I’ve recently ended building a new pc, but all the fans are not working, they don’t spin and don’t light up. Pc seems to work fine, but i still didn’t do any benchmark because of the fans not working. Fans are all deepcool fc120 10 in total and are all connected to a deepcool sc790 argb/pwm hub, 3 series of 3 daisychained and 1 alone. I connected the hub to the mobo (aorus b650 elite ax) like the instructions says, pwm pin in cpu_fan rgb pin in 5v rgb. Everything seems well connected, still no sign of life from the fans and of course they are not recognised in the bios. Aio pump works tho, so i tried to connect the pump to cpu_fan, and it works and pops up in the bios. I then try to connect pwm from the hub in sys_fan1 but it didn’t work. Does anyone knows how to fix this issues? To me sounds like the hub is faulty, but maybe i’ve done something wrong that i didn’t noticed, i don’t know.
My guess is that you’re simply putting too much load onto the hub, with you connecting 10 fans on it when it only has the 3 PWM headers.
