How to choose thermal paste?

First you need to figure out what thermal paste is. This is a special substance that improves heat transfer between the heated part of the computer and the cooling element.

When choosing a tool, pay attention to its performance characteristics:

1. Thermal conductivity level. This criterion shows the ability of the paste to transfer thermal energy from heated elements to cooling ones. In budget funds, this figure is only 8 W / m * K, but experts recommend buying thermal paste with a thermal conductivity of 1.5-2 W / m * K.
2. Consistency. This indicator is also called viscosity. High-quality thermal paste should not be too thick or liquid. Unfortunately, this indicator is rarely indicated on official websites or packaging, so most consumers prefer to evaluate the viscosity of thermal paste by touch.
3. Packing volume. As a rule, thermal paste is produced in small tubes or jars of 4-8 grams.This amount is enough for several replacements. At the same time, it is important that the packaging is equipped with an airtight lid, because during long-term storage the product thickens and loses performance.
4. Compound. There are several types of thermal pastes on the market today. Silicone are considered simple and inexpensive, but their performance is enough for a home computer. Ceramic have a thermal conductivity of up to 5 W / m * K, but at the same time they are inexpensive. But the most effective are diamond thermal pastes and products based on semi-synthetic silver. They have high thermal conductivity, are easy to apply and do not spread.
