On this page you will find the standards recommended by ASHRAE for monitoring the environment in your data center or server room. With the proper placement, you'll receive notifications whenever there's a significant increase or decrease that might affect equipment efficiency. These sensors monitor. Every -17. 2 °C increase for the average CPU. When, exactly, does this become a problem? It varies by the equipment, but most CPUs are at risk. Data center managers can benefit from real-time information on the hot, chilly, or humid space by installing temperature sensors in key spots around the server room.
