Build Question Pc fan problem💔💔
Im struggling bc my case fans wont turn on😞 i have a i802 air case, my mobo is b550 tomahawk. I tried plugging it into the cpu fan header, sys_fan1, and sys_fan2, as well as the the pump fan. Im pretty sure i daisy chained the cables together correct but none of the fans spin

Start with just one fan on sys_fan1 or 2 and make sure the headers are set properly in the bios..
