Fan rotation speed regulator: types of device and connection rules
The fan is one of the inconspicuous, but extremely important devices that help create favorable conditions for work, relaxation and just a pleasant time of time.
HOW TO CONTROL ELECTRIC FAN USING DIMMER
Computers, refrigerators, air conditioners and other equipment will not be able to function without it. For the most efficient operation of various devices, a fan rotation speed regulator is used.
From our material you will learn about what regulators are, the features of their work. We will also tell you how to assemble a device with our own hands and what you need for this.
AMD video cards control using Catalyst
Actually, as far as I remember, unlike the “green” cards nvidia. AMD.Schnikov for some time (or perhaps for a long time, I don’t know for sure) there is a basic opportunity to adjust the steeple at the drivers level using the long.suffering Catalyst and the AMD Overdrive mode. The thing, as far as I know on my new video card, is generally working, but in general I never liked the bulkiness of the drivers and the accompanying Radeon ‘OV. However, I will squeeze on this subject later, but for now, briefly about how it turns on.
- We launch the AMD Catalyst Control Center (hereinafter the example is given on the basis of the driver of the drivers for February 25, 2014), twice setting the corresponding icon in the TEA (near the clock):
- At the top right, click in the “Parameters” button, where we select the “Expanded Presentation” item:
- In the menu on the left we find the item “performance” in which the subparagraph “AMD Overdrive” lives. There we put two checkmarks, one of which is called “Turn on Graphics Overdrive”, and the second “Turn on manual control of the fan”. I immediately warn that the second checkmark does not work without the first (in any case, it was at the time of writing the article).
- We set the desired amount of percent and click in the “apply” button in the button.
So everything is simple, as I said initially, and how, I think, many of you have known. precisely, conditionally simple. Why conditional? I am a rage, as promised. The fact is that nothing is so uncomfortable than this decision, it was difficult to come up with. At first, of course, it seems, they say, turned on and forgot, but in practice it turns out that after rebooting in some systems and cases, AMD forgets which window was opened by the last. This is treated, as a rule, removed on the main page with a box “display this page when starting”:
But not everywhere and does not always help, t.e. We have to climb into the settings again throughout the above path in order to switch the slider again to another position (for example, now I need not 20 percent, but 60). It is strongly incomprehensible to me why it was impossible to do as in Rivatuner. Namely, the ability to indicate the minimum number of speeds that suits me, and then set the minimum temperature, the maximum temperature, the operating temperature and the temperature range, based on which more than more than less speeds would have already been regulated. Well, or how it was done in the ATI Tray Tools (which now neither alive nor dead when communicating with most conditionally new lines of cards, and with some of the old ones it only works after dancing with DLL. tambourine and jumping):
Well, or at least, purely humanly, to make the control of revolutions in the tray, because the same pancakes, 3D settings were taken. which change 30 times less.
Generally. It’s a shame. Obvious things, it would seem, are not provided for nafig by anyone. I understand that many here can write, they say, why configure it all with your hands, let it work as it is, depending on the temperature according to the script provided by manufacturers. But there is a car and a small cart of the nuances that are associated with the volume of the cooler, temperature modes and a lot more, which is not related to the topic of the article under discussion, as well as what you are reading now 🙂
Something like that. I hope that this material will help the owner of Nvidia cards to configure the thin balance between the noise and the quality of cooling, which is extremely useful, pleasant and interestingly.
As always, if there are any questions, in particular individual and important, you can safely ask them in the Комментарии и мнения владельцев below.
Thanks for your attention and. stay with us 😉

Adjustment using Speedfan
Speedfan is the most popular free application with a Russian.speaking intese. Among its functions:
- Determining the degree of loading of the processor and each core.
- Temperature control of the main components PC.
- Monitoring of the working parameters of the system.
- Fan speed control.
