Proper installation of fans in the system unit

The principles of installation of the fan for the case

Cooling fan: which side to put, in which direction it is blowing, spinning or rotating. Basic rules for the correct installation.

It is very important to install the fan correctly. It will be necessary to determine which side to properly put a fan for effective ventilation of the components of your computer. If you put the fan, you can completely lose ventilation.

Inside the closed system unit, the air moves in front from the bottom in the direction upwards. Any fan inside the computer must strengthen this movement. At the same time, cool air is more intensively entering the block, and hot is blown out faster.

To minimize the errors that occur during the installation of the fan, some manufacturers indicate which side to put the fan. This is usually indicated by arrows showing the direction of movement of the created air flow.

What are the fans inside the computer?

As mentioned above, during long.term work, the elements of the computer can heat up. Most of all. the central processor, motherboard, GPU (graphic processor). Air cooling is usually used to reduce their temperature. Fan, it is also called the cooler, blowing hot air, which is assembled around hot elements. Cooling by creating air flow is the most practical and inexpensive option. Heating parts can additionally be equipped with radiators (heat heaters). The more powerful the computer, the more it needs to cool.

Having removed the nameplate and the plug from the cooler during the analysis of the computer, you can see the following components:

  • a bronnote engine that functions from direct current;
  • rotor;
  • the impeller fixed on the plastic basis of the rotor;
  • a magnet of an entire.metal structure;
  • Copper coil from magnetic circuits at the stature.

The rotation of the cooler shaft occurs when the rated voltage is supplied to 12V.

Friends, whether I arranged the coolers in PC correctly?

I have the Lian Li O11 Air case, and on the example of its official photo I will show the location of the coolers in my PC.

Below are 2 pcs. AEROCOOL REV 120mm cooers that are marked with red dots and serve air.

To the right side relative to the front is blown by one Aercool Rev 120mm which is also marked with a red dot.

On top almost even straight indicates 3x sectional dropsy, which blows air up from the processor.

I have a fairly hot PC therefore the location of the coolers probably plays a role:

AMD Ryzen 7 5800X GTX 1080 Ti from the hottest.

Correctly. In the Patsansky PC, coolers must suck dust from the floor so that the boy should not vacuum)

Correctly. In PC, the curls must be blown out of PC, so that you can vacuum it later)

Please advance this comment in the top. A person at least normally put cooling

As I understand it, I noted the reds where I installed and went out. Herobosta, to be honest. The air space for blowing is small, it will suck out the whole garbage that settles and generally makes a stream for blowing ineffective. I understand that the MB proceeded from the logic that the hot air rises, but. You have a cold stream limited, the video card overlaps part of the flow to the components, and you are not blowing into the vidyuhi grate, but in its design corps for the most part. T.e. You do not stupidly blow up most PC due to the fact that the video card overlaps them already controversial flow. I am silent about the general behavior of cold and hot air, so as not to breed holivar.

CRC drew like normal guys usually stands. Logic to madness simple.

Now the upper turntables, on the contrary, have gained relevance, the video cards are powerful, the flow, respectively (for example, I tell you 3080), you can heat up directly on cold days from the turntables from above, if the card is 100%, I can’t imagine what it would be without them.

Absolutely agree. Without a video card and describing her cooling system, an empty conversation. BP is not yet in the scheme, it also pumps air, but since it is not, it is not clear where.

Those that are not only useless from below almost in terms of cooling, but the dust will also absorb perfectly

They need them to throw a couple of degrees from Vidyuha, if there are filters no dust

Put the radiator upward, two/three on the muzzle on the blowing and one behind.

You can immediately hide to “positive pressure”

I never understood the jokes to set the dropsy up, the radiator sucks hot air from the video card and VRM. Dotted by blowing must be put in front (or from the side, if the open case is TT Core P3)

so that passing the air through itself, at the exit the hot falls inside the body?

Working principle of Fan Coil Unit

To the right side relative to the front is blown by one Aercool Rev 120mm which is also marked with a red dot.

No need to blow it there. Where did the hot air come from, what to blow? If you rearrange it on a blowing, then at least a tributary of some kind will be a tributary in the upper slot.

