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

sign in a second.

Note: TEMP1, The temperature of the representative is

different, and the friends have to decide for themselves which
