A fixing frame is used to fix at least one heat sink fan on a case of an electronic device. The fixing frame includes a cradle and at least one fastener. The cradle has two oppositely disposed plates, and the two plates respectively have a combining portion and a latching portion, such that at least one accommodation region is partitioned from the cradle for accommodating the fan, and the latching portion and the combining portion are combined with each other to form a clamping region. The fastener is disposed on the case and clamped in the clamping region, such that the cradle is fixed on the case.
