How to make an additional laptop fan. Additional cooling for laptops. Disadvantages of existing cooling systems

The laptop has long and firmly entered the lives of many of us as a mobile alternative. personal computer. And although B. lately Tablets are more confidently displacing their senior electronic fellow, laptops thanks larger screen, full-sized keyboard and other functional advantages remains enough a large number of Users, including me.
Despite the obvious ease of use mobile device Most users have sooner or later there is a problem overheating of the laptop, as a rule, one of the "heavy" applications is caused by the culprit. Another reason for overheating of the cooling system is hot weather, it is also possible that the ventilation grills turn out to be uncovered, so it often happens when the laptop is installed on a soft coating, such as a blanket. The standard cooling system does not cope with its work and resulting in a slowdown, hang, FPS drop in games. It is this sad circumstance that made me think about the additional cooling of the laptop.
Of course, many will see the question, and why not just buy a cooling stand in the store. It is possible in the store, but the high-quality stand will cost quite significant funds, in addition, I was just interested in making a cooling system with my own hands, especially since, by the nature of the activity, I was able to get most of the materials you need completely free.
So, by the nature of your activity, I was connected at that time with the assembly of plastic windows and doors, and I chose the basis for the stand one of the small segments of the plastic window sill. The windowsill is good in that it is two thin plates connected by ribs of stiffness, which felt in my idea.
So; Having come home, I brought the dimensions of the window sill before the size of the laptop, in my case it is Fujitsu AH 530, plus a centimeter of stock.

The next stage is a trip to the shop of computer goods in search of a suitable cooler, for my idea it was supposed to be a fan feeding from USB port laptop. However, I could not find the desired instance and I had to be content with an ordinary cooler with a size of 120 by 120 mm, a voltage of 12 volts, a strength of 300 milliam.

Put the cooler I decided to charge the car for the machine on the radio controlled remote. The stream of current charging provided almost the necessary - 250 milliamme apex, but voltage, only half of the permissible - 6 volts. Nevertheless, the propeller spinning pretty cheerfully, but at the same time quietly, that it was quite arranged. I decided to place the cooler in the stand in the place that the ventilation grille was supposed to be located under the processor, in order to further blow it down. To do this, I stood out the contours of the slot for the cooler and with the help of all the same "Bulgarians" cut it out. As it turned out in the future, it was not quite the optimal choice of the location of the additional fan, but this later.

The location of the laptop on the stand turned out to be the next - the front edge of the bottom of the laptop rests into the side of the window sill, which does not give it to slip from the stand even in a vertical location. Rear end The laptop is installed on a plastic stapper with a rubber edge - a seal, (screwed to the base by self-drawing), due to which it does not slide, besides the horizontal arrangement, the laptop keyboard is at an angle to the user and its use is quite comfortable.
Fan I installed parallel to the bottom of the laptop housing using an ordinary plumbing sealant. The presence of cavities inside the main part of the stand allows the cooler to freely pump the airflow, just through them can be displayed on any side of the wire from the fan. The plug for connecting the fan to the power unit had to be invented by itself in accordance with the connector on the WPP wire. To assemble the plug, a connector for wires was useful, the two screws of which I secured the wiring from the cooler, and the contacts served as a segment of the metal antenna from the broken control panel of the machine. Thanks to this design, the cooling power supply can be connected only if necessary.

So, after the manufacture of this illudive coolant, I, of course, decided to check it in action. For tests, the popular game of the World of Tanks was chosen, the FPS increase was about 5 to 10 points, the heating temperature was noticeably decreased. central processor, motherboard and hard disk laptop. The best cooling effect manifested itself when a little shifted to the side and the fan blew out the hot air of the lattice lattice.

The resulting design I consider it quite successful, the stand is used for cooling (especially drives off when working with a laptop in the evening in bed, on a blanket) and as an additional protection of the bottom of the laptop from possible external damage or random contact with water (happens on the kitchen Table). In the future I plan to put another cooler (the benefit of the free space is quite enough) due to which the cooling effect will increase.

Everyone knows that the temperature is the scourge of any computer. Acer Aspire 5920G (Acer Aspire 5920g) I was forced to make additional cooling.
Since mainly when working with heavy multimedia applications, all
The load falls on the video card and its temperature comes to critical - 97-99º, and this is dangerous! There are many models of cooling consoles on sale, but they
Roads and do not always satisfy their efficiency. My cooling cost me only 150 r.
In the store of radio components bought "Cooler" 12V - 60P
Turned his laptop and on back cover Over the video card sector (see .Ris.) Talked the diameter of the future hole for air supply from the cooler

The miniature drill twisted along the contour of the hole and sharpened flat screwdriver cut off the unnecessary circle

Processed a round file and glued the cooler for the marked marks.
The cooler is glued by any side, but since I already have a "native" exhaust cooler, I braided the new side to blow.
Next proceeded to its connection.

