SpeedFan is a utility that will describe in detail the condition of your PC or laptop. In particular, the application can give you information in real time. Statistical information is provided on all vital parameters for a computer: power supply operating mode, processor and video card temperature, cooler rotation speed, load random access memory and many other data).

In addition to all the above parameters, the SpeedFan program will detect whether there are errors in your system, which it will try to correct if possible (for example, it will increase the speed of the cooler to lower the processor temperature).

Well and main feature SpeedFan utility, as you may have guessed, is the ability to both reduce and increase the speed of the cooler on a laptop or PC, which will undoubtedly please those users who believe that their fans do not cool the system very well - in this case, it is better to increase their rotation speed.

When you start the program, the first thing that will open is the “indicators” insert. It will collect and display all the basic information about your system. The Speedfan program has a warning algorithm that signals if the equipment is operating outside the range normal temperature processor, overheating is detected or, on the contrary, sudden cooling is noticed.

Such events are marked on the monitor screen with a special label in the form of a light, which should draw the user’s attention if the equipment operates in non-standard temperature conditions.
But you should not be wary of such alerts, since the equipment tends to heat up, and the SpeedFan program will highlight the changes that have occurred even if it deviates from the norm by one degree.

In such cases, look at the data sheet of your device and find out what temperature is considered normal for the processor, so that you can be completely calm and not worry when the normal temperature of the processor changes.

If you want to analyze the condition of the hard drive, then for this purpose SpeedFan has a diagnostic function using S.M.A.R.T technology. This type The test has 2 operating modes - extended and short. Upon completion of the hard drive diagnostic process, a corresponding column will appear with errors (if any are found), which are displayed in the form of icons: green, orange and a “STOP” icon with white bricks.

What each label means is clear on an intuitive level - the first is all good, the second is working at the limit, and the third label indicates the presence of malfunctions.
The SpeedFan program can be downloaded in Russian for free, the only thing you have to do is switch the language from English to Russian, if English is installed by default.

The main purpose free program SpeedFan is that the utility carries out detailed monitoring of system cooling, and this program is used in cases where there are serious suspicions about overheating of the microcircuits. In any case, if it detects overheating problems, it will try to increase the speed of the cooler on the laptop or PC.

Often, users do not even know that they can control the speed of fans if they are connected directly to motherboard. The excellent SpeedFan program allows you to do this and more. The main advantage of the program is its wide functionality and the ability to use it for free.

In this manual we will show you how to use the SpeedFan program. We will tell you with an example latest version SpeedFan 4.52, but in our experience you can easily use previous versions of the program, since there are not many differences there. We’ll also look at how to configure the SpeedFan program to make it easier to use in the future.

First of all, you need to download and configure the program for comfortable use. The first thing we included in the process of setting up the program was changing the interface language, since most users prefer the Russian interface language.

Official site: www.almico.com/speedfan.php

In the interface of the SpeedFan 4.52 program, six tabs are available to the user.

• Indicators— main program window with the necessary settings (component temperature, fan speed, voltage, CPU load).
• Frequencies- ability to control processor frequencies.
• Information— here you can see information about RAM.
• Exotic— values ​​of all sensors for all computer components.
• S.M.A.R.T- here you can look at your health hard drives computer.
• Charts- overview of fan speed, temperature and voltage graphical form for each component.

Before moving on to the next step, you need to check some settings. Because by default the motherboard controls the fan speed. If we want to allow the ability to change the fan speed manually, then you need to go to:

1. Indicators > Configuration > Temperatures and look at the name of the chipset sensor in the column Chip.
2. Next, open the settings tab Additionally and select the desired chipset.
3. In which we change the property value PWM1 mode PWM2 mode, PWM3 mode on Manual, Manual PWM Control or Software Controlled.

Through the SpeedFan program you can increase the speed of all coolers that are directly connected to the motherboard. Increasing the cooler speed may be necessary if your computer or laptop is overheating.

In this way you can reduce the speed of the cooler through SpeedFan. This will reduce the speed of the fans when they make noise on the computer and you don’t know what to do. If you need to reduce the cooler speed, set the Pwm1 value to less than 100%, since at a value of 100 there will be a maximum fan speed.

A more complex method is to separately set the sensor temperature at which the fan speed will increase to maximum and separately set the minimum temperature.

And also increasing the minimum speed value can significantly reduce, and thereby increase its lifespan.

SpeedFan doesn't see fans

Often users encounter a problem when the SpeedFan program does not see one cooler on the computer, or does not see the processor cooling fan on the laptop at all. What to do first in this case:

• If the problem is on the computer, then be sure to check that all fans are turned on directly to the motherboard, since if you supply power directly from the power supply, then you will not be able to programmatically control the speeds.
• Next, if you are using a laptop, then in Bios look for items related to automatic fan adjustment. Need to find CPU Fan Control, CPU Q-Fan Control or even CPU Smart Fan Control and disable them by setting the value Disabled.

