### 2. Physical Design Features
* **Heat Sink Base:** A flat aluminum base designed for direct contact with the electronic component (often used with a Thermal Interface Material or TIM).
* **Fin Pattern:** This model utilizes a high-density fin structure to increase the surface area available for convective cooling.
* **Attachment Mechanism:** It uses a push-pin system with a compression spring. This ensures consistent pressure across the component, improving thermal transfer and preventing the heat sink from shifting during vibration.

### 3. Thermal Performance Profile
Thermal performance is measured in terms of **°C/W** (degrees Celsius per Watt), indicating how much the temperature rises per watt of power dissipated.
| Air Velocity (LFM) | 100 | 200 | 300 | 400 | 500 |
| :--- | :--- | :--- | :--- | :--- | :--- |
| **Resistance (Unducted)** | 4.97 | 2.85 | 2.27 | 1.97 | 1.76 |
| **Resistance (Ducted)** | 2.82 | 2.08 | 1.76 | 1.57 | 1.44 |
