S102: and judging whether the fan in the on-position state is the pull-out state, if so, executing the step S103, and if not, not processing.
After the in-place state of each fan in the server fan set is detected, whether a fan in the in-place state is a pulled-out fan is judged, if yes, it is indicated that the fan is pulled out currently, in order to maintain the heat dissipation effect before the fan is pulled out, the rotation speed of each fan which is remained in the server fan set is generally defaulted to be rapidly increased, if the default rotation speed is rapidly increased to the maximum rotation speed, step S103 is executed, if not, it is indicated that each fan in the server fan set is in a normal insertion state, and no processing is needed.

When the fans with the in-place states being in the pulling-out states are determined to exist, the fans with the in-place states being in the pulling-out states are determined to be target fans, and the rotating speeds of the fans except the target fans in the server fan set are set to be first preset rotating speeds, so that the rotating speeds of the fans except the target fans in the server fan set are reduced, and the phenomenon that the rotating speeds of the remaining fans in the server fan set are rapidly increased and the fans are always kept rotating at high speeds due to the fact that the fans are pulled out is avoided.
S104: and when the existence of the fan insertion is detected, setting the rotating speed of the inserted fan to be a second preset rotating speed.
The second preset rotating speed is greater than the first preset rotating speed.
The rotational speed of the inserted fan is preset, and for example, in order to prevent the inserted fan from reversing to the maximum, the second preset rotational speed of the fan is set to the maximum rotational speed of the fan. The method comprises the steps of determining that a fan is pulled out from a server fan set, setting the rotating speeds of other fans except a target fan in the server fan set to be first preset rotating speeds, detecting whether a back-inserted fan exists, when the fact that the fan is inserted is detected, setting the rotating speed of the inserted fan to be second preset rotating speeds, and setting the second preset rotating speeds to be larger than the first preset rotating speeds, so that the rotating speed of the inserted fan is larger than the rotating speeds of the other fans except the inserted fan in the server fan set, the inserted fan is enabled to easily rotate along the same direction along with the other fans, and the probability of reverse rotation of the inserted fan is effectively reduced.
S105: and when the inserted fan delays for a first preset time length from the insertion, setting the rotating speed of each fan in the current server fan set to be in a preset automatic debugging mode.
The method comprises the steps of presetting the delay time length for restoring an automatic debugging mode of each fan inserted into a server fan set from the fan, and setting the rotating speed of each fan in the current server fan set to be in the preset automatic debugging mode when the inserted fan delays for the first preset time length from the insertion. Such as the first preset duration may be set to 20 seconds.
According to the technical scheme, when the situation that the fan is pulled out is detected, the rotating speeds of other fans except for the pulled target fan in the server fan set are set to be the first preset rotating speed, when the fan is inserted, the rotating speed of the inserted fan is set to be the second preset rotating speed, and the second preset rotating speed is larger than the first preset rotating speed, so that the rotating speed of the inserted fan is larger than the rotating speeds of other fans except for the inserted fan in the server fan set, the rotating speeds of other fans except for the pulled target fan in the server fan set are reduced, the reverse rotation probability of the inserted fan is effectively reduced, and the usability of the server system is improved.

And when determining that the fan is inserted from the pulling-out of the target fan to the time delay within the second preset time and the inserted fan is inserted from the inserting to the time delay within the first preset time, setting the rotating speed of each fan in the current server fan set to be in a preset automatic debugging mode. Therefore, after the inserted fans are successfully inserted, the fans are timely restored to the preset automatic debugging mode.

S209: the rotational speed of the plug-in fan is set to a second preset rotational speed, and the rotational speeds of the fans in the server fan set except the plug-in fan are set to a third preset rotational speed.
Wherein the third preset rotating speed is less than the first preset rotating speed.
And respectively presetting the wind speeds required to be adjusted by inserting the fans and other fans into the server fan set when the fans are inserted after the target fan is pulled out until the time delay exceeds a second preset time. If the wind speed of the inserted fan is set to be a second preset rotating speed, the second preset rotating speed is preset to be the maximum rotating speed of the fan.