After these steps, the problem when the SpeedFan program does not see the fan on the laptop will be solved. And also, there are very old motherboards that do not support changing the fan speed at all.

conclusions

The SpeedFan program has truly excellent functionality and offers powerful tools for monitoring the temperature of components. But as a bonus there is additional functionality, such as the ability to monitor temperature graphs or even check the status hard drive. More powerful programs can be found in the article.

In this article, we showed how to use the SpeedFan 4.52 program and how to configure it correctly. Although at the time of writing the current version of the program was 4.52, previous versions the main functionality works similarly. And also suddenly your SpeedFan does not see the fan or refuses to change the value at all, then we recommend that you take a closer look at the problem above.

As the name suggests, the SpeedFan program (eng. Speed ​​- speed, Fan - fan, cooler) is aimed at adjusting the speed of coolers in system unit, but the developers included many others useful features. The list of program capabilities includes analyzing the state of the hard drive, adjusting the frequency and voltage of the motherboard, presenting the received data on a graph in real time, and recording data to a file.

Also one of the most useful features of the program is the “Events” function - these are various actions (e-mail sending, application execution, signal or pop-up message) if the assigned parameter is not normal. The most simple example There will be a pop-up message when the processor becomes “hot” (its temperature has risen above the specified parameter).

Possibilities:

• cooler speed adjustment;
• analysis of hard drives using data from S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology);
• event function.

Principle of operation:

SpeedFan is a program that reads temperature, fan speed, voltage, etc. from your computer and displays them. So this data is no longer hidden inside the PC.

Pros:

• online database of hard drives for comparing the received data with the factory data;
• adjusting system bus frequencies and cooler speeds;
• SpeedFan can access information about the status of IDE, SATA, SCSI hard drives;
• can display voltage, fan speed and temperature;
• there are command line launch options;
• adjusting the cooler speed depending on the temperature inside the PC;

Minuses:

• receives data and regulates it at the lowest level; this is not suitable for every equipment;
• The manufacturer is not responsible if SpeedFan causes any damage to the system;

SpeedFan is an extremely powerful tool. The program can be very useful, it will help find reasons for unpredictable reboots or warn when HDD it's time to replace. SpeedFan can help you significantly reduce noise at work or while watching a movie. But it requires access to many resources on the motherboard; not everyone “likes” this type of access.

Every PC user should be able to correctly configure the cooling system in order to avoid overheating of the device and premature failure of components due to high temperatures in the future. Or to . You can control the operation of the cooler using special programs or BIOS settings, this is exactly what we will talk about in this article.

BIOS Settings

Many of the famous laptop manufacturers such as Asus, Acer, HP, Lenovo, Samsung have made it possible to control the laptop cooler from the input/output system or “BIOS”. This method good because it doesn't require installation third party programs, all that is required is:

I would like to draw your attention to the fact that the settings may have slight differences depending on your Bios version. Don't be alarmed, the overall scheme is identical.

SpeedFan program

A well-known utility, it can be used to control a laptop fan, regulate speed at certain temperatures, and monitor the status of the hard drive. A few more big pluses are that it’s free, a simple and clear interface and support for the Russian language, so feel free to use it.

So, let's look in more detail at how to configure the cooler on a laptop using SpeedFan:

Also in the “Speeds” tab you can set additional parameters for changing the speed of rotation of the blades. There are only two options here; by changing them, you can easily change the lower and upper speed limits.

Riva Tuner program

Another small but very convenient application, designed to control and monitor the operation of the fan. It is also absolutely free and suitable for any version of Windows.

It is quite easy to change with its help; for this you need:

After this, the laptop fan should start running constantly and at the specified speed.

MSI Afterburner

Professional free utility, designed primarily for overlocking (overclocking) cards from MSI, is suitable for both AMD and Intel. It provides us with quite a lot of possibilities, from monitoring the state of the board and adjusting the voltage on the GPU to controlling the cooler.

I would like to note that all the settings are on the first screen, which in my opinion is very convenient. In order to change the speed of the cooling system, you need to move the slider to the right in the “Fan Speed” section.

For automatic adjustment, a separate “Auto” button is provided; after pressing it, the speed of revolutions will change depending on the load on the laptop’s video card.

Due to heavy load, computer hardware can often overheat. In particular, this applies to components installed on the motherboard such as hard disks, video cards, etc. Allows you to control the parameters of fans (coolers) software called SpeedFan. What is this application, how to configure and use it correctly, read on.

SpeedFan program: what is it and what is it for?

