I believe many DIY players must have heard of "CPU exposure". Some amateur enthusiasts remove CPU cover and then replace built-in heat dissipating silicone grease with liquid gold (liquid metal) with better heat dissipation performance. Then restore previous view of processor. In past, there was an incident with Master Wang unlocking processor. As a result of unlocking processor, a valuable processor of several thousand or even 7.8 thousand was replaced by a processor of several hundred yuan. Encourages, so I advise everyone not to do this illegal and criminal things. So, what does it mean to open processor cover? What is use of opening CPU cover? The editor is designed to help users popularize basic knowledge of opening CPU.

What does it mean to open processor cover?

Opening CPU cover is nothing but opening top metal cover of CPU with CPU cover opener, mainly to replace silicone grease on plate with liquid gold, and further improve heat dissipation performance of CPU.

Why open CPU cover?

Unlocking processor is not for you to do illegal and criminal activities, to replace other people's high-performance processors with cheap ones in order to make huge profits.

Because current Intel processor uses silicon grease inside, its heat dissipation performance is not as good as soldering inside AMD Ryzen processor, so thermal conduction efficiency of processor is naturally much worse than soldering. Therefore, for high-performance processors, some homemade turntables need to replace silicone grease inside processor with liquid gold.

As we all know, CPU top metal cover is mainly to protect internal components, but there is still a certain distance between CPU main chip and top metal cover, and overall heat conduction effect. The silicone grease is definitely not as good as liquid metal (liquid metal) effect. When core chip is heated, liquid metal can better conduct heat to top cover to achieve better heat dissipation.

For example:

Generally speaking, only flagship processors that support overclocking can be opened. For example, K-enabled i7 series processors support overclocking. Currently, processor still uses silicone grease to conduct heat inside processor. We are overclocking processor. Sometimes, this will cause CPU temperature to rise dramatically. If heat dissipation cannot be satisfied, it may cause CPU to become unstable or crash, or even a very bad CPU. At this time, some players will open CPU cover and replace internal silicone grease with liquid metal and other media with better thermal conductivity, so as to improve heat dissipation performance of CPU and greatly reduce temperature of CPU.

Danger of opening processor cover

After opening cover, CPU will not be able to use Intel after-sales service, which means CPU is out of warranty. In addition, professional requirements for opening CPU cover are relatively high, and non-professionals will have a greater risk of opening cover. Because internal design of CPU is very complex, if you are not careful, CPU will be scrapped, so we do not recommend ordinary users to try CPU cover .

The above is general basic knowledge about CPU unlocking. I hope you can better understand benefits and dangers of CPU unlocking. Before unlocking CPU, you should study relevant knowledge to reduce risk of unlocking the CPU.
