University of small fan ask CPU cooling fan Angle and bearing system

CPU fan is also known as a cooling fan is a kind of used to CPU cooling fan, should provide the radiator and applied case, is to apply them quickly to CPU heat conduction and blow into the full air, cooling effect. Cooling effect is good or bad is directly related to the quality of the CPU cooling fan, radiator. Fan is the main performance performance from the following several aspects: speed, leaf shape, fan leaf Angle of CPU fan and bearing system general situation, clarify the book indicated in the radiator fan speed. For ordinary radiator cooling effect with 30% depends on the speed of the fan. But the fan is not speed, the higher the better. Right fan speed resolution should be based on the calorific value of CPU, different specifications of the fan speed choice should distinguish somewhat, fundamental criterion is: on the premise of produce the same volume, the fan speed should be lower, the greater the noise will also small, regular in 3500 RPM to 5200 RPM speed is compared between the conventional. The greater the power, fan the strong wind, cooling effect is better. And the power of fan and fan speed and have direct contact, that is to say, the higher the speed of the fan, the fan will be strong. Big fan of local computer market sell is dc 12 v, the power is from 0. W to 5 X. 04 w, then the size of the power demand on the basis of your CPU calorific value to choose. Special remind everybody is, cannot the one-sided emphasis on power, only match the CPU itself the power to demand can be, if the power is too large, cooling effect is not much, not only may enhance the computer instead of working load, eventually shorten the life of the CPU breeze fan. Thus, when choosing the size of the CPU power at the same time, the amount should be 'hot'. Good radiator, the edge will not render burr phenomenon, no deformation, no cracks at the bottom of the lubrication cooling fins, neat, generous appearance, quality assurance, anti-counterfeiting marks or other features of the trademark, etc. In addition, we also pay attention to when choosing radiator is not too thick on the bottom of the radiator, due to the thermal conductivity of the aluminum is not very good, is too thick will affect heat transfer; Some additional radiator exterior grooves should close, thus to ensure that the radiator can have larger contact area with air, so as to strengthen the cooling effect.
