G73JH GPU Core temps reading drastically different

Hey Guys,

Got an issue on a G73JH. I had the GPU heat up to 110C and shut down during gaming. ( I know very bad) (Happened just once and this is how I realized I had a bigger issue than I knew of)
I just had the laptop professionally re-pasted by ASUS service in June and noticed that my temps were creeping up. I usually use HWMonitor and the GPU was idling around 78C. Way too hot.

So i decided to open it up and clean the dust out. It wasn't very bad, but needed done regardless. My temps dropped to 72C. Still not very good(at least I don't think so )
So I ran Skyrim again to see how the fans reacted and to see what kind of max temps I would get. This time it did not shut down and I ran in windowed mode to check on the spot temps. As I would spot check the temps, they reported 109C and would drop almost immediately to 84ish, once windowed in HWMonitor. I would alt-tab back to Skyrim for a few minutes and back to HWMontior same think 109C to 84ish. Weird.

So I downloaded GPU-Z. Here's where I start to get really worried.

My GPU cores are as follows...

GPU Temp 1: 61.0
GPU Temp 2: 73.0
GOU Temp 3: 63.5


WHY are my temps so different? Is this normal? I am worried my GPU is dying. I am more of a HW guy and at my software tech limit on what to do next, so what do you guys suggest?

Also, what temps should I be seeing here? GPU CPU?

 

Simple solution is to repaste yourself, properly, using a decent quality compound. There are numerous posts of people having no luck getting ASUS to repaste (end up with high idle like you have) then doing it themselves and getting decent idle temps and load temps.

With a good repaste and ambient of less than 25C you'd hope for idles < 55C max, and a load on furmark of <80C.

A plus for you is now that the machine has been opened down to the motherboard you are less likely to bend the keyboard or pull off the speaker plug!

Your temps aren't really drastically different, when the paste isn't applied that well there tends to be anything up to 10C between the different GPU sensors.. TSS0 is the dispIO, TSS1 is memIO and TSS2 is the shaderIO. (sensor 1, 2 and 3 respectively on GPUz I expect). TSS0 is usually the lowest, I think it is in the middle of the GPU die, and TSS1 is usually highest, which is further to the edge. With a good paste job they are usually within 5C of each other, I know with stock paste my TSS1 was about 10C higher, when I repasted myself the difference dropped to 1 or 2C on idle.

Read all the guides, watch the BTOtech video, and take your time, the result will be better than any trip to the ASUS service centre where they tend to slather on cheap nasty paste!

 

Thanks SpicySi, I picked up some Arctic Silver 5 and repasted tonight. Ambients went down to 58,62,59 and in game maxed at 84, and ran around 75-77 most of the time.
Not exactly perfect, but much much better. The ASUS guys plastered paste all over everything.....way too much!

I tried running FurMark with no luck as it kept crashing. Not sure why, but as long as I'm not killing my card now, it's all good. Rep added....

 

Good job, always good to hear a repaste went well with nothing broken Now it will be a cakewalk if you ever decide to pick up a cheap 920xm to get a bit more life out of it.

That temps not too bad, as I recall artic silver improves a bit over time as it cures, unlike ICD7 and others that give max result right away. It is a crack up how bad the ASUS paste job is eh, why can't they train their techs to do it properly and use a good paste??

Not sure why Furmark would be crashing.. are you sure you have the latest vBIOS and BIOS? Are you on Catalyst 12.10? Sometimes after a machine comes back from ASUS the vBIOS has been downgraded to the original which is prone to GSOD (vertical line crashing due to memory timing mismatch) and crashing with latest catalyst drivers. Check they are both up to date, posts of versions etc are in the "read me first" forum section. With the latest vBIOS the temps for the fans to ramp up are reduced, so the idle and load are lower... so will improve lifespan and doesn't increase noise appreciably.

That's something i'll never understand, microsoft and sony make the ps3 and the xbox 360 and use cheap garbage thermal compound. It also looks like microsoft uses a pad of some sort that kind of melts and cures after first use. It's pretty strange to say the least. Dell and asus use decent thermal compound, it's not as bad as you might think. As for the tech's doing a good job that's hard to say. My RMA experience was terrible and i had to send my laptop back to get the right video card back in it (they had to order me a new one). WIth large companies everyone has a job to do and nobody asks questions as long as it gets done. Of course they all say they're A+ Cert at least but i would bet a lot of them aren't.

ICD actually is the one that cures and Arctic Silver 5 really never does cure. It might get a tiny bit thicker but you can still remove it and smooth it out again, icd becomes like clay after it cures.

 

If you want to send a lappy in for repasting, you are better off arranging for it to go to Fremont instead of the Milipitas facility. I know they use better grease, and do a better job of it.

FYI, my G73JH is still going strong after 2.75 years, and still idles at 47-51C depending on power settings.

BTW, Happy Holidays to everyone
