View Full Version : Replacing thermal compound in G551JW

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:
49802
- 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.

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.

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...

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.

49811

49812

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

After assembly we can see results:

Now my G551JW is no throttling at all during FurMark 1080p test (reaches 74C at the end of the test, and not after 13 seconds, like before changing thermal compound).
Also 3DMark FireStrike changed from 4450-4510 to 4700-4716 (always over 4700). Of course in both cases (before and after) it throttles at 74C but with better cooling throttling is not so dramatic.
I see that GTX960M will be capable to reach 5000 score in 3DMark easily if not throttling at all (I wish I had such vbios...)
But now 27% progress in FurMark, about 5% progress in real speed thx to better cooling.

Total gains I have now (overclocking + better cooling):
* 3Dmark was 4040 factory, now 4710 at average. +16,5% speed. It is now similar to GTX 965M performance.
* FurMark (very optimistic now, as no throttling at all during test): from 2120 to 2800 = insane +32%

Now I look to buy best cooling pad for notebook, maybe this will sink temperatures a bit (never used that gadget, I have no idea if this helps or not). But my G551 is now running Witcher 3 with high graphics setting and middle setting for HairWorks (before - hairworks was not possible) and full HD and almost never drops under 30FPS.

Wow impressive. I don't understand why they don't use this thermal compound for assembling to begin with. What is the extra cost for a few drops?

Anyway, I don't think a cooler would be very beneficial, considering the small size of the intake, located under the touchpad...

Piro

Total cost of such operation per notebook is surely lower than 1$.
I have paid 10$ for Coollabolatory Liquid Ultra and I see such 1ml in syringe is enough for 10 notebooks for both CPU & GPU.
I have spent 1 hour of my time for disassembling, applying & assembling my Asus back - but for sure during a production phase such notebook is opened and there is only a question what thermal compound will be used.
If they are afraid of elec-conducting compound, there are for sure good dielectric compounds, like Arctic Silver 5 or Prolimatech PK-3.

About cooler pad - all in all I will buy one and compare (and post results). I love testing :)

which ram is installed? :D with 2133 Mhz? just interesting i want to know, coz they boost automatically to 2.600 Mhz, without any bios settings..boost that speed how the bios it allowed... sry for ma **** english :p

To be honest - haven't checked that. I will let U know.

Wow, this is amazing. I will be attempting this after I buy the tools. Can you provide more tips for disassemble and reassembly? I want to make sure I don't screw anything up. This is fantastic work Piro, I like seeing people think outside the box and make a good product even better.

You should have made a video it would have been better will for me anyways, and also put it on YouTube, you'll get a lot of hits, mine is get hot too

I just did this as well, although I should have taken a video.

It was amazing.

if not a video, maybe a detailed tutortial?

If the original poster wouldn't mind, I could write a tutorial using the original images he provided (preferably the originals, as the ones uploaded to this forum are incredibly low resolution)

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.

All - ok, I will publish all photos at my server and I will provide links, so hires photos will be available.

Piro, how did you manage to mod vbios?

Another question, If I repaste my gpu + cpu, I'm thinking about using Gelid Extreme. Collaboratory Ultra seems to stick the die to the cooling if it's there for a long time. What do you guys think about the best paste to use in our system, the Gelid, the collaboratory or Arctic Silver 5?

wow this is really such an amazing insane methods you discovered , But what about GPU temperature , Is there any way to increase it ?

Any chance you can make a video for a step-by-step breakdown of how you opened the computer?

yesterday i replaced thermal compound , i got -12 degrees with clocks 1423 core clock , and 2649 memory clock, playing ultrasetings Star craft 2 , Dota, and BF 4

Anyone one have a step-by-step guide to opening this laptop up?
Where do I start to pry open the sides? How do I avoid breaking the latches? After I get the sides off, what do I do?

How did you unlock the voltage?

hi!!

I have a G55VW, is it possible use the same guide to change the thermal compound?

I did it replaced with arctic mx
also I undervolted the cpu -50mv
now my highest temperature underload is 73 or 74 (it reached 84 before the process)
I am so happy wit the results no throttling

My G750JZ has started switching off because the CPU hits 80 degrees C, I've already cleaned and checked the fan so I think this will have to be the next step. Thank you for posting this!