The program allows you to adjust the speed of each fan connected to the motherboard, simultaneously evaluating how the temperature on the sensors changes. You can set the necessary levels of temperatures, and the system will automatically adjust the speed speed of coolers. You can also set automatic mode. To do this, put a box in the Automatic Fan Speed line (Auto.ski fan).
In most cases, if the fans are connected directly to the power supply, they can only be adjusted physically.
Details on various regulators in Speedfan
I say that there is something in the case of an indicator of the speed of rotation (measured in RPM. t.E in the number of revolutions per minute):
- Sysfan (FAN1) shows the speed of rotation of the steeple (I mean the fan), connected to the Sysfan nest on the mat.board. It can be either a cooler installed on a chipset, or any other, simply stuck in this connector (all connectors per mate.the board is signed accordingly);
- CPU0 fan (fan2) shows the speed of rotation of the steeple on the processor, t.e fan stuck in the CPU_FAN connector for mat.board;
- AUX0 FAN (FAN3) talks about the current rotation speed of the fan connected to the AUX0 connector;
- CPU1 fan (fan4) similarly CPU0. But only if you have a second processor or a cooler connector with the cpu1_fan mark;
- AUX1 FAN (FAN5) similarly AUX0, T.e shows the speed of rotation for the cooler stuck in the AUX1_FAN connector;
- Pwr FAN (FAN6) It happens that the speed of rotation of the cooler installed in the power supply (not always) is indicated here, or simply the speed of the fan that is stuck in the PWR_FAN connector on there.board.
Once again, I note that each parameter here corresponds to the match for matches.the board and almost any cooler can be stuck in any of it and then its indicator will be displayed in the corresponding column.
Naturally, that should be stuck through a small 3-pin.The connector in the mat.fee, not eating from a power supply. To make it clear, let’s show you a photo.
Methods for managing the cooling system
If modern PC have three fans (one on the processor, the second on the video card and the third for the built.in drive), then portable computers most often have one fan. With an increase in the strength of the fan in the laptop, you can increase the operation of either one cooling device or two.
There are two ways to adjust the power of the cooling device:
But whatever way to increase the speed of the cooling device you choose, you must first put in order a portable laptop. To do this, you need a laptop, clean the fan blades and all the elements of the motherboard, so that there is no dust. Since it worsens heat transfer, which leads to an increase in the temperature of the system. This can be done independently or seek help in specialized services.
Advise such a procedure to do once every 6 months.
Reduce the noise and turn of the cooler
This is my first post, in the following I will tell you how to make a video observation, a liquid cooling system, automated (programmable) lighting and a lot of tasty, we will solder, drill and flash chips, but for now we start with the simplest, but nevertheless, but nevertheless, but nevertheless we start with the simplest, but nevertheless. very effective reception: installation of a variable resistor.
The noise from the cooler depends on the number of revolutions, the shape of the blades, such as bearings and other things. The more revolutions, the more effective the cooling, and the more noise. Not always and not everywhere you need 1600 about. And if we lower them, then the temperature will rise by several degrees, which is not critical, and noise may disappear at all!
On modern motherboards, the control control of coolers that feed on it is integrated. In the bios, you can set the “reasonable” cut, which will change the speed of the coolers depending on the temperature of the cooled chipset. But on the old and budget boards there is no such option and what to do with other coolers, for example, the BP cooler or corps? To do this, you can mount a variable resistor into the cullar power chain, such systems are sold, but they cost incredible money, given that the cost of such a system is about 1.5. 2 dollars! Such a system is sold for 40:
You can make it yourself, using as a panel. a plug from your system unit (a plug into a basket where DVD/CD drives are inserted), and you will learn about this from this post.
Next, I will describe the process by the example of working with BP, but it is identical in all cases.
T.to. I broke out 1 blade from the cooler on the BP, I bought a new one on ball bearings, it is much quieter than usual:
Now you need to find a wire with power, in the gap of which we mount the resistor. This cooler has 3 wires: black (GND), red (12V) and yellow (tachometric contact).
