Thermal Paste has been an important part of electronic components for the last 4 decades. Still, the question about its best application method is mysterious. Different people adopt different techniques to apply the paste. But which works well or what is the best method of thermal paste application?
In this article, we will discuss different application methods of thermal paste. Their pros & cons will assist users in choosing a reliable method. We will also discuss the impact of each on temperature level. Finally, what must be avoided during the application of thermal paste? Let’s dive into the discussion now,
Basics of Thermal Paste
Thermal Paste maintains the temperature level of various electronic devices. It is a substance applied to transfer heat from the components to the heat sink. It also fills the gap between the two surfaces and ensures a smooth attachment.
Thermal grease is composed using a mixture of base material and fillers. It includes silicone, urethane, carbon, aluminium oxides, boron nitride, and zinc oxide. Other ingredients are also added as per the requirement of its type.
One can use thermal grease in the CPU, GPU, and other similar components. Thermal grease works efficiently for a longer period and is easily available TIM. It is the choice of high-end users for a consistent and stable performance.
– Core Features:
- Thermal Paste features a thermal conductivity of about 5-20 W/mK.
- Thermal Paste offers an operating temperature range of -50 to +150 degrees Celcius.
- Thermal Paste is easy to apply/remove.
- Thermal Paste is easy to find and afford.
- Thermal Paste is reliable/durable/stable.
Thermal Paste Application Methods
1 – Pea-Size Method
The pea-sized method is the most followed method of applying a thermal paste. Here, a pea-sized quantity of paste is placed on the component. Once the heatsink is installed, the paste automatically spreads on the surface. This order of spreading minimizes the risk of creating air bubbles. There is no need for a specific type of paste spreader.
- Easy for Beginners
- Fewer Chances of Air Bubbles
- Efficient Spreading
2 – Dot Method (5 dots)
Well, the pea-sized and dot method is almost the same. The only difference in the dot method is the addition of multiple dots. It is also called the 5 dots method, where the thermal paste is used on 5 different spots on the component. Similarly, the paste spreads on the surface after installation of the heatsink.
- Suitable for Large-Size Components
- Covers more Surface Area
3 – Cross Method
The Cross Method is also known as the X Method. In this technique, the thermal paste is applied to a component in a cross or X shape. It covers the component’s corners from one end to another meeting in the center. The main focus of this method is also to get smooth coverage and avoid air bubbles.
- End-to-End Coverage
- Anti-Air Bubbles Technique
4 – One Line Method
In this method of thermal paste application, a straight line is drawn using thermal paste on the component’s surface. The main point of focus here is to draw the line in the centre and keep the order of spreading outward. This method also helps to spread the paste smoothly and avoid air bubbles.
- Suitable for Intel’s CPUs
- Provides Smooth Spreading
5 – Three Line Method
The three-line method is also similar to the one-line method but with a difference in number of lines. Here, three thin lines are drawn on the component using thermal paste. It is up to the user to draw the lines horizontally or vertically. Make sure to keep the lines as thin as possible to avoid over-dose of thermal paste.
- Better Surface Coverage
- Better for Large Components
6 – Spread Method
One also needs a paste spreader here to spread the paste on the component surface. That’s why the method is known as the spread method. The spread method simply includes applying a required amount of paste on a component. Then spread it across the whole surface, install back the heatsink and you are ready to go.
- Easy for Beginners
- Zero Chances of Spreading Issues
Which Technique Works Best?
Although the pea-sized method is the commonly used technique in thermal paste application. But our observation in this regard is different. Choosing the right amount of paste to apply is more important than a specific method.
In thermal paste application, the right amount always leads to a stable performance. Even though, these methods will remain the methods forever. But still one must keep an eye on the quantity & quality of the thermal paste.
Another important factor here is the proper spreading of paste on the surface. It overcomes the creation of air bubbles and ensures the smooth transfer of heat. So, whether it’s the Pea Method, Dot Method, Line Method, Cross Method, or Spread Method…
No major changes are noted in the temperature, until or unless you apply the required amount. Keep the rumors aside and always prefer the recommended amount. It is beneficial for the stable performance and lifespan of electronic components.
Dos and Don’ts for Proper Application
– Do’s
- Clean the surface of the component + heatsink before applying thermal paste.
- Keep the required accessories with you e.g. cloth, cleaning liquid, and spreader.
- Always check the compatibility of thermal paste with your components.
- Always maintain appropriate pressure between the component and the heatsink.
- Always choose a reputable and quality manufacturer for your thermal paste.
– Don’ts
- Don’t apply a thermal paste without cleaning the surface.
- Don’t apply a thermal paste more than the recommended quantity.
- Don’t apply a thermal paste that is expired or old.
- Don’t apply a thermal paste manufactured by a non-reputable brand.
- Don’t apply a thermal paste if you don’t have the related expertise.
