Pookie

Ok,since its REALLY easy to open pocophone and get to see its "liquid cooling system" i was wondering,is there any reason or performance benefit to put liquid metal inside the pocophone,instead of some thermal paste? From the screenshots you can see you have a pretty big area to play with and for me it seems "safe" to do. Is there any freak that has done this with his phone?
