The Enthusiast System Architecture (ESA) is the industry’s first open-standard PC monitoring and control protocol for real-time communication and control of system thermal, electrical, acoustic and operating characteristics.

ESA-certified components and applications allow enthusiasts and power users to diagnose component-specific issues and tune their systems to meet their individual needs—whether it be reaching peak performance or modifying for a whisper-quiet home theater operation.

With ESA, PC and component manufacturers can deliver differentiated and value-added products, giving their customers unprecedented visibility and control over their systems and allowing them to achieve the highest possible performance.
