Just finished my build..... have a Corsair H75 and an Asus Z170 mobo.... the mobo has a water pump plug... which should I plug the pump/cpu portion of the H75 in to?
 
Solution
Cpu_opt is usually just a secondary cpu_fan header. Plug it in cpu_fan. The PC may not boot without that and you can control either with PWM.
