Ok, guys I took one for the team lol. Don't even try to pull the adhesive cover off the cpu block it will tear mine did.
The paste is dried and cheap, it just flaked right off.

After I cleaned it good with alcohol:

Liquid metal applied (Be careful you want a thin layer due to the pcb being so small and it took awhile of massaging to get the liquid metal to stick):

Here is where the back screws are so you don't have to peal the adhesive cover:

Idle temps I am seeing a 3C drop and I put the server under a load before and hit 65C and after with same test I hit 45C.
So end result 20C improvement.
Even if you don't do liquid metal I recommend new thermal paste.
