Where the air must blow in the power supply?

Most of the power supply fans are absorbed by the air from the inside of the case and produce it through the back of the housing. As for the fact that more importantly, as a rule, you want to have a small positive stream so that the dust does not get into your car. This means that consumption will be slightly more than exhaust.

If the air intake is blocked, it will heat the power supply, which will lead to its failure. A more secure approach. install the power supply in the fan up. Single rear exhaust fan will blow hot air beyond the housing. The power supply fan also helps suck hot air from the inside of the case and blow it back.

Typical air cooling for computer

The most common and cheapening cooling system used in computers is air, which works with special fans. For better heat removal and increasing the heat sink surface to the most important details put metal radiators. They take a lot of heat, but their area is limited, so fans are additionally used. For example, it is on the main processor, in addition to the radiator, as this is one of the most important and hottest chips. For a better effect in the system unit, at least one additional cooler must be installed, which will create a permanent circulation of air and output hot. In most computers, especially in the minimum configuration. the so-called office version, no additional cooling is installed. However, in such models, there is still one cooler. in the power supply, which is located at the top of the computer. Warm air, rising up from the motherboard and additional devices, is blowing out with it. But this design has drawbacks:

  • All warm air goes through the power supply, which does not warmly warm, why its parts are overheated even faster. So he fails most often.
  • In the computer case, reduced pressure is created, and it comes inside to align it inwards. through all the cracks. Therefore, a lot of dust accumulates inside quickly, even more deteriorating heat dissipation.
  • The flowable stream is not particularly stable, again, due to the tributary of it from all possible holes. Created unnecessary and harmful swirls, strongly reduce the effectiveness of the entire system.
  • The air flow is not very strong, for low devices, for example, video cards, clearly insufficient.

Therefore, the installation of additional coolers in the system unit is required. They cost inexpensively and you can put them on your own.

Installation of additional fans.

Let’s look at the main points of the correct installation of cabinet fans for most system blocks. Here we give advice for standard buildings, since the non-standard location of the fans is so diverse that it does not make sense to describe them. all individually. over, non-standard enclosures of fans can reach 30cm in diameter.

There are no additional fans in the housing.

This is a standard layout for virtually all computers sold in stores. All hot air rises into the top of the computer and at the expense of the fan in the power supply, it turns out.

A large disadvantage of this type of cooling is that all heated air passes through the power supply, heating it even stronger. And therefore, it is the power supply that such computers breaks most often. Also, all cold air is absorbed not controlled, but from all the enclosures, which only reduces heat exchange efficiency. Another disadvantage is the affixiness of air obtained with this type of cooling, which leads to the accumulation of dust inside the case. But still, it is in any case better than incorrect installation of additional fans.

One fan on the back of the housing.

This method is used more from hopelessness, as there is only one place in the case to install an additional cooler. on the rear wall under the power supply. In order to reduce the amount of hot air passing through the power supply, one fan is installed on the “blowing” from the housing.

Most of the heated air from the motherboard, processor, video cards, hard disks come out through the additional fan. And the power supply at the same time heats up significantly less. Also, the total flow of moving air increases. But the rustling increases, so the dust will accumulate even stronger.

Additional frontal fan in the case.

When there is only one seat on the facial part of the case, or there is no possibility of including two fans at once (I have nowhere to connect), then this is the most perfect option for you. It is necessary to put on “blowing” one fan on the front of the housing.

Fan need to be installed opposite hard drives. And it will be more correct to write that the hard drives must be put opposite the fan. So cold incoming air will immediately blow them. This installation is much more efficient than the previous one. Created directional air flow. Decreases the vacuum inside the computer. the dust is not delayed. When feeding additional coolers from the motherboard, the overall noise is reduced, as the fan turns are reduced.

Installing two fans in the housing.

The most efficient method of installing fans for additional cooling of the system unit. The fan is installed on the front wall of the case, and on the back wall. to “blow out”:

Created a powerful permanent air and directional stream. The power supply works without overheating, as the heated air is outputting the fan installed under it. If the power supply is installed with adjustable fan rotation turnover, the general noise will noticeably decrease, and that more importantly, the pressure inside the housing is aligned. Dust will not settle.

How to put a fan on blowing or blowing out and what is more efficient?

Hello, dear visitors to my blog! Today we will discuss how best to put a fan: on blowing or blowing and why. Also, in which case, the cooling system works more efficiently and how to understand where the cooler blows.

About how much fans it is necessary to have in the system unit housing, you can read in this post.

If you observe the work of PC, you can see that on the processor and on the case of the impeller rotate to blow. This is not by chance: the main task of the cooling air system is primarily due to the discharge of excess warm air, and only if possible, it is necessary to ensure the flow of cold.

It doesn’t matter if on top on the case you put additional impellers or bottom. the principles that I will describe further, are valid for any layout.

