For a server room, you want to keep the temperature between 18°C and 25°C, which is about 64°F to 77°F. The ideal is usually around 20°C to 24°C, or 68°F to 75°F. Keeping the temperature in this range helps ensure your servers run smoothly without overheating. Regularly monitoring the temperature and having good climate control in place are key to maintaining a stable environment for your IT servers.
Server Room Temperature Monitoring
Server room temperature monitoring devices monitor the ambient temperature within your IT environment for analysis and can issue alerts when the temperature rises (or falls) below preset threshold alarm levels. If your server room temperature is too high, the room can be uncomfortable to work in and could lead to heat damage to batteries. Too cold and humidity levels could rise due to condensation build up as the air conditioned air hits higher temperature components within the room. Cooling is also expensive and monitoring temperatures can help to improve energy efficiency and reduce operational costs.
