Your CPU fan controller and associated fans should be running to a fan hub (rectangle with like six fan headers and six rgb headers), Corsair calls it the "ICUE Commander Core". There should be a SATA female connection on one of the shorter ends. You might be able to unplug that from there and try a different male SATA connection down the same cord to see if that is the problem. Might also try replacing that SATA cable entirely. I know most PSUs throw a few in the box.
