Thermal paste for G73JH GPU

Well, this week i will repaste my G73jh GPU

I always used mx2 in my desktop PC, but a few months use mx-3 and works well.

I've never tried ic diamond 7 but...:

IC diamond7: thermal conductivity : 4.5 W/m-K

AC MX-3: thermal conductivity: 8.2W/mK

Then Mx-3 should be betterthan IC d7... Has anyone tried MX-3 in G73 GPU?

 

MX-3 will be easier to apply, the ICD is like bubblegum coming out of the tube. I tried both, almost the same temps, although ICD has dropped my tss1 temps 1* lower than my tss0 temps at idle. With MX-3 my 3 temps read the same at idle. I got between 58-60 at idle. I'll report back if the temps drop any more. Right now they are about the same as mx-3

 

Hmmm...now I'm second guessing my need for a repaste. I'm also in a 28*C room and my temps are 55/60/57 at idle (while running 2 displays, the 1920X1080 lappy and an additional 1600X1200 LCD....if I just run the single lappy display my idle temps drop down to 53/58/54 and I haven't checked it loaded in a game yet) after being on for about 5 hours, during gaming and furmark I hit 83/88/81 and this is on stock paste...maybe I got lucky?

 

You got lucky! Congrats! Monitor your temps for a while. Asus stock thermalpaste degrades very fast.

 

Depends how you measure as they do not specify there is no basis of comparison - One man's 3.8 W/m-k Is another's 8 W/m-k

 

Just to note - High viscosity is OEM spec for bulk loadings above 90%+ for high reliability. It's considered a + in professional circles when selecting a compound

 

Good to see TIM(most popular around) manufacturer in this thread. Welcome!Hope you can help users around here.
BTW. I PMed you one question.Thanks.

 

This is so weird. A few days ago I tried Furmark, for the first time actually, and the temp hovered at 88c.

Yesterday I bought a chill mat that blows air up the bottom of the laptop, for watching movies in bed with the laptop on my lap and wanting to keep the option of fathering a second child open by not frying my family gem stones.

After plugging in the mat and running furmark again, my temp just keeps rising and in a few seconds the laptop shuts down. Tried it without the mat, same deal. Tried it the next day, same deal.

Why was it going so well a few days before? Will the new vBios fix this or do I have to mangle my keyboard?

I already ordered some IC7 expecting the response.

edit: I am not blaming the mat, i just mentioned it to explain why I reran furmark, and to my horror discovered that I now have a problem I didn't have a few days ago.

 

according to the instructions it says you need to use a litte more icd than you would other pastes. I used about 1/4 more than I did MX-3 is that about right?

 

Yeah...I had that happen to me...Furmark would ran fine for the first little while...then one day my temps spiked. Checked the paste, horribly done. I used AS5 for my fix and haven't had problems. ICD7 works just as good if not better based on the comments here.

 

Sweet, thanks I have Everest running all the time in the sidebar of W7 so my eye is always on all of my stats haha, I also use the OSD that shows GPU usage, temps, and FPS so even when gaming I have an eye to make sure I'm where I should be

 

Ok, I've had the machine for about 4-5 months now, and the GPU paste has DEGRADED! It is now very unstable, before I would max out at 105C furmark, now it shuts down. After several hours of SC2 it shuts down.

The only paste I found in my country is AC5 so I ordered it. Now on to my question, how would you apply the AC5? And where do you apply it? Both the heatsink and GPU core or just the GPU core?

I still have time since it has to be delivered from a different city, might as well get as much advice I can before repasting.

Funny thing is, it just started shutting down just yesterday, I would like to say ASUS pasting jobs are 'FAIL'. A video of repasting would be awesome, like how it would look before and after and application. I read in these thread that wrapping in plastic then spreading seems good with AC5.

I would appreciate all advices.

 

Sad to hear that you are having shutdowns. Anyway, I repasted mine with AS5. Method I used was wrapping plastic bag around your finger and spread thermal paste on gpu evenly.
Now here are the steps you need to do:
1) Disassemble laptop following BTOTech disassembly video.
2) Unscrew you GPU heatsink.
3) Clean old thermal paste from both heatsink and GPU using solvent(I used 90% alcohol bought in nearest pharmacy, others used isopropyl alcohol). And finish cleaning with lint free material.(I used special chemically clean tissues)
4) place drop of paste on GPU and evenly spread it over GPU
5) Mount your heatsink back and assemble your laptop
6) Turn your laptop and monitor temps.
As for video you can google how to apply AS5 on your CPU/GPU. There are a lot of them on youtube(describing application method). I can't post you links, because of youtube is blocked at my office.
You can go through this thread to find a lot of photos made by users. They should help you.
Good luck with your repasting. Waiting your update with new nice temps.

