The performance of the cooling fan.
Fan’s performance can be reflected from the following aspects: speed, fan leaf shape, blade, Angle and bearing system.In general, the radiator is marked on the manual of the speed for fan.Generally radiator cooling effect with 30% depends on the speed of the fan.But is not the higher speed more better.The right fan speed should be determined according to the CPU calorific value, different specifications of the fan speed choice should distinguish somewhat, the basic principle is: on the premise of produce the same volume, the fan speed should be lower,the noise may also be smaller, generally speed between 3500 RPM to 5200 RPM is more conventional.
The greater the power,the strong wind of fan, cooling effect is better.And the power of fan has a direct link with fan speed,that is to say, the higher the speed of the fan, the fan will be strong.On the general computer market at present selling fan is dc 12 v, power from 0 X W to 2 X W, so the size of the power will need to choose according to your CPU heat.Special remind is, cannot one-sided emphasis on power, only need to match with the power of CPU, if the power is too big, not much enhanced cooling effect, on the contrary may enhance the computer workload, shorten the life of the CPU in the end.Therefore, when choosing the size of the CPU power, at the same time should be with the correct “hot”.
Good radiator, edge there will be no burr phenomenon, the cooling fins no deformation, no cracks at the bottom but smooth, clean and tidy appearance,elegant style, quality assurance, anti-counterfeiting marks or trademark with other features,etc.In addition, we also need notice when choosing radiator is can not too thick on the bottom of the radiator, because of the thermal conductivity of the aluminum is not very good, if too thick will affect heat transfer;Additional grooves on the surface of the radiator should closer, this will ensure that the radiator can have larger contact area with air, so as to enhance the cooling effect.