He leaned from this flashback from the 90s. Okay then, but in now? This size is absolutely useless, even in so much. I still moved from the end to 200mm fans. They are inaudible, more slowly than small ones, but pump many times more air and do it more silently.

There should be more fans by blowing than blowing, so that there is excessive pressure in the housing. Applies to buildings with dust filters. Or an equal amount on the blowing/blowing. Rearrange the one on the side wall so that it works for a blowing. And better put him on the front side so that it blew respectively in blue shooters in the scheme. And put the lower right in the center so that it was blowing in vidyuhu and not by) or all three down. Note: on blowing you already have 3 fans on a dropsy.

Please, please explain in more detail why? For example, I have three, for blowing one. In the case, discharged air, the air from the room there itself is sucked, the system strives for equilibrium. The temperatures are normal: the percentage in the load is no more than 70, the vidaha is more than 80

The tests show that 2-3 fans (from the bottom up) are enough for the blowing and the 1st back on the blow. Everything else practically does not affect cooling. Holes from above and below are needed for passive air output. Active only breaks the flow. https: // www.YouTube.COM/Watch?V = Y842HNBL4QC

So do it. Leave 2 from above. BP stands from below? Right under it there is a hole for a separate fan?

As practice has shown, if the case is normal, then three turntables are saved (two 140 mm on the face, one 140 mm on the ass) in the summer heat 45.

On the muzzle 3 add.up and three below the cooler do not make sense well, and from above why why? If not heat in the summer. if there is dropsy, then on the side, as in the figure is shown everywhere and everything is set so, but if there is no dropsy, it is better not to clog it with the culers superfluous and so blowing in front and behind the classic.

technically correctly, but the main thing is that the influx of “fresh” air is. For example, I have a systematic system below (on special. stand for the computer. table), from below to “suck” him from nowhere, back and side of the heating battery. Side cover. fecal glass (add. You won’t insert the fan). At the time of high loading, the video card heats up to 82 degrees. but if the condo is turned on for cooling and the door is closed, the topics inside are reduced by 10 degrees!

I have approximately the same: lower, front, side. Buying, upper, rear. blowing. only 8 turntables, 5/3. Logically, cold air drives a warm upstairs.

It’s unclear. Below the left is the red point, and where the power supply is installed? Proceded by water or air? It is important. If air, then there should be more bluntly than to blow in otherwise the vidaha will be fried specifically. Put one on the bottom from the bottom, but you can do it without it because of the dust, it will reduce a degree for Vidyakha, even the 120th will come down. There are two 140s on the front in the front, by blowing one 140 on the rear and you can put three 140 boldly on top of it. Everything is hard to calculate, t.to. BIOS controls each cooler separately or a group of coils. Well, I set up everything separately according to the scheme as described above, but I have dropsy on the pro.prick. Horn Stricks 3080ti above 75 degrees did not see.

Location on the back wall

The fan installed behind should work on blowing, that is, remove warm air outward. At the same time, the warm air flow no longer goes through the power supply and does not cause it overheating. In addition, the cooling of the processor improves. This option has a disadvantage. in the housing, a sparse is created, and the flow of air through all kinds of holes in the body brings with it a lot of dust. However, the use of such a scheme still significantly improves the situation.

Typical air cooling for a computer

The most common and cheap cooling system used in computers is air, which works using special fans. For a better heat removal and an increase in the heat supply surface, metal radiators are placed on the most important parts. They take a lot of heat, but their area is limited, therefore fans are additionally used. For example, he is on the main processor, in addition to the radiator, as this is one of the most important and hottest chips. For the best effect, at least one additional cooler should be installed in the system unit, which will create constant circulation of the air and remove hot outside. 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 in the upper part of the computer. Warm air, rising up from the motherboard and additional devices, with it is blown out. But this design has disadvantages:

  • All warm air goes through a power supply, which itself is not weakly warming, which is why its details overheat even faster. Therefore, it fails most often.
  • A reduced pressure is created in the computer’s body, and for aligning, its air enters from where it came from nowhere. through all the cracks. Therefore, a lot of dust quickly accumulates inside, even more worsening heat.
  • The stream created is not particularly stable, again, due to the influx of it from all possible holes. Unnecessary and harmful turbuilders are created, greatly reducing the effectiveness of the entire system.
  • The air flow is not very strong, for low devices, for example, a video card, clearly insufficient.

