Coneixements de refrigeració de targetes gràfiques

      Many graphics card manufacturers have installed cooling fans, but few of them can really achieve good cooling effect. After all, in order to control the cost of graphics cards, some things need to be saved. Many computer users crash and blue screen when playing games, and many computer enthusiasts have flower screens when overclocking graphics cards, A large part of the reason for mapping errors is due to poor heat dissipation of the graphics card. Therefore, if you have a similar phenomenon, it is necessary to add or modify a special graphics card cooling fan.

Forma del ventilador:

       Now the shape of the cooling fan is generally square. Of course, there will be exceptions for some graphics cards. For example, the shape of the cooling fan of Geng Geforce2 graphics card is a turbine shape. However, there is not enough evidence that the difference of shape will affect the heat dissipation.

Mida del ventilador:

      The size of the cooling fan plays a key role in the optimal cooling of the display chip. Specifically, the size of the fan bottom area is larger than the area of the display chip to be installed.

Disseny de la pala del ventilador:

     At present, the blades of the cooling fan of the graphics card mostly adopt the seven blade or nine blade vortex wheel design (such as the propeller of a submarine), which has a good effect in cooling. However, the cooling fan blades on ATI's latest radeon 64MB DDR graphics accelerator are nine leaf vertical design, and their use effect is not bad.

Alçada del ventilador:

        The design height of the cooling fan is not as high (thick) as that of the CPU fan. Too low will affect the fan to dissipate heat. Too high may conflict with the nearby expansion card and even affect the cooling. The optimum design height of the cooling fan should be between l-1.5cm, and the outer ring should be of flat design with leakage bar, so that the cooling effect of the cooling fan will be obvious.

     Actualment, hi ha molts ventiladors de refrigeració per a targetes gràfiques al mercat, que es poden dividir en ventiladors normals i ventiladors de bola en conjunt. Els ventiladors normals utilitzen oli per a la lubricació. Els seus desavantatges són una força del vent petita, una vida útil curta i un alt soroll. És fàcil fer que la targeta gràfica es bloquegi a causa del sobreescalfament. En casos greus, és possible cremar el xip de la targeta gràfica. Tanmateix, a causa del preu baix, la majoria d'ells s'utilitzen en targetes gràfiques de baixa potència-.

     The ball fan uses multiple steel balls as the medium to reduce friction, so it is characterized by high wind power, long service life, low noise, no lubricating oil and good heat dissipation performance. However, compared with ordinary fans, it will be more expensive in price
