A cooling fin assembly according to the invention includes a plurality of cooling fins joined with one another for forming a plurality of vertical and parallel cooling fins mounted on a base of a heat sink. Wherein, two sides at a bottom portion of a main body of each cooling fin are provided with a clasp piece, respectively, a bottom edge of the main body is transversely extended and formed with a connecting piece, and an edge of the connecting piece is further formed with a positioning piece by folding upward. When a second cooling fin is butted against a side edge of the positioning piece of a second cooling fin, the clasp piece of the second cooling fin is clasped at the positioning piece of the first cooling fin, thereby fastening and joining the cooling fins to one another.
