Zalman CPU Fan on an old Athlon 1GHz CPU Posted on 29th July 2015 by enquire to annotate I replaced the fan of my old PC with this one. It runs more quiet than the old one. Recently, however, I found it with lots of dust. I need to clean it. Posted by ajdv on 2008-04-23 00:31:19 Tagged: , cpu fan , cpu , athlon
