I try desperately find the 'part number' of the fan ‘connector’ cable, the male soldered on PCB is oK but the one on the cable is broken.

The fan is working, I just plug the pins in the order they came on the cable and sees it’s fine.

I don’t want to replace the original fan.

By the way the PCB Hard drive connector is not present but the Software says the Hard drive has problem.

So if somebody knows the part number of this one too, it would be very appreciated.