Now we need a variable resistor with a resistance of 100-300 Ohms and a 2-5 W power. My cooler is designed for 0.18 A and 1.7 W. If the resistor is designed for lower power than the power in the circuit, then it will bask and in the end. he will burn. As suggests, Exdeniz, for our purposes, PPB-3A 3W 220 Ohms is perfect for our purposes. Such as my variable resistor, 3 contacts. I will not go into details, just solder 1 wire to average contact and one extreme, and the second to the remaining extreme (you can find out the details using the multimeter \ ohmmeter. Thank you Guessss_who for the comment).
Now we mount the fan into the case and find a suitable place for fastening the resistor.
The resistor has a nut for attaching to the plane. Please note that the body is metal and can close the resistor contacts and it will not work, so cut the insulator from plastic or cardboard. My contacts do not close, fortunately, so there are no gaskets in the photo.
Now the most important thing is the field test.
I turned on the system, opened the BP body and found the hottest section with a pyrometer (this is an element, it seems like a transistor that is cooled by a radiator). Then he closed, twisted the resistor for maximum speed and waited for 20-30 minutes the element heated to 26.3 ° C.
Then he put the resistor half, noise no longer heard, I waited for 30 minutes again the element heated to 26.7 ° C.
Again, I lower the momentum to a minimum (~ 100 Ohms), I wait 30 minutes, I can’t hear any noise from the cooler at all The element was heated to 28.1 ° C.
I do not know what kind of element it is and what is its operating temperature, but I think that it will withstand more degrees 5-10. But if you consider that there was no noise resistor on the “half”, then we do not need anything else! =)
Now you can make such a panel as I brought at the beginning of the article and it will cost you a penny.
UPD: Thanks to the gentlemen from the Комментарии и мнения владельцев, for the reminder of the watts. UPD: If you are interested in the topic and you know what a soldering iron is, then you can easily assemble an analog reoobas. As Fleshy tells us, the article analog Reoobas describes this wonderful device. Even if you have never sold boards, you can collect Roobas. The article has a lot of text, which I do not understand, but the main thing: composition, scheme, motive (This paragraph has links to all the necessary ration articles).
Conclusions and useful videos
How to connect a regulator to a fan. The example shows a thyristor controller, but the connection principle will help to understand the algorithm for working with a step device:
Features of connecting the canal fan through the speed regulator, two more methods are considered in the next video:
Step adjustment of the fan velocity makes the system less energy.consuming, more quiet, precisely controlled. The controller ensures the safety of the main equipment, increases its service life. This is facilitated by safe start, protection against closing, current loading, overvoltage, and non.completion mode.
The costs of acquiring a device are paid off by saving funds to pay for the consumed energy. It is only important to choose the parameters of the regulator for the served fan. Most manufacturers have tables of compliance of models that can be used with an independent purchase. Does not place a consultation with the store manager.

Management of the culer of the video card
To control the speed of rotation of the quilting coolers, you can use the appropriate tool drive tool or a third.party program specializing in this. We are interested in the latter, t.to. They are usually not tied to video cards of a particular manufacturer (although there are such). The most famous utility from this category is MSI AFTERBurner. We will work with her.
- We launch the MSI AFTERBurner program on behalf of the administrator.
- The adjustment tools we need are the lower left corner in the “fan” unit. By default, the option of automatic control of the fan rotation speed operates in automatic mode. Therefore, first of all, it needs to be switched to manual control mode, for which you need to squeeze two buttons. “cars” (the one with the letter “a”) and “determined by the user” (with the image of a man):
- Immediately after this, the Fan Speed slider is unlocked, which is located above the buttons. Moving it back and forth, you can set the required speed of rotation of the culer of the video card as a percentage.
how to repair fan regulator very easy at home
As in the case of Speedfan, in MSI AFTERBurner, you can also automate the control function of rotation of the cooler from the video card. This is the same as leaving the “Auto” button, only the user sets the fan rotation speed when the video card is heated to a certain temperature.
