Hi, i have a this old computer system for over a decade now though it was just sitting there collecting dust in my store room for like past 5-6 years. Today i finally decided to take it apart to see what's inside it (it doesn't turn on). i have removed everything very carefully except I can't really figure out how to remove this old intel cooling fan, it is a Intel A80852-001 cooling fan. im sure im supposed to find some type of screws but i cant see any? can anyone help me with removing this old cooling fan?