Therefore, the installation of additional coolers in the system unit is required. They are inexpensive and you can put them yourself.

How to correctly install a tower radiator on a processor

Almost all modern air cooling models for processors are tower radiators (in the photo). Other models with direct blowing towards the motherboard are used only on very weak CP models. Any more or less powerful processor requires a tower radiator.

To begin with, you need to pull out the motherboard from the case and turn off all the devices from it, remove all the modules (RAM, SSD, etc.D.).

Disconnect the cooler of the existing cooling and then the instructions will be slightly different for Intel and AMD processors.

Remove the old radiator, disconnecting the fast.removable bracket. This can be done by turning, eccentric clamp. Next, you need to remove thermal grease and apply a new one (the technology is described above). As a result, thermal paste should only fill the microcracks, and not be a layer between two metal surfaces. Please note that the thermal paste has already been applied to many radiators from the plant, in this case you do not need to apply a new one.

How to Install a Case Fan in your PC

The usual cooler is attached with the same clip with an eccentric or hook. Just install it in place and clamp it with a quick.detachable mechanism.

Then you need to connect the fan to the motherboard through the 4th PIN connector and on this the installation of a radiator of the tower type is completed.


You can remove the old radiator if you turn counterclockwise fast.fastenced mounts with latches. Next is the cleaning of the old thermal paste and applying a new.

To the new cooler you need to fasten fasteners with leg legs. Screw them from below, otherwise the legs will not reach the motherboard.

After you equipped the new radiator with mounts, you need to put it in place of the old, snap plastic legs in the landing nests and turn the lock clockwise.

Connect the cooler to the motherboard and the case is done, nothing needs to be tuned.

A little about the main thing

It will not be a secret for anyone that all components of a personal computer tend to heat up. Some of these elements are very strong. CPU, GPU and motherboard. the most heating details inside the system unit. That is why each user must take care of proper cooling and high.quality removal of heat flows.

Most often, computers use air cooling, since it is very practical and cheap. The principle of operation of such a mechanism is very simple: the elements give heat to the air around it, and the hot air is blown out of the body of the system unit using fans. Also, quite often PC details are supplied with heat-voltage elements (radiators).

Important! So that the computer is less heated during operation, it will not be superfluous to buy an additional special stand for the laptop.

The importance of the cooling system is simply obvious, but how to correctly install the cooler on the processor and other components of the device?

Common errors when installing coolers

Before you put the cooler, read the typical errors that users make:

  • The back fan works for a blowing, front to blow. Warm air that will rise from the power supply enters the housing. Cooling in this case insufficient.
  • Only a back fan is used, which works for a blowing. The same as in the previous case, plus excess pressure is created inside the chassis. Air circulation is disturbed and the details are overheated.
  • Only a back or front cooler is used, working on blowing. Low pressure is created inside the case. Dust penetrates through all possible cracks, as a result of which the “insides” of the systems are clogged much faster.
  • The front propeller works for a bite, the back is missing. Excessive pressure inside the computer does not allow the details to cool normally.

Temperature monitoring

If you are not sure whether the case is cooled from the inside with the scheme you collected, you can use special software. for example, Sisoftware Sandra Lite or EVEREST.

Recommended average temperature values:

  • Processor. up to 90 degrees;
  • Power supply. up to 50 degrees;
  • The video card is 50.70 degrees;
  • Chipset on the motherboard. up to 60 degrees;
  • Hard disk. 30. 40 degrees.

It is also important exactly where the computer is located. If it stands on the desktop, then usually there are no problems with cooling. It is usually placed in a special compartment in a computer table. Check if the walls interfere with the normal movement of air inside the case.Dust is a good heat insulator. You need to open the body at least once every 3 months and clean the “insides” of the computer. You can use a vacuum cleaner with a plastic nozzle that works on blowing.

Be extremely careful when using a metal nozzle. A breakdown of sparks may happen and provoke a short circuit, which entails a failure of some components.
