i have a Rosewill 120mm case fan which has 3 pin connector and a molex 4 pin. when i plug the 3 pin connector to my motherboard sys_fan2, the fan does not work. and the 4 pin molex can not connect to my molex cables from psu cuz the header are same. so what should i do???

Connect the 4 pin molex to the 4 pin molex connector of the PSU.
Thank you for B.a. man, No, I am a bit confused on that one myself, the only thing I can think is that the wire is somehow damaged, or that your mobo's fan header is not working properly, do you have another 3pin fan to test the header? Moto
