AMD Ryzen series processors offer more cost-effective options for users. The whole Ryzen series uses soldered heat dissipation design, which has better heat dissipation performance. CPU overclocking is much more powerful than silicone grease, which most people call This is a bona fide enterprise, and network has shown that ninth generation Intel Core processor will use soldering. I guess many users don't know what does CPU soldering mean? Let's popularize science of difference between CPU soldering and silicone grease.

What does CPU soldering mean?

As we all know, in order to protect internal core of CPU, CPU adds a metal top cover on top of CPU, mainly to prevent CPU heatsink from directly contacting CPU core, which is conducive to protecting CPU core. However, there will be a gap between CPU core and metal top cover. Generally, a thermal interface layer is added between CPU core and metal top cover, and this thermal interface can be silicone grease or solder.

Solder is a metal with a low melting point, which can also be called "liquid metal", and thermal conductivity of metal is undoubtedly much better than that of silicone grease. In addition, if thermal paste is used for a long time, temperature difference between cold and hot will cause it to gradually dry out and harden, resulting in a high CPU temperature and affecting life of CPU. The use of soldering is superior to silicone grease in terms of heat dissipation, but cost of soldering is also much higher than that of silicone grease.

All AMD Ryzen processors currently use soldering for heat dissipation, while 8th Generation and previous Core processors use silicon grease. I believe that Intel will use soldering for heat dissipation in ninth generation Core processors. Let's wait and see. Although these are high-performance Intel processors, many players prefer to open cap to replace liquid gold, but risk of damage to processor is relatively high, and you will not be able to use Intel's warranty later, please think carefully.

What's difference between CPU soldering and silicone grease?

The main difference between CPU soldering and silicone grease is use of different thermal materials. Silicone grease is a high thermal conductivity insulating silicone material, and soldering is a low melting point metal material. Through use of different dielectric materials, so heat dissipation effect is also different. The thermal conductivity of metal is much higher than that of silicone grease, so heat dissipation efficiency is very high. The use of low melting point metals can completely solve problem of silicone grease hardening.

Soldering heat dissipation is not only a boon for overclockers, but ordinary users can intuitively feel power of soldering heat dissipation. I believe that Intel's new platform processors will soon switch to solder heat dissipation and say goodbye to legacy heat. dissipation "Silicone grease" dissipates heat. According to official information, in same working environment, CPU with soldering design can effectively reduce temperature by more than 10 ° C, compared with silicone-cooled CPU.
