• How to use the SpeedFan program. Guide to using SpeedFan

    Often, users do not even know that it is possible to control the speed of fans if they are connected directly to motherboard. This and more allows you to do great program SpeedFan. 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 SpeedFan program. We will talk using the latest version of SpeedFan 4.52 as an example, 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 website: 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 in 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 with a value of 100 there will be maximum speed fan

    More the hard way 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, you will not be able to programmatically control the speeds.
    • Further, if you are using a laptop, then in Bios look for items related to automatic adjustment fans. Need to search 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

    SpeedFan has really great functionality and offers powerful tools to control the temperature of components. But there is a bonus additional functionality, such as the ability to observe temperature graphs or even check state of hard disk. 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.

    A fairly common problem among all hobbyists. computer games And graphic editors: overheating of the processor, video card, as well as unstable work cooler. To solve this “illness” a program called Speedfan was created. This simple utility will help you monitor the temperature of all components that may be subject to overheating, even the hard drive. In this article you will get to know the program better and learn how to use it.

    Installing and downloading the program

    The Speedfan program can be freely downloaded from the official website http://www.almico.com/speedfan.php

    Go to the “Downloads” tab.

    On this page you will see another section with the same name “Downloads”, and in it there is a small link with the latest version of the program. Click on it to start the download automatically.


    The program installer takes up very little memory, so it downloads very quickly. Once you run it, you'll need a license agreement. Click on the “I Agree” button.


    In the next tab, several items will appear, next to which you need to tick. This is adding shortcuts to the desktop, to the panel quick access. Click “Next”.


    Select the program installation directory. If you have two disks, then do not install it on the local one, as it should be allocated for the required systems. You can select a folder using the “Browse” button. Click “Instal” to start the download.


    The program will install in just a few seconds, you need to wait until the line at the top is filled with green.

    At this point, the installation of the program is complete, you can begin setting up and working.


    How to set up the Speedfan program

    Now you can adjust the rotation speed of the fans in the cooler, control the temperature of the video card, hard drive, central processor.

    • Access the program via a shortcut on the desktop or in the Start panel.

    • The entire utility interface is on English. You only need a little knowledge to easily understand all the components.
    • All configuration takes place in the configuration section, click on the “Configure” button to enter it.

    A new window will open in front of you, containing many tabs. First go to “Temperature”. Here you can configure the display of component temperatures. Check all of them, namely:

    • GPU – your video card;
    • HDD hard drive computer or laptop;
    • Temp – sensors on the motherboard;
    • Core – CPU cores that must always be cooled.

    All these parameters must have their own maximum temperature, upon reaching which the program will notify you and speed up the operation of the fans in the cooler. At the bottom of the window you can set values ​​for each component separately.

    Click on the component, enter the value in the “Warning” column below, if you know what the temperature limit for this component is. For example, for older video cards, heating above 93 degrees is not recommended.

    By going to the “Speeds” tab, you can set your cooler speed values. This contributes better cooling, however, wears them out more.


    Now apply all the parameters by clicking “Ok”, exit and go to the “Charts” window. These are charts that are easy to view. Check the boxes that concern you most. This way you can track the metrics in the chart.

    Now that everything is set up, you can simply go into the program and look at the temperature readings, follow the diagram, change the cooler speed at your discretion.

    Please note that sometimes it is not practical to change the speed of rotation of the screw, as it will have to be lubricated more often. If you don’t know how to do this, then everything will become even more complicated, because the special rubber gasket inside the cooler will quickly wear out without lubrication, and as a result it will become unusable and begin to make loud sounds.

    To prevent this from happening, do not set new values ​​on old equipment. Coolers wear out relatively quickly, it is better to take care of them - pay attention to special cooling pads if you need to lower the temperature.

    AND personal computers People often wonder how to use Speedfan 4.51.

    You can download the program for Windows through the official website of the developer Almico.com.

    Program features:

    1. Function of dynamic control of fan speed on a laptop or PC;
    2. Real-time CPU temperature monitoring;
    3. Interaction with all available chips for system monitoring;
    4. A function that allows you to change the system bus frequencies (works only with several types of motherboards);
    5. Full display of hardware device operating statistics and diagrams of their impact on overall system performance;
    6. Identification of the temperature of the device's hard drive.

    Also, in addition to all the above features, updated version software has support latest versions popular models laptop processors.

    Available version software Speedfan, which is suitable for any computer, is portable rus. This version does not require installation on the system.

    You can work with the application by simply opening the executable file.

    Advice! If your computer is too noisy (heats up) and the fans are not speeding up, you should use the program, because it can solve the problem of constant overheating and spontaneous shutdown of the system.

    Setting up the program

    In order for the application to work stably and regulate the operation of all hardware components of the computer, it must be configured.

    Let's take a closer look at how to use and how to set up the program in a few minutes.

    This method settings and instructions are suitable for any version of the program, because they all have the same interface:

    • Use the program in English, not Russian. This way you can avoid incorrect display some discovered system parameters;
    • Run the program as administrator, as shown in the figure;

    • After starting the program, you need to wait a few seconds. At this time, the utility determines the hardware components that will be worked with in the future;

    • To start the setup process, click on the configuration button, which is located on the right side of the main program window. The following window will appear;

    • The window is divided into several tabs. The figure above shows a tab with component temperatures. The indicators in the second column indicate the motherboard chip from which the device is read.
      This way we can determine which component's temperature is shown. Let's start setting up the temperature display, for example, of a video card. It corresponds to the GeForce Video card chip. Click on the device.
      At the bottom of the window you can see two temperature regulators (on the left is the desired temperature, on the right is the alarm temperature). All that is necessary is to set the indicators at the user’s discretion;

    • Uncheck all devices named Temp. They have not decided on the program and it is impossible to measure their temperature;

    Disable undetected devices

    SpeedFan - free program, designed to control fan speeds, as well as to monitor temperatures and voltages in computers with motherboards with hardware sensors. The program can also display S.M.A.R.T information. and temperature hard drive, If this opportunity supported by hard drive. It is also possible to change the FSB on some components and support for SCSI drives. But main feature This program is that it can change fan speeds depending on current temperatures (this feature is not supported by all sensors). This reduces noise and energy consumption.

    This manual is suitable for any version SpeedFan.

    I recommend using the program's English interface. This will avoid problems with resetting the names of temperatures and fans, and the English text looks more concise and compact.
    Setting up the program
    Press the button " Configure».

    Before us is the first tab - “ Temperatures", displaying the sensors installed on the motherboard and current temperatures with standard parameters.

    Let's start setting up


    You can see that all available temperature values ​​are displayed, which SpeedFan was able to detect. In the column " Chip» the sensor chip is indicated. IN in this case we have three different chips: one W83782D and two LM75. We can tell the difference between the two LM75s due to the different addresses ($48 and $49). The LM75 chips, in this case, are actually clones created by the W83782D, and we will not pay attention to them since all temperatures are available directly through the W83782D. But this is not always true. Winbond chips can be configured to actually hide real temperature, received from the main sensor. In this case, you need to work with LM75. So, choose the desired temperature. For example, we chose TEMP02.


    We select “Desired” and “Warning” temperature values ​​according to our wishes. Please note that we say “wishes”. You are free to set any values. But you shouldn’t go to extremes and set values, for example, around 15 degrees. This will not bring the desired result.

    Ideally, thresholds should be set like this. Select a comfortable CPU fan speed for idle mode (usually set so that it is not audible), and now remember what the processor temperature is at this fan speed. For example, if the processor temperature at idle is 35 degrees, then the desired ( Desire) you need to set more, for example, 37-40. Then, when this threshold is exceeded, the fan will accelerate to the upper value ( Warning) in its settings, and when the temperature starts to fall and crosses this mark ( Desire), then the fan will slow down.

    1. If the sensor temperature is less Desire, the fan will rotate at the Min speed (set for it).

    2. If the sensor temperature exceeds Desire, but less Warning- the fan will rotate at speed Maximum Value(usually set<100%).

    3. If the sensor temperature exceeds the value Warning, then the fan starts rotating at 100% of its possible speed.


    As you can see, we first have to select the temperature, then we can select its parameters. You can also rename the name of the temperature (using the mouse or clicking " F2"). The new name will be more clearly displayed in the main window.
    In modern systems there are usually a large number of different temperature sensors. To correctly identify them, it is recommended to run the AIDA64 program in parallel and rename all the necessary temperatures according to its readings, checking the same indicators.

    We have renamed TEMP1 and TEMP2 to CPU1 and CPU0.


    So we're done renaming and setting parameters for each temperature. Since in our case the highest temperature in the system is the “Case” temperature, we decided to display it in the taskbar (checkbox “ Show In Traybar»).

    Now we must hide in the main window those temperatures that are unused. In our case, these are the indicators of LM75. Not every system has unused sensors, but it also happens that there are unconnected sensors on the motherboard that are reporting incorrect values ​​(like -127 or something like that).


    Uncheck any temperatures that you think are not useful or are incorrect.

    You can now organize the temperatures displayed in the main window. All we have to do is use drag&drop to move them up or down.


    So, the first part of the setup has been successfully completed, and we have achieved the following result:

    Fan settings


    Just like with temperatures, we can rename the fan names...


    ... remove unused ones from the main window...


    ... and organize.

    Setting speeds
    These are the default settings for this system. You can set your minimum ( Minimum value) and maximum ( Maximum value) power values ​​for each fan.

    Don't forget that not every motherboard has the ability to control fan speeds. This, first of all, depends on what sensors can be installed on it and detected by the program SpeedFan. The same goes for temperatures, voltages and fans. Not every sensor chip can monitor all of these parameters. SpeedFan displays all the information available to it.


    As usual, we can rename...


    ... remove unused ones from the main window (W83782D has 4 PWMs, but you are unlikely to use them all) ...
    ... and organize.


    We will not describe the voltage settings here, because... They can also, similar to other parameters, be renamed, hidden and rearranged.

    Assigning speeds to temperatures

    Now the main window looks much better than when you first launched the program. The flame icons are gone and unnecessary options no longer clutter the window :-)
    But we still have CPU0 speed and CPU1 speed equal to 100%. It is necessary to reduce the fan speed. Please note that you will not be able to change all speeds. This depends on the sensors and controllers installed on your motherboard. Since, in this case, we have a W83782D, we have the ability to change many parameters.


    Going back into the settings panel, we can see that the CPU0 temperature is associated with all available speeds, two of which have checkboxes and the other two do not. This happens because we hid some speeds from the main window and the program, assuming that we don’t need these speeds, automatically unchecked them.
    Each PWM can increase or decrease the speed of one fan. Theoretically, each fan can affect any temperature. Here we are telling the program that CPU0 speed and CPU1 speed (which are linked to PWM2 and PWM1) both affect CPU0's temperature. This means that SpeedFan will try to speed up both of these fans when the CPU0 temperature is too high and will try to slow them down when the temperature drops.

    This is how we have formed the CPU0 temperature until now. But this is not what actually happens in this system. Here, the temperature of CPU0 changes under the influence of the speed (fan) of CPU0 and the temperature of CPU1 changes under the influence of the speed of CPU1.

    We change the configuration accordingly.


    There is one more temperature that we would like to control: the temperature " Case" This temperature actually changes under the influence of both fans. We can easily tell the program about this.

    Automatic speed change

    As you can see, when the “ Automatic Fan Speed", the speed does not change automatically. Therefore, we return to the tab “ Speeds» settings panel.


    Select the fan speed we need and put a tick in the “ Automatically varied» (Automatic change). This needs to be done for all coolers whose speeds are planned to be controlled automatically.
    Now the speeds of the fans we need will change depending on the temperatures we set on the “ tab Temperatures».

    By default, SpeedFan can vary each speed from 0 to 100%. If you uncheck the " Automatic Fan Speed» (Automatic fan speed control), SpeedFan will stop automatically controlling speeds.
    Setting the desired speeds


    One of the fans in our system is quite quiet already at 65% power ( Minimum Value). That's a good thing because it's still running at 5,700 rpm. The other fan is noisier. Therefore, the value of its power will be slightly different from the first one.

    90% power ( Maximum Value) the second cooler is enough to cool the central processor to an acceptable temperature. At 100% the noise level becomes quite high.


    With these settings, the program will dynamically change the speed of the first fan from 65 to 100%, and the speed of the second - from 65 to 90%.

    Please note that if " Alarming» ( Warning) temperature reached, SpeedFan will set the fan speed to 100%, regardless of what we set previously.

    Here we describe the basic settings that need to be made for the program to work successfully.

    1.1. Setting up Advanced Fan Control.
    In latest versions Speedfan it became possible to set a curve depending on the fan speed versus temperature - Advanced Fan Control. You can see detailed information on setting up at the link provided. I note that if you are not satisfied with the accuracy of placing points, open the file speedfansens.cfg and there set the points directly with numbers (value ControlPoints, after the change the program must be restarted). Please note that the minimum and maximum fan speed thresholds on the tab Speeds have higher priority than the curve Advanced Fan Control. Temperature is the same: if a point on the curve goes beyond the boundary Warning on the tab Temperatures, the fan will start rotating at 100% speed.
    2. Enable autoloading.
    The program is configured, but now we need it to run every time the computer boots. There are no problems with Windows XP, you just need to drop the shortcut into Startup. But with Windows 7 and 8 it’s more complicated.

    In Windows 7 with default UAC settings, the program may not start by simply moving the shortcut to startup, so the easiest way is to lower the UAC slider to a minimum. If this does not suit you (and in Windows 8 this may not work), then the Task Scheduler method will help. Right click on My Computer - Management - Task Scheduler - Task Scheduler Library. On the panel on the right - Create a task. On the tab General enter the name of the task (optional) and check the box Run with highest rights. Tab Triggers - Create - On login. Tab Action - Create - Run program- please indicate Speedfan.exe button Review. Click OK- a task will be created. You can check its launch immediately: right click - Execute.

    3. F.A.Q.
    Q: How can I find out what temperature sensors Temp1, Temp2 correspond to?
    A: Run AIDA64 in parallel and find the same readings. Rename the previous names to the desired ones.

    Q: Help! One of the sensors (aux) shows 127 (-125) degrees!
    A: If the readings of this sensor are always the same, feel free to remove it from the list of displayed ones.

    Q: After changing the names of the sensors and fans to their own, the next boot the previous names vent1, temp2, etc. appear again. I have to click “Configuration - OK” and only then my names appear instead of vent and temp.
    A: Use the English interface language.

    Q: I did everything as written in the program settings, but the fan on the processor cooler does not change its speed.
    A: Make sure the four-pin fan is inserted into the four-pin header on the motherboard. If the fan has only 3 wires, then speed control is impossible (with rare exceptions).

    Q: I have a three-pin connector on the motherboard and the same on the fan / I have a four-pin connector on the motherboard and the same on the fan - the speed still does not change.
    A: Change the PWM x Mode value (where x is the desired fan) in the IO settings of the chip (Configure - Advanced) to something like Software Controlled or Manual PWM Control, remembering to check the “Remember” checkbox


    Q: The program shows that the voltage on the 12V line is only 9V. What to do?
    A: You should not trust this data. The only correct solution is to measure the voltage using a voltmeter.

    Q: I'm planning to upgrade my operating system, but I don't want to have to reconfigure the software. How can I save all settings?
    A: Copy 3 files from the program’s working folder: speedfanevents.cfg, speedfanparams.cfg, speedfansens.cfg.

    Q: Fan speed is huge. It's fine in other programs.
    A: First change the Fan Div value in the IO settings of the chip (Configure - Advanced), if that doesn’t help - Fan Mult.

    Please indicate any errors or typos you notice in the comments.

    On this page of the site we have published detailed instructions with screenshots on how to use the SpeedFan program for beginners. Here you will find information on how to increase or decrease the speed of the cooler (fan) and introduce you to the program interface. If you have questions about working with SpeedFan, please leave them in the comments at the end of this article.

    Working with the program:

    After installation, you can change the language. To do this, you need to go to the Configure button, to the Options tab and there we find the Language item. Change the language from English to Russian and confirm.

    The Metrics tab shows basic information.

    If you want to control the fan of your computer, then to do this you need to find which fan you need. If, for example, you need to control a CPU fan, then you need to look for the registered CPU (central processing unit) first. There are times when data is not displayed in the “Indicators” tab. If you encounter this, then go to the “Configuration” button to the “Fans” tab.

    So let's say you want to increase the fan speed. Go to the “Speeds” tab and here select the CPU (fan central processing unit). Just below we set the automatic power setting by checking the “Auto change” checkbox and setting the power boost.

    The Temperatures tab will help you know if your computer's temperature gets higher than the set temperature.

    In the “Report” tab you can enable reporting.

    If you go back, click on the S.M.A.R.T tab and select one of the hard drives, you will get an analysis of your computer. When you want to get a full description, then click on “Perform an in-depth online analysis of this hard disk”.

    This shows an analysis of your hard drive according to S.M.A.R.T. The page is only available in English, but in the screenshot below you can see the translation of the tab's functions.

    The “Graphs” tab is used to know the temperature and fan speed of the devices you need and thus compare them.

    Determined by:

    • System - the computer itself and its case.
    • GPU - graphics processor.
    • INF - hard drive.
    • Core - core.

    For example, you need to know the temperature of your hard drive and GPU.
