### 3. Key Features
* **pushPIN™ Attachment:** This part uses a specialized attachment system consisting of a brass or plastic pin and a stainless steel spring. This ensures a consistent pressure (Force) against the component for optimal heat transfer.
* **Pre-Applied Thermal Interface Material (TIM):** Most "R0" variants come with a pre-applied thermal pad or phase-change material on the base, simplifying assembly.
* **Vertical Fin Design:** The straight-fin design is optimized for airflow environments, allowing air to pass through the gaps and carry heat away from the base.
