Four basic components: display card radiator fan, heat pipe, copper bottom, fin. Each video card manufacturers display card radiator design are not the same, different appearance, different materials, fan blades of different, different specifications of brass, radiator fin design, welding process and so on have different heat capacity are not always the same. On the surface, it is difficult to judge the heat capacity of the two graphics cards.
In fact, all cannot do without a reason. The importance of this is the component of knowledge, such as fan is used to provide airflow, diameter of the fan like, three fans will more than a air flow of the fan, the heat pipe is used to heat conduction, if the heat pipe with the same diameter, 5 root heat pipe heat conducting certain than 2 heat pipe faster, the fin is used to are heat and cooling, the fin surface area is larger, so surface in contact with the air and the greater, natural cooling effect better. In fact, only with the eye and picture to determine the heat dissipation capacity of graphics cards, it is these.
The common fan is divided into two, one is the public version of the card has a soft spot for a turbofan, the public version of the NVIDIA and AMD graphics like turbine fan, seems to have become the a habit or can be said to be faith. Another is custom-built card is the most common fan fan shaft.
Turbo fan is a centrifugal principle (do not deliberately to understand, the advantage is to provide airflow at the same time ensure outlet pressure, more penetrating power, but the fan must to design special diversion shell, let display card radiator formed inside a similar closed air flow loop, wind from the fans into, hot air from the graphics card baffle, will not cause serious accumulation of heat. The disadvantage is that the high speed air, noise is also very obvious, therefore the public version of the graphics card fan pull over tend to hear annoying noise.
