Factory water cooling for a laptop. Asus announced a water-cooled laptop

In this article I will try to talk about my attempt to make a water cooling system for a processor at home. At the same time, I will describe the main points and technical subtleties using the example of my own experience. If you are interested in a detailed illustrated guide to the manufacture, assembly and installation of such a system, then welcome to cat.

Traffic, lots of pictures! Video of the manufacturing process at the very bottom.

The idea of creating more efficient cooling for my home computer arose while searching for a way to increase the performance of my computer by “overclocking” the processor. An overclocked processor consumes one and a half times more power and heats up accordingly. The main limiter to buying a ready-made one is the price; buying a ready-made water cooling system in a store is unlikely to cost less than a hundred dollars. And budget liquid cooling systems are not particularly praised in reviews. So it was decided to make the simplest SVO independently and at minimal cost.

Theory and assembly

Main details

Water block (or heat exchanger)
Centrifugal water pump (pump) with a capacity of 600 liters/hour.
Cooling radiator (automotive)
Expansion tank for coolant (water)
Hoses 10-12 mm;
Fans with a diameter of 120mm (4 pieces)
Fan power supply
Consumables

Water block

The main task of the water block is to quickly remove heat from the processor and transfer it to the coolant. Copper is most suitable for these purposes. It is possible to make a heat exchanger from aluminum, but its thermal conductivity (230 W/(m*K)) is half that of copper (395.4 W/(m*K)). The design of the water block (or heat exchanger) is also important. The heat exchanger device consists of one or more continuous channels passing through the entire internal volume of the water block. It is important to maximize the surface of contact with water and avoid stagnation of water. To increase the surface, frequent cuts are usually used on the walls of the water block or small needle radiators are installed.

I wasn't trying to make anything complicated so I started making a simple water container with two holes for the tubing. The basis was a brass pipe connector, and the base was a copper plate 2 millimeters thick. Two copper tubes of the same diameter as the hose are inserted into the same plate from above. Everything is soldered with tin-lead solder. When making a larger water block, at first I didn’t think about its weight. When assembled with hoses and water, more than 300 grams will hang on the motherboard, and to make it lighter we had to use additional fasteners for the hoses.

Material: copper, brass
Connection diameter: 10 mm
Soldering: Tin-lead solder
Mounting method: screws to the store cooler mount, hoses are secured with clamps
Price: about 100 rubles

Sawing and soldering

Pump

Pumps can be external or submersible. The first one only passes it through itself, and the second one pushes it out, being immersed in it. Here we use a submersible one, placed in a container with water. I couldn’t find an external one, I looked in pet stores, and they only had submersible aquarium pumps. Power from 200 to 1400 liters per hour price from 500 to 2000 rubles. Powered from an outlet, power from 4 to 20 watts. On a hard surface the pump makes a lot of noise, but on foam rubber the noise is insignificant. A jar containing a pump was used as a water reservoir. To connect the silicone hoses, steel clamps with screws were used. To make it easy to put on and remove the hoses, you can use an odorless lubricant.

Water rise height – 80 cm
Voltage – 220V
Power – 6 W

Radiator

The quality of the radiator will largely determine the efficiency of the entire water cooling system. Here we used a car radiator heating system (stove) from a nine, bought an old one at a flea market for 100 rubles. Unfortunately, the interval between the plates in it turned out to be less than a millimeter, so I had to manually move apart and compress the plates several at a time so that weak Chinese fans could blow it through.

Tube material: copper
Fin material: aluminum
Size: 35x20x5 cm
Connection diameter: 14 mm
Price: 100 rubles

Airflow

The radiator is blown by two pairs of 12 cm fans at the front and rear. It was not possible to power 4 fans from the system unit during testing, so we had to assemble a simple 12-volt power supply. The fans were connected in parallel and connected according to polarity. This is important, otherwise the fan will most likely be damaged. The cooler has 3 wires: black (ground), red (+12V) and yellow (speed value).

