Output System) chip. The cooling fan includes a cable and a control
chip. The control chip stores a manufacturer's name or a
manufacturer's code of the cooling fan. The BIOS chip stores a
plurality of manufacturers' names and/or manufacturers' codes and a
plurality of control curves. The BIOS chip reads the manufacturer's
name and/or the manufacturer's code stored in the control chip

Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a cooling system.
[0003] 2. Description of Related Art
[0004] Manufacturers usually have more than one supplier for the
same item. This minimizes downtime when one supplier runs out of
the item being supplied. However there is a downsize to this
strategy. When a manufacturer of servers have more than one cooling
fan supplier, the fans will, most of the time, have different
actual performance parameters due to differences in manufacturing
technique, skills etc. Such differences can be difficult for
designers of the servers to accommodate such as when they are
designing fan speed control curves.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] Many aspects of the embodiments can be better understood
with reference to the following drawings. The components in the
drawings are not necessarily drawn to scale, the emphasis instead
being placed upon clearly illustrating the principles of the
present embodiments. Moreover, in the drawings, like reference
numerals designate corresponding parts throughout the views.
[0006] FIG. 1 is a block diagram of an exemplary embodiment of a
cooling system, the cooling system including a control chip, a
cable, and a connector.
[0007] FIG. 2 is a block diagram of the control chip, the cable,
and the connector of FIG. 1.
DETAILED DESCRIPTION
[0008] The disclosure, including the accompanying drawings, is
illustrated by way of examples and not by way of limitation. It
should be noted that references to "an" or "one" embodiment in this
disclosure are not necessarily to the same embodiment, and such
references mean at least one.
[0009] Referring to FIG. 1, an exemplary embodiment of a cooling
system for a server includes a cooling fan 10 and a BIOS (Basic
Input Output System) chip 20 set on a motherboard 50.
[0010] The cooling fan 10 includes fan blades 100, a driver 110, a
control chip 120, a cable 150, and a connector 160. The control
chip 120 receives control signals from the BIOS chip 20 through the
cable 150 and the connector 160, and controls the driver 110
according to the control signals. The driver 110 drives the fan
blades 100. The control chip 120 further transmits working
parameters of the cooling fan 10 to the BIOS chip 20. The control
chip 120 stores a manufacturer's name and/or a manufacturer's code
of the cooling fan 10.
[0011] Referring to FIG. 2, the cable 150 includes a speed wire, a
power wire, a ground wire, a pulse wire, and an information wire.
The connector 160 includes first to fifth pins. The first pin is a
speed pin TACH. The second pin is a power pin +12V. The third pin
is a ground pin GND. The fourth pin is a pulse pin PWM. The fifth
pin is an information pin INFO. First terminals of the five wires
of the cable 150 are connected to the control chip 120. Second
terminals of the five wires of the cable 150 are respectively
connected to the five pins of the connector 160. The connector 160
connects to the motherboard 50. The speed wire transmits speed data
of the cooling fan 10 to the BIOS chip 20. The power wire and the
ground wire transmit power to the control chip 120. The pulse wire
transmits pulse width modulation signal to the control chip 120 for
controlling the cooling fan 10. The information wire transmits
information of the cooling fan 10, such as the manufacturer's name
and/or the manufacturer's code of the cooling fan 10, to the
control chip 120.
[0012] The BIOS chip 20 stores a plurality of different
manufacturers' names and/or manufacturers' codes, and a plurality
of control curves. Each manufacturer's name and/or manufacturer's
code corresponds to a control curve. For example, the
manufacturer's name of A corresponds to a first control curve, and
the manufacturer's name of B corresponds to a second control curve.
Each control curve includes a plurality of duty cycles and a
plurality of temperatures. Each duty cycle corresponds to a
temperature. For example, when the temperature is 50 degrees
Celsius, the duty cycle is 50%. When the temperature is 60 degrees
Celsius, the duty cycle is 60%.
[0013] When the cooling fan 10 is mounted in the server, the BIOS
chip 20 acquires the manufacturer's name and/or the manufacturer's
code of the cooling fan 10 stored in the control chip 120 through
the cable 150 and the connector 160. After that, the BIOS chip 20
obtains a control curve according to the manufacturer's name and/or
the manufacturer's code, and transmits the control curve to the
control chip 120. The control chip 120 controls the cooling fan 10
according to the control curve.
[0014] The foregoing description of the exemplary embodiments of
the disclosure has been presented only for the purposes of
illustration and description and is not intended to be exhaustive
or to limit the disclosure to the precise forms disclosed. Many
modifications and variations are possible in light of everything
above. The embodiments were chosen and described in order to
explain the principles of the disclosure and their practical
application so as to enable others of ordinary skill in the art to
utilize the disclosure and various embodiments and with various
modifications as are suited to the particular use contemplated.
Alternative embodiments will become apparent to those of ordinary
skills in the art to which the present disclosure pertains without
departing from its spirit and scope. Accordingly, the scope of the
present disclosure is defined by the appended claims rather than
the foregoing description and the exemplary embodiments described
therein.
