This article describes the adjustment programspeed CPU cooler, video card and other elements of the PC. It does not matter whether you need to change the speed of the fans because of their excessive noise or because of overheating, SpeedFan will help in any case. The main condition for the proper functioning of the utility is the ability to adjust the coolers from the BIOS.
SpeedFan
SpeedFan - абсолютно бесплатная программа для adjust the speed of the cooler of the video card, the CPU and any other equipment with active cooling. The fan can be controlled in automatic or manual mode.
Before running the utility, it is desirable to disableautomatic speed change in the BIOS. If you ignore this condition, the proper functioning of the application is not guaranteed. After power-on, SpeedFan reads fan speed information and takes these values as the maximum. It follows that if the BIOS settings do not allow the cooler to spin up to the limit, then the utility will not be able to do this either.
For example, a CPU cooler when the SpeedFan is turned onRotated at a speed of 1000 rpm. The application will take this value as an upper limit and will not be able to increase the frequency when the CPU temperature reaches a critical level. If the computer does not turn off automatically, its CPU will fail.
First start
After starting the program to adjust the speedthe cooler will draw a window with a brief help. After studying the text, check the single point and close the window. After that, it will no longer appear on the screen.
Now the program will determine which equipmentthe active cooling with the possibility of adjustment is established and the reading of the sensors is considered. After that, the display will automatically display the list of fan speeds and the temperature of the main elements of the PC. In addition, in the application panel you can see information about the CPU usage and voltage.
To switch the language to Russian, go to the "Configure"> "Options" menu. Set the "Language" switch to "Russian". Click on "OK".
Main Window
Program for adjusting the speed of coolersRussian displays all the information necessary for the user in separate blocks. In the middle of the window there are data describing all the found controllers of the fans. Their names are Fan2, Fan1, etc. At the same time, the list can have a lot more coolers than there is in the PC. Opposite to some of them, the real speed of the fans will be displayed. Others will either show a value of zero, or "garbage" (less than 1000 rpm).
In contrast to the data describing the operation of the screws, there is a block of information about the temperature of the main components of the PC:
CPU - processor.
GPU is the core of the video card.
HD0 - hard disk.
There can also be "garbage" here.To determine which values are not real, you need to think logically. For example, the temperature of the devices in a running machine is unlikely to reach a level of 5 or 120 degrees.
This is the only drawback that the programto adjust the rotation speed of the cooler has not lost for all the years of development. It is worth saying that the official site offers a collection of necessary settings of the utility for popular PC configurations. However, it is often much faster to perform all the settings manually.
The main blocks of the utility
The utility block with the list Speed01, 02, etc.contains screws speed switches. It is indicated in percentages. The main task is to determine which switches from this unit are responsible for which fans.
Go to the first selector and change itthe value is 20-30%. Observe, the speed in front of which line "Fan" is changing. Now change the settings for the next switch. Remember or write down each match found.
If you can not identify the sensors, there ismeaning to use the utility AIDA64. Run it and SpeedFan at the same time. Change the values of the Speed switches, and in AIDA see which fans start to spin at a different speed.
Configuration
Go to the "Configuration" menu.Here you can define all the lines of the blocks in the main window clear names. For example, the CPU cooler rotation sensor is renamed to "TempCPU". To do this, click on any item in the settings, wait a second and click again. After that, the line will be highlighted and a cursor will appear in it.
Highlight the name of the desired sensor andattention to the bottom of the application window. Here it is necessary to write down which temperature of each PC device the program for adjusting the speed of the cooler will be considered normal. When the equipment has cooled to this level, the fan speed will be minimal. Also, specify the alarm temperature. Heating up to this level will turn on the maximum speed of the cooler.
To find out which values should be used, contact the official websites of the device manufacturers of your PC.
Now click on the "+" next to the name of the sensor. Remove all the checkmarks from the "Speed" list. Leave only the one that corresponds to the regulator of this device.
Go to the "Fans" tab and, if necessary, rename them in the same way as the sensors. Unused uncheck by unchecking the boxes.
Speed
To program for adjusting the speed of the coolerperformed automatic control, open the "Speeds" tab. Select the line for the desired fan and rename it as you see fit. Now pay attention to the bottom block of the window. There are two points:
"minimum" - the level of the minimum revolutions of the cooler,
"maximum" - the maximum.
All values are given in percentages. Never enter a number here equal to 100, because the fan will spin up completely when reaching the peak temperature, which was tuned earlier.
At the end of the configuration, check the box next to "Autochange" and click "OK."
Extra options
In addition to the settings listed above, the program foradjusting the speed of the cooler has additional parameters. All of them are in the "Configuration"> "Options" menu. It is impossible to describe them all in a short article, only the most necessary ones will be listed here.
A tick in front of the text "Running Collapsed"will cause the program to turn on without displaying the main window. This is very useful if the utility is loaded automatically with the operating system. Without setting the checkbox, every time the OS is launched, the utility window appears on the display.
The checkbox next to "Collapse when closing" will allow the application to continue working, even if the user clicked a cross.
Checkbox "Full speed fans afterexit "is necessary to prevent problems after the application is closed.If not to mention it, the program for adjusting the speed of the cooler of the notebook will leave the rotation speed of the screws at the level at which they worked at the time the utility was shut down, which could lead to overheating and breakdown of the PC.
