Abstract

The invention discloses a method for adjusting the rotating speed of a fan and an electronic device. The method and the electronic device are used for solving the technical problem that the performance of a hard disk is reduced due to the too large quantity of vibration transmitted by the fan to the hard disk. The method includes the steps that the current vibration frequency of the fan in the electronic device is obtained; whether the current vibration frequency is consistent with the sensitive frequency of the hard disk in the electronic device or not is judged; the sensitive frequency of the hard disk is the frequency for the hard disk to generate resonance; and if the current vibration frequency is consistent with the sensitive frequency, the rotating speed of the fan is adjusted, and the vibration frequency of the fan is not consistent with the sensitive frequency after adjustment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for adjusting the rotating speed of a fan and electronic equipment. Background technique [0002] At present, most electronic devices are equipped with cooling fans, and most of the electronic devices with increasing power consumption in use use high-speed fans to enhance the cooling effect. [0003] Generally, the electronic equipment is equipped with a hard disk, and the fan may be connected to the hard disk, so when the electronic equipment is running, the vibration generated by the fan rotation will be transmitted to the hard disk. For example, when the fan rotates at a high speed, the amount of vibration generated is relatively high, and excessive vibration will reduce the read and write accuracy of the hard disk, thereby affecting the read and write speed of the hard disk, resulting in a decline in the performance of the hard disk. In severe cases, it may cause...
