How to Delid an Intel Core i7 8700K in Easy Steps

how to delid Coffee Lake 8700K CPU

There are a lot of reports on different forums regarding the thermal issues associated with the Intel Core i7 8700K Cofee Lake CPU. Even if you don’t overclock this CPU, you can witness unusual temperatures while playing games or multitasking. By research, it has been found that the main culprit behind this is the stock thermal paste installed by Intel. Therefore, to overcome the thermal issues, you have to delid your Intel 8700K CPU. Also, if you are a performance enthusiast, it is worth replacing your stock thermal paste with a high-quality one.

Delidding is the process of removing the IHS (Integrated heat spreader) from your CPU and then replacing the stock thermal paste with a premium one. A few years back delidding was done with blades and thin metals exposing risk to a CPU. Over time, things have changed and now you can find safe equipment to delid your CPU. The core advantage of delidding a CPU is to achieve higher clock speeds while maintaining the lowest temperatures.

Keep in mind that the CPU delid only applies to Intel processors. And in this guide, we will talk about how to delid your i7 8700K CPU in simple steps. However, before delidding your CPU, it’s important to know how your CPU is built. So, let us discuss the most important parts of a CPU and then carry on with the delidding process.


The PCB is the part of the CPU that houses all the circuits and connects them to the main socket on the motherboard.


This is the part where you will find the actual processor with its multiple cores and threads. Also, this section is responsible for the heat output. Keep in mind that, the CPU Die is extremely fragile and cannot be removed as it is soldered to the circuit board.

Thermal Paste Layer

The thermal paste at the top of the CPU die and acts as a thermal medium between CPU Die and IHS. It is because of this paste your CPU cools and transfers heat from Die to IHS.

IHS (Integrated Heat Spreader)

The integrated heat spreader or IHS serves as a thermal connection between the CPU Die and the CPU cooler that sits on top of the IHS.

Because of the thermal paster/layer between CPU Die and IHS we can easily delid Intel CPUs.

Here’s the process to follow:

Removing the Metal Cover Using CPU Delid Tool

This is one of the most inexpensive and easy methods to reapply thermal paste on your 8700K processor.

  • Place your processor inside the CPU delid tool and rotate the screw to open the lid. The glue on the top will eventually leave its place and now you can easily open the CPU. It’s that simple! However, keep in mind that delidding your processor will void its warranty so be careful in doing this.

Cleaning and Reapplying Thermal Solution

Once you have removed the top metal part of the CPU, it’s time to clean the existing junk under the IHS.

  • Clean the die and part beneath the metal plate.
  • Also, clean the existing thermal solution between the Die and IHS.
  • Apply a grain of new thermal solution, make sure it does not exceed the rectangular edges.
  • Once you are done with the thermal liquid, it’s time to reapply the high temperature silicone glue to the rounded corners of the metal plate.
  • Place back the metal plate on the top of the CPU and put it back in the delid tool. Make sure to apply pressure using the delid tool for 30 minutes.
  • Remember to reapply the thermal paste on the IHS before placing the CPU cooler.


Finally, delidding your Intel Core i7 8700K can significantly improve its thermal performance and can give you more edge in overclocking it. By using the proper equipment you can easily take off the top cover of the CPU and then clean the existing thermal solution using a fiber cloth.

Keep in mind that it’s a risky thing to do if you don’t know anything about computers. In that case, you can get help from a computer professional or a friend who knows about assembling or disassembling computer parts.
