Notebook owners are well aware that if the internal cooling system of the electronic assistant is not cleaned from accumulated dust in time, then you can forget about stable operation: due to excessive temperature increases, various program failures will occur. Such cleaning also needs to be done with respect to personal computers, otherwise overheating of the video card or central processor will be only a matter of time. A significant proportion of calls to service centers is due precisely to the accumulation of dust in computer cases. Today we’ll talk about what overheating of a video card is and how to deal with it.
Long gone are the days when the functions of a video adapter came down only to converting digital signals into their analog form, "intelligible" to the monitor circuitry. Now, in the era of three-dimensional applications, these devices have their own mathematical processor. Often its computing power, just like the number of transistors involved, exceeds the capabilities of most central processors. A direct consequence of this is a high heating temperature, 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 air stream from the fan. A similar approach has already become a classic. But due to the additional fan, the total noise level of the system unit increases. Understanding this, alternative solutions based on heat pipes and heat-distributing metal fins were proposed, which made it possible to abandon the use of a fan - the so-called passive cooling.
Overheating of the video card represents an increase in the temperature of the video processor over the allowable limits.
There are several reasons for this:
- improper air circulation inside the system unit;
- fan malfunction;
- software error;
- hardware malfunction.
Passive-cooled graphics card allows you to build a low-noise computer system. In this case, the heatsinks of the video chip are cooled by a stream of air from an exhaust case fan or a 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 heat dissipation.
The next obvious cause of overheating is the fan stopping. This may occur due to jamming of the blades due to the accumulation of a large amount of dust. If the fan humming a lot during the first few minutes after turning on the computer, then it is almost certainly necessary to clean it from dust and lubricate the bearings.
Sometimes the reason for overheating lies in the unsuccessful version of the driver for the video card. Although this happens quite rarely, when overheating, it is worth trying to replace the driver. It is possible that he is the “culprit”.
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 failure of any of them. If there are electrolytic capacitors on the board, their condition should be checked periodically and, if swollen, appear, replace it. For example, a faulty capacitor in the power supply circuit of a video processor can lead to a change in voltage and, as a result, an increase in temperature.
In addition, do not forget about thermal grease - that small layer between the surface of the video chip and the radiator material. Over time, its ability to conduct heat deteriorates, which affects the general thermal regime.
Sometimes visitors to forums ask why the nvidia graphics card is overheating. In fact, it does not matter at all who the manufacturer is. Common causes are the same.
