What is cpu soldering? Popularization of processor lubricants and soldering knowledge
The ninth generation Core processor uses soldering to dissipate heat. What is soldering? What does soldering have to do with CPU cooling? Why is soldering better than silicone grease? Today I will share this little knowledge with you.
Don't look at size of CPU, its core is actually very small. Outside, CPU is top metal case cover. Only by opening top cover can real CPU core be seen. The function of top cover is to protect core, but after adding top cover, CPU core is in a closed state, and heat cannot be dissipated at all, so a substance is needed to connect CPU core and top cover. for heat dissipation, and medium used for heat conduction is usually silicone grease and soldering.
Solder is a metal with a very low melting point and can be called liquid metal, or liquid gold for short. The thermal conductivity of metal is very high, which is much better than silicone grease. solidify during use, which leads to a significant decrease in its thermal conductivity, while with liquid metal opposite is true.
Silicone grease is a silicone material with high thermal conductivity, while soldering is a metal with a low melting point. The advantage of metal in dissipating heat is much more obvious than that of silicone grease, and due to its low melting point, there will be no issue of solidification.
Right now, AMD Ryzen processors use soldering for heat dissipation, but eighth generation of Intel Core still uses silicone grease, but it is said that ninth generation will be replaced by soldering. The press conference will take place on August 8, and ninth generation Core may be released).
Currently, when using flagship Intel processors, many enthusiast gamers usually open processor cover and replace liquid gold themselves. However, this method is very risky. If you do not often do your own hands, it is better not to try. it's light. .
It's hard for general gamers to experience heat dissipation benefits of soldering, but for gamers who enjoy overclocking, soldering is a very powerful means of dissipating heat. heats up about 10 degrees Celsius lower than silicone grease.
