What is the thermal conductivity for my DeepCool thermal paste?

The thermal conductivity can vary between the variants of DeepCool thermal pastes(i.e. G40 would be rated at 5.2 W/(m·K), while the AD66(Z9) would be 4.5 W/(m·K)), so you might need to check the product page for each thermal paste to find out the exact specifications for your particular variant.
