Replacing thermal compound in G551JW

Piro
Level 7
I publish here my results with replacing thermal compound (or better to say - two compounds used in my G551JW) to better ones. I will use two compounds for some reason, explained later.

This my patient:
49791

Set up with modded vbios, GPU = 1400 Mhz, Mem = 1500 Mhz, -81mV
It throttles GPU at 74C, this makes me nervous, but I cannot change it at the moment.

Here is FurMark test before any mods (scoring 2202 points overclocked and 2120 factory):

First of all we will need some tools:

- precise screwdrivers
- sharp spatula (I've bought mine at Spatula City of course... 😉
- isopropyl alcohol spray
- tweezers
I use also earthing/grounding mat with wirstlet.

I have pointed all screws that have to be removed at this phase.
After that we need to remove SDD/HDD, DVD drive, battery & memory.

There is no screw missing btw, the "missing" screw for HDD cage is the same screw that holds the bezel. So the screw has two purposes, hold the plastic bezel, and the HDD cage 😉

Holy ****, U R right!
Thx and sorry Asus 😘

BTW I still think this is to confuse me. They have confused me at the level 2...

Then we need to use spatula and open step by step whole frame to get inside. While it's opened we need to unplug screen & touchpad to separate mainboard/keyboard part from screen/bottom frame part.

If you are interested in that I will publish tommorow rest of photos & instruction and results after using Coollabolatory Liquid Metal Pro as main thermal compound.

did anyone notice the other components have very little contact with the heat sink and a lot of thermal compound

The contact with the vRAM and whatnot wasn't perfect, no, but very well enough and still warranted a replacement of thermal paste.

So I apply Collaboratory Ultra (I thought I ordered Pro, but I ordered Ultra). It is really thin film of liquid metal. I used one small drop per each processor.

and then I use Arctic Silver 5 for all other elements, that were binded to cooling by silicone foam.