Material: Chinese plastic
Diameter: 12 cm
Voltage: 12V
Current: 0.15 A
Price: 80*4 rubles

Note to the hostess

I did not set the goal of reducing noise because of the cost of the fans. So a fan for 100 rubles is made of black plastic and consumes 150 milliamps of current. These are the ones I used to blow the radiator, it blows weakly, but it’s cheap. Already for 200-300 rubles you can find much more powerful and beautiful models with a consumption of 300-600 milliamps, but at maximum speed they are noisy. This can be solved with silicone gaskets and anti-vibration mounts, but for me the minimum cost was decisive.

power unit

If you don’t have a ready-made one at hand, you can assemble the simplest of available materials and a microcircuit that costs less than 100 rubles. For 4 fans, a current of 0.6 A is required and a little in reserve. The microcircuit provides approximately 1 ampere at a voltage of 9 to 15 volts, depending on the model. You can use any model, setting 12 volts with a variable resistor.

I didn’t have to test it for a particularly long time, because... the results did not even come close to the capabilities of an air cooler. The radiator of the air cooler has so far been blown by only two Chinese fans out of 4 possible, and they have not yet been spread wider than the plates for better ventilation. So, in energy saving mode and zero load, the processor temperature in air is approximately 42 degrees, and in a homemade air cooler it is 57 degrees. Running the prime95 test on 4 threads (50% load) warms up to 65 degrees in air and up to 100 degrees in 30 seconds in the air cooler. When overclocking, the results are even worse.

An attempt was made to make a new water block with a thinner (0.5 mm) copper base plate and almost three times more spacious inside, albeit from the same materials (copper + brass). The plates in the radiator were moved apart for better ventilation and two more fans were added, now there are 4 of them. This time, in power saving mode and zero load, the processor temperature in the air is approximately 42 degrees, and in a homemade air cooler it is approximately 55 degrees. Running the prime95 test on 4 threads (50% load) warms up to 65 degrees in air and up to 83 degrees in CBO. But at the same time, the water in the circuit begins to heat up quite quickly and after 5-7 minutes the processor temperature reaches 96 degrees. These are readings without overclocking.

Assembling the SVO was, of course, interesting, but it was not possible to use it to cool a modern processor. In older computers, a stock cooler works great. Maybe I selected low-quality materials or made the water block incorrectly, but it doesn’t seem possible to assemble a water block for less than 1000 rubles at home. After reading reviews of budget ready-made air coolers available in stores, I did not expect that my homemade product would be better than a good air cooler. I concluded for myself that it is not worth saving in the future on components for the air defense system. When I decide to buy an SVO for overclocking, I will definitely assemble it myself from separate parts.

As is known, the lifespan of semiconductor elements strongly depends on the temperature at which they operate. Often, a standard laptop cooling system does not cope well with heavy loads, so coolers have to work at full capacity. And in idle mode, that is, without load, in most laptops the fan turns on from time to time, distracting attention. Such alternating on/off of the cooler leads to surges in the processor temperature, which negatively affects its service life. After all, a body expands when heated, and contracts when cooled. Even though these changes in size amount to millionths of a micron, over time the semiconductor ages.

To extend the life of my laptop, immediately after purchasing it, I decided to make a cooling system for it with my own hands.

Disadvantages of existing cooling systems

After looking at different devices on the Internet, I noticed that most of them cool the laptop body directly. At the same time, their efficiency turns out to be very low. But every laptop has ventilation holes through which the radiator is visible. And this radiator cools the processor and other components. This means that you need to help the built-in cooler remove heat from the radiator.

