Asus G73JH / I am considering replacing thermal pads and paste

Hello everyone and I must say I found some pretty useful information about my laptop, a lot more then I expected.

Anyways, I system temps which are anywhere from 93"C to 100"C (typically hovers at 95ish), and from what I can tell the thermal paste tends to deteriorate over time. I am already seeing high temps and can only assume they will get higher from what I have read.

I found this video
YouTube - Asus G73Jh Disassembly Take Apart G73 Replace Video Card G73 service manual
that guides you to disassembling your laptop. This video will definitely save a lot of time thanks to this forum.

I have 3 questions.
1
If I applied thermal paste and thermal pads myself, will that void the warranty? My guess is no as long as you don't leave behind signs of any alterations and well you don't say anything lol, but I like to be sure. This is an expensive laptop lol
2
I use Arctic Silver 5 on all my machines, is there a better paste then this or does it still hold the crown? I like to apply the best thermal paste possible and as far as I know, AS5 is still the top of the line. Whatever I decide use, it will be applied on both the GPU and CPU.

I would like to replace all thermal pads (just for good measure), what do you guys recommend? I read a forum which suggested Coollaboratory Liquid MetalPad, are these consider the best solution for this laptop? Obviously these will go on the memory chips of the video card and maybe even the chipset.

 

1. As long as you don't break anything, they will have no proof that you've been inside.
2. ICD7 seems to be the best stuff, but just about any paste you use will get you within a few degrees of one another (so don't obsess over it).
3. If you're replacing the pads, I'd do something cheap, like a copper mod since you only need a little bit of it.

 

These forums should be cleaned out or somethin, cause this is the 4th time a topic has been made for those exact same questions .

1&2: Opening up the CPU WILL void the warranty, since there's a sticker on it that says ''warranty void''. The GPU doesn't have one.
Although, when techs will open ur laptop, they'll see that there has been made some changes ...
And ye, AS5 is good enough, the best will only take 1-3C off under load.

3: Make sure that when you buy pads, you buy the correct ones! Cause there's a gap between the vram and the sink. But in my oppinion, the replacement of the pads on the vram aint really necessary, since the temperature sensors are all on the GPU itself. So there's no way of knowing if they actually do any good or not. But than again, thats my oppinion .

4: Good luck ^^

 

NOTYOU, what do you mean a copper mod? You referring to creating copper shims?
SHoCKIE, I did not know there was a sticker, interesting. So there is no way to ad AS5 without voiding the warranty on to the cpu then right?
You think adding AS5 is enough to void the warranty?
So you really think its pointless to add better thermal pad on the vram?

 

Yes, copper shims between the vRAM and HS (and GPU if it needs, but probably not).
There is a warranty voiding "sticker" on the CPU HS covering one of the screws. You may be able to remove it by heating it up so the glue softens or wetting it so the glue is removed, but when you re-assemble you'd have to put some glue back on it.

As for AS5 directly voiding the warranty, no. Removing the sticker (technically yes, but how would they know?) or damaging the internals (yes).

It may be worth doing a copper mod on the vRAM (I plan on doing so once I can afford to have my machine go down for a while) since it's the hottest running part of the computer.

For example, I did a stress test just an hour ago with OCCT (CPU) and Furmark (GPU) at the same time for ultimate burning and my CPU only topped out at 73C and GPU at 84C (core) / 94C (vRAM). So, these temperatures are definitely fine for a worst case, but it would be nice to have them lower (only for the GPU, the CPU is nowhere near the range where I'd be worried).

 

This would require buying a sheet of cooper and cutting them up, and on top of that I would need to make sure the copper shims are completely FLAT.
I've done this before for the HP DV6000 and DV9000 series for the northbridge chipset. In theory its suppose to drop the temps by 10''C
At the moment, I think all I can really do is just apply AS5 to the GPU. The copper shim idea seems good but I need to know how think the shim needs to be, will 1 be ok or would it need 2 sheets of copper shims.

If I do add something to the vram, I think I will just be applying the Coollaboratory Liquid MetalPad. But shockie is right, I need to know how thick they are suppose to be. Any ideas or is just adding AS5 to the GPU is enough?

I thought about buying a Laptop cooler, the one made by Antec, which is this one
Newegg.com - Antec Cooling system for notebook computers Model Notebook Cooler 200

 

I'm currently running at 51C for my GPU temp (MemIO), with my cooler on maximum. (its the Zalman NC-2000). When I turn it off, it goes upto 56 in about 2 minutes. So it does pretty well. I don't know about the one you showed, but read some reviews about it, go look it up on youtube etc..

Adding AS5 (or in my case OCZ Freeze) was good enough for me, since hte sensors are all on the core itself. the pads on the Memery are good enough, and replacing them is a hell of a job, since you gotta know the exact thickness between the copper plate and the memory itself...

 

Hey sorry to hijack this thread but can you comment on what your max temps are without the cooler, on the cooler without it being on and at max speeds? Thanks

Also I'm wondering if I should repaste. With the back raised, it idles at 58c at stock clocks. With furmark it goes up to 98c. I'm still using stock bios and vbios

 

Yea-i please too
In my G73JH i have-52*C zalman max 56*C zalman off - idle
and 97*C zalman max 103*C zalman off after 5 minutes in furmark - its ok ?
I dont know why but i must turn zalman about 180* - rear of the notebook must be most down than front (hot air will go faster if is how i say)
And- its ok ? 105*C MemIO and 84*C shaders and DispIO ? shaders and dispIO in furmark i think are ok - but memory on gpu is too hot

 

In comparison, here's a 5 minute Furmark:

As you can see, 73.5C on core, 76.0C on MemIO, no added cooler. So no, 103C is not OK. Your laptop is due for a repaste on the GPU.
