Description
Technical field
The present invention relates to the computer technology field, particularly relate to a kind of mthods, systems and devices of adjusting rotating speed of radiating equipment in the data processing equipment.
Background technology
At present, universal day by day along with notebook computer, the becoming stronger day by day of function, notebook computer has obtained application more and more widely in people's life, brought into play increasing effect.The powerful develop rapidly that derives from notebook computer hardware of function, and these all are to come from the chip microminiaturization day by day and the high speed of travelling speed.And in this simultaneously, these have also inevitably caused the increase of hardware thermal value.For fear of notebook computer when in use, produce a series of problem because temperature is too high, present notebook computer has all been equipped powerful heat abstractor, from before the simple fan more and more higher fan of rotating speed finally, more and more till now water pump cooling systems that use all are that enormous function has been brought into play in the heat radiation of notebook computer.
When notebook computer was more and more popularized, people also had higher requirement to the comfortableness that notebook uses, and the noise problem of notebook computer is exactly a major criterion of comfortableness.The noise that notebook computer produces is excessive, will have a strong impact on user's use experience.Therefore, the user also is more and more to the concern of the noiseproof feature of notebook computer, wishes that notebook computer can be when in use, more peace and quiet.