Homemade cooling system

Photos

Here's what came out of it:

Description

I have Asus X51RL. I can say that I was lucky because its radiator does not come out from the side, but from the back. Thanks to this, the homemade system stands at the back and is covered by a screen. Before installing this device, the processor temperature in quiet operation mode rose to 55 degrees, then the standard fan turned on, reduced the temperature to 47 degrees and turned off. And so on every five minutes. Naturally, this harmed the processor and my nerves. After installing a man-made cooling system, the processor temperature is constantly kept at around 43-45 degrees. That is, the temperature dropped by an average of 10 degrees. The standard cooler is resting. It sometimes connects at the lowest speed in games and during heavy archiving. Due to the fact that the device sucks air through the radiator, the overall temperature of the laptop has decreased and it does not heat up. For example, before installing the system, the hard drive was heated to 45-50 degrees, but now it is no more than 40.

Design

The design is very simple. The body is made from a piece of cardboard from a paper folder. In principle, it can be made from anything. The fan is a standard 120 mm cooler for a 12 volt system unit. It can be powered from the built-in USB port of the laptop, but there is a risk of burning it if there is a short circuit. Therefore, it is better to buy the simplest 12 volt power supply. If the cooler seems too noisy when powered by 12 volts, you can easily reduce the voltage using a resistor. The cardboard and cooler are glued with glue and additionally secured with insulating tape. The inlet of the cooling system must be in tight contact with the radiator opening.

Operating experience

More than 5 months have passed since the start of this installation. I decided to clean my laptop from dust and wrote an article about it. If you read it and looked at the photos, you will notice that a very thin layer of dust has accumulated inside the back cover. As it turned out, the homemade cooling system literally sucked out all the air by force. A layer of dust appeared on the cooler impeller.

Thus, this device prevented the accumulation of dirt inside the laptop. For preventative purposes, I supplemented the lubrication of its bearing with machine oil.

Not only ASUS knows how to “shoe a flea.” MSI, no less famous for gaming laptops, can also offer the buyer something exotic for an almost equally impressive amount. The laptop with such a long name that I won’t copy and paste it from the subtitle, so as not to bother you with trying to read it all, has an 18.4-inch screen with the same Full HD resolution, the same Intel Core i7 processor - 6820HK and - this point is especially worth noting - two desktop video cards NVIDIA GTX GeForce 980. I won’t lie when I say that the “machine” turned out to be healthy - almost 5 kg in weight and 5 cm in thickness. The device, despite all the designers’ attempts, looks like a not-so-pretty suitcase. The suitcase, by the way, can surprise you with a real mechanical keyboard. True, a gamer is not necessarily a fan of a mechanical keyboard, but, one way or another, the idea is interesting and definitely worth noting. The amount of RAM is the same as that of the ASUS ROG GX700VO - 32 GB. And for permanent data storage, the MSI GT80S 6QF has more space - a 512 GB solid-state drive (PCIe 3.0, NVMe - everything like in the best laptops), and a terabyte hard drive. Let me remind you that the ASUS ROG GX700VO cannot boast of having an HDD, and you cannot install all your favorite games on two 256 GB SSDs. If you believe foreign portals about hardware and gadgets, then in the vast majority of games the MSI GT80S 6QF with a combination of two desktop NVIDIA GeForce 980 produces 100 or more frames per second in Full HD resolution and at maximum settings. I think that's all there is to know about its performance.

At the annual consumer electronics exhibition IFA 2015 in Berlin, ASUS showed a pre-production sample of a gaming laptop with a water cooling system. It is installed in a volumetric docking station containing a reservoir, pump, radiator and heat pipes.

When calling laptops “gaming”, you usually have to make various reservations. The dimensions of the case and the cooling system of mobile systems impose their limitations. Compared to PCs, laptops use less powerful and “hot” mobile series chips, and overclocking, if possible, is only formal. It looks like ASUS has decided to rectify the situation by releasing a real gaming monster.

The GX700 laptop in various configurations will join the famous ROG (Republic Of Gamers) series. It will install one of the top Intel processors with the sixth generation Core architecture (Skylake family) and an unlocked multiplier (index “K”).

According to preliminary data, the configuration options will include versions ranging from $1,399 to $2,499. It is expected that the younger model will receive a Core i7-6700HQ and 16 GB of RAM. The most “charged” will be a laptop with a Core i7-6820HK processor (four cores with Hyper-Threading) and 64 GB DDR4. The disk subsystem of any version of the GX700 can be represented by HDD, SSD, or a combination of both. Drives with SATA 3 and M.2 PCI-Express interfaces are supported.

