How to Apply Thermal Paste on CPU

Do you know how to Apply Thermal Paste on CPU? The fact that thermal paste can be applied in a variety of ways is one of the reasons why some enthusiasts find the topic contentious. Everyone has their own technique for applying paste in order to achieve the best results; however, in my experience, the best temperatures come from using the simplest and most often minimalist application method—just one dot.

The “grain of rice” method is another name for this particular approach. There are some newer exceptions to this rule, such as larger CPUs needing more paste to cover the large surface area or hitting specific hotspots under the heatspreader, but the general recommendation is still the same: just a tiny bit of paste goes a long way.

It is helpful to have an understanding of some of the issues that can occur with various application processes before going on to discuss the method of application that I personally prefer. One of the most typical approaches taken is one that is frequently known as the “line method.” This is exactly how it appears to be. Apply a very thin line of thermal paste directly down the middle of the IHS (Integrated Heat Spreader), and then allow the pressure of the CPU cooler to spread the paste out while you secure it in place. here are the ways how to Apply Thermal Paste on CPU.

What Is Thermal Paste?

Before we can get into the specifics of this topic, it is probably a good idea to elaborate on what it is and why central processing units require a paste of this kind in the first place. To achieve the highest possible level of thermal conductivity, a compound known as thermal paste, which is a mix of various materials, is used. If you want to improve the contact between the heatsink (your cooler) and the heat source (your processor), you will need this incredible thermally conductive compound.

However, why? Why not just hook up the cooler to the central processing unit (CPU), and then get to work, play games, or do whatever else you want to do? Simply put, this is because it is difficult to make effective contact between two surfaces that are both extremely level. Both the chilly slab (a metallic slab) on the refrigeration device and the IHS (the heat spreader on the processor) have defects. The chilly slab is the metal slab. Each of the surfaces contains numerous minute cracks, crevices, corners, and gaps. These two things can create a stronger physical link by filling those openings with a thermal substance, which will result in an increase in the amount of heat that is scattered.

How to Apply Thermal Paste on CPU

1. Turn off your PC and unplug the power cord. Open the case.
2. Prepare your cooling system for installation. Install any mounting hardware such as backplates or brackets.
3. Clean the metal top of the CPU, including the Integrated Heat Spreader (IHS) and the part of the cooler that contacts it. Use a microfiber cloth and isopropyl alcohol to ensure a clean surface. Ensure everything is dry afterward.
4. If not already done, place your PC on a flat surface with the CPU facing up.
5. Begin applying thermal paste. For a square CPU, apply a small dot at the center of the IHS, no larger than a few millimeters. For a long CPU, consider using two or three dots with a thin line between them, although it’s safer to use two dots.
6. Set up the cooling system ensuring proper alignment initially to avoid twisting during installation, which could cause the paste to spread unevenly.
7. Verify that the thermal paste does not extend beyond the edges of the IHS without running off the sides to ensure correct application.

The Importance of Thermal Paste for CPU Cooling

1. Heat Transfer: By filling in tiny gaps and rough spots on the surfaces, thermal paste makes it easier for heat to move from the CPU to the cooling system. This makes it easier for heat to escape.
2. Getting Rid of Air Pockets: Putting thermal paste on the CPU and cooling device helps get rid of air pockets that can form between them. Since air doesn’t conduct heat well, getting rid of these pockets makes thermal conductivity better.
3. Even Heat Distribution: It makes sure that heat is spread evenly across the CPU’s Integrated Heat Spreader (IHS), which stops hotspots that can hurt performance and lifespan.
4. Stopping Overheating: If you don’t use the right thermal paste, the heat transfer between the CPU and the cooling solution might not work as well, which could cause the computer to get too hot. If the processor gets too hot, its performance may slow down and it may even be damaged in the long term.
5. Long-Term Stability: The constant heating and cooling can knock the CPU and the cooling device out of place over time. Thermal paste makes things stable by filling in gaps and making sure there is constant thermal contact.
6. Improving Efficiency: Using thermal paste correctly makes sure that the cooling system can work at its best, keeping temperatures low and letting the CPU run at its best.

Materials Needed for Applying Thermal Paste

Tips for Achieving Optimal Thermal Paste Application

1. Clean Surfaces: Before applying thermal paste, make sure both the Integrated Heat Spreader (IHS) of the CPU and the corresponding part of the cooler are clean. Use a microfiber cloth and isopropyl alcohol to remove any residue.
2. Amount Matters: Use an appropriate amount of thermal paste. For a square CPU, a small dot at the center of the IHS is usually sufficient. For longer CPUs, consider using two dots or a thin line between them. Overapplication can be as detrimental as underapplication, so strike a balance.
3. Avoid Spreading: Let the pressure from the cooler spread the thermal paste naturally. Avoid manually spreading the paste as this can lead to uneven coverage.
4. Proper Alignment: When installing the cooling system, ensure it’s correctly aligned from the start. This minimizes the need to twist it into place, preventing uneven spreading of the thermal paste.
5. Flat Surface: Place your PC on a flat surface during installation to ensure proper contact between the CPU and cooler.
6. Quality Paste: Invest in high-quality thermal paste. Conduct research or seek recommendations to choose a paste with good thermal conductivity for effective heat transfer.
7. Reapplication: If you ever need to reseat your cooler, clean off the old thermal p
