Hello all, I need help to set up fans because I'm new with this. My motherboard is Biostar a780l3l and has a SYS_FAN1. Do I put one fan there? Do I need just one fan or more? My case has 3 spots to put fans on, 2 on the side and one from behind. Or do I put one fan in the motherboard and other 2 in the PSU? If I only need one fan do I put it in the motherboard or PSU? I'll upload my dxdiag just in case.
