I´m getting a new cpu 4800+ x2(old 3500+) and i´m wondering if my fan (Zalman) will work with it,i opend my box up but cant see any serial number on the fan to indicate what type it is.I found three fans on Zalmans website that look like my fan,2 of wich dosent say they support dual cores only one does.Is there any way to find ought what type of fan i have?
