thermo or thermal paste?
I have heard of thermal paste - you put it between your processor chip and the heatsink in a computer in order to increase the efficiency of the heat transfer

I have heard of thermal paste - you put it between your processor chip and the heatsink in a computer in order to increase the efficiency of the heat transfer

so if i put thermal paste on the surface it would make sure that the heat of the surface is not lost to the environment.

Also what is thermo paste?

one more question is thermal paste same as silicon greases, meaning do they have same function.