Overall, the GX700 looks very large, even by gaming laptop standards. Its prominent (literally) back contains a module for connecting to a cooling dock. Details of the design are not officially reported, but according to indirect evidence, it contains copper contact plates to which heat pipes are soldered.

Thanks to water cooling, for the first time it became possible to use aggressive overclocking and powerful video cards with heat dissipation over 120 W in a laptop for a long time (up to Nvidia GTX 980M 8 GB). The lowest version of the GX700 will receive a GeForce GTX 965M (TDP module for connecting to the docking station of the GX700 laptop (image: ASUS).

As soon as you connect the laptop to the docking station, the cooling switches to water (more precisely, hybrid), and the overclocking settings are unlocked. In this model, overclocking is provided initially for the processor, memory and video card. In Full HD resolution, most games would demonstrate a comfortable FPS level without overclocking, but a 4K display increases the requirements threefold.

The estimated date for the GX700 to go on sale is the fourth quarter of this year. Like many other manufacturers, ASUS first waited for the official presentation of Windows 10 (which will be installed on this gaming laptop) and Skylake processors, the full series of which was presented only today.

Gaming laptops are often criticized for their lower performance compared to desktops. But what if the laptop is not inferior in performance even to gaming PCs? We received a model from the ASUS Republic of Gamers series for review, called the GX700. It is equipped with an NVIDIA GeForce GTX 980 desktop video card, 64 GB of RAM, and a water-cooled docking station. Let's see what this extraordinary laptop can do.

Scope of delivery

The ASUS GX700 arrived in a suitcase, which is included in its delivery package; inside there was also a docking station with a 330 W power supply, a separate 180 W power supply for the laptop and a wired optical mouse ROG SICA.

The ASUS package, traditional for the Republic of Gamers series, had to be changed, since the docking station with the laptop does not fit in the backpack.

The laptop came to us with a test case without branding, but in reality it will look like this:

As you can see, the suitcase will be painted in the signature colors of the ROG series.

Design and materials

The design of the ASUS GX700 is made in the same style as the previous flagship solutions in the Republic of Gamers line; in particular, it is almost a copy of the G752 model. In addition, the laptop’s identity can be easily recognized by the proprietary cover with the ROG logo and two beveled lines, which are also illuminated in this model.

The designers also retained the aggressive style of the ventilation grilles located on the rear edge of the ASUS GX700.

The laptop's display unit is slightly shorter than the base, so when opened, there is still a protrusion behind it that smoothly flows into the ventilation holes.

There are also connectors for connecting a water-cooled docking station.

Despite its impressive specifications, the ASUS GX700 is no larger or thicker than other 17-inch models. Its dimensions are 429x309x33-35 mm, and its weight is almost 4 kg. The main material of the laptop is matte-painted metal, and only the display frame and the surface under the keyboard and around the touchpad are made of plastic.

The body materials leave a pleasant feeling, but the soft surface of the rubberized plastic easily collects traces of the palm and fingers.

As for the assembly, the ASUS GX700 is generally good; the moving parts of the case fit tightly, but the plastic under the keyboard is pressed through. Perhaps this is a feature of our test sample, because this should not happen in such an expensive laptop.

Display

The ASUS GX700 uses a 17.3-inch display; the test model was equipped with an LG IPS matrix with a resolution of 1920x1080 pixels. Not the most modern resolution for a top-end gaming laptop, but it is enough for comfortable use, especially since the screen itself is very good. It has excellent color rendering and viewing angles.

The minimum brightness is a little high and is 34 cd/m2, the maximum is at 311 cd/m2, and the contrast is 651:1. Factory calibration is performed at a good level, the display provides almost 100% coverage of the sRGB color space, its color temperature is at the level of 6500K, gamma is 2.2, and the backlight is uniform.

