The dirt and wear can cause overheating of the notebook.E damage even irreparably. We explain how keep the handset and the right temperature …
Excessive heat is one of the main enemies of the laptop, because it accelerates the electrochemical reactions that wear out the battery and that damage , often irreparably , the other components inside the chassis.
It is evident that placing the notebook near a radiator, near the oven or on a table exposed to the summer sun, can affect operation. In addition to external heat sources must , however, pay close attention to the internal ones , namely the processor, the graphics chip and the hard drive that overheat easily absorbing the energy. The high temperature of these three elements must then be lowered as quickly and effectively as possible to make sure that the circuits and transistors installed devices are not damaged . To avoid damage to the laptop is not enough to rely solely on the internal cooling system of the notebook.
There is a risk that the system fails : just that the fan speed is affected by sudden slowdowns or that special pasta (thermo – conductive ) placed between the chip and the heatsink also partially dislodged from one of the surfaces to which adheres to knock out the ‘ ” cooling system ” . Moreover, as we shall see, some laptops come with dissipation systems very inefficient . It is in particular economic models , characterized by a reduced thickness and equipped with a heat sink of small dimensions, little suitable to adequately disperse the heat generated by the CPU.
Internal cooling cooling systems for PCs are based on conduction through the metal components or ” convection “, that is the transfer of heat to the flow of air through the cooling ducts of the computer. Given that the portable air volume inside is lower than that circulates in much more spacious desktop PC , laptop cooling apparatus is based mainly on the run , and focuses on the fans and the heat sink . The latter is applied to a metal block on the processor and the hard disk. It is usually made of copper and it works like a finned which is crossed by the wind generated by the cooling fans.
Cool down an overheated laptop
The heat produced by peripheral spreads so that the air is dispersed into the environment coming out of the vents of the houses . The copper block placed on the chip particularly powerful is also crossed by special tubes , called heat pipes . These contain a liquid that has a low boiling temperature and that , vaporised , further facilitates the driving .
The heat sink is running on the physical principle of thermal inertia , ie the ability of the material to retain or release to the environment of the thermal wave generated by a heat source. Such inertia depends on the thermal capacity , the conductivity and thickness of the material itself. In other words this means that the greater the mass of the heat sink , the larger the amount of hot air that this spreads and which is then ejected from the ventilation system .
As was mentioned earlier some of the thinnest notebooks are usually equipped with a small block , then they have little “reserve ” in the moment in which they disperse the heat of CPU , especially when it is performing very intense work sessions such as those dedicated the preparation and reproduction of video game graphics .
External cleaning of your computer
Dust and dirt may prevent proper operation of the cooling system of the laptop
Consequently, the cooling fans should start at the highest speed in the shortest possible time to return to acceptable levels the temperature of the processor and the heatsink. Since the radiating surface of the latter is small, these laptops in the air must flow at very high speed to ensure effective cooling action : just partial obstruction of the slits or an accumulation of dust on the fins of the radiator to prevent the lowering of the temperature of the chip and make it rise above the alert level. In these cases, the CPU automatically decreases their ” rhythm of work ” for ” cool .” The hard drive or battery, however, does not have a system of automatic adjustment just as effective and can be damaged when their temperature exceeds the warning level of about 50 degrees. The same engine fan is heat sensitive : if it overheats , even its lubrication system may fail and generate scraping noises .
To prevent the heat generated by the operation of the processor and other components from damaging the laptop , do not primarily use the notebook in environments where dust is present in large quantities ( such as in a garage or on a sandy beach ) . The accumulation of dust is especially harmful to laptops that have vents on the bottom ( such as those equipped with a large screen ) . In their case, the air is in fact taken from the cavity located between the bottom of the notebook and the support surface and is ejected from slits on the side .
If the fans also suck the dust , it remains stuck in the grids and prevents air from passing . When this occurs , the fans start to spin at maximum speed to expel the air from the vents , while the computer system undergoes a sharp slowdown or even crashes. Also, if the laptop is a desktop replacement model , and that is a very powerful processor that requires a power supply of more than 100 watts , it adds another problem : since the heat sink of the chip is heavy , it is sufficient for a shock during transport loosen the screws that lock into the plastic frame . When the heatsink is not perfectly in contact with the processor of silicon, the conduction of heat is compromised. Also in this case the fans start to rotate at high speed , such as when dust has accumulated in the slots , but only cold air expelled from the handset . To resolve this situation we have to open the chassis , clean the fans , and , if necessary, tighten the screws which hold the heat sink.
Openings ventilation on the bottom must always be vacated
Temperature monitoring It is also a good idea to check the operation of cooling system and cooling using of specific programs. One of the most comprehensive is Speedfan for free download from the manufacturer’s website www.almico.com . This software analyzes the configuration hardware to obtain the necessary information in order to interpret correctly the measures temperature sensors that the operating system computer uses to adjust the fan speed . The program then displays all of this data via a convenient interface and provides the user the commands that allow you to configure fan speeds , bypassing so the control system automatic set up by BIOS and operating system installed in the handset . in many netbook models , the critical point is the temperature of the hard disk . This should not exceed 50 degrees and kept to under 40 . However, when the internal ventilation is poor, there is possibility that the temperature of the hard disk can rise to dangerous levels even above 60 degrees compromising so the whole system. It should then how to install a program that provides HDDLife Pro the temperature level of the hard disk .
The software can be download from http://hddlife.com/index.html provides for a trial period of 14 days after which must pay 20 euro for continue to use the application.

Desktop Replacement Particular category of notebook that includes models rather heavy and bulky, with a hardware configuration powerful and that, precisely for this, they are used as fixed location, to as a normal PC desktop with respect to which however, have a dimensions far lower.
Heat Pipe They are metal tubes that contain within them vapor and liquid (water, mercury, or methanol). Transfer the heat from a extreme (hot) to the other (cold) and are used for lower the temperature of processors.
Netbook this word are defined laptops extremely compact, Cheap, equipped with a hardware configuration limited and dedicated especially to navigation Internet and paperwork.
Notebook Cooler Cooling Pad
- The base must allow a stable support to the legs the handset.
- More fan blades are long, less rapidly must move to generate the amount of air required to cool the laptop. Regolate the inclination to find the best location ensuring at the same time that the laptop is well balance and its keyboard easily accessible.
- A temperature sensor integrated in the hub of the fan measure the air flow and controls the speed of rotation. The models Cheap does not have this sensor because operate at a fixed speed.
- The frame should be of metal to facilitate the conduction heat and having to walk support large and stable.
The power cord may end with a USB socket so you can also be connected to an external power supply.