 

I think the ICD7 works so well because it's like bubble gum.

With the thermal pads on the memory and the poor springs on the heatsink you are not going to get the heatsink fully flat on the core. So the small gap near the memory will be nicely filled with this bubble gum paste.

 

beware with AS5, is electrically conductive

 

Oh, come on! All this horror stories about AS5! Have you ever heard, that someone fired his CPU/GPU using AS5?

 

CPU/GPU not.. but I know more than one that kill his motherboard/socket with AS5 and Coollaboratory Liquid Pro

AC mx-2 and mx-3 (or ICD 7, ICD 24) have better performance and aren´t electrically conductive... does not make sense to use AS5 (lower perf. and conductive...)

 

The only paste that is avalable for him is AS5. I can't say that AS5 is worst comparing to mx-2 and mx-3 (or ICD 7, ICD 24). Because for me it's not the thermal paste that makes difference, it's how it was applied. All pastes you mentioned perform withing 1C difference, if properly applied. I am not AS fanboy. But all these stories about conductivity and danger of using it are little farfetched. Hundreds of people still uses AS5 as their TIM and have no problems. As for G73 GPU, if you opened it you should notice film surrounding GPU. So, I think there is tiny chance of frying videocard in this case.

 

and they aren´t electrically conductive. all advantages

 

+1, thanks for the great advice, I have another question, after applying AS5, do I have to wait for a while before putting it back together or go straight after application?

 

I assembled it right afrer applying AS5.

 

apply heatsink after applying paste. AS5 has a 200 hour cure time.

 

Proud to say that I just did a re paste last night using IC Diamond 24 Carat.

Idle Before: 68c

Idle After: 55cc

Max Temp on Furmark: 108c

Max Temp on Furmark After: 88c

Room temp is about 21-22c and I didnt use anything to raise the back end.

Proud to be on team IC Diamond!

 

thnx again now all I have to do is wait for the delivery to arrive

 

Good luck!Hope to see your great temps after repasting.

 

Really nervous since this is quite an expensive machine for me. Anyways I read in your instructions that you didn't apply AS5 on the heatsink so there won't be a need to right?

Last and final question, I watched a lot of youtube videos on how to apply the TIM, did you use only a small bit like they did? Spreading the stuff evenly in a paper-thin manner?

Really appreciate this, my thanks.

 

Do not worry Just be focused and do it slowly. All will be fine. You do not need to apply AS5 on heatsink. Yes, I applied small bit and evenly spread it over the GPU. Hope that will help.

 

Awesome, can't wait for my AS5 now so I can start! Its really hot here in my country, ambient temp is like 25-40C depending on the weather, most of the time its around 35C.

I can't play my BFBC2 online anymore, after playing for like 30 mins the machine shuts down for safety due to the GPU temps. The only way I can play my games is by staying inside my room and turning the AC on full blast so the ambient temp would be around 18-22C. :cry: Electricity is expensive here!

Anyways thanks for your help Tim4! Makes me want to repaste the CPU too, and see how much heat reduction I'll get lol.

Edit: OMG, I just tried playing Prototype on max settings and after 30 mins I get 100C on GPU and 85C on CPU, LOL I think they both need repaste.

 

I get those same temperatures on Arctic MX2 for the same environment temperatures. Arctic MX3 will probably do the same thing.

There isn't much difference in these brand pastes. The only difference why some people get even lower temperatures:
- different VRAM and different grade of GPU;
- better working heatpipe and heatsink( there seems to be a lot of difference)
- not everyone is testing idle @ stock BIOS @ 700/1000.
- difference between BIOS 209 and 211( fan max threshold from 83C to 76C)

I still use BIOS 209 and at 88-89C my TSS0 is at 83 which is the threshold for the fan to kick in fully. So that is the reason why I won't get higher than 89C. If I would move to the 211 BIOS it would kick in at 76C which would mean TSS1 would be somewhat lower.

 

DONE! I have repasted! And it is awesome! Before re-pasting, my idle temps were 70-75C. After re-pasting with AC5 here are my idle temps (@700/1000 powerplay is off):



Also before repasting, my laptop would shutdown in about 5-10 mins into furmark, now it maxes out after 15 mins at 94C, that is just awesome!

Re-paste Experience:

So my AC5 arrived finally, went and loaded the BTOtech video, and started disassembling.

Keyboard was by far the hardest part, escape key is now a little bit elevated, but other than that, I reached the GPU with no problems.

After reaching the GPU and unscrewing the 4 screws, I had to pull it with a little force to get the heatsink off. Cleaned the old paste with isopropyl alcohol 70% solution and a lens cleaner cloth. I opened my AS5 and applied the paste. Put the thermal pads on the black memory modules and screwed the heatsink back.

