What is the optimal temperature range for operating equipment in a data centre?

The optimal temperature range for operating equipment in a data centre is 68-72°F. This range is widely recognized as it helps maintain a balance between equipment performance and reliability. At temperatures within this range, servers and other critical hardware can operate efficiently without overheating, which is crucial for preventing hardware failures and ensuring longevity.

Additionally, maintaining temperatures around 70°F allows for sufficient cooling while not requiring excessive energy use, contributing to energy efficiency in data centre operations. This optimal range is derived from recommendations by various organizations, including the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), which has established guidelines advocating for environmental conditions that are conducive to the reliable operation of IT equipment.

The other temperature ranges provided are either too low or too high, potentially leading to inefficiencies and increased risk of thermal events that can impair performance or damage equipment. Operating at excessively low temperatures might not utilize energy effectively, while higher temperatures can lead to overheating, increased cooling costs, and greater likelihood of equipment failure. Hence, the choice of 68-72°F recognizes both operational efficiency and equipment safety.
