Okay so I'm looking at my motherboard (GIGABYTE H170-Gaming 3 Motherboard) and it only has 3 system header fans, 1 CPU fan, and the CPU_OPT that is meant for water cooling and such. My case (NZXT S340) has 4 fans that I want to use but the motherboard only has 3 system fan headers and I don't want to buy a splitter. Is it fine if I put 1 out of 4 of the case fans into the CPU_OPT?
