H60 and two fans on Gigabyte Z170N-Wifi mini ITX board?

Hi, I have a Z170N-wifi mobo which I'm putting inside a Thermaltake Core V1, with a corsair H60 to cool the CPU.

This means I have three things that need connected to fan headers - the 20cm three pin case fan in the case, the three pin pump connector for the H60 and the four pin fan to attach to the radiator.

The motherboard has two four pin fan headers, CPU and System.
I'm getting a four-pin splitter to try running all three, but I'm wondering how to connect things.

I'm only a little confused as the pins are laid out differently for the CPU and System fan headers:
Cpu, from 1-4 is: GND, +12V, Sense, Speed Control
Sys, from 1-4 is: GND, Speed Control, Sense, VCC

I'm just wondering whether 3 pin fans will even work off the system header - is it not VCC which provides power for the fans to run?

My current thought is to power the Pump from the CPU header, as it is three pin will it just run at full power constantly? Then use a 4 pin splitter to run the two fans from the system fan header.

That or I don't use the 20cm fan. I'm using a reference RX480 which should exhaust hot air, and the layout for the other two fans would put one on each side of the radiator!

The instructions for the H60 suggest that it doesn't matter which header the pump is connected to...

Sorry it's a bit long and convoluted, but the last parts for the build (PSU, GPU, RAM) arrive tomorrow and I'd like to get started!
Thanks!

It will work any way you hook it up and the 3 pin fan has no speed control.
You could even buy a Molex adapter for one of the fans and run it off the power supply

Ok, thanks. I managed to find a 5-way PWM fan splitter today that will take power from a SATA power connector rather than molex or by horrendously overloading the motherboard, so with any luck that'll do the job nicely. I'll be able to stick two 80mm fans into the rear of it too to exhaust if that works as expected.

Just to double check, will the pin layout difference between the CPU and System fan headers make any difference at all with 3 pin connectors?

No they will work just the same just not speed controlled.
