### 2. Physical Design & Construction
* **Heat Sink Material:** Manufactured from extruded aluminum. Aluminum is chosen for its lightweight properties and excellent thermal conductivity. The **Blue Anodized** finish provides better protection against corrosion and slightly increases emissivity.
* **Straight Fin Design:** The fins are aligned in a single direction. This design is optimized for environments with **forced convection** (air flowing from a fan in a specific direction).
* **Push-Pin Attachment:** Instead of using messy thermal adhesive or tape, this part uses plastic push-pins and metal springs. This ensures constant pressure on the chip, improving thermal transfer and allowing for easy removal/rework.

### 3. Thermal Performance Indicators
Thermal resistance is measured in °C/W (Degrees Celsius per Watt). Lower values represent better cooling efficiency.
| Airflow Velocity (LFM) | Thermal Resistance (°C/W) |
| :--- | :--- |
| 1.0 m/s (200 LFM) | 2.07 |
| 2.0 m/s (400 LFM) | 1.19 |
| 3.0 m/s (600 LFM) | 0.93 |
