What are the key points for buying thermal grease for desktop machines? What do I need to pay attention to when applying it?

Computers are an indispensable appliance in the daily office, and desktops are more suitable for use in corporate offices than laptops. Desktops have good heat dissipation properties and can transfer the heat generated in time, whether in summer or winter. The main reason why desktops have such good thermal performance is the use of desktop thermal grease.

What are the key points for buying desktop thermal grease?

1. When buying desktop thermal grease, you need to know the thermal conductivity, heat transfer coefficient, and thermal resistance coefficient of the grease. Different brands and different silicone greases have different characteristics of these three coefficients. If you buy one with too high a coefficient, it is easy to waste it, and one with too low a coefficient is ineffective.

2, when buying desktop thermal grease, people pay more attention to the service life, the general brand service life is about 3 years.

3, try not to buy the desktop thermal grease containing silver, although this type of thermal grease thermal performance is good. Once there is an overflow to easily conduct electricity, resulting in electrical burnout.

What do I need to pay attention to when applying thermal grease to my desktop?

1. The main purpose of applying thermal grease is to fill the gap between the electronic components and the heat sink. Try to ensure that the surface is as flat, even, and thin as possible during the application stage, as applying too much will affect the performance more than it is worth.

2. When applying the desktop thermal grease, observe whether the surface of the substrate is clean, and try to reduce impurities on the surface to better adhere to the surface of the substrate and bring out the thermal performance.

The use of desktop thermal grease can prevent the computer from shutting down due to high temperature and ensure the normal use of electrical appliances. As for filling material, thermal grease is used in very small quantities in machines every day, so users should not be greedy for cheap when buying it to avoid losing a lot for a small amount.