At the same time, the ASUS GX700 screen supports NVIDIA G-SYNC technology, which synchronizes the screen update with the number of frames per second that the video card produces in the game.

This reduces the load on the processor. This technology is not supported in all monitors, so ASUS is a separate plus for its implementation in a laptop.

Performance

Just by the appearance of the ASUS GX700 with a docking station, one can assume that this is a powerful laptop. But it’s unlikely that anyone will be able to say at first glance that the performance of this model goes far beyond the usual laptops.

The ASUS GX700 has a 4-core 14-nanometer Intel Core i7-6820HK processor with a frequency of 2.7 GHz (3.6 GHz in TurboBoost mode). This is a mobile solution that nevertheless comes with an unlocked multiplier. Thus, the processor in the ASUS GX700 can be overclocked not only by increasing the reference bus frequency, but also by a multiplier.

The RAM capacity of our test laptop configuration was 64 GB of DDR4 memory operating at 2400 MHz, which can be overclocked to 2800 MHz.

But the most interesting thing is the implementation of the ASUS GX700 graphics system. The laptop uses a 28-nanometer desktop video card NVIDIA GeForce GTX980 with 8 GB of GDDR5 RAM. At the same time, the built-in video in the system is disabled; the GX700, even on battery power, only works with discrete graphics.

The storage system in the ASUS GX700 consists of two 512 GB SSD NVMe drives connected in a RAID 0 array. It provides very high write and read speeds, which, according to the CrystalDiskMark test, reaches 2965 MB/s read and 2607 MB/s write .

When the laptop is running without a docking station on the supplied 180 W power supply, it demonstrates not the maximum, but nevertheless impressive results in synthetic tests.

In the PCMark 8 Home 3.0 test it scores 4781 points, which is a very good result.

For comparison, a gaming laptop with an Intel Core i7-6700HQ 2.6 GHz Skylake processor scores noticeably lower:

In the 3DMark Fire Strike test, the NVIDIA GeForce GTX980 video card in the ASUS GX700 scores an impressive 9363 points.

For comparison, the top-end discrete mobile graphics NVIDIA GeForce GTX980M scores 7743 points:

As you can see, on its own, the ASUS GX700 is already an impressive gaming solution. But connecting a docking station allows you to further reveal its capabilities.

Water-cooled docking station, overclocking and heating

For such a powerful configuration, the laptop required an extraordinary cooling system, and ASUS found a solution. The GX700 comes complete with a docking station equipped with a water cooling system. There are no additional connectors on it, and the main task is to provide the laptop with power from the 330 W unit and effective cooling.

The latter is implemented through a special connector that allows liquid to circulate inside the laptop and remove heat through the docking station. The laptop itself also has fans that turn on when used without a dock, but it is worth noting that the ASUS GX700 itself is not very noisy.

How hot does the graphics card of a laptop without a docking station get? When playing Fallout 4 on ultra graphics settings for an hour without water cooling, the video card warms up to 60 degrees Celsius on average, while in similar conditions with a docking station its maximum temperature is 47 degrees Celsius.

One could also assume that without a docking station, the performance of the ASUS GX700 noticeably sags, due to the fact that the laptop can cut frequencies when running on a 180 W power supply. In reality, the user is unlikely to notice much of a difference in everyday tasks or even in most games. Nevertheless, it really exists, although not for all parameters. For example, the ASUS GX700 processor, based on the PCMark 8 Home 3.0 test, both with and without a docking station, demonstrates comparable results:

But judging by 3DMark FireStrike, the docking station provides a noticeable performance increase just for the video card:

But in addition to the water cooling system and increasing the frequency of the video card, the docking station also allows you to overclock the processor, RAM and video card through the ROG Gaming Center utility.

By default, the program, when switching to manual mode, accelerates the four processor cores to 4 GHz (the multiplier is set to 40, the reference bus is 100 MHz), the processor frequency of the video card and the memory frequency are increased by 100 MHz. All these parameters can be further increased, but this will not give a noticeable increase in performance. In addition, in ROG Gaming Center you can activate the XMP profile, which allows you to increase the RAM frequency up to 2800 MHz.

