G series overheat problem

i'm reviewing and willing to buy either G51VX-RX05 or G71GX-RX05.

i already knew when it comes to portability the G51VX-RX05 is better choice.

but it seems two of them have the same problem: overheat problem.

how to overcome this? did Asus already resolve this matter?

 

The G51 does /not/ overheat. It gets hot, but there are zero performance issues.

The G71 doesn't overheat per-say, but after putting the beast to sleep, upon waking up it will throttle after a certain mid 80s temperature.

 

ok it doesn't overheat, but it tends to have high temp.

is it harmless for the 'hardware' and the performance?

 

its harmless for the performance, but since they are such recent models we have no real proof to show for or against the hardware damage possibilities. There have been no reported heat related failures that I am aware of.

 

I don't even get high temps. I run around 45 idle and I get up to 60 or 70 under load.

 

nice to hear that..

i become a bit paranoid when it comes to heat problem.

 

It seems like the heat problems with G51s are hit-or-miss.

I've had no problems, and neither has my brother, but we know some people who do.

 

I got a G60(same as G51) a few days ago and some components do get hot (GPU) but it has excellent performance.
I mostly noticed high GPU temps only when running some benchmarks and tests but during hours of gaming GPU temps never rose above 83c.
Here are some benchmarks I ran.
3DMARK 06 was run at the G60 max res and OC'd the CPU in Power4Gear Extreme Turbo mode.
I did install a T9900 and used IC7 on the GPU and CPU
Run 1 Stock GPU
Run 2 Slight OC GPU
Run 3 Higher OC GPU
Now I probably could have OC'd the GPU a little more but at those clocks my G60 ran extremely stable and kept temps under control.

 

You also have a pretty much guaranteed 2 years out of your machine with the free asus warranty *edit* IF you get a non-best buy model.

 

So what!
That's the price I have to pay when I wanna play

 

really?

but is it safe to have the temp above 80c?
it won't shutdown automatically?

 

No, it will not shut down even at 100C. It won't shut down til I believe, 108C.

 

But if you go anywhere near 95C, you should be thinking of ways to keep your laptop cool. 95C might not be insta-fail dangerous, but it's not healthy no matter how you slice it.

 

Just ask Sach, he has dreams about his GPU failing.

 

Well G51 i think has a 105C or around there shutdown or downlcloak measure. But i havent seen many games that will make it go above 90C.

Well i would say anything lower than 90C should be fine, but not all GPU are the same, Asus also designs their own setup (dont use the standard), so it might be built to be able to stand above specs, now this is speculation by my part, but still things can be design to stand more or less what the standard can handle. I yet to see problems related to heat into the G5X/G7X series.

Now if you are worried about a laptop runing hot, then look to Sagers they usually have better cooling setups but you will have to pay for this as usually more expensive than Asus laptops.

 

Or you can invest in Bergquist bandaids, copper blocks, thermal paste, and a drill.

 

but unfortunately Sagers is not a common brand in Indonesia.
i won't be able to get the after-sale service for it
i think i would still go for G51. i've been falling in love with it

it seems so.. thx for the suggestions all

 

I noticed you're running driver 186.40 How is that running for you?? I'm running 186.82 and it works great. It was the latest I could find that throttled correctly. But it doesn't allow LCD brightness control. So I was wondering if 186.40 works correctly in all aspects?? Does it throttle correctly? Does the LCD brightness change when you choose battery save mode or by pressing Fn F5 or F6?? I'd really like to regain that control and have it throttle correctly while still having performance and stability.

thanks

186.82 allows LCD brightness control for me.

 

hmmm.... maybe time for a reinstall.

 

you can go to singapore and purchase it..
theres a local reseller there....
i got mine from there..
pm me if youre interested

 

Just using the drivers it came with and yes everything works great.

 

Did you have to use Powermizer Switch to get it working?

 

My G51J hits 97C playing Crysis for 10 minutes at 1920x1080 medium settings (75C ambient temps, no cooler). I just ran Furmark again and it rose to 102C and was still rising about 1C every couple minutes. I shut it down at that point as that's just too hot IMHO.