So, if the cooler works on blowing, it creates a chassis cut. Heated air is pushed out from there with an impeller, and the new is absorbed due to the pressure drop through the technological holes. It is noted that in this case there are no obstacles to continuous air circulation, and there will be no cooling problems.

With such a layout on blowing, you need to put an impeller on the back cover of the case.

If the cooler works on blowing and no blowing fan, an overpressure of air is created in the housing, which prevents its normal circulation and is fraught with overheating of PC components. In addition, a lot of dust will be absorbed, so the “insides” of the PC will often have to clean.

Ideally, it is best to install 2 coolers: blowing on the back cover and on the suction on the front panel. If there is no such possibility, put one on blowing on the back cover of the case.

Easiest to connect coolers to the power supply or motherboard and see how it works. Naturally, before finding out this, you need to remove the side cover to access all power connector.

And there is another way to understand where the main flow goes. where there is a sticker with a model or name, there will be a blowing propellers.

How can I install fans in the computer case

Installing coolers in the system unit is done in various schemes. Before working with them, it is necessary to familiarize yourself, because the incorrect placement of these nodes can bring even more harm than their absence. Usually on the motherboard there is a pair of connectors for cooled. They can be used both either only one. Fan installation schemes in the computer case will then be such:

You can choose any of these options, but the most desirable. the last. Note that the introduction of only the 1st cooler is either differently violates the air balance in a closed system. Therefore, we will see each option separately.

Step-by-step instructions and masters tips

The most important details of the system are usually the hottest. Therefore, that the work of the entire system is not at risk, it is necessary to take care of cooling. This article will talk about how to put a cooler for the processor.

Cooling options

The processor is one of the most stronger parts of the system unit, and if it is not cooling it, it will burn in a matter of minutes. The cooler for the system unit is placed right on it. Cooling is different, depending on how powerful processor is installed in the system.

There are two types of cooling. it is active and passive.

Passive cooling lies in the fact that it is represented as a simple radiator reducing heat from the processor. This type of cooling does not require much energy and is cheap, and also does not make such noise like fans.

Active type of cooling involves the presence of a fan next to the radiator. Sometimes in such coolers there is a marking of the direction of air flow, which makes it possible to decide which way to put a cooler on the processor.

Composition of cooling system

The composition of the cooling system includes two components. this is a fan and radiator. Copper or aluminum tubes remove heat from the processor, towards radiators, and radiators are cooled with a fan or fans. Noise from them, of course, there is, but within the limits permissible.

Mounting a cooler on the AMD processor

First you need to make sure that the processor is securely fixed in socket. Next, it is necessary to clean the processor and the radiator at the place of contact so that the contact between them was not broken. For these purposes, a disposable alcohol napkin is ideal, as it does not contain a pile and provides full purity after.

blow

The next step is how to put a cooler on the AMD processor, will apply the thermal paste. This procedure is necessary because the thermal paste provides complete contact of the processor with the radiator, which significantly improves the heat sink. It is not necessary to damage the paste, it is enough to smear it to such an extent that the outline of marking on the processor.

Manufacturers who make cooling for AMD processors try to adhere to one standard in which a simple latch is used to fix the cooler on the processor. After the cooler was fixed, you need to connect it to the motherboard.

Installation of the cooler on the Intel processor

First, it is worth considering the cooling options before put the cooler on the Intel processor. Mounted cooler only on the motherboard in a horizontal position. Also do not forget about the reinforcement plate, which is included.

Complete with some processors already have a cooler, which is called boxing. The cooler of this type does not require special installation knowledge. It is necessary to find holes on the motherboard, choose the right position and insert pins into connectors. After installation, the characteristic sound of fixing should appear in each pin. The last action will be the connection of the cooler to the motherboard.

In modern advanced systems there are no less advanced processors. Such processors require a high-quality cooling system, and further will be instructions on how to put a cooler for the processor. This time presented the installation of the tower cooler.

To begin with, it is necessary to unpack and collect the cooler according to the management. Sometimes cooling system is sold already in the assembled form, then this step disappears.

A small amount of thermal paste must be applied to the installed processor. It is not necessary to smear it, since the paste will evenly distribute when the cooler.

To secure the foundation on the motherboard, it is better to look at the manual, as different models can be attached differently.

As in many models of coolers, there should be an image on the fans indicating the direction of the blades. These markers will help to decide which way to put a cooler on the processor so that the air flow is directed to the rear wall of the case.

Dismantling system cooling

After the options were presented to put the cooler on the processor of different manufacturers, you can figure it out how to remove it.

First of all, it is worth turning off the power of the cooler, and then unscrew the bolts. If the fan is fixed with the latch, you can simply pull out the fan, moving the fixing part.

