The most widely adopted temperature range for a server room is 18-25°C. This ambient temperature range provides a comfortable environment for technicians and engineers to work in, and a suitable environment in which to run IT servers, networking devices and associated critical infrastructure including uninterruptible power supplies. Below 18°C and the room can become a little too cool and energy is wasted cooling the space. Above the temperature and the server room becomes a little too warm with the potential for humidity related problems. Whilst this is an overall suitable server room temperature range, it is important to identify ‘hot-spots’ i.e. warmer temperatures within the room and server racks which could potentially lead to heat-related problems.