The application itself is a software control component that allows you not only to monitor the recommended, critical (peak) or current cooling parameters of hardware devices, but also to configure the coolers that are responsible for these processes.

In other words, the same SpeedFan program for a laptop is not only a diagnostic tool, but also a powerful tool that gives the user complete control over the temperature readings of the fans, their rotation speed or operating modes, with subsequent determination of the results of the set parameters.

Nuances of installing the application

So, let's look at the SpeedFan application. How to use the program will be discussed a little later, but for now let’s pay attention to some points related to the installation of this software product.

First, you should download the installation distribution from the Internet using a trusted source (website). If you download the application from the official resource, the English version will be presented there. You can also find the SpeedFan program in Russian on the Runet. In any case, before starting installation, the downloaded distribution should be checked for potential threats.

After running the executable installation file, you need to follow the instructions of the "Wizard", but during the installation process there will be several initial tests. In addition, you should note that in order to launch the installed application when Windows XP starts, its shortcut must be placed in the startup menu. For higher versions of the system, you can use the UAC slider, setting it to the minimum position, or add the program launch to the “Task Scheduler”.

Preview of the program interface

After installation is complete, launch the SpeedFan application. How to use the program will be clear if you pay attention to its interface (the main window that appears when you first start).

There are several main tabs, the number of which is different versions applications may differ. The indicators tab contains basic information regarding temperature values ​​and voltage of system components, fan speeds and operating modes, load central processor etc.

The frequencies tab is used to overclock the processor and allows you to change the frequency according to the specified operating conditions. Please note: it is not recommended for ordinary users to do such things without special knowledge under any circumstances!

The next information tab is dedicated to RAM. By the way, based on the parameters shown, you can purchase a version of the program that will fully match the installed motherboard, which will increase the reliability and performance of the application in relation to system components.

S.M.A.R.T tab gives full information about work and state of rigid disk computer system, and also provides some opportunities for conducting basic hard drive tests.

Finally, the graphs tab in visual mode gives a complete picture of the conditions under which temperature readings change computer components in real time. To select a specific component, use the drop-down menu.

SpeedFan application: how to use? Initial setup

Now a few words about the initial settings. First, we use the indicators tab, where we enable or disable the indicators used. For the selected (highlighted) element, you can set the desired (Desired) and alarm (Warning) temperature.

The desired value, for example for a processor, should be set based on the idle temperature (when the cooling cooler is not heard). If this value is, say, 33 degrees, the desired indicator should be 35-37 degrees. Typically, the warning temperature is in the range of 50-55 degrees.

In any system there are unused sensors, such as LM75, so they need to be disabled, as well as incorrect temperature readings. The remaining indicators can be renamed and then arranged by simply dragging the mouse to the desired position. The same can be done with fans.

Setting fan parameters

Now the most important thing that is in the SpeedFan program. How to use the simplest settings is already clear. Let's consider setting the main controlled parameters.

The speeds are configured on the tab of the same name, and the actions are similar to those described above (renaming, deleting, arranging, setting custom values).

Next, go to the Readings tab, which displays the speed range of CPU0 and CPU1. Initially, the values ​​are set to 100%. You cannot change all speeds, and the program will not allow you to do this. But, as a rule, the application for PWM sensors resets two of the four parameters, removing the checkmarks from them and leaving only the two priority ones.

Any sensor can only affect the rotation speed of only one fan. Theoretically, it seems possible that all speeds can be optimized, but in practice, the temperatures of CPU0 and CPU1 are associated only with speed indicators of the same name.

Another thing is that the application can be notified that the CASE speed parameter will be enabled for two fans (check the boxes next to CPU0 and CPU1 in the corresponding field). You can also use automatic setup speeds, but they will not change automatically. Therefore, for each fan where such a setting is expected, you need to set the Automatically variated parameter. Only after this the speeds will change depending on the temperatures set on the corresponding tab.

And you should not use 100% speed, since the noise can be quite strong. For example, if the first cooler operates almost silently at the 65% position, and the second is noisier, automatic adjustment can be removed and the values ​​set in the range of 65-100% (first cooler), and 65-90% (second cooler). But still, when a critical heating threshold is reached or exceeded, regardless of the set values, the application uses the rotation rate of both fans to 100%.

Conclusion

It remains to add that this program should only be used by advanced users who have initially studied all the documentation on the devices installed in the system and the parameters that they support. And even more so, it is not recommended to overclock the processor or change the system bus frequency without special knowledge, since this can lead to the most unpredictable consequences. But for complete monitoring of the state of all “hardware” components of the system, the application is just perfect, because with its help you can track potentially dangerous conditions of some devices, and then disable programs or services that affect them the most, causing unreasonably high loads.
