Securing the Heatsink Clip

The heatsink clip is made of spring steel and its tension holds the heatsink firmly against the CPU (see Figure 34).


Figure 34: Heatsink Clip

Looking through the fins of the heatsink, we see that the clip isn’t symmetrical. The point of the clip will push down on the CPU die when properly installed.

 


Use a flat-head screwdriver or “other appropriate tool” to secure the clip to the other side of the CPU socket. Place the screwdriver into the clip opening for it and gently push down and slightly away from the CPU socket, allowing the clip to clear the three notches of the CPU socket. Then, push the clip back toward the socket, engaging the three notches (see Figure 35 and Figure 36).


Figure 35: Securing the heatsink

Be gentle and avoid putting unnecessary force on the clip and the CPU socket.

 



Figure 36: Engaging the clip of the heatsink.

This “appropriate tool” (flat-head screwdriver) allows you to push the clip down and lock it into place. The other end of the clip is already engaged to the notches of the CPU socket on the other side of the heatsink. Be sure to select a tool that won’t slip and damage the mainboard. Do not push down on the heatsink itself. The clip will push the heatsink down naturally and allow it to contact the die of the CPU.

 


If you read the AMD instructions for installing the Athlon, they say to use the “appropriate tool” to secure the clip, but they give absolutely no clue as to what that tool is. Pliers? Hammer? Power Drill? Weed Eater?

The heatsink here seems to have a natural affinity for a flat-head screwdriver, and that tool works well here, so it’s the one we’ll use. Be careful so that the tool doesn’t slip and damage the mainboard. Don’t use an “inappropriate” tool which you think might slip.

The AMD heatsink puts considerable force on the notches that the heatsink locks into. Because of this, be gentle when using the screwdriver to push down and lock in the heatsink. Don’t push the lever much farther down than necessary to secure the heatsink.
