In some embodiments, the step of activating the fan to cool the hard disk includes:

In response to starting the fan for the first time, matching the rotational speed for the current hard disk temperature based on the corresponding relationship between the preset temperature and the rotational speed;

In response to the current hard disk temperature used in the last time not exceeding the current hard disk temperature collected in the previous time, the fan speed is adjusted based on a second preset rule, wherein the second preset rule is that the fan speed decreases for every preset degree decrease in temperature. preset number of revolutions.

In yet another embodiment, in order to facilitate the understanding of the technical solution of the present invention, the following takes the solid-state hard disk as an example. Control CPI achieves the purpose of reducing the temperature of the solid state drive by adjusting the fan speed. In addition, if the fan speed increases under extreme conditions, the temperature of the solid state drive is not significantly reduced in a short period of time, the main control CPU will start its internal cooling algorithm to achieve fast speed The purpose of reducing the temperature of the disk is to prevent the loss of user data or even the permanent damage of the solid-state hard disk caused by excessive temperature. This embodiment provides another hard disk cooling method, and the specific implementation is as follows:

First, set a temperature threshold a. When the temperature collected by the temperature sensor exceeds the threshold a, the main control CPU will start the fan, and the fan speed will increase by r for every n degree increase in the temperature collected by the temperature sensor. For every n degree decrease in temperature, the fan speed decreases by r revolutions. In addition, a maximum temperature threshold b is set. When the temperature of the disk collected by the temperature sensor exceeds b, the bandwidth limiting program is started to quickly reduce the temperature of the disk. The specific implementation steps are as follows:

Step 1, the temperature sensor periodically collects the disk temperature cur_temp and reports it to the main control CPU;

Step 2, the main control CPU determines whether the current temperature is greater than a, and if it is greater than a, starts the cooling fan, otherwise it does not start;

Step 3, the main control CPU adjusts the fan speed in real time through a preset mapping algorithm between the temperature and the speed;

Step 4, the main control CPU judges whether the current temperature is greater than b, and if it is greater than b, starts the cooling program, otherwise it does not start;

The specific algorithm for fan speed control is as follows:

If(cur_temp<a)

The main control CPU does not issue a startup command to the fan;

else if(cur_temp>=a&&cur_temp<b)

The main control CPU issues a startup command to the fan, and records old_temp=cur_temp;

If the temperature cur_temp received by the CPU next time is greater than old_temp, the fan speed will be increased. For every n degree increase in temperature, the fan speed will increase by r revolutions.

If the temperature cur_temp received by the CPU next time is less than old_temp, the fan speed will be reduced. For every n degree decrease in temperature, the fan speed will be reduced by r revolutions.

else if(cur_temp>=b)

Then, the bandwidth of the hard disk is limited by the bandwidth limiting algorithm, so as to achieve the purpose of reducing the temperature of the disk.

The algorithm for limiting hard disk bandwidth is as follows:

When the current temperature of the disk is greater than the set initial temperature threshold b, the main control CPU starts the bandwidth limiting program. If the current temperature cur_temp is greater than the initial temperature b, the IO bandwidth is reduced by limiting the concurrent number of IOs processed by the main control CPU. , every time the temperature increases by t degrees, the number of concurrent IOs decreases by num. On the contrary, when the temperature decreases by n degrees, the number of concurrent IOs increases by num. When the current temperature cur_temp received by the master CPU is less than the initial temperature b, the original IO is restored The number of concurrency to restore the original bandwidth.

In a method for cooling a hard disk in this embodiment, when the temperature of the solid state hard disk is too high, the temperature of the hard disk is quickly reduced by a combination of temperature control fans and bandwidth limitation, thereby preventing the solid state hard disk from running at high temperatures for a long time and avoiding data loss , or even permanently damaged solid-state drives.
