Weight
Product net weight (without packaging). Knowing the amount of thermal paste in the packaging, you can estimate how much it will last.
Viscosity
Thickness of thermal paste. The viscosity of the paste is considered to be optimal in the range of 160–450 poise. By eye, the consistency should be slightly thicker than that of hand cream or toothpaste. Too liquid thermal paste during operation can leak out under its own weight, too thick — it will not be able to fill the microcracks on the surface of the processor and heatsink as much as possible.
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
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.