After assembling my laptop back, turned it on and it was all good. Fired up GPU-Z only to find HORROR! 85C on IDLE! I was shocked and I panicked! What the hell happened??

I ran furmark and boom after 3 secs the temps shot to 127C and the laptop shutdown. I was scared to death! After researching a bit it seems that you have to push and take out some of the AS5 first before applying, and I wondered why the paste was so liquid like instead of pastey like.

I reopened my laptop and cleaned off the liquid like AS5, then applied it once more. Now it was pastey like and after applying it properly for a while, I was satisfied.

I assembled it back and there it was, lovely temps, my heart almost flew! I was so happy an satisfied. Overall I must have level'd up with this experience, LOL. Hope this helps to some of you future re-pasters!

 

At least you didn't break the speaker connections

 

Lol yeah, I was like extremely careful with those, and with the keyboard too, since I don't have the money to replace it. Took me a total of 4 hours on the first disassemble and 1 hour on the second.

At least nothing got damaged, really happy. What pushed me to re-paste was your temps after all. Thanks for the motivation. Really wish there was an ICD7 official retailer here in my country, but hey at least we got AS5, lolz.

 

Don't forget about 200 hours curing time. Your temps should decrease 1-5C according AS5 official datasheet. So, welcome to the club. Happy for you.

 

Thanks, in for like 15-20 hours now, will update when reached 40-50 hours. Cheers~

 

Need help

Before repaste my gpu temp was 108C.

After repast (using alot of AC5 thermal paste):


After repast (little thermal paste):


But now 2 days after:


I opened and reposition the thermal paste on memories but not work. I need to pass the new thermal paste on memories too?

 

FYI the curing time includes cooling off, off time also. Curing is heating up and cooling down. So don't leave your computer running some 3D graphics for 200 hours, that's not good. Just means, use your computer, expect improvements as you use it, don't need to do anything special.

Some I read just run a quick benchmark each time they use it. Whether it's prime for CPU or Vantage for GPU, should be not problem. That's all. Or just play a game

I like OCZ Freeze the best. Most consistent Top 2 or 3 of the TIM I've seen behind the LiquidPro. Yes I've seen more benchmarks showing Freeze is better than ICD7. And it's by far the easiest TIM I've ever used to apply and it has no curing time.

 

AC mx-3 (and mx-2 haven´t curing time. I think that mx-3 should be better .

 

Use this method: How to Apply AC5. Thats how I did mine.

 

didnt work

Need Help

 

I've heard of some Radeon chips not taking well to AS5. This seems to be the case here. I'd keep trying just to be sure, but if you run out of paste, buy a different one.

 

Very Strange, thats how Tim4 and I repasted with AS5, did you put the Thermal pads in place and putting a small amount of pressure when you screwed back the heatsink?

 

That's an awful lot of AS5 applied.

 

@proteus_br
Everything depends on your heatsink too. I heard, that there were some G73s with loose heatsinks. Did you tighten all screws on your GPU heatsink well?

 

Want to apologise in advance if this has been answered before, but I want to confirm that the memory thermal pads DO NOT need to be replaced before re-attaching the heat sink (after re-pasting GPU), correct ?

 

correct

 

so according to asus support, dismanteling and repasting voids the warranty they tried to convince me to send it for RMA, but as i read many users endedup with the exact same issue before they sent it for RMA. i am clueless :/

 

EDIT: super low temps were with power pack unpluged at the wall :O
furmark still shown 700/1000 so i never noticed, all this excitment for nothing
got solid 10-15c less on full load then what i used to have so i'm still very happy

repasted today with MX-3 (had tube already here and knew it works good)
was bit worry about the keyboard bit but got it done so nice you can't tell it was ever touched.

didn't really have problems (yet) but i knew it would come because summer is yet to come down under.

was idling around 67C and furmark would hit 109C after 5min
room temp 26c

after repasting i got to say asus cooling system is fantastic but such a shame they ruined it by using rubbish thermal paste/pad

i'm idling now at 60c and furmark after 5min hit .....drum roll.......... 92c


room temperature today is around 26c
since i was already inside i also done my cpu and i lost good 5c there as well

i'm ready for summer heat now

anyone that knows how to use screwdriver should get it done, there is nothing too complex and outcome is just fantastic.

thanks to BTO for video guide

 

Then i will use mx-3

 

How about posting a pic with furmark running and hwinfo sensor display CrocAUS. Let it run out for at least 20 min or more.

 

The airflow reading for your hard drive will tell you pretty much how cool the air is entering your laptop. This will give you a good idea on how your temps will be relative to others who post this information. If this temp reading is high then don't expect your idle and load temps to be low like some of the other ppl who post low temps in idle and load.

If you post your temps please include a screen shot of your hwinfo sensor screen so that others don't think they applied their paste wrong because they are using the same type and are not getting temps that you are.