I take a cut USB cable 40-50cm and spawn the conclusions of the cooler red + and black - (the third output is unnecessary) with similar cables. Isolate and gently fix on the back cover. When installing, you need to consider everything your "wind" system

Free space, otherwise there will be no cooling. Have to
"Raise" a laptop. Stick corks from overflow system bubbles (beautiful and original

I also made an additional lifting bar

Corks from peniciline bubbles are glued so that they are included in traffic jams

That's all. 5.6V meals can be taken from any USB your laptop, but for
Games and other applications I connect to the 12V power supply unit. Now the new cooler for a couple with "native" is perfectly chasing the air, and the laptop pulls any games without much difficult for yourself. Temperature of the video adapter when working with such steep games like Tom Clancy "S Ghost Recon Future Soldier does not exceed
86-92º! Similarly, you can put additional cooler And on the processor, but it's an amateur.
P.S. Drinking over each dust and scratch, such a remake is a taboo! But agree, it is better to create favorable conditions for work to your device than
Turn to the service a completely new device. I hope that my laptop will still please me with good multimedia applications.

Greetings all the hubromeusers, today I will tell you how I made a simple and pretty budget cooling stand for a laptop.

For this we need:

1) Folder for A4 sheets, with as a rough cardboard, in my case it folder-folder with arched clamp, looks like this:

2) Fan from a computer with a size of 120 by 120 mm:

In my case, this is one of the most budgetary fans of Gembird Fancase3, it is designed for 2100 rpm, that is, "buzzing like a vacuum cleaner," but, nevertheless, unscrewed in my old computer for about three years and still works.
Of course, you can take a smaller fans, but 120-ki have an optimal price / performance ratio / noise.

3) collapsible USB plug Type A (fork / dad):

You can certainly get a USB extension cord, but somehow it's a pity to "put under the knife."

4) centimeters with 10 wires, if you decide to do, because I:

5) Knife, preferably sharp, screwdriver, marker / handle, tape or heat shrink (in the frame of the lens did not fall, but they are).

Production:
To begin with, we need to choose a place where the fan will be, I recommend choosing as close as possible to the end of the folder, and of course, consider the location of the laptop air holes and also, it is desirable to install the fan right under the hottest parts of the laptop, it is usually a processor or video card, or Both in one person (the video card integrated into the processor), such as I have. Someone will probably ask if you have an integrated video card, then it is most likely to be overheating, why then bother above additional system cooling? The answer is simple - purely sports interest, the idea is very simple, and everything except the folder was available.

After we have chosen the optimal location of the fan, or the fans (yes yes, the folder size allows you to install two 120 mm fan, if there is such a need, it will also make it possible to give the entire structure of the stiffness, which is clearly not enough, but about it later) Post the part that you need to cut:

Then you need to place holes for the fan screws:

It is convenient to do the charge from the ballpoint handles:

We pretend, whether we have calculated how the outdoor folder, where the laptop is standing and with the inner, where the fan actually will be.

As you can see, I could not make a hole under the fourth codkin, so the fan holds on three.

I got about 25 millimeters from the end of the folder, but I did specifically under my laptop so that the fan was as close as possible to the hot parts of the laptop.

As you can see, draw me really it does not work, so that here is a picture from Wikipedia:

Usually, Red fan wire is a plus, but black - minus, Yellow is monitoring revolutions, it does not interest us, like contacts D + and D-USB. So, A. it is important here after connecting wires to isolate everythingso that you accidentally do not arrange your laptop short circuitthat can negatively affect the pet itself, and do not say that I did not warn you.

If you still want to make a USB connector from a USB extension, then there is also the red wire is a plus and black - minus.

Of course, low food will affect the fan speed, they will fall at least twice, so I think that the fans are 800 rpm won't go for this, they may not start at all, ideally something at 1700-2500 rpm. But noisy fans, as a rule, become quiet with such revolutions and have a more or less air flow.

And a few words on installing a fan, I believe that it is better to put a fan so that he blows the air from under the Niza laptop, that is, "stood on blowing", as it is customary to speak between the "glands". Of course, no one forbids to put on the contrary, but then he will blow all the dust inside the laptop, think is it appropriate to bring the laptop cooling system or not?

Air flow, like the fan rotation side, are shown on the side.

As you can see in the photo, the arched clamp I removed, he interfered with me, I suppose what and you will be too, just beaten carefully with the score, however, everything is visible in the photo.

