So, put together a new build today, and at first power up, fans in BeQuiet cooler would not spin up. Case fans work fine, graphics card fans ran, all else appears good. Corsair 550W PSU, Asrock B450M Pro 4 mobo, Ryzen 5 3600 CPU, Corsair LPX 3200 RAM (2x 8GB). Power leads from fans on correct headers on mobo, all leads from PSU connected to mobo. The only thing I can think is either borked mobo or bad fans on cooler. Tomorrow I'll swap out the Dark Rock Pro for the stock cooler and see if it spins up; if not, what else could it be but the mobo? If you all have any ideas for me, please send them along. I'm about to tear it down and start over, but I'd rather not if I don't have to. TIA for any help you can lend.
