1, cooling fan power is greater, the heat dissipation effect must be better

On the basis of the theoretical analysis, the cooling fan power is greater, the heat dissipation effect should be better, but this theory was established under certain preconditions, that is to say, in the operating power cooling fan does not exceed the approved sports power, cooling fan more power through wind often it is also more robust. The effect of heat dissipation is better. The sale of general computer on the market at present is DC 12V, power from O to 2 watts of power size range, which will need to choose according to CUP heating your theory is the choice of power, the larger is better, because the fan speed to spread the high. But I need to remind everyone here is not a one-sided emphasis on the high power, which requires power to the computer itself to match, if the power is too large, not only can not play a good cooling effect, but may work load will increase the computer, which will generate a vicious circle, and ultimately shorten CPU cooling fan life. We therefore users in the choice of CPU cooling fan, cooling fan can not simply think that the greater the power of its cooling effect will certainly be good, but should be according to the principle of heat radiation fan enough choice and their computer matching.

2, cooling fan fan of words can not be turned back

Many people would say cooling fan anti affirmation is not rotating, actually this kind of idea is very wrong, from the practical point of view, the clip of radiating fan even installed a meal, the cooling fan is also can run, but this kind of operation and can not achieve the effect of cooling, and a rotating time also do not have much time it will lead to improve system CPU temperature is prone to frequent crashes or automatic shutdown restart phenomenon. Therefore, I suggest that you install CPU, don't try to fan anti loaded, in order to avoid unnecessary losses.

3, cooling fan must reduce noise in accordance with the firm to

Just imagine, if the cooling fan is not firmly fixed on the radiating fin, but rather lax, so that the cooling fan will produce what kind of phenomenon in the process of high-speed rotation.? A lot of people will definitely blurted out: cooling fan is sure to produce a very strong noise; in fact this is very one-sided, although currently on the market a lot of cooling fan are the very firmly fixed on the radiating fin, but also some of the fan is not directly fixed to the heat sink, but fixed in a plastic frame on the. As we all know, one of the sources of noise of cooling fan is caused by the resonance, in order to reduce the causes of noise, a lot of cooling fan are fixed through a flexible plastic frame, so as to be able to prevent resonance effect. This cooling fan after directly fixed to the plastic frame, then put the plastic pardon through the buckles are fixed to the heat sink, gently press the cooling fan four corner, you will find the movement of space cooling fan has a certain room, do not ice is fixed not Rao, special design but in order to reduce the operation of the fan the noise went. So that the fan can reduce the noise around the test must be in accordance with the claim is biased!

4, the greater the heat sink gluten cooling fan cooling effect is better

Generated by CPU when the work of the heat by conduction to the heat sink, and then through the fan brought cold air blows the heat sink and put away, and the cooling fan can heat conduction and heat sink and how much the size of the. In general, the contact area and the heat radiating fins and the air and the bigger the radiation effect of the radiating fan is better, but this is a prerequisite, that is the chassis has enough free space case. If the computer chassis itself heat dissipation space is not large, there is not enough space left on the area of heat sink, very is difficult to follow to the auspicious, even if can be mounted to the chassis, the hot air contact area is too large will stop around the heat sink quickly, resulting in the overall internal chassis temperature too high and operation performance that affect the whole computer, so I suggest choosing the size of the heat sink area should be and chassis to match, can not blindly pursue area of large heat sink.
