The **ATS-12D-77-C2-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "pushPIN™" series, designed for cooling electronic components such as CPUs, GPUs, or high-power semiconductors. --- ### 1. Technical Specifications Below is a breakdown of the physical and thermal characteristics: | Property | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25mm x 25mm x 20mm | | **Thermal Resistance** | 9.30°C/W (Unducted Flow @ 100 LFM) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Interface (TIM)** | T766 (High Performance) | --- ### 2. Key Components & Features #### A. Fin Geometry (Super Fine Pitch) The "77" in the part number indicates the fin configuration. This model uses a **dense fin array** designed to maximize surface area for heat dissipation within a small footprint (25x25mm). #### B. PushPIN™ Attachment System Instead of using adhesive tape or standard screws, this part uses a spring-loaded push-pin system. * **Benefits:** Ensures constant pressure on the component, improving thermal transfer. * **Reliability:** Prevents the heat sink from shifting due to vibration or thermal expansion. #### C. Thermal Interface Material (TIM) The unit comes pre-applied with **T766 phase-change material**. This eliminates the need for manual thermal paste application and ensures a bubble-free contact between the component and the heat sink. --- ### 3. Thermal Performance Analysis Thermal resistance measures how effectively the part moves heat away from the silicon. Lower numbers are better. | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 9.30 | | 300 (1.5 m/s) | 5.21 | | 500 (2.5 m/s) | 4.17 | | 700 (3.5 m/s) | 3.59 | --- ### 4.
