What factors influence the performance of CPU Thermal Heatsink
Many people are worrying about the thermal performance of computers in summer, and the CPU temperature is even more serious. And plan to update a stronger heatsink module. How to choose a suitable radiator and what should be paid attention to?
Copper is better than aluminum?
CPU heatsinks are mainly made of copper and aluminum. Because of the specific heat capacity and density of metals, copper absorbs heat quickly and conducts heat quickly, but the temperature rises quickly. Aluminum is just the opposite, so it can't be said which is better. The radiator of high-frequency processor combines their advantages and uses the design of bottom copper core and aluminum cooling fins. The effect is very good and worth choosing.
How to choose the air flow direction and volume:
Usually ,There are two fan designs for CPU radiator. One is the traditional downward blowing method, which directly blows the bottom of the radiator, making the structure more compact. The side blowing method is that the fan is on the side of the radiator, and larger fans and multiple fans can be used. However, it must be ensured that the heat is quickly transmitted to the fins. Generally, the multi heat pipe method is adopted, which has high cost and takes up a lot of space.
The selection of down blowing or side blowing mainly depends on the design of chassis and air duct. There is no choice for small chassis, and direct blowing can be installed. The side blowing mode can be installed on the large chassis. The blowing direction should match the chassis air path as much as possible. After forming a good air duct, it can also help heat the memory and power supply unit. We also need to consider the size when selecting the CPU heatsink. If it is too large, it will press the memory slot. Some heatsink design will be made into a "suspended" shape to leave space for the memory. In addition, pay attention to the height of the radiator that the chassis can accommodate.
More heatpipes, better thermal performance?
In fact, the thermal conductivity of three or four heat pipes can cope with the heat of high-end processors, so there is no need to pursue a particularly large number of heat pipes. The most obvious effect on heat dissipation is whether the heat pipe can quickly receive heat from the bottom, which is related to the contact mode of the heat pipe. The direct contact heat pipe is the best choice. It directly contacts the CPU surface and conducts heat more directly and quickly.
When choosing the heatsink cooler for your electric device, many factors need to be considered. And we can also have DIY customized heatsink cooler, all the speciafication can be re-design.
