Which side to put a cooler in the system unit?

As you can see, it is very important which side of the cooler. It’s worth turning it over, and he will start blowing not in the other side. Therefore, it should always be checked. The correct installation of the fans into the PC housing is the top rear must blow air, and the lower front is to blow.

The fan must be positioned on the front part of the PC case, but put on the “blowing”. It is necessary to place the item so that it is in front of the hard drive (s), since all cold air, which enters the device, will blow them.

Why need to change the fan

Usually, in low-cost dietary blocks, the fans are faced, which you won’t call. Manufacturers in order to reduce the cost of their products, including BP, consider it necessary to save everywhere and everywhere. At all without exception. And on the quality of the fan. too. They choose the cheapest, which, as a rule, is source of increased noise.

In many BP, the revolutions adjustment is carried out on a two-wire connection when the power supply voltage varies on the second wire, which is usually red.

It will be appropriate to recall the well-known rule. The larger the load on the BP, the faster the fan will spin. All logical. After all, if the device is experiencing a greater load, the components are more heated more.

In low-cost BP usually turnover is not entirely correct. It is programmed in such a way that the turnover is excessively large. And it does not depend on the load or heating. By the way, management may not be at all. And the fan as soon as it connects, spinning at maximum turns.

Of course, the size fan is 120 mm, which rotates on high speed (1800-2400 RPM), very well blows all that inside the power supply. However, noise is a lot. But manufacturers of cheap BP convince us that no need to give the noise of noise.

IMPORTANT! It is possible to achieve noise reduction only by reducing fan speed to an acceptable level. You can do differently: just replace the fan to one that creates less noise.

How to install a fan to blow?

The minimum required number of fans in the Tower-enclosure. two, naturally, one “Carlson” is better to install on the front panel on blowing, the second. on blowing out.

How to organize cooling in the game computer

Application of even the most effective coolers may be useless if the air ventilation system is poorly thought out in the computer case. Consequently, the correct installation of fans and components is a mandatory requirement when assembling the system unit. We explore this issue on the example of one productive gaming PC

This article is a continuation of a series of familiarization materials on the assembly of system blocks. If you remember, last year a step-by-step instruction “How to Collect Computer” came out, in which all the main points for creating and verifying PC are described in detail. However, as often happens, the nuances play an important role when assembling a system unit. In particular, the correct installation of fans in the housing will increase the efficiency of all cooling systems, and also reduce the heating of the main components of the computer. It is this question that is reviewed in the article further.

I warn you immediately that the experiment was conducted on the basis of one typical assembly using the ATX motherboard and MIDI-Tower form factor housing. The option presented in the article is considered the most common, although we all know well that computers are different, and therefore systems with the same level of speed can be collected by dozens (if not hundreds) of various methods. That is why the results are relevant exclusively for the configuration considered. Judge: computer buildings Even within one form factor have different volume and number of seats for the installation of fans, and video cards Even using the same GPU are assembled on printed circuit boards of different lengths and equipped with coolers with different numbers of heating tubes and fans. And yet certain conclusions are our small experiment to do well.

On the Internet you can find a large number of articles about the organization of cooling in the system unit, but many of them are written in those distant times when standard (typical, classical and so on) were considered computers with the upper power supply and a large number of baskets for 3.5- and 5,25-inch devices. Well, recently the standards have changed noticeably. This fact is clearly shown in the article “The computer you could collect, but regretted money. the best buildings, BP and cooling of 2017”. Trends if I don’t confuse anything, on the transformation of standard Tower-buildings began to be traced back in 2014, but now they have become a massive phenomenon.

So, a computer case with a landing place for the installation of a power supply at the top in 2018, you can safely call the wonder. Typically, such devices are located in the price range up to 2,000. In most other Tower-enclosures, the PSU is attached to the bottom, moreover, it is recently hiding it at all for the decorative damper. There, under the improvised curtain, sometimes put a basket for hard drives. For example, in the last five reviews, at the time of writing a article on our site, precisely such models were considered.

In my opinion, first of all, the manufacturers of the housings come in this way on the basis of aesthetic considerations, because the use of the battery hiding the power supply, unused wires and HDD, if there is a window on the side wall makes the system noticeably pretty. In addition, in the PC with such a case, you can safely install a non-module power supply, since unused cables will not affect the appearance. And the curtain clearly separates the power supply from the rest of the components, which, in turn, is well affected on its cooling. As you can see, we are seeing solid advantages.

