The **ATS-12F-81-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or failure. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal properties. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum (Blue Anodized) | | **Dimensions (L x W x H)** | 30.00mm x 30.00mm x 20.00mm | | **Fin Style** | XCUT (Cross-cut) | | **Attachment Method** | Push-Pin (Spring-loaded) | | **Thermal Resistance** | 14.03°C/W (at 100 LFM) to 2.56°C/W (at 700 LFM) | --- ### 2. Key Design Features * **XCUT Fin Pattern:** The fins are designed with a cross-cut pattern. This allows for multi-directional airflow, making it highly effective in systems where the direction of the cooling fan's exhaust might vary or be turbulent. * **pushPIN™ Attachment:** Instead of messy adhesives, this part uses a mechanical push-pin system. This provides consistent pressure (interface force) between the heat sink and the chip, improving thermal transfer. * **Blue Anodized Finish:** The surface treatment is not just for aesthetics; anodization increases the surface area at a microscopic level and protects the aluminum from corrosion. * **Pre-Applied Thermal Interface Material (TIM):** This specific model typically comes with **T766** thermal grease pre-applied, ensuring immediate out-of-the-box installation. --- ### 3. Application Use Cases This component is typically found in: 1. **Networking Hardware:** Routers, switches, and modems. 2. **Embedded Systems:** Industrial PCs and Single Board Computers (SBCs). 3. **Power Supplies:** Cooling voltage regulators and MOSFETs. --- ### 4. Comparison of Airflow Performance Thermal resistance decreases as airflow (measured in Linear Feet per Minute - LFM) increases: | Airflow Speed (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 14.03 | | 300 (1.5 m/s) | 5.64 | | 500 (2.5 m/s) | 3.62 | | 700 (3.5 m/s) | 2.56 |