In case the cooler is poorly dismantled, it means that the thermal paste inside. To get rid of it, you need to warm up a problem. In this case, the usual hairdryer copes well.

Errors and advice

Before dealing with how to put a cooler on the processor, you need to choose it. Many users, inexperienced parts of computer spare parts, allow many errors that will be presented below.

blow

The first thing to find out before buying a new cooling system is a socket that supports the processor. The fact is that the radiator must tightly and accurately lay down to the processor, otherwise cooling will not be so effective.

Next, it is worth dealing with energy consumed, since the more power consumption in the processor, the more powerful the cooler.

Do not save when it comes to cooling, since it depends on the life of not only the processor, but also the entire system.

Commission shops and purchases “from hand” no one canceled, so before purchasing a cooler, used to be tested in place and check the package.

How can I control the speed of the fan of my power supply?

Most likely, there is no way to control the speed / fan noise in your power supply. Most likely, it is built into the power supply and, possibly, at best, sensitive to temperature. (Some models have external fan controllers, like me) the only thing you can do is change it to another fan.

And only in rare cases you can see the fire or even a little smoke. Thus, we come to the conclusion that no program or virus can never force the computer to explode, and only in rare cases can make the computer warm up or make it light up and make melting chip.

How to install fans in the computer case

The computer device is quite complicated. it consists of a variety of blocks, each of which highlights a lot of heat. Overheating of any of them can lead to improper operation and emergency shutdown of the computer, at worst. to failure. The processor, video card, the chip of the Northern and South Bridge on the motherboard are especially heated. But other nodes also heat. for example, the hard drive with active work heats up very significantly. So the computer needs cooling.

Warm air, rising up from the motherboard and additional devices, is blowing out with it. But this design has drawbacks:

How can I install fans in the computer case

The installation of coolers in the system unit is made by different schemes. Before you start working with them, it is necessary to get acquainted, since the improper location of these nodes can bring even more harm than their absence. Usually on the motherboard there are a pair of connectors for cooling. They can be used both or only one. Fan installation schemes in the computer case will then be such:

  • On the back wall at the top, opposite the processor.
  • On the front wall.
  • Using two fans. front and rear. This is a combination of the first two options.

You can choose any of these options, but the most preferred is the last. Note that using only one cooler somehow disrupts the air balance in the closed system. Therefore, consider each option separately.

Rear wall

Fan installed behind the fan should work on blowing, that is, to output warm air out. In this case, the warm air flow no longer goes through the power supply and does not cause it overheating. In addition, the processor cooling improves. This option has a disadvantage. rareness is created in the housing, and air flow through all sorts of holes in the case brings with you a lot of dust. However, the use of such a scheme still significantly improves the situation.

Arrangement on the front wall

This fan must be located at the bottom, preferably opposite the hard drive, and work on blowing. It not only directly cools the hard drive, but also contributes to the leveling of pressure inside the case. The stream naturally goes from below-up, having flimple all important nodes and heated blows out from above.

Double option

Installing a pair of fans into a computer case. the best option. One of them should stand under the power supply on the back of the wall and work on blowing. The second is the front, installed on the front wall, and works on blowing. This is the most correct location of the coolers in the system unit, as it creates a good air flow by all nodes. Big plus. the balance of internal pressure does not allow to accumulate dust inside the case. But everything will work perfectly only when complying with the rules:

  • The size of the fans is better to choose the maximum for the installation site. if you can install a 140-millimeter model there, then put it, otherwise stop at a 120mm variant.
  • Need to control where the fan should blow in the computer case. Front. on blowing, rear. on blowing. Otherwise, the internal pressure and circulation of air will be broken, and as a result there will be more harm than good.

Basic errors when installing cooling

It is important to know how to put the coolers in the system unit. Incorrectly operating cooling system may be ineffective, or, on the contrary, create conditions for rapid overheating. The most important thing here is which way the cabin cooler blows.

  • Only the rear fan operating on “blowing”. At the same time, the warm air exit from the power supply is immediately served inside and moves along the same circle. At the bottom of the circulation body is not created at all, and everything heats up there.
  • Only the front fan is installed, which runs on “blowing”. So there will be reduced pressure in the case, and a lot of dust will be accumulated quickly. Heat removal will not happen, so everything will overheat, and the computer will constantly keep coolers on maximum speed, so also noise will be much more.
  • Rear cooler blows air, and the front. blows out. It is abnormally at least because warm air rises up and its stream can not be effectively directed down. Therefore, the effect will be the same as in the previous paragraph.
  • Both coolers are blown inside. In the housing, excessive pressure is created, the fans are working on wear, and the benefits naturally no.
  • Both coolers blow out. This is the most dangerous situation, since low pressure is created in the housing, air circulation is disturbed, and all computer components are very quickly overheated.
