A heat sink retainer has a rectangle frame with four corners each having a slit defined through the corner. A pair of U shape clamping strips each has two legs. Each leg extends through a corresponding one of the slits. A controlling device pivotally connects to each of the clamping strips and has two driving bosses and each driving boss is integrally formed on a distal end of the controlling device and is clamped between the frame and the clamping strip to control movement of the distal ends of the clamping strip to engage/disengage with holes in the heat sink.
