SPEEDFAN realizes automatic control setting method for CPU fan

speed

First, the fan speed function of main board and fan interface

on the main board are given. Main board of the fan speed control

functions are divided into two PWM mode and DC mode, different

brand with different patterns, different types of motherboard

can also support two modes, specific support which model have

to go to the motherboard BIOS to see inside.

The so-called PWM mode, which refers to the fan's speed

adjustment, needs to be realized through a speed regulating

signal line, which is the 4pin interface (the 4pin interface

and the d-type of the outlet of the power supply) fan. Generally

speaking, 4pin fan is difficult to buy in the market, it often

only matches on the original radiator. However, we are more

common with the 3pin fan, which is inserted in the 3pin outlet

of the motherboard. Only the main board that supports the DC

speed control mode can control the 3pin fan. However, most

motherboards use PWM mode to speed the CPU fan. The premise of

using SPEEDFAN to automatically adjust the CPU fan speed is that

the motherboard supports either of the above two modes.

Although most of the motherboard has automatic adjustment

function to the CPU fan, however the mainboard comes often

disappointing, the features of the speed regulation such as

still think the noise is very big, or hope to be able to open

the fan when playing games, don't play games closed when the

fan, etc. SPEEDFAN is then used to personalize the CPU fans.

As for the use of SPEEDFAN to control the fan in the main board

BIOS, I am not sure, but I am closed anyway.

The SPEEDFAN software I used is in English version 4.38. The

latest version is version 4.40, but 4.40 is a little bit of a

problem on my computer, which is not as good as version 4.38,

so I'll take the 4.38 version. SPEENFAN is a very unique

software, it implements the function is very comprehensive, but

it is too detailed Settings (some not enough human nature), so

that a lot of friends think that this software are ineffective,

actually there is no set reason. Some difficult English friends

can also download the Chinese version. Since version 4.38,

SPEEDFAN has started to support the win732 and 64-bit operating

systems.

Run speedfan, and after a while, the interface appears:

Click "configure" to enter the options menu. I use the peeling

onion method to be set by shallow and deep, so that I can

remember easily and ask my friends to be patient. J

The first TAB can select which temperatures to display on the

display screen of the software. I chose to display TEMP1

(mainboard temperature), TEMP2 (CPU temperature) and HD0 (the

first hard disk temperature). Notice the plus sign on the left

side of the temperature marker? We're going to look at this plus

Note: TEMP1, The temperature of the representative is

different, and the friends have to decide for themselves which

of their SPEEDFAN is the main plate temperature and which is

the CPU temperature. If there is a mistake, the CPU temperature

will be white.

The second TAB allows you to select which fan speeds are

displayed on the software interface.

There are no other functions (there are five fans here because

the motherboard chip can support the control of five fans at

most, but the motherboard only gives you two fan interfaces).

Here I chose to show FAN1 (chassis fan) and FAN2 (CPU fan).

The third TAB can select which voltage values to display on the

software interface, and unconcerned friends can click on it.

There's nothing to say here

The fourth TAB allows you to select which fans to display on

the software world, and to control those speeds, and I chose

SPEED01 (case fan) and SPEED02 (CPU fan). This TAB has other

functions, and we'll talk about that later.

The fifth TAB is about some features of the software, so please

click on my Settings.

The seventh TAB (skip the sixth TAB), fan speed setting starts

now!

Yi? After the dot is open, is it blank? Don't worry, if you find

your control chip model in the chip drop-down menu, these

options prove the right choice. Change the PWM1 MODE and PWM2

MODE to Software controlled (must choose a Software controlled,

the fan by SPEEDFAN control, with the mainboard control

disconnection), and to remember it checked on the lower right

corner, final confirmation PWMOUT CLOCK has a value of 3 m. (all

of these options have a remember it.)

Once the software has some kind of error, or the operating

system has some kind of error that causes the software to work

abnormal, the fan's speed is still not controlled by the main

board, so there is still a bit of risk.

Then go back to the first setup TAB

See the expanded menu that appears after clicking on the plus

sign, which allows you to select the speed of the fan at a

certain temperature (which is ). Here, I chose

TEMP1 (my motherboard temperature) only to SPEED01 (my case

fan), and TEMP2 (my CPU temperature) only has to do with SPEED02

(my CPU fan). The other hard disk temperature, core temperature,

graphics card temperature and other extension menus are removed,

otherwise it will affect the software's judgment of fan speed.

Set the TAB below and another row, desired refers to the

temperature you want, I set here is 40 degrees, namely when

TEMP3 (i.e., my CPU temperature) temperature more than 40

degrees, fan began to accelerate, below 40 degrees, according

to the set speed the minimum; Warning is the warning temperature,

where the fan reaches the maximum speed limit when the

temperature reaches 50 degrees. (for "setting speed" please

look down). The show in tray on the lower right is set this

temperature to be displayed on the system tray, where I let the

CPU temperature display in the system tray.

My suggestion is that can be expected to raise some temperature

appropriate, such as the security of the CPU temperature at 60

degrees, don't play games when the CPU temperature in 48 degrees

or so, so expect temperature value can be configured on 51

degrees, warning temperature value is set in 58 degrees, it is

quiet and safe.

Now let's go to the fourth TAB.

First click here SPEED02 SPEED02 (in my here is CPU fan), look,

there was a row of options below, Minimum value is the Minimum

speed fan, I set a 0, Maximum value is the biggest fan speed,

I am a 100 set. See the Automatically variated in the lower right

corner? This check must be selected, otherwise the software

will not automatically adjust the speed. SPEED01 is about the

speed control of the main board fan, and so on.

, of course, you can set the maximum value as a low value (e.g.,

50%), so even if you play games made the CPU temperature, it

is running at 50%, although silent, be careful to burn the CPU.

Some fans will stop turning at a certain value (usually 35

percent), which should be noted. So friends can adjust their

speed manually to find the lowest value of their fan.

Finally, go back to the software master interface and use

Automatic fan speed to hook up, and the work is done!

Be worth what carry is, if your case fans also have automatic

speed control function, and your speed of case fans also has

carried on the set, so the software can be according to the CPU

temperature and case temperature at the same time to adjust the

CPU fan and case fans.
