Type
- Thermal paste. Thermal interface applied to the "hot" elements of the computer motherboard to provide the necessary thermal conductivity. The compositions of thermal paste contain various types of heat-conducting components in the form of nanodispersed powders and mixtures. Liquids with a low level of volatility of synthetic or mineral origin are used as a thickener for thermal paste.
-
Liquid metal. Liquid metal consists of alloys with a high level of fluidity (zinc, gallium, tin, etc.). Its competitive advantage is a much higher thermal conductivity rating (7-9 times higher than that of conventional thermal paste). Also, liquid metals retain their properties in the widest temperature range from -273 °C to +1200 °C. The reverse side of the coin when using liquid metals is the complexity of applying and removing, the impossibility of using with aluminium radiators, the electrical conductivity of the material (any contact of the thermal interface with open contacts can cause a short circuit).
Package
— a href="/list/247/pr-47871/">Syringe. The most convenient packaging for thermal paste. Due to the fact that air does not penetrate into the closed syringe, the paste is stored in it for a long time. From a syringe, it is easy to apply and accurately dose thermal grease.
—
Tube. A soft tube for pasta, from which the contents are extracted by squeezing. For spot application, tubes are less suitable than syringes, but as a packaging for long-term storage of thermal paste, they are excellent.
—
Jar. A container in the form of a small jar in which it is convenient to store the thermal interface. To apply the paste directly from the jar, you will need to have a spatula or applicator brush on hand.
Weight
Product net weight (without packaging). Knowing the amount of thermal paste in the packaging, you can estimate how much it will last.
Thermal conductivity
The fundamental indicator for pasta. The parameter determines the amount of heat passing through a unit of substance during a unit of time. The higher the thermal conductivity of thermal paste, the better. For home computer processors that do not get very hot, in principle, any thermal conductivity is suitable, but for high-performance gaming stations, it is advisable to give preference to compositions with high thermal conductivity (from 5 W / mK and more).
Operating temperature
A fork of operating temperatures at which thermal paste retains its properties. Usually, the upper ceiling of the operating temperature is up to +150 °C. There are substances with a wider temperature range of properties, but they are usually used for industrial purposes. The maximum temperature value often becomes important when overclocking the processor
Paste colour
The most widespread are substances of grey and blue colour, as well as their derivatives.
Scraper
An essential accessory for accurate and even application of paste from a tube or jar.
The spatula helps to select the correct dosage of thermal paste and properly distribute the substance on the surface of the processor. However, it is not found in all kits, there are
thermal pastes without a spatula - an option if the spatula is left from the previous kit.