All manipulations with overclocking in the ROG Gaming Center increase the performance of the laptop, but in fact you don’t notice it, although in synthetic tests the results of the laptop after overclocking differ.

In general, the performance of the ASUS GX700 even without overclocking is enough to play at maximum settings. But for a number of tasks that place maximum load on all processor cores (for example, rendering), the performance increase is really noticeable. This is clearly visible in the Cinebench test, which loads the processor on all 4 cores and 8 threads. Without overclocking, ASUS GX700 scores 656 points.

But if you overclock all four processor cores to 4000 MHz, then the laptop already produces 845 points in Cinebench.

As can be seen from the test results, the ASUS GX700 has high performance, which is comparable to the best desktop gaming solutions. In its laptop, ASUS used a powerful overclockable mobile processor, a large amount of fast RAM and a high-performance desktop-class video card, seasoning it all with a water cooling system. Whatever one may say, it turned out to be an excellent gaming solution.

Connectors

ASUS GX700 has all the connectors necessary for a modern laptop.

On the left side of its body there is a USB 3.0 port, HDMI, Mini DisplayPort, two USB Type-C, as well as Gigabit Ethernet, covered with a sliding flap.

On the right side there are two USB 3.0 ports, a microphone and headphone jack, and a slot for SD cards.

Considering the presence of all popular connectors for connecting peripherals, including two new USB-C, the ASUS GX700 is unlikely to have compatibility problems in the next couple of years.

Keyboard and touchpad

The ASUS GX700 uses a full-size keyboard with a red backlight and dedicated WASD keys, which is virtually standard for Republic of Gamers series laptops.

Its buttons are well spaced and pressed with a soft stroke. The keyboard has three gradations of backlight and the ability to activate the backlight only on the left side.

In addition, above the ASUS GX700 keyboard there are six additional buttons, the first of which is responsible for calling the XSplit program for streaming games, and the remaining five can be assigned to quickly launch any applications.

The touchpad in the ASUS GX700 is quite large and recognizes touches and finger positioning well.

Below it are mechanical keys that simulate right and left mouse clicks.

Speakers and sound

Focusing on the performance of the ASUS GX700, the developers paid minimal attention to the external speakers of the laptop. They are not very large, and are located on the right and left sides of the keyboard, as well as on the right and left edges of the case.

They sound mediocre and quiet, so hardly anyone would want to listen to music with them. The quality of external speakers is not the most important indicator in a gaming laptop, but for their money, the ASUS GX700 could offer users better solutions.
There are no complaints about the sound that the laptop produces through headphones; it sounds good and has a large volume reserve.

Autonomy

The ASUS GX700 has a non-removable 8-cell 90 Wh battery. You shouldn’t expect high battery life from a gaming laptop, especially without switching to integrated graphics.

However, the ASUS GX700 lasts longer than you might expect. In the BatteryEater test with brightness set to 50%, the laptop lasted 1 hour and 32 minutes before being completely discharged under high load.

In reading mode, its operating time reached 3 hours 39 minutes.

On average, a user can count on two hours of productive work with the ASUS GX700 in offline mode.

As a result

ASUS GX700 is the flagship of the Republic of Gamers series and one of the most powerful gaming laptops in the world. At the same time, the model is designed not so much for enthusiasts for whom any increase in performance is important, but for ordinary users who simply want the most powerful laptop and are willing to pay any money for it. After all, overclocking capabilities are implemented in the ASUS GX700 as simply as possible; even a child can handle them. Therefore, this model should be classified as a status model, especially considering the cost of about $5,000. Just as a supercar does not make the owner a racer, but gives the opportunity to feel like one, the ASUS GX700 does not make a person a super player or an overclocking master, but gives a lot of positive emotions and the opportunity to play the heaviest games on a still portable device.
