Computers do not require high temperature and humidity, so long as users feel comfortable in the environment, the computer can adapt. Temperature – 0 C – 50 C relative humidity – 30% – 70% temperature is too low, some parts may not work properly, this is not a computer fault; temperature is too high, computer heat dissipation is difficult, components will be misoperated due to overheating; relative temperature varies according to geographical location, too dry air may lead to static accumulation, damage integrated circuits, harmful to people and machines. Too humid air will cause oxidative rust on the chip inside the computer, resulting in bad contactor or short circuit.
