What is overheating of the video card

Owners of laptops are well aware that if in time the internal cooling system of the electronic assistant can not be cleaned of accumulated dust, then it is possible to forget about stable operation: due to excessive temperature growth, various program failures will occur. Such cleaning also needs to be done for personal computers, otherwise the overheating of the video card or CPU will only be a matter of time. A significant share of calls to service centers occurs just due to the accumulation of dust in computer cases. Today, we will talk about what is the overheating of the video card and how to deal with it.

Long gone are the times when the functions of the video adapter were reduced only to the conversion of digital signals into their analog form, "understandable" the circuitry of the monitor. Now, in the era of three-dimensional applications, these devices are equipped with their own mathematical processor. Often its processing power, just like the number of transistors involved, exceeds the capabilities of most CPUs. A direct consequence of this is the high temperature of heating, especially for top models.

Manufacturers use several solutions to prevent overheating of the video card. The most effective way to moderate the hot fervor of modern video processors is to install a metal radiator on the chip, blown by the airflow from the fan. This approach has become a classic. But because of the additional fan, the total noise level of the system unit increases. Understanding this, alternative solutions were proposed on the basis of heat pipes and heat-distributing metal fins, which made it possible to abandon the use of a fan - the so-called passive cooling.

Overheating of the video card is an increase in the temperature of the video processor over the permissible limits.

There are several reasons for this:

- incorrect air circulation inside the system unit;

- Fan failure;

- program error;

- Hardware failure.

A video card with passive cooling allows you to assemble a low-noise computer system. The radiators of the video chip in this case are cooled by the air flow from the exhaust hull fan or the cooling system of the central processor. Thus, if the video card overheats, it is necessary to open the case and make sure that no interlacing of the cables does not interfere with the removal of heat.

The next obvious cause of overheating is the fan stop. This can occur due to wedging of the blades due to the accumulation of a large amount of dust. If the fan hums for the first few minutes after turning on the computer, it is almost certainly necessary to clean it from dust and lubricate the bearings.

Sometimes the cause of overheating is in the unfortunate version of the driver for the video card. Although this happens quite rarely, with overheating it is worth trying to replace the driver. It is possible that the "culprit" is he.

Any, even the most reliable video adapter consists of a huge number of electronic components. The longer the operating time, the higher the probability of any of them failing. If there are electrolytic capacitors on the board, their condition should be checked periodically and, when the swollen one appears, replace it. For example, a faulty capacitor in the power circuit of the video processor can lead to a voltage change and, as a result, a rise in temperature.

In addition, do not forget about the thermal paste - the small interlayer between the surface of the video chip and the material of the radiator. Over time, its property to conduct heat deteriorates, which affects the overall thermal regime.

Sometimes visitors on the forums ask why the nvidia graphics card overheats. In fact, it does not matter who the producer is. Common causes are the same.
