In fact, the graphics card temperature is generally the highest temperature in the entire chassis, standby or conventional 50-70 ℃ (or lower), run a large 3D game or play high-definition video, the temperature can be as high as 90 ℃ or so, the general high load under no more than 100 ℃ are considered normal category. If necessary, the fan speed can be adjusted to the appropriate height. In other words, the normal temperature of the graphics card is normal within 90°. We do not have to worry about such a high video card temperature will burn out the graphics card, the graphics card in the production factory are after the strict temperature test, the manufacturers can be at ease to the graphics card affixed to the certificate, as consumers of our trust manufacturers.
Above is the desktop computer graphics card, notebook graphics card normal temperature is higher than the desktop.
Notebook video card Cooling problem is more serious, this is due to some problems in the notebook design structure caused. Although there are many notebooks that support single and set switching, but in running some of the larger game, the graphics card temperature will obviously rise, and the temperature of the notebook video card is 120 degrees, the warning temperature is 90 degrees, usually think that the normal notebook video card temperature within 80 degrees is normal, full load should be around 85 degrees , if the job is not too normal, you may need to strengthen the heat dissipation, or remove dust.
Here is a reference to some test data to illustrate the normal temperature of the mainstream graphics card.
One, the first 40nm process to make the mainstream of the introduction of graphics card HD4750 as an example. Temperature test results for standby for 42 degrees, full load of 70 degrees, combined with the radiator to see. The pure radiation radiator +PWM The low speed intelligent high speed fan, other such temperature already is OK, already this kind of radiator to deal with the 40nm craft production HD4750 already is very enough.
Second, the main graphics, test object: 9800GT. The idle temperature is 40 and the full load temperature is 69.
In fact, this 9800GT and just HD4750 temperature control situation is similar, but in the radiator aspect, 9800GT more advantages, but based on 55nm process G92 core 9800GT in the thermal aspect is a bit large. Large-area thermal card is the key to this radiator, it is with the 8CM PWM fan very well with, and then can be pressed to the temperature of 70 degrees below.
Third, the middle-end high graphics card, test object: HD5830
1, four heat pipe + copper Bottom radiator test results: Standby 27 degrees, full load 64 degrees
2, double heat pipe + copper Bottom radiator test results: Standby 25 degrees, full load 85 degrees
Obviously from the temperature test results can be seen, the four heat pipe + copper Bottom radiator has an absolute advantage, than the temperature of the double heat pipe is about 20 lower. However, we do not think that said, buy a double heat pipe version of the HD5830 said this temperature problem, the other this temperature is not a problem, but the heat is not strong enough, the temperature will not have a great impact on performance.
