Top 7 Best CPU Thermal Paste to Buy Online

CPU thermal paste is necessary to protect heat from the central processing unit. CPU paste is a needed item when connecting the CPU and CPU heat sink, and which is the most sensitive of all the personal computer parts. However, there are many different types, such as silicon paste, silver grease, and diamond paste. Also, the performance and price may vary, so it might you wondering which one to choose.

At this time, we will pick up the necessary points for choosing CPU thermal paste and the popular products purchased online. All the popular items are collected based on the product review and practices by the other user. Please select the CPU thermal paste that suitable for your computer and improve the cooling performance.

How to choose a CPU thermal paste – Buying Guide

From right here, let us discussed the importance and the tips on how to choose a CPU thermal paste, let’s consider this point and take down notes. Let’s see how to choose.

Choose the specification that matches your computer

The main point for CPU thermal paste is to select the products that match the specification of the computer that you are using. There are three main types, so let us understand the characteristics of each and narrow down the products that will match your personal computer.

Choose silicon paste for a standard performance

If you are using a higher specification like Core i5 processor or a lower computer, Silicon thermal paste is advisable because of its low cost. There are high conductivity and low conductivity products in silicon thermal paste, so it is a good idea to compare them.

For example, if you do not use a high-load 3D game or video processing, but you use it for writing and surfing, the CPU does not take much load, then silicon thermal paste can handle it in any way. Also, if there is a possibility of upgrading the specs or customizing, it is possible to change the thermal paste in a higher model.

Choose silver thermal paste for middle specs

If you are going to play a light 3D game on a computer with a specification Core i5 CPU or surfing over the internet, please consider silver thermal paste. Although the thermal conductivity of silicon increased, silver thermal paste maintains a more stable cooling performance.

Hence, a middle specification personal computer can start multiple tools, but if the cooling performance is low, it will cause freezing, so be sure to have it.

Choose diamond or silver for high-end computers

If you have a high specification performance CPU, such as the second generation of Core i7 or higher, and want to do with high-load work. You should select from products that are silver thermal or higher. Silver thermal paste is a product that cools well, but if the product mixed with a diamond substance, the CPU can further be cooled.

If the CPU goes into a thermal runaway, your high specification personal computer may freeze or even on startup becomes worst. To prevent this, you must choose the product that suits with higher specification and performance thermal paste.

Check CPU thermal paste conductivity

After establishing the thermal paste type and ease of application, let us compare the thermal conductivity. Thermal conductivity displayed in units, such as 9.0w/m K, which is a number that represents the amount of heat that travels per second. The greater the number, the higher the thermal conductivity, and the better it cools.

Some CPUs come with original thermal paste, but this thermal paste does not have enough thermal conductivity. Once it adheres, it is difficult to remove, so apply the thermal paste separately as possible to increase the thermal conductivity.

Choose with Insulator to prevent short circuit

Insulating thermal paste is also advisable for those who are not comfortable with unfamiliar thermal paste. In this case of conductive thermal paste, if the liquid leaks or blows out, it may cause the PC to short-circuit. However, insulating thermal paste, you can rest assured that if you spill it on the motherboard, and you don’t have to worry about short-circuiting.

Moreover, insulation is not important above all, so let’s decide whether insulation is necessary after giving priority to the balance between thermal conductivity and the thermal paste type.
