Abstract
The invention provides a method for controlling computer temperature and a computer. The method comprises the following steps: temperature in the computer is detected in real time to obtain a current temperature; and the current temperature is compared with a preset first threshold value. If the current temperature is higher than the first threshold value, the computer is started or operated in a conventional mode; and if the current temperature is lower than the first threshold value, a fan in the computer is controlled to rotate reversely or stop rotating. The method fully utilizes heat generated by the computer to change environmental temperature and needs no additional heating component and power supply circuit; therefore, the method is easily realized, has good suitability and can be applied widely. By controlling the fan to rotate reversely, the method can increase the small environment temperature of the entire system, thus leading the system to stay under reliable working environment temperature. The method is simply controlled and has low cost.
