Hello! It always says that the cpu fan has a problem, but the computer started correctly, one day i saw that one of the fans didnt work, i saw the connections, the cable which you connect the fans was destroyed, broken pins, and i cant connect it to it, so i connected the fans to the mobo where it says CPU_FAN and CPU_OPT, but the corsair pump led wont turn on and before the fans did a lot of noise, now it doesnt, what can i do?