I did opt for the ICD7 from my reseller, so I'm admittedly surprised I'm getting temps like this. I know its known to run hot, but this seems hotter than what most people are reporting. Idle is 61C after just a few minutes after quiting the game, which is ok I suppose and it does drop there quickly (I just checked these temps after playing tonight). I really worry about temps during the summer, though. I've also gotten some blue screens, too, but I don't know if this is related to the temps or not.

Since I just received this laptop this week, I'm debating whether I am going to keep it or not. Something of a bummer.

Performance wise, it's quite nice. I really like everything else about it (save for the weak speaker volume).

 

Get what working?
But no, not using Powermizer

WOW!
Those temps are real high.
When I put IC7 on my GPU and CPU I noticed right away that the old stock thermal paste on them was not good and didn't cover the whole GPU.
The lower left corner was not covered.
I don't know exactly how warm the GPU ran with the the old thermal paste.
First thing I did when I got it home was to install the T9900 and add the IC7 on the hardware.
It is strange that even with IC7 your GPU runs that high but I would call the reseller and ask what's up.
Those temps are not acceptable.
The highest temps I have noticed in gaming was 84c (yes even in CRYSIS) and that's after a few hours of gaming with the CPU and GPU over clocked.
In Furmark benchmarks temps did go as high as 91c but that's it, ran for 600 or 700 seconds and stabilized at that temp once the fans kicked into high gear.
But I only get 91c when running Furmark while gaming it's much lower.
Good Luck.

 

It sounds to me like it might be a bad paste job.

 

I'm thinking the same thing but I can't do anything about myself and not void that warranty. If I send it back for a re-paste, I have no way of knowing they will do it right the second time either, if that's actually the problem.

This really stinks. I thought by purchasing the ICD7 I'd be set. Now I'm starting to think that if I send it back, I'll probably look to a different notebook. Possibly a Sager 8690.

 

Yes, send it back.

 

Get Powermizer working of course.

Put up a screenshot GPU-Z and Hardware monitor at your desktop idle (doing absolutely nothing) and we'll see what your temperatures and clocks are.

If they are not 200/120 (Core/Shader) then your Powermizer doesn't work either and your GPU is clocked at gaming speeds at all times, even when it is doing nothing.

 

As much as I like the notebook, that's what I'm going to do.

I've seen a few of your posts describing the application of TC and I thought I'd ask you about what the tech told me.

When buying the laptop, I spoke to one of the reseller's techs about the TC options. During this conversation, he mentioned that the application of ICD7 was a little different than AS5. He said with ICD7, it needed to be applied as a dot instead of being spread and this was because of the nature of the TC.

I bring this up because it seems contradictory to what I've seen posted here as well as my own experience in applying AS5 to desktop processors. I've always used the "spread a thin layer with a card" method and have never had trouble, but I have no experience with ICD7 so I figured the reseller would know best.

In fact, I suppose it's hard to tell if the purchased TC was applied or not, since you void the warranty by removing the coolers. I guess you have to just trust the reseller. I haven't looked, but apparently they replace the "do not remove" sticker, or so I've been told.

Now, since I'm having thermal issues, it makes me wonder if it really was applied correctly or not. This is why I hesitate to send it back for a re-paste because I may just end up with the same situation.

On the flip side, I've seen several great comments about the Sager 8690 and it's thermal performance in particular, so that may be the best way to put this whole thing behind me. I just hope the Sager is as nice overall as the G51J is, or better yet, nicer.

Anyway, I've opened an RMA for a return and it ships out tomorrow.

 

That was the key..Thanks!! I got 186.40 to work (which gives me lcd brightness control along with auto brightness control with different modes Battery etc..)

But it didn't downclock. Which I wanted. Don't want the thing running at full clock while doing email and work.

So I changed PerfLevelSrc in the registry from value = 2222 to value = 3333. Now have everything I want.

Thanks for the tip

Welcome to the KGB.

 

it DOES OVERHEAT! try this test Core2MaxPerf ( http://www.withopf.com/tools/cputempwatch/ ).

my g51j shuts off after 20 min with High Performance in Power4Gear and Turbo Mode set to OFF!

and this program tests CPU only! i don't wanna imagine what i get if i test GPU... It will explode
