How to Apply Thermal Paste to Your CPU?

So you’ve decided to take the plunge and build your own gaming PC. Congratulations! Not only will you get to enjoy the satisfaction of knowing that you built your rig with your own two hands, but you’ll also save a ton of money in the process. However, before you can start gaming, there’s one more task that needs to be completed: applying thermal paste to your CPU.

Don’t worry, it’s not as difficult as it sounds. In this article, we’ll walk you through the entire process step-by-step so that you can get up and running in no time. Let’s get started!

How to Put Thermal Paste on CPU?

Applying the thermal paste to your CPU may seem like a daunting task, but it’s actually quite simple. Let’s go!

Step 1: Clean the Surface of Your CPU and Cooler Fan Blade

The first step is to make sure that both the surface of your CPU and the cooler fan blade are clean. Any dirt or dust on either of these surfaces can impede heat transfer, so it’s important to make sure they’re both pristine before proceeding. The best way to do this is to use a can of compressed air to blow away any dust or debris. Once you’re finished, give both surfaces a quick once-over with a lint-free cloth just to be safe.

Step 2: Apply Thermal Paste to Your CPU Cooler Blade

Next, it’s time to apply thermal paste to your CPU cooler blade. Most thermal pastes come with a small spatula or spreader that makes this task a breeze. Simply spoon out a pea-sized amount of thermal paste onto the center of the cooler blade, then use the spatula or spreader to spread it out into an even layer. Be careful not to apply too much paste; a little goes a long way here. If you find that you’ve applied too much, simply remove some with the edge of the spatula or spreader before moving on to the next step.

Once you’ve applied an even layer of thermal paste, carefully lower the cooler blade onto your CPU until it makes contact with all four corners of the chip. You should now have a nice, even layer of thermal paste between your CPU and its cooler blade. Congratulations—you’re now one step closer to having a fully functioning gaming PC!

Step 3: Reassemble Your PC and Test It Out

The final step is to reassemble your PC and fire it up for a test run. If everything goes according to plan, you should now be able to enjoy crisp, lag-free gaming at high frame rates—all thanks to that thermal paste you so expertly applied!CPUs can generate a lot of heat when they’re under heavy load, so it’s important that they have adequate cooling in order to function properly. That’s where thermal paste comes in; by filling in the microscopic imperfections on the surface of your CPU and cooler fan blade, it creates a smooth surface that promotes efficient heat transfer between the two components. As a result, your CPU will run cooler and perform better overall.

thermal paste is essential for any gaming PC build—so if you’re planning on putting together your own rig, make sure you pick up a tube before getting started! Trust us, your future self will thank you for it.

Does Thermal Paste Go on Top or Bottom?

Applying thermal paste is not as simple as it sounds. In order to ensure that your CPU performs at its best, you must apply the thermal paste correctly. If you don’t, you run the risk of damaging your CPU and voiding your warranty.

There are two schools of thought when it comes to applying thermal paste. The first school of thought says that you should apply the thermal paste to the top of the CPU. The logic behind this is that the heat from the CPU will spread evenly across the surface of the thermal paste.

The second school of thought says that you should apply the thermal paste to the bottom of the CPU. The logic behind this is that the heat from the CPU will travel up through the thermal paste and be dissipated more efficiently.

So, which school of thought is correct? The answer is that it depends on your particular CPU and how it is designed. If you have a CPU with a heat spreader, then you should apply the thermal paste to the bottom of the CPU. If you have a CPU without a heat spreader, then you should apply the thermal paste to the top of the CPU.

Either way, the important thing is to make sure that you apply a thin layer of thermal paste to the surface of the CPU. You don’t want to glob on a thick layer of thermal paste, as this will actually insulate the heat rather than dissipate it.

Once you’ve applied the thermal paste, you can then install the CPU cooler. Make sure that you follow the instructions that come with your particular CPU cooler, as some coolers require a different installation process than others.

And that’s all there is to it!


Applying thermal paste may seem daunting at first, but trust us—it’s easy! Just follow these simple steps and you’ll have no trouble at all. Now go forth and play like never before!
