Hi, i have a corsair h55 liquid cpu cooler and an asus z170 pro gaming motherboard. I was wondering where on the motherboard is it safe to plug the 3 pin pump power connector, should i plug it in the cpu_fan or in the cpu_opt?

thanks in advance!

thank you for the response, may i ask why this is the case? (just for future reference)

also, would i be able to plug another fan into the cpu_opt socket?

You want the pump to always receive a constant voltage. Since the cpu fan header is based on the cpu temperature and will fluctuate, it's not ideal to use the cpu fan header to power the water pump.
Yes you can put another fan on the cpu_opt socket, it will match the same profile with the cpu fan header.
