Size
Knowing the dimensions of the thermal pad, you can evaluate how it will suit certain tasks. A thermal interface is cut out the size of a chip or with a small margin.
Items in set
The total number of thermal pads in the set.
Sets of several pieces are cheaper in terms of one thermal interface, but the need for them arises infrequently. For isolated cases of replacement of thermal pads, one copy in a set will be quite enough.
Area
The area of contact between the thermal pad and the chip surface, measured in square centimeters (cm²).
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
