The Importance of Thermal Paste

Thermal paste, also known as thermal compound or thermal grease, plays a crucial role in the cooling of a CPU (Central Processing Unit). It is a conductive substance that is applied between the CPU and the heatsink to improve the transfer of heat from the CPU to the cooler. The primary purpose of thermal paste is to fill in the microscopic imperfections in the contact surface, ensuring optimal thermal conductivity and reducing the risk of overheating.

But the question remains: is thermal paste included with the CPU when you purchase it? Let's explore this topic further to gain a better understanding.

OEM CPU Packages

When you purchase a CPU directly from the original equipment manufacturer (OEM) or as part of a complete system, it typically comes with thermal paste pre-applied. This is commonly found with retail boxed CPUs, where the CPU is packaged, along with an aftermarket cooler that already has thermal paste applied to its base.

Manufacturers apply the thermal paste to the cooler base during the production process for convenience and to ensure proper installation. As a consumer, you can rest assured that you have everything you need to install the CPU and cooler correctly without purchasing additional thermal paste separately.

However, it is essential to note that the pre-applied thermal paste may not always be of the highest quality. Enthusiasts and overclockers often prefer to use aftermarket thermal paste options for better cooling performance.

Retail CPU Packages

In contrast to OEM CPU packages, retail versions often do not come with thermal paste pre-applied. Retail CPUs are sold separately from the CPU cooler, giving users the flexibility to choose their own cooling solution. As a result, these CPUs usually do not include thermal paste as part of the package.

If you are purchasing a retail CPU, you will need to buy thermal paste separately. It is important to choose a high-quality thermal paste to ensure optimal heat transfer and cooling performance. There are many reputable brands in the market, offering a wide range of thermal pastes with varying levels of thermal conductivity and application methods.

When applying thermal paste to a retail CPU, it is crucial to use the right amount. Applying too much can lead to an excessive layer of thermal paste, hindering heat transfer. On the other hand, applying too little may result in poor thermal conductivity. It is recommended to follow the manufacturer's guidelines or consult online resources for proper application techniques.

Reapplying Thermal Paste

Over time, the thermal paste between the CPU and the cooler may degrade, dry out, or become less effective due to air exposure. This can result in increased CPU temperatures and reduced cooling performance.

If you are noticing higher CPU temperatures or experiencing thermal throttling, it may be time to reapply thermal paste. In such cases, regardless of whether thermal paste was initially included with the CPU or not, you will need to purchase thermal paste separately to ensure proper cooling and heat dissipation.

Always clean the old thermal paste from the CPU and cooler using isopropyl alcohol before applying a fresh layer. This ensures a clean and even surface for optimal thermal conductivity.
