corsair H75 Pump 3-pin

The W_PUMP+ headers of the Asus Mobos are usually default at Full Speed (though it can be changed in BIOS). The AIO pump is recommended to be connected here to supply constant water flow as your pump is non-variable.

Corsair recommends connecting the pump on a non-CPU fan header (since you don't want to change the pump's speed).

The setup above would ensure that pump is 100% full speed, while its 2x fans would change speed depending on the CPU load/heat.

The other fans connected to the CHA_FAN headers, it's a matter of preference whether you want to change its speed or not.
