Why really hot laptop, what is the reason of its high temperature? What if the laptop is very noisy, inhibits, or even turned off? As a self-clean notebook cooling system from dust at home? How to prevent overheating of the laptop in the future? Does it make sense to buy a cooling rack or cooler for the laptop?
The article answers these and other questions regarding the laptop overheating.
In the process of laptop its components consume electricity and part of it is inevitably converted into heat. The most active consumers are the processor and graphics card, respectively, than they were more powerful – so hot is inside the notebook, and the trend is that the processor and graphics card for each new generation of notebooks designed for finer process technology, so similar in performance notebooks of previous generations are heated much more than more modern laptops.
Cheap budget notebooks tend to have low processing power, but they are also the least heated, universal models are usually heated much stronger, and most powerful gaming laptops have the date of purchase look like little noisy stove, especially in difficult games, so with the purchase of a powerful gaming laptop problem you get for free as a cool all this hot gaming power. In the case of computer games with overheating problems are usually absent, besides any gaming laptop is always weaker than the close on the price of a personal computer about 2 times.
Since all the laptops from one generation are made of the same or similar components, and for roughly the same technology, it can be heated greatly models of all manufacturers – Acer, Apple, Asus, Dell, HP, Lenovo, Samsung, Sony, etc., but in this primarily concerns the powerful gaming notebooks, which even under normal use (use cooling pad and regular cleaning of the cooling system) is still more prone to early failure and careless attitude (work in dusty environments and on porous surfaces without regular cleaning of the cooling system ) their lifetime before the first major repairs can be 2-3 years. Modern inexpensive laptops are not so demanding on the conditions of operation, because they do not have a discrete graphics card and chipset, and the processors are very resistant to overheating and even consume just 6 to 15 watts, so it is usually even completely clogged with dust cooling radiator dissipates enough heat.
The main components of which are heated in a laptop – this card (1, if any), the processor (2) and chipset (3, if equipped), and in a simple and low load heat generation is small, but with a full load of these components (heavy games, video conversion, opening a large number of pages in the browser), the temperature for several tens of seconds is raised to high values, followed by the heat pipe is transmitted to the radiator and the cooler (4), which emit excess heat out of the laptop.
While the laptop is new (within the radiator cooling, no dust), and the cooling system is designed correctly, it regularly removes heat from internal components. But over time, dust and shallow fluff accumulate in the radiator cooling system and are increasingly interfere with the normal release of excess heat out of the notebook, the internal notebook components will heat up until the command from the processor, graphics card or chipset does not work the emergency power-off to save them from burnout. Since each emergency shutdown occurs at critical temperatures, each time increasing the risk of complete failure of the laptop due to “dump” the chipset and graphics chip.
According to the tests, passive stand for laptop lowers the temperature of the internal components by 2-5 degrees, active (with built-in coolers) – to 3-8 degrees, ie, benefit from the cooling pads is not very big, much better to initially choose the right laptop is less hot or regularly on their own or in a service center to clean the cooling system.
The bottom surface of virtually all laptops are openings for fresh air intake – they should always be open. Working with the notebook on a soft surface (bed, sofa, carpet) greatly complicates the laptop cooling process, so the main thing you need to do – is to enter for myself a rule that a laptop must always stand on a hard, flat surface (table, coffee table, flat hard board ) or on the knees, not covering the ventilation openings.
If you install on a suitable surface the laptop is still constantly or intermittently really hot, your actions in this case will be different for different situations:
…, Then the nominal cooling system is not enough to release all the heat. If overheating is not very significant (body only much warmer in some places, but crashes the laptop never switches off), it is enough to set it on a special stand or raise a little back, for example, put a pencil. If the laptop overheating more significant (hot body, sometimes at high load emergency off), it means that particular instance has a built-in cooling system defects (warranty repair or exchange for another model) or without active cooling system can not do. Maybe it’s worth once again think about what is better to use a laptop for work and the Internet, and for high-end games is the best full gaming PC?
