Corsair H100i v2 - fan header confusion

I'm currently mid-build on a new system and have some confusion over fan headers

I'm running a Corsair H100i v2 - which fan header on Gigabyte GA-AX370 mobo?
CPU is AMD Ryzen if it makes any difference

Do I use CPU_Fan, CPU_OPT or SYS_Pump?

Thanks in advance
PS - Corsair advised me to ask Gigabyte. Gigabyte haven't got back to me yet
