Rotating speed is configured.
Optionally, a kind of possible stepping rotating speed can be more than or equal to the 1% of the maximum speed of fan.Such as fan is
High rotating speed is 2000 revs/min, then stepping rotating speed could be arranged to 20 revs/min, or it can also be provided that 25 revs/min.Because
Electronic equipment operationally, is usually and does not allow fan speed to decline, in case electronic equipment increases causing trouble because of thermic load,
Therefore, can be toward to a high-profile when the rotating speed that adjustment fan is current.
Optionally, adjust system fan or the current rotating speed of hard disk fan, can have different adjustment modes, divide below
It is not introduced.
In a kind of possible embodiment, the rotating speed of system fan can be adjusted by stepping rotating speed.Optionally, right
For system fan, stepping rotating speed during adjustment can be more than or equal to the 1% of system fan maximum speed, such as system fan
Maximum speed be 3000 revs/min, then stepping rotating speed could be arranged to 30 revs/min, or it can also be provided that 120 revs/min,
Etc..Stepping rotating speed can pre-set, or can also when adjusting the rotating speed of system fan according to system fan
The sensitive frequency of the hard disk in high rotating speed and/or electronic equipment is arranged, and illustrates separately below.
Pre-set the situation of stepping rotating speed.Such as, electronic equipment includes three hard disks, and the model of these three hard disk is respectively
Being 1,2 and 3, electronic equipment also includes a system fan, can be these three Hard disk heat radiation.Such as model is the hard disk of 1
The frequency that sensitive frequency includes is 10Hz, and the frequency band included is [20-30] Hz, and model is that the sensitive frequency of the hard disk of 2 includes
Frequency be 12Hz, model be the frequency band that the sensitive frequency of the hard disk of 3 includes be [40-50] Hz, the maximum speed of system fan
For example, 3000 revs/min.If the current rotating speed of system fan obtained is 600 revs/min, then the vibration that system fan is current
Frequency is 10Hz, and consistent with the sensitive frequency 10Hz of the hard disk that model is 1, such as stepping rotating speed is set in advance, for example,
30 revs/min, according to the rotating speed that stepping adjustment of rotational speed system fan is current, can be such as system by the adjustment of rotational speed of system fan
The current rotating speed of fan and stepping rotating speed sum, then after adjustment, the rotating speed of system fan is 630 revs/min, corresponding frequency is
10.5Hz, the most inconsistent with the sensitive frequency of the sensitive frequency of the hard disk that model is 1 and hard disk that model is 2, then can be true
Fixed this has adjusted, and system fan can be according to the rotary speed working after adjusting.And the stepping rotating speed such as preset be 120 turns/
Point, then it is the current rotating speed of system fan and stepping rotating speed sum by the adjustment of rotational speed of system fan, system fan after adjustment
Rotating speed be 720 revs/min, corresponding frequency is 12Hz, consistent with the sensitive frequency of the hard disk that model is 2, then need to continue
Adjusting the current rotating speed of system fan, can continue the adjustment of rotational speed of system fan is the current rotating speed of system fan and stepping
Rotating speed sum, is i.e. adjusted to 840 revs/min, judge the most again the frequency of vibration of system fan whether with the sensitivity of these hard disks
Frequency is consistent, to avoid the sensitive frequency of all hard disks as far as possible.Optionally, if the sensitive frequency of system fan and electronic equipment
In any one sensitive frequency of any one hard disk of need protection consistent, be considered as frequency of vibration and the hard disk of system fan
Sensitive frequency consistent, it is necessary to adjust system fan rotating speed.
When pre-setting stepping rotating speed, the size that stepping rotating speed is arranged and hard disk itself have relation.If hard disk is quick
Sense frequency ratio is more close, then the stepping rotating speed of setting can be larger, to avoid on the premise of reducing adjustment number of times as far as possible
All sensitive frequency.Such as, the frequency that the sensitive frequency at the hard disk that model is 1 includes is 10Hz, and the frequency band included is
[10.5-11] Hz, model be the frequency that the sensitive frequency of the hard disk of 2 includes be 11.5Hz, model is the sensitive frequency of the hard disk of 2
Including frequency band be [12-13] Hz in the case of, when system fan and hard disk fan maximum speed are 3000 revs/min, right
Arranging of stepping rotating speed can be different.
The hard disk in maximum speed according to system fan and/or electronic equipment when the rotating speed of system fan need to be adjusted
Sensitive frequency arranges the situation of stepping rotating speed.Such as, electronic equipment includes three hard disks, and the model of these three hard disk is respectively
1,2 and 3, electronic equipment also includes a system fan, can be these three Hard disk heat radiation.Such as model is the quick of the hard disk of 1
The frequency that sense frequency includes is 10Hz, and the frequency band included is [20-30] Hz, and model is that the sensitive frequency of the hard disk of 2 includes
Frequency is 12Hz, model be the frequency band that the sensitive frequency of the hard disk of 3 includes be [40-50] Hz, the maximum speed example of system fan
As for 3000 revs/min.Such as, the rotating speed that the system fan of acquisition is current is 600 revs/min, then the vibration that system fan is current
Frequency is 10Hz, consistent with the sensitive frequency 10Hz of the hard disk that model is 1, adjusts the current rotating speed of system fan to reduce
Number of times, can arrange stepping rotating speed according to the sensitive frequency of the hard disk in the maximum speed of system fan and/or electronic equipment,
The rotating speed making the system fan after adjusting can avoid 12Hz, [20-30] Hz and these sensitive frequency of [40-50] Hz simultaneously,
Such as stepping rotating speed can be set to 300 revs/min, then after adjustment, the rotating speed of system fan is 900 revs/min, corresponding frequency
Rate is 15Hz, the most inconsistent with the sensitive frequency of 3 hard disks, then to may determine that this has adjusted, and system fan can be by
According to the rotary speed working after adjusting, so, required adjustment number of times is less, and can avoid the sensitive frequency of all hard disks.
Optionally, adjust the rotating speed that hard disk fan is current, can be there to be different adjustment modes, for example, it is possible to pass through to preset
Stepping adjustment of rotational speed, it is also possible to when the rotating speed of fan need to be adjusted in maximum speed according to fan and/or electronic equipment
The sensitive frequency of hard disk arranges stepping rotating speed and is adjusted, and adjustment mode refers to the situation of system fan, repeats no more.
Certainly, it is more than example, the quantity of the hard disk that electronic equipment is included and sensitive frequency, and include
The quantity etc. of system fan, the embodiment of the present invention is not restricted.
Optionally, either system fan or hard disk fan, if the current frequency of vibration of fan obtained and sensitive frequency
Rate is inconsistent, then can make the rotating speed that fan holding is current.When the frequency of vibration that fan is current is inconsistent with sensitive frequency, firmly
Dish will not produce resonance, and vibratory output is less, therefore without adjusting the rotating speed of fan, makes the rotating speed that fan holding is current.
