Erazer BEAST X20 MD63925 - liquid metal thermal paste?

[TheXerxis]

Hello everyone!

I have a question for you. What materials are used in this laptop Beast X20 MD63925 on heatsink?

I trying to figure out that can I apply liquid metal for cooling CPU? On GPU i will put normal thermal paste cuz gpu do not have high temps.

But CPU - i tryed a few thermal paste's but i can't get satisfying results. 

CPU section is a little bit different - i mean heat sink that touching CPU ihs looks like made of "aluminium?" On GPU is cooper.

But CPU is surrounded by sponge - that makes me think is protection to  prevent sail away liquid metal to PCB(motherboard)

So. The question is - can i put liquid metal on cpu side cooling?
