2. Using Thermal Paste Cleaners

Keeping your CPU running at optimal temperatures is crucial for maintaining its performance and prolonging lifespan.

One way to achieve this is by using thermal paste, a heat-conductive material that fills the microscopic gaps between the CPU and its cooling solution.

However, the thermal paste can dry out or become contaminated over time, reducing its effectiveness. Below we will discuss using thermal paste cleaners to remove the old paste and prepare your CPU for new applications.

Step 1: Gather the Required Materials

Before you begin, ensure you have all the necessary materials. You’ll need thermal paste cleaner, which can be purchased online or from your local computer store. We recommend using a high-quality cleaner that is safe for use with CPUs and has good reviews. You’ll also need a pair of Q-tips, a magnifying lens (if necessary), and a clean, dry cloth.

Step 2: Apply the Thermal Paste Cleaner

Using a Q-tip, apply a small amount of the cleaner to the affected CPU areas. Be careful not to use too much; starting with a modest quantity and adding more as needed is better. Let the cleaner sit on the CPU for at least 5 minutes to allow it to bond with the paste.

Step 3: Clean the CPU Pins

Using a clean Q-tip, gently brush the CPU pins to remove any excess paste. Be careful not to apply too much pressure or scrub too vigorously, especially if cleaning the popular AMD Ryzen CPU with fragile pins. Intel CPUs have a flat surface, so there are no pins to clean.

Step 4: Remove Any Remaining Liquid

After using a few Q-tips, the CPU may have some excess liquid. We use a fresh Q-tip to wipe away any remaining liquid, not leaving any residue or fibres behind.

Step 5: Check for Functionality

Once thoroughly cleaning the CPU, you should apply a new thermal paste and reattach the cooling solution. Power on your PC and check to see if it boots up properly.

If it does, congratulations, you’ve successfully cleaned your CPU! If not, try re-cleaning the CPU to ensure no paste residue is causing issues.

In summary, using thermal paste cleaners is an easy and effective way to maintain your CPU’s performance and prolong its lifespan.

Following these simple steps, you can remove the old, dried-out paste and prepare your CPU for a new application.

Remember to use caution when handling the CPU and to choose high-quality cleaners to ensure the best results. You can keep your CPU running smoothly for years with care and attention.

Why Use Thermal Paste on CPU?

Using thermal paste on your CPU is like sunscreen on a sunny day. It’s essential. Without it, air gaps would be between your CPU and heatsink, which would reduce cooling efficiency and cause your CPU to overheat and fail. Plus, your computer would be like a person sweating profusely in a sauna. Not a pretty sight.

Factors to Consider When Buying Thermal Paste

Not all thermal pastes are created equal. Here are some factors to consider when buying thermal paste:

Thermal conductivity

Thermal conductivity measures how well heat is transferred from one material to another. The higher the thermal conductivity, the better the heat transfer. Your heatsink will be able to cool your CPU chip and emit excessive heat.


Viscosity determines how easily the paste will spread and how long it will last. A higher viscosity means the paste will be thicker and more difficult to spread, but it will last longer than a lower-viscosity paste.


The longevity of a thermal paste depends on many factors, such as temperature, humidity, and airflow in your system. Generally, a high-quality thermal paste should last at least two years in normal conditions. Choosing a product with good longevity is essential to use it sparingly.

Ease of Application

The ease of application of a thermal paste is also an essential factor when selecting one for your system. Some pastes are more accessible to apply than others, so read reviews or ask questions before purchasing. You want to ensure you can easily apply the thermal paste without issues or messes. Additionally, some pastes come with applicators which can make the application much easier and less messy than using your finger or other tools.

Types of Thermal Paste

The type of thermal paste you choose is important. There are two main types: organic and inorganic. Organic thermal pastes are made from synthetic materials like silicone and have good heat transfer properties but can degrade over time. Inorganic thermal pastes are made from metal oxides and other compounds, which provide better heat transfer but can be more expensive and difficult to apply.


The best thermal pastes will provide excellent heat transfer, allowing your components to stay cooler and last longer. Look for products tested and rated by independent sources such as Tom’s Hardware or XDA Developers for an unbiased opinion on performance.


High-end products may offer better performance but are more expensive than budget options. Consider the cost of the product relative to its performance before making a purchase decision.

How to Apply Thermal Paste Correctly

There are several methods for applying thermal paste, but one of the most common methods is often called the “line method.” This is exactly as it sounds.

Apply a thin line of thermal paste directly onto the center of the IHS (Integrated Heat Spreader). Avoid manually spreading the paste, which can cause air bubbles and uneven coverage. Ensure you use just enough thermal paste to cover all areas without leaving any excess on top.

For AMD Ryzen 7000 processors, Noctua has shared guidelines for applying its latest NT-H2 thermal paste.

According to Noctua, you should only apply a very small amount of thermal paste, about half the size of a grain of rice, in order to achieve optimal performance. Spread it like the photo below before you re-attach the heatsink.

It’s important to note that different types of processors may require different amounts and techniques when applying thermal paste.

For example, Intel processors may require more thermal paste than AMD processors. Be sure to check with your manufacturer’s instructions or consult an expert if you need clarification on how much or what type of thermal paste should be used for your specific processor model.

Cleaning Up After Applying Thermal Paste

Once you’ve applied the thermal paste correctly, it’s important to clean up any excess material from around the processor and heatsink area using a microfiber cloth dampened with 99% Isopropyl Alcohol Solution. This will help ensure that there are no air bubbles or other contaminants on your processor or heatsink which could impede performance or cause damage over time.


Thermal paste is a crucial component of your computer’s cooling system. It helps improve heat transfer from your CPU to the heatsink and keeps your computer running smoothly.

However, it’s essential to be careful when applying thermal paste and remove any excess paste from the CPU pins. With the above steps on how to remove thermal paste on CPU pins, you will have the chance to solve your CPU performance and other slow components.
