Case Fans

[woody30]

I have some BeQuiet 120mm fans coming in for my system and the case I have is a fractal design meshify c and the motherboard I have is an asus b550 f gaming wifi motherboard. The motherboard has connections labeled CPU_OPT, Fan 1, Fan 2, and Fan 3. Was wondering if there was a certain order I should plug these fan into or not for example like plugging top front fan into cpu_opt or should that go to fan 1? thanks for any input.

These labels don't mean anything other than to tell you what they correspond to in your BIOS/Mobo software. Other than making sure that the CPU cooler is on the CPU_FAN header, because the BIOS ties that more directly to CPU temps, plug in wherever is easiest. CPU_OPT means optional CPU fan, if you have something that needs more than one header. I use the CPU_OPT header for an exhaust fan on the top rear of my PC, and use the splitter for the two fans on my D15. I'd populate the case fans on the Fan 1, Fan 2, etc. headers first, and use the CPU_OPT last, just because the BIOS may treat it slightly differently by default, but that can easily be overridden.

CPU_OPT is synced with the CPU fan header as far as I know. The rest are independant, just choose the most convenient ones. OPT is primarily if you have two fans on your CPU HSF but can ofc be used for other fans as well if you wish.

the cpu fan header normly has more amps too thow we dont put hi power fans on coolers any more.... back in the day you need the amps for the brutfore for cooling as we didnt have tower coolers. any one remeber the tt volcano 8....