… It means that cooling the laptop inside the radiator clogged with dust or fibers. It is not necessary to delay the cleaning, because a short time in this mode can easily deprive your laptop desire to live forever. Reliable, but not the cheapest solution to this problem is to send the laptop to clean the service center. The cost of cleaning the notebook cooling system from dust, depending on the model may be different – from 4 to 40 USD, this variation is due to the availability of very different cooling systems in different models and balance of conscience / greed “cleaners” in the service center.
You can do differently and try on their own to clean notebook cooling system from dust. To do this, turn on the notebook, run any resource-intensive program (a game or open multiple pages in a browser), and wait for the laptop cooler is running at full capacity. Next, rapidly and briefly to blow into the laptop cooling radiator disposed at the rear end of the housing or (in the direction of yellow arrows) and immediately clean the face. Cooler stops and a moment later throw a portion of the dust through the radiator outside the laptop. The procedure can be repeated several times until the cooler will cease to dispose of the new portion of the dust.
Naturally, this method of self-cleaning of the cooling system from dust is not very aesthetically pleasing, but it is very simple and accessible to almost everyone – in most cases, “flies” in the opposite direction or disperse the cooler into smaller particles of up to 80% of dust and lint, overlapping heat sink, and this simple procedure can be repeated any number of times in a year. After blowing strongly powdery laptop you must pay attention to the air inlet at the bottom of the laptop, as there are large clumps of dust stuck that need to be removed, for example, from a thin wire hook.
It is very important – the air flow has to be strong, but short, not more than 1 second, therefore if to clean notebook cooling system use a compressor or another constant source of compressed air, in order to prevent failure of the cooler electronics must first block the blades with a thin flat object. , protisnuv it outside through the radiator fins all the way into the cooler shaft (1), or by locking blade cooler, if they are visible through the bottom of the notebook the air inlet (2). Of course, cleaning the compressor notebook cooling system is more efficient and performed at the unit is turned off and remove the battery.
If after cleaning the cooling notebook cooler is not included at all (it is not audible), then large chunks of compacted dust will not allow him to work. In this case, repeat cleaning until the complete removal.
… And cooling system noise is not audible at all, it means that the cooler is out of order. Replace the cooler is much more complicated and more expensive than just to make cleaning of the cooling system from dust, but sometimes can help to grease, but in any case – the problem is only solved by a trip to the service center. Typically, laptop cooler does not die in a day or a month, and this sad event is preceded by increasing noise from his work (crash, vibration, hum) due to the backlash of the rotor shaft cooler. If the time to lubricate his solid lubricant (grease, petroleum jelly or something more solid), then he will be able to work normally until the end of the life of the laptop, as there assigned to it by the manufacturer or by fate.
… (Typically 2-15 minutes under resistive load), then thermal grease on the video card, CPU or chipset lost their properties and should be replaced – in this case without a service center or a flat hand a good specialist can not do. The legend that the thermal grease must be replaced every year or two is true only in rare cases, as a good thermal paste (eg factory in most notebook models, or even cheap domestic KTP-8) usually maintains its properties for many years and does not require replacement.
Directly it does not depend on the cooling system, it is likely that a problem or viruses (the system slows down), or bad sectors on your hard drive (the system hangs for a few minutes, but the mouse works fine), or failure memory or chipset ( system hangs, the mouse does not respond). Accordingly, for different reasons and different solutions.
Usually laptop really hot because of dust and lint that clog the radiator cooling system, so a few simple rules will help you avoid problems with it overheating:
Before buying a laptop next try to remember the rule “Caesar, Caesar’s” and buy mobile work cheap budget laptops, and gaming – powerful gaming computers. Do not be deceived, for real gaming laptop does not happen.
As you can see, only a few simple rules can save your hot laptop from early retirement or an unplanned trip to the service center, so if the laptop has become much warm or even off – do not ignore, otherwise it could end up very sad.
