### 2. Core Design Components
The "pushPIN™" system used in this part consists of three main electronic/mechanical elements:
* **Heat Sink Body:** The 25x25mm aluminum block features vertical fins that increase surface area, allowing heat to transfer from the component to the surrounding air.
* **Push-Pins:** These are precision-molded nylon or brass pins that pass through pre-drilled holes in the Printed Circuit Board (PCB). They provide the necessary downward force to ensure high thermal contact.
* **Compression Springs:** These sit on the push-pins to provide a specific, consistent pressure (preload) between the heat sink and the electronic chip, preventing gaps that cause overheating.

### 4. Thermal Interface Material (TIM)
The part suffix "**C3**" indicates that it typically comes with a pre-applied high-performance **Thermal Interface Material**. This is a conductive pad or grease located on the base of the heat sink that fills microscopic air gaps between the heat sink and the CPU/GPU, significantly improving heat transfer efficiency.
