Ideal Room Temperature for Computers

Even laptop computers are susceptible to high temperatures and humidity changes.

Computers are sensitive to temperature changes, as well as to changes in humidity. If the room temperature is too high, the components inside your computer can overheat and begin to fail. If the temperature and humidity are too low and then rise quickly, condensation can form on the components. Keeping your computer between certain temperature and humidity levels prevents system issues, such as failing components and data loss.

Temperature Level

The ideal room temperature for computers is between 60 and 75 degrees Fahrenheit. A room that is too cool is better than a room that is too warm. Temperatures above 75 degrees Fahrenheit can cause computer components to fail, even if a fan is present in the computer's case. If your home or business's temperature varies drastically, turn off your computer to keep it from overheating, especially during the summer months. During the winter months, if possible, close the vents in the or area containing your computer if you normally raise your thermostat to a temperature higher than 75 degrees Fahrenheit.

Humidity Level

Keep your home or business's humidity level between 35 and 40 percent to keep water droplets from forming on your computer and and inside of your computer's components. Keeping the humidity level low is key to avoiding problems such as the failure of circuits, chips and other components.


To monitor the temperature of the room or area containing your computer, use a thermometer that displays both temperature and humidity levels. Do not place the thermometer next to or near the computer because the device emits heat and the thermometer will register a higher reading. Place the thermometer away from the computer and other devices emitting heat.


When you are not using your computer, turn it off to reduce wear and tear on the system, as well as to reduce the amount of heat emitting from the device. Do not smoke around your computer. Smoke can clog your computer fan and other components. If the temperature in the room containing your computer falls to 32 degrees Fahrenheit or lower, turn off your computer and let the room heat to between 60 and 75 degrees Fahrenheit before turning it back on to keep condensation from forming on its components.