The size of the Tower-enclosures has changed randomly lately, however, undoubtedly, the internal “restructuring” was provoked including the change of user priorities. People practically do not use optical drives, and therefore there is no need for 5.25-inch compartments in the case. Compact solid-state drives are increasingly installed in the system blocks. SSD form factor M.2 do not need any baskets. Taking into account the great popularity of online services and cloud storage facilities, there is no need to install a large number of hard drives in the PC, so one or two hard drives can well be fixed on the barrier wall of the case. Finally, more and more iron producers produce bright, spectacular components with illumination. This trend may not like, it can clarify and annoy, but more and more manufacturers of buildings produce more and more original colorful models with a side wall window.

All the design features listed above the new “classics” allowed, firstly, neatly lay the wires and loops, which contributes to the best air circulation inside the case and a smaller accumulation of dust. Secondly, the lack of baskets for 3.5- and 5.25-inch devices increases the free space inside the case. For the same reason, we can establish a larger number of fans that will work more efficiently. Actually, this is what is observed in modern devices, because even in mini-tower form factor housings, which support the installation of only mini-ITX-motherboards, can be fixed on the front panel at least two 120 mm fan. MIDI-Tower and Full-Tower enclosures allow you to install three, sometimes four fans on the front panel and as much. on the top wall.

How to determine the fan on blowing and blowing?

How to determine which sides blowing / blowing? On the side of the frame there is a marking direction of air movement arrow. If there is no labeling, then you can determine the shape of the blades. From the side where they are concave, the air blows away.

If the device is revealed, then the blades are laminated in the direction down. Movement occurs counterclockwise. Cases of today’s cooling computer elements have arrows, which depict the rotational direction and direction of the air flow. Any aggregate has two arrows.

Measuring seats under fans

After you have decided on the size of the fans, you need to choose their correct size. The fact is that the size of the cooler affects its performance and the noise level that it produces. The more cooler, the more air he can pass through himself per unit of time and the quieter it works. Therefore, it is not necessary to save and always need to install the biggest coolers from those that are placed in the case of your computer.

stand, power, supply

It is important to understand that different corps are designed to use coolers of different sizes. over, different places for installation can be designed for different size. For example, on the front side of the case there may be seats in size 140 × 140 mm, and on the back side of the housing 120 × 120 mm or vice versa. Therefore, before buying, you need to change the seats and determine the size of the coolers that you need.

The easiest and most reliable way of measuring seats for coolers is a measurement between the centers of the mounting holes. Measuring these distances, you can determine the size of the cooler based on the values ​​below.

Should you mount your Power Supply up or down?

Distance between mounting holes and cooler size:

  • 32 mm. 40 × 40 mm
  • 50 mm. 60 × 60 mm
  • 71.5 mm. 80 × 80 mm
  • 82.5 mm. 92 × 92 mm
  • 105 mm. 120 × 120 mm
  • 125 mm. 140 × 140 mm
  • 154/170 mm. 200 × 200 mm

Connecting coolers

All coolers are sold with a finished connector that you just need to connect to the same on the motherboard. Them can be like one and several. One of them is usually located near the connector to which the cooler of the processor is connected. The rest can be on the edge of the motherboard. This is done for the convenience of connecting the rear and front cooler.

Identify these connectors in size, the corresponding connector on the purchased cooler and the inscription “Fan” next to them.

ATTENTION. Connect the coolers to the motherboard when the computer is turned off. Disable also!

Before mounting on the case, you can first connect them to connectors on the board, turn on the computer, and see which side to turn them so that they work in the right direction. After that, you need to turn off the computer and consolidate the coolers in the right places with the help of screws. If there are silicone shock absorbers, they are also useful to use them to reduce noise levels.

Now you know how to install cooling coolers in the system unit. If you installed them yourself, check their work. If you’re just going to do this, make everything competently immediately.

First of all, I would like to note that the most correct will not be tormented by your old power supply, but buy a new, with the adjustment of the fan rotation speed. Such models in Russia are sold, although they find them in stores will be very difficult. We wrote about similar solutions in the report from the Spring Cebit 2002.

High-quality power supply with fan speed regulator

Separate set of fans for installation in PC or its BP

In addition, you can apply to the desktop PC concept adopted by most laptop manufacturers. So that the portable system does not heat up, as well as on the basis of a number of other reasons, the power supply is taken out. A similar method was used in PowerMac G4. But, to implement this method, it will be necessary much more than the tape and soldering iron, and only a person competent and experienced can decide on this. Simply put, the power supply is reassembered in another case, the wires from it are discharged inside the PC. PC itself is carefully analyzed and some stiff work is held.

Some users try at home to provide natural air craving inside PC, closing one holes and drilling others. But, this is a completely different story. If you have a similar experience, and you are ready to describe it, write on Stanislav @ 3DNews.Ru
