Does The Cpu Come With Thermal Paste?

In the world of computer building, it’s important to have a basic knowledge about the components involved. One such component is the CPU or Central Processing Unit. It is responsible for executing and coordinating instructions sent by other computer components. When building a PC, beginners often wonder about the need for thermal paste and whether or not it is included in the CPU package.

The short answer is that it depends on the type of CPU you purchase. Some CPUs, especially those that come with a stock cooler, may already have pre-applied thermal paste on the cooler’s surface. However, most modern processors do not come with pre-applied thermal paste, which means you’ll need to purchase and apply it yourself. In this article, we’ll explore in detail the importance of thermal paste and how to apply it if your CPU didn’t come with it.

Does the CPU Come with Thermal Paste?

When you purchase a new CPU, it may or may not come with thermal paste included. The thermal paste is a heat-conductive material that is applied between the CPU and the heat sink to improve thermal conductivity and prevent overheating. Below are some factors that may determine whether a CPU comes with thermal paste or not:

– Retail box or OEM: Retail box CPUs usually come with a box full of accessories, including a heat sink and a tube of thermal paste. OEM CPUs, on the other hand, are sold without any retail packaging and may not include any extra components, including thermal paste.
– Processor type: Some processor types, such as Intel’s boxed processors, are specifically designed to be sold with a complete cooling solution that includes a heat sink and a thermal interface material (TIM) pre-applied onto the heat sink. Other processors like AMD’s OEM CPUs may not come with any cooling solution or thermal paste.
– Availability and shipping restrictions: Depending on your location and the store you purchase your CPU from, you may find variations in what is included in the box. Some countries may have restrictions on the sale and shipping of thermal paste due to safety concerns, which may affect the availability of thermal paste inside the CPU box.

In summary, while some CPUs may come with thermal paste included, others may not. Therefore, it is always wise to check the package contents before buying a new CPU and to ensure that you have a sufficient amount of thermal paste to apply between your CPU and heat sink.


1. Does the CPU come with thermal paste?
Answer: It depends on the CPU model and manufacturer. Some CPUs come with pre-applied thermal paste, while others require separate purchase and application of thermal paste.

2. Is it necessary to apply thermal paste before installing a CPU?
Answer: Yes, thermal paste is essential to fill the microscopic gaps between the CPU and its heatsink, ensuring optimal heat transfer and preventing overheating.

3. How much thermal paste should be applied on a CPU?
Answer: A pea-sized amount of thermal paste is sufficient to cover the surface area of the CPU. Over-application of thermal paste can actually hinder heat transfer and cause more harm than good.

4. Can I reuse thermal paste once it has been applied?
Answer: It is not recommended to reuse thermal paste, as it tends to dry out and lose its effectiveness over time. It is best to use fresh thermal paste whenever reinstalling or upgrading a CPU.

5. What type of thermal paste should I use for my CPU?
Answer: There are various types of thermal paste available, including silicone-based, metal-based, and ceramic-based formulations. It is recommended to use a high-quality thermal paste specifically designed for use with CPUs, such as Arctic MX-4 or Noctua NT-H1.


In summary, while some CPUs might come with thermal paste pre-applied, it is not always the case. It is advised to check the specifications of your chosen CPU beforehand so that you can purchase the necessary thermal paste separately. Applying thermal paste correctly is vital to ensure optimal performance and to prevent any potential damage to your CPU. So, If you’re planning to build a PC or upgrade your current one, make sure to take care of the thermal paste application.
