@HottestVapes thanks for your answer!
Yes i think thermal pads it's no diference and are pre cutted, so easy installation ?
About the thermal paste I found thath the phanteks thermal paste is only 4.5 W/mk.
The Grizzly Kryonaut is 12.5 W/mk, almost 3 times better thermal conductivity ? and the liquid metal is 73 W/mk ??
