G51 gpu heat solution?

Hey guys I'm sorry if the solution to this was found but I have been searching the threads and could not find it. Did asus release a bios update for G51s for the gpu heat. Mine idles 64 O_O My G50 used to idle 41 overclocked half way to hell...

 

You G50 also uses a completely different video card.

Don't be alarmed. These suckers run hot, and are built to take it.

 

I know it runs a different video card lmfao I've had it and have been tuning with it for a while. Actually had it pretty equal to a sager np8662 260m (10,550 3dmark) and the high loads never passed 86C (on a cooler)

63 idle is NOT normal for a 260m and this laptop has the same cooling( with the exception of a different spindle design on the fan).
The fan does not kick in untill around mid 70s. A bios upgrade could fix that if there ever will be one

 

Well, a fan mod wouldn't hurt.

But it still stands that higher temperatures aren't damaging to ths computer. While surfing and doing everday tasks (streaming video, music), I'm maxing 60 on the GPU.

Wait no, just hit 61.

 

did u OC the G51?

 

My G51 is actually undervolted.

But remember it's running a X9100 CPU

 

My x9100 never passes 63C on heavy load and idles 35C. A bit more than it did in my G50 but still not as bad as this gpu issue. Max load came up to 95C on 3dmark just now. That is ridiculous. Time to mod this bottom panel as I did the G50.

 

Is that 95 off of stock? I hit 97 with an overclock, no undervolt.

And remember a hotter processor will also effect GPU, at least in these models. The CPU and GPU share the same heatpipe.

 

63 idle is bad. The usually idle around high 40s or low 50s I believe. Thats from a cold boot of course and not after you've used it for a while at which its around the mid 50s.

 

The cpu does effect the gpu heat but not unless the cpu spikes above 70C I noticed my gpu hit 2C higher(on my G50) The piping is seperate running to different parts of the fan module so the effect is very small.

I just turned on my comp and it started idle at 44C and is slowly climbing. After a minute Im up to 48C

Any chance I got a defective one=?

 

Cold booting starting at mid to high 40s is fine for the G51. The mid 60C idle is what worries me. That, I assume, is after some gaming?

 

So 3dmark with the laptop flat on a desk got gpu temps of 95C..after that it idled 60C and now im on a cooler and Im idling 47C..Cpu highest temp was 64C and now its idling 29-30c..

Just an option but I applyed as5 compound yesterday on both the gpu and cpu so maybe there starting to break in now... I know the avg break in period is about 5 days or so..

 

Bump

Back up to 51C when typing right now

 

The temps you've just posted are fine. No need to worry, also you are only allowed to bump every 24 hours I believe since your last post.

 

Keep us posted on how this continues. I'd rather use straight AS5 on the GPU instead of the thermal pad.

 

Gpu heat hit above 100C with the gpu overclocked to stock 260m clocks when playing gta4...Could I be in for a lemonhead gpu here? I really hope not because it would take hell to get a new one out of BB

 

Whoa, 100*C? Call the fire department.

Were you able to apply new thermal paste in the other thread? Are you using your laptop on a flat desk or a cooler?

 

My CPU heat affected my GPU a LOT. Running Orthos to stress test caused the GPU to rise 9c above idle.

 

100C with GTA 4 is not normal. I only get to 93C with higher than "stock" 260M clocks running Crysis with everything maxed out.

Try to confirm the temps again and if it really is that high, you might have to seek a RMA.

 

Should I call BB and try and get a new one...No wait..get a new one.

 

I think it's the same problem G8-somethingsomething had with this GPU.

He removed his thermal pad, put in AS5... and saw his GPU temperatures shoot up.

 

crap,

When i bought mine from xotic, i paid to have them install as5 on cpu and gpu. hope it doesn't show same results.

 

They are very reliable and I have no doubt that they have applied it well.

 

Dude you keep saying thermal pad but the laptop stock does not even come with a thermal pad on the gpu center square..The center is where the thermal paste is applied(where I applied as5). The outer areas of the gpu are where the thermal pads are(all still there). I simply think that the 260ms in the g51s are crap..all of them even though it doesn't make sense. The np8662 260m never passes 83C so great job ASUS! First they pull out the oled, add a new keyboard which is good due to the backlight but also very flimzy, and add a 260m with the same thermal cooling design as the pre-generation G50...not right in my book.

 

No center gpu has a thermal pad though...if someone did substitute paste in the center with a thermal pad please let me know the results and which pad is good...

 

So you have no foam-looking thing attached to either your GPU core or your heatsink?

Odd.

 

What are you talking about the core is where the thermal paste is applied. the outer regions of the heatsink are where the the thermal pads come stuck on stock and should stay there since there is a small space that the pad covers. If you apply paste around the outer parts of the heatsink, the heatsink will not be able to come in contact with the gpu. That is why we put thermal paste in the core square instead of a pad even though it is possible.

