All the parts needed to fit the cooling head to the motherboard. At the bottom left you can see the anti-condensation heater on the back of the CPU socket. To the right of that is the bracket for attaching the cooling head to the CPU, and at the top, the frame, thermal grease, screws and masking pads for CPUs without heat spreaders.
The same kit for Intel processors.
The Intel P4 version of the kit is on the left, and the AMD Athlon XP version is on the right.
