The **ATS-04B-149-C2-R0** is a high-performance heat sink manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **blueICE™** series and is specifically designed for thermal management of electronic components like CPUs, GPUs, and high-density power modules. --- ## 1. Technical Specifications The following table outlines the physical and thermal properties of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions** | 35mm x 35mm x 20mm | | **Thermal Resistance** | 6.22°C/W (at 200 LFM) | | **Fin Type** | Straight Fin | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ## 2. Key Electronic Functions While the heat sink itself is a passive mechanical part, its electronic role is critical for the reliability of the system: ### A. Thermal Dissipation The primary function is to conduct heat away from a semiconductor junction. By increasing the surface area exposed to airflow, it prevents **Thermal Throttling** in processors and ensures the component stays within its Safe Operating Area (SOA). ### B. Thermal Interface Material (TIM) The "C2" suffix indicates that the part comes with **T766** thermal grease pre-applied. This material fills microscopic air gaps between the electronic chip and the aluminum base, significantly reducing thermal impedance. ### C. Attachment Mechanism (pushPIN™) The part uses a specialized mounting system that includes: * **Compression Springs:** These ensure consistent pressure across the electronic package, preventing "hot spots." * **Brass Components:** These provide a secure mechanical bond to the PCB through pre-drilled holes. --- ## 3.
