How much do you know about the cooling of the video card?

Entering the midsummer, it is also the season with the highest temperature in the year. In the hot summer days, people have used various summer tricks to spend the summer, cool air conditioning, blowing fans, swimming, Eating ice cream is the most common way for everyone to take a summer break. For high-temperature weather, many users, in addition to considering how to cool themselves, are also worried about whether their computers can survive in summer. We know that every component in the computer case will heat up as long as it works, especially the big heat card of the graphics card and CPU, which greatly affects the stability and service life of the computer.

Graphics card cooling problem is not only an important consideration for manufacturers, even users should always pay attention to the graphics card cooling problem, especially those who like overclocking, the heat generated by the graphics card after overclocking will be exponentially increasing, so good The cooling system is essential for high-performance graphics cards, and a variety of cooling methods are also emerging. So how is the graphics card cooling? The following small series will explain to you how the graphics card is cooled, so that friends can do the care of the graphics card.

A lot of graphics card manufacturers have installed cooling fans, but this kind of cooling fan can rarely achieve good heat dissipation effect. After all, in order to control the cost of the graphics card, some things can be saved. Many computer users have crashes and blue screens when playing games. There are also many computer enthusiasts who use the graphics when overclocking the graphics card. The reason for the mapping error is due to the poor heat dissipation of the graphics card. Therefore, if you have a similar phenomenon, it is necessary to add or modify a dedicated graphics card cooling fan.

Fan shape: The shape of the current cooling fan is generally square. Of course, some graphics cards have exceptions. For example, the shape of the cooling fan of the Geforce2 graphics card is a turbine shape. However, there is not enough evidence to show that the difference in shape will have an impact on heat dissipation. Fan size: The size of the cooling fan plays a key role in enabling optimal cooling of the display chip. Specifically, the size of the bottom area of ​​the fan is the best than the area on the display chip to be installed. If you see the cooling fan on the graphics card when you purchase it, it’s too "comfortable". That may not be A good thing, especially if you find that some fan bottom area size and display chip size are not bad, I advise you to "also find a new love"

blade design: now the graphics card cooling fan blades Most of them use a seven-leaf or nine-leaf turbine design (like a submarine propeller), which works well when dissipating heat. However, the cooling fan blades on ATI's latest Radeon 64MB DDR graphics accelerator card are designed for the nine-leaf erect type, and the effect is not bad. It seems that this blade design can only be said to have its own merits. Reasonable. Fan height: The design height of the cooling fan is not as high as the CPU fan. The thicker the better, the lower the temperature will affect the fan to dissipate the heat. If it is too high, it may conflict with the nearby expansion card or even affect the heat dissipation. The optimal design height of the cooling fan should be between l-1.5Cm, and the outer ring is preferably designed with a leaky bar and a flat design.

Fan classification: At present, the cooling fans of the graphics cards on the market can be described as various, but basically can be divided into two categories: ordinary fans and ball fans. Ordinary fans use oil to lubricate, and have the disadvantage of low wind power, short life, and high noise. Because it does not run for a long time, it is easy to cause the graphics card to crash due to overheating. In serious cases, there is still the possibility of burning the graphics chip. However, due to the low price, the inferior graphics card is generally used. The ball fan uses multiple steel balls as the ball. It reduces the friction of the medium, so it is characterized by large wind, long life, low noise and no need to add lubricating oil. It can usually be seen on the display card of famous brand manufacturers, but compared with ordinary fans, it is The price will be more expensive.

Through the above introduction, is there a certain understanding of the graphics card and the graphics card caused by one of the most important components in the computer, so it is necessary to use the computer in the future. Take care of your graphics card to prevent problems.
