G73jH overheating after thermal repasting

Hi,

I got my G73 around June, and it worked fine for about 2 months before it started overheating on WoW. The right end of the laptop would get really hot, and would just shut down after a while. REALLY hot. I called up the ASUS guys here in India, and they repasted the thermal paste and ever since then everything has been fine. Until the Crysis 2 demo. For some reason, whenever I run the new demo the middle end gets hot (definitely not as hot as earlier), and the laptop shuts down. The AMD GPU clock tool shows steady temperatures of 90-95 degrees. Is the CPU the problem? Because whenever I run Crysis 2 the fps is awesome on max settings, but sometimes quick turns to the side can get a bit laggy (heard somewhere that this signifies some CPU problems). Forgive me if I'm being completely idiotic here, but I really want to play Crysis 2! I've been playing Dragon Age 2 along with Crysis 2, and haven't encountered a problem with that as yet. Help would be appreciated.

Thanks

 

repaste again?

 

Your GPU temps are pretty hight. What are your CPU temps?
I recommend opening the system and cleaning it, dust may have clogged the vents or similar. Also repaste both GPU and CPU (unless the CPU temps are fine of course) I recommend repasting it yourself, it's not that hard as you may think and you probably have a better result in the end when doing it correctly. But if you feel uncomfortable doing so let the Asus guys do it.

 

almost g73 have overheat problem after 3 months or sooner, mine too bought april, overheat on june, RMA twice, tha'ts sucks!!!

 

Downloading Everest, will post the CPU temperatures soon. What is a good CPU temperature for the G73? Why does the fan on the right run all the time, but never the fan on the left? (This happens with everyone right). I'm going to run dragon age for 2-3 hours and see how it goes with that.

Also, is there some youtube video you know of which tells me how to repaste the thermal paste. I would look for it myself but don't really know a good way from bad :/

Thanks again.

 

The fan on the left is the CPU. The one on the right is your GPU. Sounds like you need a GPU repaste. I doubt your CPU needs it but you can do it if you want to. I'd wait until your warranty is over.

 

Okay idle CPU temperature is 48 degrees, and idle GPU temp is 70-75. When I ran dragon age 2 for about half an hour, AIDA showed CPU temperature as 62 degrees, and GPU as 91, 102, and 95. I need to repaste again?

 

Really high idle temps for the GPU, the CPU is perfectly fine. It's time for repasting. There's a slight possibility that it's because of dust and not because of the paste, but that's almost impossible as the CPU temps are fine.

 

What is the ambient room temp? And are you gaming on a hard surface so the area underneath the G73 is clear? The notebook automatically powers off when the GPU hits 110C or so as a thermal protection mechanism.

Paste does not make more than a few degrees difference unless they didn't put enough on to cover the entire GPU die which is unlikely. The problems with these notebooks are that the GPU heatsink is somewhat inadequate and the RAM thermal pads press up on the heatsink and reduce its contact area on the GPU itself. Basically the GPU cooling sucks which is ridiculous considering the size of these notebooks. There's plenty of room in there to design better cooling but they skimped.

Depending on your ambient room temp, 90-100C is a distinct possibility when gaming. Idle will probably vary from 45-55C. It really all depends on room temp.

 

If you hit 100, but no higher, you're probably fine.

 

New development! I noticed that when I was playing Crysis 2, and the temperature was 106 degrees, that fan speed was still 30%. Thats not normal is it?

 

Fan speed isn't read properly.

 

That makes more sense. So repaste it is... Only problem is that I've already gotten it done for the ASUS guys and although it did improve the problem, it didn't fix it. I'll see what happens.

Thanks for all your help man.

 

They may have messed up the repasting... Fastest and easiest way is still repasting it yourself.

 

Okay just got it back from the ASUS guys and idle GPU temperature is now 58 degrees! Success?

 

Sounds good to me. I've got a thread about it in my sig.

 

Sorry to post on your post I just didnt see the point in starting a new thread as my problem is very similiar to yours. I have ordered some AC5 today to repaste as I have noticed my temps gradually getting worse.


GPU: Idle 51oC Full Load 90oC Furmark full burn 5 mins 101oC
CPU: Idle 50oC average Load 60-70oC full burn 84oC

I have repasted many CPU's although not a GPU before but it looks quite straight forward however I couldn't see it mentioned in previous posts about the heat pads over vram modules do these need to be replaced or can they just be reused when the heatsink is reattached.

