CPU Heat Sink

Generally speaking, 30% of the heat dissipation effect of a radiator depends on the speed of the fan, but the higher the speed of the fan, the better. The correct fan speed should be determined based on the heat output of the CPU, and the selection of fan speeds for different specifications should be distinguished. The basic principle is that under the premise of producing the same air volume, the higher the fan speed, the lower the noise. Generally, the speed between 3500 to 5200 rpm is relatively conventional.
The higher the power, the stronger the wind force of the fan, and the better the heat dissipation effect. The power of the fan is directly related to the speed of the fan, which means that the higher the speed of the fan, the stronger and more powerful the fan. At present, the fans sold in the general computer market are DC 12V, with power ranging from 0.XW to 2.XW. Therefore, the size of power needs to be selected based on your CPU's heating capacity. A special reminder to everyone is that we cannot unilaterally emphasize high power, only need to match the power of the CPU itself. If the power is too high, not only does the cooling effect not improve much, but it may also increase the workload of the computer and ultimately shorten the lifespan of the CPU and fan. Therefore, when choosing the size of CPU power, it should be done with a focus on "heat".
A good radiator with no burrs on the edges, no deformation of the fins, smooth bottom without cracks, neat appearance, generous design, warranty, anti-counterfeiting logo or other trademark features.
