Is the CPU going hot? Look at these points first when changing the radiator!
Is copper better than aluminum? not that simple!
The material of the CPU radiator is mainly copper and aluminum. Because of the specific heat capacity and density of metal, copper absorbs heat and conducts heat quickly, but it also heats up quickly. Aluminum is just the opposite, so I can't say which one is better. The radiator of the high-frequency processor combines their advantages. It uses a copper core on the bottom and an aluminum fin design. The effect is very good and it is worth choosing.
The wind direction varies, how should I choose?
There are two fan designs for the CPU radiator. One is the traditional downward blowing method, which blows directly on the bottom surface of the radiator and has a more compact structure. The side blowing method is that the fan is on the side of the radiator. Larger fans and multiple fans can be used, but the heat must be quickly transferred to the fins. Generally, multiple heat pipes are used, which is costly and takes up a lot of space.
The choice of down blowing or side blowing mainly depends on the design of the chassis and air ducts. There is no choice for a small chassis, and direct blowing can be used to install it. The large chassis can be installed with side blowing, and the blowing direction should match the air path of the chassis as much as possible. After a good air duct is formed, it can also help the memory and the power supply unit to dissipate heat.
When choosing a CPU cooler, you should also pay attention to the size. If it is too large, it will press down on the memory slot. Some coolers will be made into a "floating" shape to leave room for memory. However, only general memory modules can be installed below, with larger ones. The memory of the heat sink is still choking. Also pay attention to the height of the radiator that the chassis can hold. It would be embarrassing if the back cover of the radiator does not fit on the case cover.
Heat pipe radiator, don’t just look at the quantity
In fact, the thermal conductivity of generally 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 influence on the heat dissipation effect is actually whether the heat pipe can quickly receive heat from the bottom surface. This is related to the contact method of the heat pipe. The direct contact heat pipe is the best choice. It directly contacts the surface of the CPU and conducts heat more directly and quickly. The heat pipes of the method have been "shaped" or even polished, and they are relatively fragile. Do not disassemble or assemble it just as it is fine.
