When Do You Need to Apply Thermal Paste?
Thermal transfer material is used when installing any cooling solution. When people think about thermal paste in the context of building a PC, they’re probably referring to the process of installing a CPU cooler. When you buy a graphics card, for example, the thermal solution is already integrated. You don’t usually have to worry about installing a cooler onto a GPU, unless you are interested in aftermarket solutions like custom liquid cooling. With a CPU cooler, you have the option to choose the one you want, but that means you’ll usually need to install it yourself.
Terms You Need to Know
In order to properly explain how thermal paste functions, it’s worth defining some of the terms we will be using.
Central Processing Unit (CPU) - The information processing center of a PC. It executes all operational instructions and sends instructions to the other hardware in the computer. If the computer is a body, then the CPU is the brain, and it is absolutely critical to the functioning of any PC. Modern CPUs execute a high volume of operations per second, and this generates heat. In order for a CPU to operate at peak efficiency, it needs to be properly cooled, usually with a cooling apparatus designed just for this purpose. This is where thermal paste becomes important. If you'd like to learn more about how a CPU is made, you can read more about the manufacturing process.
Integrated Heat Spreader (IHS) - The metal “lid” of the CPU. This serves as a heat sink designed to distribute heat from the processor itself to a CPU cooler, as well as provide protection to the processor inside. This is the part of the CPU that is still exposed after being installed in a motherboard, and is the surface to which you apply thermal paste.
CPU Cooler - The device that keeps your CPU running at optimal temperatures. CPU coolers usually use air or liquid to relocate the heat created by the operation of the CPU.

Installing a Processor
The following sections describe the steps required to install and configure standard slotted and socketed processors. The steps we describe are generally applicable to any modern processor of a given type, but the details may vary slightly between different processors, particularly with regard to such things as configuring the motherboard and installing heatsink/fan units. If this is the first time you’ve installed a processor, or if you are in doubt about any step, refer to the documentation provided by the manufacturer of your specific processor
