Nvidia also released today the v6.00 BETA nForce System Tools, with ESA support. The software package includes the Nvidia control Panel and Nvidia System Monitor software utilities. Both bring control and reporting to the desktop. The latest BETA version adds support for Enthusiast System Architecture, or ESA for short. ESA is a new open industry standard for controlling and monitoring real time devices.
ESA is very similar to any another mechanism for the communication between devices. The difference is, ESA enables devices that do not have a mechanism for communication today suck as PC power supplies, chassis, and water cooling systems. More information is available here.