Advantages and disadvantages:
To the pros It is possible to attribute the simplicity of manufacture, it is thinking such a stand will not be difficult for anyone, after such a number of pictures that I did, low cost and flexibility, you can do specifically under your laptop, under the location of the laptop's air holes, the pleasure of doing something with your own hands, Buy can everyone.
To minuses You can attribute the harness of the design, just take a look:

It seems to me that this is not quite good if you have any ideas or thoughts write in the comments or in my profile there are links to Facebook and VKontakte. So far, I decided for myself so:

Although, I think it will be more correct to somehow like this:

Still to disadvantages, probably, will take a small efficiency, with tests, the temperature dropped only 2 degrees, but I believe that this is a lack of a laptop cooling system, if you unscrew the bottom cover to pull hot air straight from the heat pipes, then there will be a temperature drop obviously higher.
And the last disadvantage - since I have an old fan, 3 years old how to the engine with a sliding bearing is a large row, even for the baseless, slightly noticeable "hole" I believe that this is due to wear bearing.

Technique entered B. daily life each person. No longer thinking about the day without cell phone. Lootbkuki, netbooks, tablets and other modern portable electronics are sold in every digital technology store. Many hardware, many brands and different price categories. Technologies are also improved - phones are already dual-core, however, as well as tablets. Everything is done to automate all processes and everything seems to be fine, but everything has a reverse side ...

Cooling for a laptop with your own hands

Modern technique should be not only powerful, but also as comfortable as possible: multimedia, universally, portable and silent. And if it is enough for multimedia powerful processor, video card and memory modules, then for versatility it is already necessary to have various digital outputs and inputs for connecting other digital devices. Portability can boast a miniature device, such as a netbook, which must also be silent. Low noise is achieved by a solid-state hard disk (flash drive technology), and the absence of a processor cooling fan - passive cooling. The latter in my opinion has a pluses (dust from the fan on the radiator scores, the technique consumes less energy from the battery - it works longer, he needs costs) and minuses (at high temperature in the room, passive cooling is ineffective, reduction of power during overheating, the probability of exit out of service). All listed minuses can be crossed out with a good cooling for a laptop.

In stores, with money, you can buy anything. But not all that is good that shines! Sometimes made at home works much more stable than the factory. Give specific example. Recently bought myself netbook asus last modelwhich is not surprised by the factory fan of cooling processor. With small works, the regular radiator copes with the output of the para-heat from the chip, but here maximum performance The bottom starts to be very hot - while the programs are noticeably slowed down. I tried to find the cooling coasters of small sizes specifically for netbooks - it was possible, but the effectiveness is very low. The fact is that all store stands work from USB, which has low voltage - As a result, the blades accelerate quite on small revolutions. The air flow is not enough for a full-fledged blowing into small bottom compartments. The output as always did not make it wait - it is necessary to make a cooling for a laptop with your own hands.

The cooling system shown below is designed for a netbook that works remotely around the clock. Its location does not need convenience. If you plan to work on the keyboard or touchpad of the device, then make inclined legs, while moveing \u200b\u200bthe fans to the long area (as a rule, in the corner there is a processor cooling system), select narrow coolers.

Cooling

The design was manufactured for home use - All Pontes go face, the main functionality and not a big value.

In the process, we will need basic materials:
Cooling fan - 2pcs 40 rubles \u003d 80 rubles.
Isol - 10 rubles.
Power supply - taken from old charging Cell.
PVC plate - 40 rubles.

Accessories:
Connectors - 3 pcs 3 rub \u003d 9 rub.
Development of connectors - 10 rubles.
Crimping for connectors - always in your pocket 🙂
Screws for fastening - existed
Rake about half meter - I had
Stationery knife - is available.
Pen and ruler - in stock.
Straight hands patience and work hour - always eat.
Screwdriver and pliers - well, this good in every house is probably in bulk.

At the same time, the connectors are used for convenience - you can do without them simple twisting of the wires. Those. Crimple, connectors and a fork can be safely excluded from the list in their absence!

As an avid IT shop, the following tools were first on the table:

Cooling manufacturing process for netbook

1. So, we take the PVC sheet (sold in construction stores) the size of a little larger bottom of the netbook. In the middle, we cut two circles with a stationery knife - diameter of exactly under the blades of the fan.
2. We screw the fan into the factory fastening compartments. Screws can be screwed into small PVC pieces
3. On the sides of a wooden rail, we manufacture legs with a height of 0.5-1 cm higher than the installed fan - for good air intake
4. Attach the power supply - only red and black wire are used, the blue is not needed - it is used in computers for speed control.

As a result, we get something like this:


5. From the upper side of the sides of the Freaks, with the help of screws, two rails are needed for Ventilation by Wilch.


6. As a result, we get ready, a powerful cooling tablet, which is done with your own hands.

Suitable

As a result, we got very good tool cooling, while the cost does not exceed 150 rubles. The whole process took about 1 hour. It was not very impressed - it was possible to do in more beautiful, but the quality is important for me, and not aesthetic appearance. Everything is simple - this netbook is part of round-the-clock scrolling systems and analyzing key queries. I appeal to him only once a day to track the work process.
