Abstract
The invention relates to a computer control field, and specifically provides a computer temperature-controlled and noise-reduced method. The invention integrates a host computer system thermal design and a power supply thermal design, and finds the optimal heat balance point, accordingly the rotate of fan is controlled and the noise of system is reduced. The rotate speed of radiator fan in a computer hardware is reasonably adjusted via a radiator test under the less load of system, on one hand the radiator requirement of each hardware can be satisfied, on the other hand the noise of system is reduced. The noise of system can be effectively reduced, using the inventive computer temperature-controlled and noise-reduced method, while the energy consumption is also reduced for providing direct economic benefit for user.
