Ps5 fan PWM trace broken to the southbridge chip

PS5 disc drive

Hi, I was wondering where abouts on the southbridge chip the fan connects to so I can jump a wire. The fan has power however isn’t spinning due to no PWM signal. I was wondering where abouts it would connect to on the southbridge chip or if I can connect it to get a PWM signal elsewhere?
