The part number **ATS-07B-149-C2-R0** refers to a high-performance **heat sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "blue ICE" push-pin series designed for cooling electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 35mm x 35mm x 20mm | | **Fin Type** | Straight Fin | | **Attachment Method** | Push-Pin (Brass/Plastic) | | **Thermal Resistance** | 6.21°C/W (at 200 LFM) | | **Thermal Interface (TIM)** | T766 (Pre-applied thermal tape/grease) | --- ### 2. Design and Components The ATS-07B-149-C2-R0 is engineered for efficient heat dissipation through several key mechanical and chemical features: #### A. Fin Geometry The heat sink uses a **straight-fin** configuration. This design is optimized for environments with forced air cooling (fans). The spacing between the fins allows air to pass through with minimal pressure drop, maximizing surface area contact. #### B. Attachment Mechanism (Push-Pins) Unlike adhesive-only heat sinks, this model uses **Push-Pins** with compression springs: * **Stability:** Provides a precise, uniform pressure across the component surface. * **Reliability:** Ensures the heat sink does not detach during mechanical shock or vibration. * **Hole Pattern:** Requires pre-drilled holes in the PCB at a 30mm pitch (distance between holes). #### C. Thermal Interface Material (TIM) The **"C2"** in the part number indicates the specific thermal interface material. It comes with **T766** pre-applied. This material fills the microscopic air gaps between the chip and the heat sink base to improve thermal conductivity. --- ### 3. Thermal Performance Profile Thermal resistance varies based on the airflow (measured in Linear Feet per Minute - LFM): | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (Natural/Low)** | 8.00 | | **200 (Standard)** | 6.21 | | **400 (High)** | 4.80 | --- ### 4.