 

Wait, I'm not understanding. You put AS5 on top of the GPU core and then put the thermal pad on as well?

 

Your a hard person to get through to . The core is where thermal paste should be put. The outer regions of the video card are where thermal pads are placed. That is how mine is set..with as5 on the core and thermal pads on the outer regions. Thermal paste should not be put on the outer regions since the heatsink sits higher there for the sole purpose of having thermal pads there. The center of the heatsink sits flush with the core which is why thermal paste is applied there.

 

Okay, let me tell you how my mine looked.

When I lifted up the heatsink, I noticed that there is a foam-looking object stucked to where the GPU thermal interface would contact. There is a square-shaped indentation the same shape as the GPU interface.

On the thermal interface, it looks like there's nothing put on there. Well, it's a little bit "cloudy" but no paste like there was on the CPU. Around the interface there's this transparent orange layer.

When I changed out my CPU I didn't touch anything concerning the GPU. But you said you put AS5 on the core, by which you mean that raised metalic square in the middle? And you put you AS5 on the raised metal square, where the foam thing would press down on?

 

For those interested in GPU fan modding, I posted this images before (G1S GPU fan mod)





This is the fan I used, its dimensions (WxHxD) 25x25x6 :
http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=1133175

This mod keeps my G1S alive, GPU temperature went down 8 degrees lower on load, 96C before, 88 current (92 max after an hour of GRID). Idle also went down 6-7 degrees, 60-65 before, 56 current

 

munchkin-man, Forge. A picture is worth a thousand words.

 

Well, I'd take one, but I'd rather not open up my heatsink yet again.

And your avatar just changed.

 

Do you have a link to a picture of the G51 GPU?

My avatar is like a mood ring. It changes depending on how I feel.

 

Unfortunately, no. Tomorrow I might brave opening it up for like the eighth time and taking a snapshot.

 

Predator, I might just do that mod myself also, looks like it works pretty well. My temps keep hitting 100C, even when playing call of juarez...

 

If you have Prototype, try testing that out.

On top of a deactivated Zalman cooler and with a GPU overclock, I didn't break 83C. Significantly higher temperatures might indicate a problem.

 

I found a pic of your GPU. http://forum.notebookreview.com/showpost.php?p=5002686&postcount=261

The transparent orange film is to protect the exposed nodes and resistors on the northbridge since Asus used an unnecessarily large thermal pad. However, you don't need to worry about the northbridge, rather just the CPU and GPU. From skyhawk21's post, he said the CPU and GPU use thermal paste and the heatsink sits flat over the dies. I guess the only option you guys have is to properly reapply thermal paste onto the component dies.

 

Well, I'm officially a fool.

So I had the northbridge confused with the GPU. Lulz all around.

 

Aside from you being a fool, I also noticed that skyhawk21 said he put thermal paste on the die and the face of the heatsink itself. This is a poor method of applying thermal paste and none of you should replicate it.

 

Indeed. I'll try doing some AS5 on the GPU tomorrow, then.

 

I will be placing an order for a spare backpanel for my notebook next week so I can drill some more holes over critical points such as the northbridge, the HDD, the entire GPU daughterboard, and the wireless card. With the heatsink mod that I have installed on my system already, a backpanel mod will make this the true final revision of my cooling overhaul.

If you guys can obtain a spare backpanel for your G51, you can also do this mod as well. More holes in key locations means improved passive cooling and more intakes for the fan to suck air from to improve circulation overall. I better stop by the hardware store and pick up some precision bits.

 

Which heatsink mod did you do? Copper mod?

 

It's worth the "weight" so to say.

I know Orthos isn't as intensive as the standalone version of IntelBurnTest or the one built into OCCT, but Orthos is pretty damn close already. IntelBurnTest only raises my temperature at a sharper rate and flatlines only a few degrees higher than Orthos.

Furmark is just as intensive as the GPU stress test in OCCT.

 

That is a seriously impressive mod.

Where do you get those copper blocks?

 

Would the bottom panel fit if we used those copper blocks? and like greyreap said...WHER DO WE GET IT! lol

 

The key here is ceiling clearance. I don't know how much space there is between the top of your components and heatsinks to the wall of the backpanel as I do not own a G51.

You can find them on eBay.

 

Interesting.

How did you secure them to the components and heatsink?

 

I found copper blocks originally made for a desktop 8800 gpu but they were pretty tall..might have to do some cutting but the clearance is pretty small between the bottom panel and components.

 

I used 8mm, 5mm, and 4mm blocks. Add 1mm to each of those to get the minimum amount of clearance needed to install them.
