Only if fan has its own controller (like Zalman) Motherboard socket allows mobo to control speed. What motherboard? Very unusual to only have CPU header!mike some one told me if i connect the fan to 4 pin molex connecter from psu i should be able to controle the fan speed. i am confused, my case have 5 fan should i plug those fan into my mobo?i dont see anymore fan connecter in my mobo then cpu fan connecter.

The northbridge fan just like it says a northbridge fan. Your mobo probably has a passive heatsink there anyway but retained the fan header. Unless you want to put a 40mm 10K rpm fan on it, you should be ok. Or just route another case fan there.what is hell is north bridge fan header? it says on the manual connect the north bridge fan cable to this header.
