Radiator part
The current radiators are mainly air-cooled and water-cooled, of which air-cooled is mainly divided into down-pressure type and tower type, and water-cooled is divided into integral type and split type. Regardless of whether it is air-cooled or water-cooled, the heat dissipation principle is similar. They all use metal parts (air-cooled heat pipe copper pillars or aluminum blocks, water-cooled cold head) to close to the CPU, and then the heat generated by the CPU can be conducted through this part of the metal. After that, the heat conduction part (air-cooled aluminum sheet, water-cooled water pipe) is dispersed and conducted, and finally the hot air is blown out of the chassis by a fan. Therefore, to compare the heat dissipation ability of heat dissipation is mainly to compare the heat conduction part and the fan part on heat dissipation. The higher the heat conduction efficiency, the more violent the fan. In principle, the stronger the heat dissipation. Let's talk about it in several categories below.
Just as the CPU and graphics card are determined for installation, the requirements must also be determined when determining the heat sink. First, how do you use the whole machine, then how do you define the high temperature, and secondly, do you have any need for silence. Especially when it comes to Ryzen5 2600(x) i7-8700(k) and higher radiator levels, are you just for daily entertainment, playing games or designing professional work such as graphics computing rendering, taking 8700 as an example, many people think T400i can be suppressed, but in fact, if you do professional work for a long time, it is difficult to use T400i to suppress the 8700 without frequency reduction. It doesn't matter just playing lol. In addition, what is high temperature for you, some people can say that it can be suppressed if the temperature of the CPU and graphics card is controlled below 100, while many people have no sense of security when the temperature exceeds 60 or 70 degrees. Both of these require radiators. are different. Finally, the problem of silence is also a problem of user experience. The pursuit of better heat dissipation generally requires a higher-speed fan, which is likely to bring more noise. Then your acceptance range should also be considered, so there is also a joke. It is said that noise-cancelling headphones can greatly improve the performance of the host. Anyway, if you wear the headphones and can't hear it, then the fan can turn vigorously.
The simple way to judge the specifications of the radiator is to look at the design power of the radiator in the product introduction (some users can only ask the netizen if you don't write it in the introduction), that is, how much power consumption is the CPU designed for this radiator, and then according to The CPU power consumption you choose determines the appropriate heat sink. The way to judge whether the radiator and other components match the chassis is to look at the properties of the chassis. The figure below is the data of a cooler chassis. To match this chassis, you only need to choose the motherboard (matx and itx) with specifications below ATX. The air-cooled graphics card below 165 and the length of less than 410mm are fine.
Chassis fan section
Speaking of the chassis fan, you have to mention the chassis air duct, as shown in the picture is the introduction diagram of Enjie H500, this picture can explain what the normal air duct is. The hot air rises under natural conditions, so the way to exhaust the hot air is to exhaust the heat in the chassis from the top and the rear of the chassis, that is to say, the front panel and bottom of the chassis enter the air, and then the top and back exhaust air. Generally, the front and the top can be equipped with a fan or a cold row, the rear is mainly a fan, and the air intake below is mainly a fan of the power supply (some cases also support a lower fan position) and a graphics card fan (the graphics card is beautiful but actually not conducive to it. The air duct is constructed, and the vertical stability is not good, and it is not suitable to be moved frequently). As for the tower-type heat dissipation mentioned above, which is beneficial to the air duct, it can be seen from the second figure that after the tower-type radiator is installed in the chassis, it will follow the overall air inlet and outlet.
The main point of choosing a fan is to look at the size of the fan and the choice of fan performance provided by netizens. See clearly what size fans are supported by each part of the chassis (usually 120 or 140mm fans, some itx chassis will be smaller). You can even replace the tower radiator with a fan with better performance if you need it. For example, many air-cooled fans can be disassembled. If you ask the customer service for compatibility in advance, you can buy a fan and replace it with the radiator. Finally, don't install the fan backwards. If you install it backwards, the heat dissipation will be worse. It's better not to install it. The most stupid way is to simply connect some and feel which section is the air outlet. The easiest way is to look at the fan blades. Concave and convex, convex in and concave out.