Any advice is appreciated.

 

They're reusable. It's the same process as doing a CPU, but the die size is smaller. You might benefit from just blowing out your vents, if your heat is rising slowly... since you've already repasted, it seems that you've probably just got something going on for your radiator fins.

 

Thats good to know I notice that the heatsink is so basic I really cant believe that laptops of this power are not given a bit of copper these days clearly cost over reliability is not an issue for Asus.

I havent repasted her before it was the previous owner that did or mention that he did which makes me want to do it myself properly even more especially as some people talk about a 10oC drop in some cases, I will entirely clean the air flow as well to make no dust is blocking the way.

Also yes the heat is only gradually rising it holds 90oC on full burn and then over several minutes reaches 101oC that is when I stop the benchmark.

Is the entire process quite straight forward? I understand that the entire casing needs to be unscrewed and im having a look at the post on dissasembly at the moment.

Is AS5 ok to use? I have a pot at home you see but I hear a lot about IC7

 

The heatsink is ... unwieldy. As5 is fine, but ICD is nice for coverage ... it's thick enough that if the heatsink isn't flush, it fills in the gaps.

You may not get a huge reduction in temps - I would really, REALLY try blowing out the fans first, and see if that makes a big difference.

 

I took your advice and went for shifting the forced air through the fans to get rid of the dust and now im only reaching 92oC at full burn on furmark for 5 mins down from 101oC :/

I will keep the thermal paste that i bought for another time me thinks

 

You can always repaste if you want to ... but you may not get *any* improvement. You might get a 5 degree drop ... or a 5 degree increase. The way the GPU is set up, the memIO is on an outside edge of the chip, but the core and shaders are in the middle. (see here ... from ... Wie ist Ihr Deutsch)

So, if your paste is done properly, but just not to the edges, you might have trouble getting good contact. Anyways, long story short? I'm happy with a max 91/97/92 for 1h on furmark, because while gaming, I never break 85. Usually hit 75-80 for most things. And there are lots and lots of people with the same temps after repasting... and the realistic difference between 85 and 90 isn't much. Especially when you consider that the cheapest lead-free solder has a melting point of 160C, and the tjunction for the chip is 111C.

If you want to void your warranty, go ahead and repaste. If you're confident you're not going to wreck your computer (or break your speakers), go ahead... but if you're looking for lower temps simply because you want lower temps, it may not be worth your time.

So you weigh your risk of eventual (but highly unlikely) heat problems, or immediate warranty-voiding problems.

Or just be careful - there are some excellent guides, and it's not particularly challenging. But again, your real-life improvement probably won't be as much as you think it is.

Edit: both nvidia and ATI keep the memory controller on the edge of the chip, here's a r700 chip shot (the 4870, i think?), just google image search for gpu die, to see others.

 

I took it completely apart last night and had no problems at all, my AS5 should arrive today im just dubious when I reach the motherboard because of the black tape around the two flimsy cables at the top and bottom of the mobo seems like a disaster waiting to happen if I should break them.

Following the instructions carefully I had no problems getting to the mobo and it would appear the tricky bits being mentioned as the keyboard and the speakers cables were not for me I found these the easiest, I am wandering as my G73 is refurbed if the black tape around the cables inside was put on after Asus built it.

I couldnt get the fans out but there was some serious dust inside so even more reason for me to go for a total dissassembly.

My temps while gaming reach around 76 max for the GPU or around 88 for the Mem/io. Its only during a stress test at full burn that I see 92oC (max temp Mem/io) under Burn in and 100oC (max temp Mem/io) under Extreme burn. So maybe I should keep it as it is for now. Never had a BSOD or GSOD.

 

Guys,

Just for reference:

I'm in the UK and had the exact same problem. Still had over 2 years on warranty but was reluctant slightly to send it in for repair due to the not so good feedback from other Asus users who RMA their product.
I bit the bullet and sent it in for repair. Took all of 2 weeks to get my laptop back. Here's what they replaced:

* G73JH VGA BD
* Touchpad for M90
* Bottom case assy

The laptop is in perfect working order once more. I can play Crysis Warhead for hours once more instead of a ty 5 minutes (before it would shutdown previously).

Whether a repast is all that is required is not for me to say but the graphics card also seems to a problem. Cheers.

 

don't forget to check that you are on the latest vBIOS
