At present, can come to dispel the heat by the installation system fan usually in the computer for computer system, and the rotating speed of fan is normally controlled through rotation speed of the fan control curve (Fan Speed Control Curve).
Please, be painted with two rotation speed of the fan control curve A and B among the figure, under same temperature with reference to Fig. 1; The corresponding rotation speed of the fan of curve A is greater than the corresponding rotation speed of the fan of curve B (dutycycle % is meant the operation cycle of the pulse-width signal that is used to control rotation speed of the fan among the figure, is 80% like 80 expression dutycycles), that is to say that curve A is used for high-power hardware is dispelled the heat; And curve B is used for lower powered hardware is dispelled the heat; Effectively to utilize electric energy, above-mentioned two curves of brief account only here are during real work; Possibly also comprise more a plurality of different curves, with the different hardware of correspondence.Present fan rotary speed control system is through BIOS (Basic Input Output System; Basic input output system) module detects the hardware in the system earlier, comes corresponding selection rotation speed of the fan control curve according to hardware again, for example; When the SATA hard disk has been installed by system; The SATA hard disk has been installed by the BIOS module system of detecting, and then fan rotary speed control system trade-off curve A carries out rotating speed control to fan, when the SAS hard disk has been installed by system; The SAS hard disk has been installed by the BIOS module system of detecting, and then fan rotary speed control system trade-off curve B carries out rotating speed control to fan.
But sometimes; A kind of new hardware possibly installed by system; And the BIOS module can't judge which the pairing rotation speed of the fan control of this new hardware curve is, thus can only select the maximum rotation speed of the fan control curve (like curve A) of rotation speed of the fan to carry out the control of rotation speed of the fan, if this new hardware does not need so high rotation speed of the fan; Then wasted electric energy, and can make noise become big.
Summary of the invention
In view of foregoing, be necessary to provide a kind of fan rotary speed control system and method for saving electric energy.
A kind of fan rotary speed control system; Be used to control the rotating speed of a computer system fan; This fan rotary speed control system comprises a BIOS module, a fan and a hardware; This BIOS module comprises an initial voltage consumption detecting unit, a storage unit, a query unit and a control unit; The form of this cell stores one rotation speed of the fan control curve and hardware starting voltage consumption coupling, when carrying out the BIOS self-check program, this starting voltage consumes the starting voltage consumption that detecting unit is used to detect this hardware; The rotation speed of the fan control curve that the form that this query unit is used to inquire about this storage unit is complementary with the starting voltage consumption of finding out with this hardware, this control unit is used for the rotating speed according to this fan of the corresponding control of rotation speed of the fan control curve that inquires.
A kind of fan rotational frequency control method; Be used to control the rotating speed of a computer system fan; This computer system comprises a storage unit, the form of this cell stores one rotation speed of the fan control curve and hardware starting voltage consumption coupling, and this fan rotational frequency control method comprises:
