Download the program for auto cooler settings. SpeedFan is a free program for adjusting the speed of coolers

Good day, dear friends, readers, visitors and other personalities. Let's talk about the program today. speedfan which is clear from the title.

I think that you all remember the article "", which told you a lot of all sorts useful information about heating the contents of your iron friend and a few words about how to deal with this heating, namely, for example, by or.

But what if everything is more than normal with temperatures, and the computer is buzzing like damn? The answer is simple: you need to somehow regulate the speed of the fans, because they are the cause of noise in most cases. Just how to do this will be discussed in this article.

Introduction about computer cooler speed

Let's start with how the adjustment, if any, occurs at all.

Initially, the rotation speed is determined and set based on the temperature readings and the settings specified in .

The motherboard, in turn, does this by changing the voltage / resistance and other nuances, smartly controlling the number of revolutions ( RPM), based on the settings you specified, as well as the temperature of the computer components as such and inside the case in general.

However, not always, despite all the smart adjustment technologies ( Q Fan and others like them), it clearly does its job, and therefore the twisters on, either work too hard (often this is exactly what happens), which creates non-illusory noise, or too weakly (rarely), which increases temperatures.

How to be? Options at least three:

• Try to set everything up BIOS;
• Take advantage of specialized programs;
• Or physically pick something with power (or by buying all sorts of reobass and other physical devices).

Variant with BIOS, is far from always justified, because, firstly, such technology is not available everywhere, secondly, it is far from being as intelligent as it seems, and, thirdly, it may be necessary to change everything manually and on the fly.

Additional information on speed

Field " CPU Usage" and the indicators next to it show the current download and its . Buttons " Minimize" and " Configure" allow you to minimize the program or open its settings.

Check mark " Automatic fan speed"turns on automatic rotation adjustment. You can use it, but there is no sense, as such, in general, otherwise why did you install this program at all if everything suited you as it is?

IMPORTANT! The list of indicators does not necessarily refer to this or that cooler, as it is signed in the program! That is, if it CPU or Fan1, - does not mean that this is the speed CPU cooler, because it all depends on which slot the fan is connected to by the assembler (or you) directly on the motherboard and how correctly the program reads data about this connector! Ideally, determine the speed by changing the value and looking into the open case.

Details on various controllers in SpeedFan

I tell you what is what in the case of the rotation speed indicator (measured in RPM, i.e. in the number of revolutions per minute):

• SysFan (Fan1), - shows the rotation speed of the spinner (I mean the fan) connected to the SysFan socket on the motherboard. It can be either a cooler installed on the chipset, or any other cooler simply plugged into this connector (all connectors on the motherboard are labeled accordingly);
• CPU0 Fan (Fan2), - shows the speed of rotation of the knob on the processor, i.e. the fan plugged into the connector CPU_Fan on motherboard;
• Aux0 Fan (Fan3), - tells about the current rotation speed of the fan connected to the connector AUX0;
• CPU1 Fan (Fan4), - similarly CPU0, but only if you have a second processor or cooler slot labeled CPU1_Fan;
• Aux1 Fan (Fan5), - similar to Aux0, i.e. shows the rotation speed for the cooler plugged into the connector AUX1_Fan;
• PWR Fan (Fan6), - it happens that the rotation speed of the cooler installed (not always) is indicated here, or simply the speed of the fan that is plugged into the connector PWR_Fan on there.plata.

Once again, I note that each parameter here corresponds to motherboard connector and almost any cooler can be plugged into any of them, and then its indicator will be displayed in the corresponding column.

Naturally, this should be stuck through a small 3-pin-connector to the motherboard, and not powered by the power supply. To make it clear, let's show you a photo.

Cooler connectors and their photos

The correct connector and the correct socket (the socket in the picture 4-pin, and the connector 3-pin) to be able to watch and adjust the rotation speed:

"Wrong" connector, i.e. power supply from the power supply, which not allows (see note above) to monitor and, often, change rotation speed using the program, bios and anything else:

Tobish, if during assembly some of your coolers (for example, case coolers) are powered from the power supply unit by the above connector, then I recommend getting into the computer and plugging them into the motherboard so that you can control the fans as you like.

To the right of the above values, as I said, temperatures are indicated. For me personally, they are not filmed accurately and adequately enough, and therefore I recommend using analogues like or and drawing conclusions based on them.

And now the most delicious. Below, opposite each inscription Speed01-06(or in later versions of the program it could be Pwm1-3,Pwm1-3), there are arrows, by clicking on which we can adjust the rotation speed of a particular fan. In fact, they are what we need. Try playing with them by moving them up and down and you will see how much quieter / louder your computer can work.

By the way, to understand which column regulates the speed of which cooler, just watch the change in values RPM. Naturally, it is not recommended to turn off the fans completely, so as not to burn something and, of course, that it is necessary to simultaneously look at the temperatures when adjusting the values.

Disable/Enable Auto Speed ​​Control in BIOS

Depending on the type of motherboard, version and type of it BIOS and other factors, the program may not work if BIOS turn on or off adjustment automatically or based on preset patterns.

Therefore, it is possible that if you encounter problems with the program and it works (or does not work), or you want to entrust the control of the motherboard, you may need to enable or disable the built-in BIOS adjustment system. Approximately, depending on the version, this is done like this:

Those Q Fan pregnant enable includes automatic control based on the given parameters in BIOS, a Disable disables this option. Depending on the type BIOS, as you can see in the screenshots above, this option can be located on different tabs and look different. It is also possible that you need to switch CPU Fan Profile With Auto on the Manual or vice versa.

Unfortunately, it is impossible to consider all variations, but one way or another, this tab is always present on any computer (with the exception, perhaps, of laptops) and you can find it there. In particular, it is not always called Q Fan, it could be something like CPU Fan Control, fan monitor and in a similar way.

In a nutshell, something like this. Let's move on to the afterword.

Afterword

Something like this. About all sorts of deep settings and other tabs, within the framework of this article, I will not talk, since they are not particularly needed. The remaining tabs are responsible for overclocking, information and other useful data (more on that later).

As part of the next article from this series, I told in detail how to adjust the speed, because they have their own BIOS and a fan, powered not from the motherboard or PSU, but from the card itself, and therefore control them through speedfan or the motherboard will not work.

As always, if you have any questions, thoughts, additions, comments, and so on, then welcome to comment on this post.

Want to know how seriously to bask system unit(this is especially true in the summer) and reduce the noise of a computer that seems to be about to take off. Then you need to get into the BIOS, trying to wait desired settings, unless, of course, you are afraid to change something like that, but this is only suitable for advanced users, or everyone else tries to get by with the utilities that come on disks with motherboards, which theoretically allow you to control the operation of fans, although usually rather inefficiently. As always, there is a third way - third-party utilities that can work with most modern hardware. One of the popular utilities that allows you to take data from sensors motherboard, video cards, power supply and hard drives, as well as control the operation of fans is SpeedFan.

The installation of the utility proceeds according to the standard scenario, confirmation of the license agreement, dates of goodness for placing icons to launch the utility, select the folder where the files will be placed. Well, that's all, the program is completely ready to work.

SpeedFan collects all sorts of data about your computer, such as temperature, voltage, processor frequency and cooler speed, and allows you to theoretically (why you will learn later) adjust the operation of fans and change the frequency of the processor.

The utility interface looks unsightly, but it is simple and clear, where all the features are grouped into separate tabs, although some of them have very strange names:

- Indicators. Here we are given all the information about temperature, fan speed and voltage, but most importantly, it is from here that we limit the fan speed. We limit the turnover by changing the numbers in the points of the signed Pwm * (with previous versions were called Speed ​​*), setting how many percent it will work from top speed cooler.

Frequencies. Here you can change the frequency of the processor and system buses, but for ordinary users far from computers, I do not recommend turning or turning on anything here. If anyone is interested, first selects the manufacturer of the motherboard, then the clock frequency generator that is used (it is better not to select anything at random), only then we set at what frequency the processor will operate depending on the load on the system.

Information. For ordinary users, there is nothing interesting here. In fact, here they propose to read the data on the chipset used on the motherboard and send utilities to developers so that they can implement support for common hardware and sensors.

Exotic. Under such a strange name, a plate is hidden where all the parameters that the utility monitors are displayed, illustrating with arrows which values ​​​​are falling or rising.

— S.M.A.R.T. here we can check the status hard drives, where green circles mean everything is fine. If you see a yellow triangle, then the hard drive is in a pre-emergency state, and a red circle means that some of the parameters have gone beyond critical values, and data loss is only a matter of time. Select the desired hard drive from the top drop-down list.

Graphs. In this section, those who wish can get acquainted with the statistics of changes in temperature, fan speed and voltage in the form of graphs.

Now about some features of SpeedFan. To begin with, the utility does not always correctly determine temperatures, so for the experiment, you can first try alternative utilities and compare the results to make settings. Also, in order for the fan speed to be adjustable, they must be connected to the motherboard in a 3-pin connector. Although, again, not every motherboard allows you to adjust the fan speed.

The names of the fans look very sad, which only differ in digital indices and it is not clear which one is responsible for what. Although it all depends on the motherboard, some parts of the coolers bark meaningful names. You have to use cunning experiments to get to the bottom of the truth of how to stop with crayfish, drive in games and just watch how the speed changes after changing the parameters.

The settings can be accessed from the "Indicators" tab by clicking on the "Configuration" button and a lot of interesting things are hidden here, which will allow you to customize SpeedFan for yourself. Here you can disable unused or redundant sensors and fans, set the optimal and critical temperature for each sensor (for example, I had to raise it to 85 degrees for a video card), enable automatic adjustment of the fans, depending on the temperature of the sensors. For dessert, those who wish can write scripts that will be executed on certain events, launching programs, sending letters to email or by causing pop-up windows with warnings.

SpeedFan basically works, giving out a bunch of useful and not very information, allowing you to adjust the fan speed. But here's the right way to make it work is a whole art, where you first have to experiment to figure out the terms and climb the forums. Although, as the simplest option that does not require much effort, you can reduce the numbers in Pwm * on the main tab.

If you have a very noisy computer, straight arms and are ready to spend some free time, then you should install and properly configure SpeedFan.

Works great in 32 and 64 bit operating system. The program interface has been translated into several dozen languages, including Russian, although some phrases have remained in English.

Latest version at the time of writing SpeedFan 4.47

Program size: setup file 2.04 MB

Compatibility: Windows Vista, Windows 7 and Windows XP

SpeedFan is a program that monitors the state of your computer. The utility provides real-time data on cooler rotation speed, processor temperature, power supply voltage and other important parameters. Among other things, the program is able to identify current system problems, show graphs for various indicators, and also control the speed of rotation of all fans.

The main tab is "Indicators". It contains all the most important information on the system. For convenience, icons are used to warn of an increase or decrease in temperature. The fire icon characterizes a critical condition, however, many devices support operation at sufficiently high temperatures. Therefore, do not get scared prematurely, but it is better to look at the technical data sheet to find out the exact range. A little lower is the cooler rotation speed control unit.

A separate section is devoted to S.M.A.R.T technology for the selected hard drive. In fact, these are 2 types of tests - extended and short. After launching any of them, information about errors will appear in the status column, if any. To display the status of a particular attribute, there are 3 icons: green with the inscription "OK", yellow triangle with exclamation mark and a red stop sign with a white stripe. The first means that everything is fine with the attribute, the second - the attribute is close to the threshold value, the third - a critical case.

The default is English language. However, it can be changed to Russian through the "Indicators" tab → the "Configuration" button → "Options" → "Language". Please note that tooltips and some parameters and all attributes from the S.M.A.R.T section will remain in English. So, RPM stands for the number of revolutions per minute of your fan. But most of the text in the program was still Russified.

SpeedFan allows you to display important indicators of the health of your computer. However, the main function of this program is to monitor the cooling of the entire system and directly all available coolers. This utility will be very useful for the prevention of breakdowns when the iron overheats.
