The **ATS-18F-99-C1-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 high-power transistors. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Series** | pushPIN™ | | **Attachment Type** | Push-Pin | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 11.49°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 45.00mm x 45.00mm | | **Height (Off Base)** | 20.00mm | | **Thermal Interface Material (TIM)** | ATS-54 (Pre-applied) | --- ### 2. Key Design Features * **Fin Type (Cross-Cut):** The "99" in the part number indicates a specific fin pattern. Cross-cut patterns allow for multi-directional airflow, making the heat sink effective even in systems where the direction of the fan exhaust is inconsistent. * **pushPIN™ Mounting:** This part utilizes a specialized mounting system that uses a spring-loaded pin. This ensures consistent pressure between the heat sink and the component, optimizing thermal transfer. * **Blue Anodized Coating:** The blue finish is not just for aesthetics; anodizing protects the aluminum from corrosion and slightly improves surface emissivity for better radiant heat transfer. * **Pre-applied TIM:** It comes with **ATS-54**, a high-performance thermal interface material already applied to the base. This simplifies the assembly process and ensures a bubble-free thermal connection. --- ### 3. Thermal Performance (Airflow) Performance varies based on the Velocity of air (measured in Linear Feet per Minute - LFM): | Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 11.49 | | 300 (1.5 m/s) | 3.92 | | 500 (2.5 m/s) | 2.59 | | 700 (3.5 m/s) | 2.11 | --- ### 4.
