I think that it is Socket AM2, but like you said, I can't find info on the motherboard maker anywhere, even on Dell's website. Assuming that it is, how hard is it to swap out a processor?
I found this fan on Dell's website. Do you think this would work? Thanks for answering all these questions for me by the way.
