Laptop processor temperature: how to recognize it

Every owner of a mobile computer mustKnow what the temperature of the laptop's processor is at any arbitrary point in time. If it is desirable for personal computers with full-sized cases, laptops are absolutely necessary. Despite the use of energy-efficient components in them, due to the insufficient dimensions of the cooling elements and the small internal volume of the case, the temperature of the notebook processor often reaches its limiting values, which can not but affect the performance.

All is explained quite simply: In addition to the CPU (CPU), there are a number of other components inside the laptop, such as a hard drive, memory modules, motherboard, etc. At high computing loads (converting multimedia files, modern computer games), the thermal power dissipated by the processor increases to the maximum, depending on the applicable CPU model. In addition, the heat in the body is brought by the video card and hard disk.

As a result, the temperature of all components reacheshigh values, which can cause bad sectors on the hard drive (the screw "fell down"), and the heating elements affect negatively on the elements of the motherboard. It is worthless to trust the active cooling system (fan, heat pipes, radiator), as its effectiveness decreases with time. Why? Because it is gradually clogged with household dust, and the resulting performance is reduced, therefore, by systematically monitoring the temperature, you can not only indirectly determine the need to clean the internal components of dust, but also to protect the components from completely unnecessary overheating.

Fortunately, the described situation can be avoided if you know what is the normal temperature of the notebook processor. There are three ways to determine it:

- to study on forums the responses of owners of similar models and for the reference point to take an average value;

- Immediately after buying a new laptop you need to load it with calculations and find out at what temperature value its growth will stop;

- if the first two methods give approximateresults, then for exact data you need to go to the site of the manufacturer of the CPU and in the given specifications to find the permissible value. Important: the temperature of the processor of the laptop, displayed on the manufacturer's website, shows not the nominal, but its limiting value. In other words, the processor may long hang from overheating, but remain unscathed.

For example, on the Intel site in the mobile sectionprocessors can be found, what is the normal temperature of the core 2 duo processor - it is usually 30% below the limit (note: the limit is specified). For the model P7550 it is indicated that its limit is 90 degrees, so hangups can be expected when heated to 60-70 ° Celsius, although this depends on the series.

It is completely unclear why the corporationMicrosoft has not yet included an informative panel displaying the temperature in its operating systems. The reality is that you have to install third-party software solutions in order to determine what is the temperature of the notebook processor.

It is possible to recommend the use of specialprograms that read the temperature value. By periodically monitoring the heating, it is possible to determine at which points in time the CPU is loaded with computations and it is better to refrain from setting additional tasks for it. One of the best such programs is the free Core Temp. After installation, an icon appears in the system tray displaying the temperature of each kernel.

You can also use the programs AIDA64 and SiSoft Sadra. In order to see the CPU temperature in the first one, you should follow it in the path "Computer - Sensors". Values ​​are displayed for each kernel.

Do not forget about the well-known application of Speed ​​Fan, whose capabilities are much wider than the simple reading of sensor values.
