Asus G51VX Overheating Fixed

To start off, I know the G51 is a little old, but it is still fast enough for most games.

So I was playing CoD 4 and noticed it was getting very hot. At idle, my GTX 260m was @ 58-60C, and after 15 minutes of CoD 4(on max settings) it hit 92C. Which is too hot for me.

To lower temps, you should download powermizer: Powermizer Switch.rar - File Shared from Box.net - Free Online File Storage

Once download, use winrar to unzip it. When done, run the program as Administrator. Click the option that says Powermizer On. Then reboot. From now on, when your not doing anything that requires much of the GPU, it will downclock, thus lower temps.


Then I decided to replace the thermal paste on the GPU. While I was at it, I replaced the CPU thermal paste. I used Antec Formula 5.

Now, after 1.5 hours of CoD 4 it gets to a max of 89C(on max settings), much better. It idles at 46-47C. Although the gaming temps may seem like they stayed the same, I played for much longer with lower temp.

EDIT: TEMPS DROPPED AFTER THERMAL PASTE CURED. I UPDATED THE TEMPS.

 

Better idle temps but isnt the gpu hotter on max load now? you say it was 92c now its 94c with max settings saying it is much better

 

When it got to 92C, that was only after 15 minutes. After I replaced the thermal paste, it got to 94C after 1+ hour. I should have played CoD for 1 hour before I replaced the thermal paste, it would have probably hit 99C after 1 hour with stock thermal paste.

I think the thermal paste cured! Idle is now 48C. I'll post CoD 4 results later.

 

CoD 4 Update: I played for 1+ hour and it hit 91C.

 

Now do some hardware mods and vBIOS voltage changes, and you could idle in the mid forties and max out at 86C*.



* Ninety minutes of Crysis Warhead, last two levels, everything high except for very high objects and textures, and medium shaders and shadows. Ambient about 83-85F. Passive cooling with Xpad. GPU at 580/1450/870

 

I did the backplate mod, cut a big hole and placed a mesh/filter on it and changed the thermal paste (AS5). When i played SC2 before or ran the ffxiv benchmark, i would hit 102c in no time (with laptop fan), now with my fan and the mod, i have hit MAX on the ffxiv bench and an hour playing SC2 was 90c. Is 90c THAT dangerous? Is it dangerous enough to warrent me to do a vbios voltage change to the card?

 

i dont think 90c is too hot in that sense. even my 9600m/ quadro 770m card runs that hot. although i dont lik eit cos its supposed to be aaround 80c in my notebook but i no games vary temps. more than say 93% is too hot. i wont fid out for about 2weeks till i get mine and im unsure what to expect or to do cos i dont really wanna drill up my notebook

 

I don't get worried until it hits 97C.

 

well i went ahead and did the voltage mod and now 10 min into furmark max was 94c....im pleased

 

How hot did it get before voltage mod?

 

furmark - before - 106c
- After - 94c

3dmark06 - before - 102c
- after - 72c

Final Fantasy xiv Benchmark - before 99c
- after - 81c


The voltage mod helped BIG time for me

(these were temps before and after i did the backplate mod, new AS5 and voltage mod)

 

Thanks for mentioning this! My gpu was at 90C while idling so I tried this and it lowered the temp to 72. Much better than before.

 

Wow, that sounds hot! Have you tried cleaning the fan/heatsink out?

 

No. I don't have any experience messing with laptops so I was looking for solutions that didn't require me to open it.

 

You may want to take it to a PC shop or the Geek Squad to clean it out. You can't stop dust build-up, you have to clean it every 6 months or so.

 

its not really a big deal. i dont even take the fan out when i cleaned another notebook as taking it apart is not really my thing. but i blow the fan out and then the dust comes out. i have seen the idle temp drop around 10-15c back to 44-47 idel but thats in my quadro 770m. i will treat the principles the same on the same notebook g51vx. my idle temsp are 49-51c but mainly 51c. no paste or etc been added to cool it or a cooler. and my home is not cold lol.

 

I checked out geek squad and they wanted $100 to do it. Hopefully I can find a local shop to do it cheaper.

Did you use compressed air to do it?

 

Compressed air is the easiest way. I'm to cheap to buy compressed air, so I use my dads air compressor

 

Lol, air compressor
every day before I start my job, I hook up compressor to power, Open the plug and let all of the water from the tank to escape, I wouldn't let air compressor anywhere near a laptop, small chance something might happen but better safe than sorry....

 

Did you have to remove a bunch of pads from the heat sink of the GPU when you put on new thermal paste. I took my laptop into a local computer shop and the guy said that I would be risking higher temps if I got him to remove the pads and put on thermal paste.

 

I have heard many people say NEVER change out thermal pads for thermal paste. I think it could fry something. You can buy replacement pads online or do what I did and be very carful and re-use the old ones.

There are no pads on the GPU heatsink itself, only on the memory chips.

 

I shall have to look into getting that done then. Temperatures right now are a bit scary while gaming, GPU reaches something like 103C after playing Borderlands or RE5 for a while. Although thanks to powermizer switch idle temps are much better .

Got the thermal paste redone on the GPU and CPU. Ran the RE5 benchmark before the re-paste was done GPU hit 103C, after thermal paste was done max temperature is 88C!! I guess hard thermal paste doesn't work very well lol.

 

I have the Asus g72 as my sig says and a couple older g71. They all run the gtx 260m Cuda 1gb ddr3..... so far 3 of those cards have died... but not one of them reached temps higher than 99 deg C. I never overclocked them or modified anything on them. I also made sure they are dust free. That being said After ASUS replaced the gpu on my G72 last week the normal temp of the Gpu is about 50-55 deg C. But they seemed to have messed up on the heatsink for the cpu now the cpu hits 89 deg C!!!!!!..... and I have not taxed it yet.

 

You should try to either re-seat the GPU, possibly voiding the warranty. Or game on it for a few minutes until it burns up, and have Asus come and fix it again. I'd try the later.

 

i got g51 jx model.
and i'm very disappointed about that laptop.
i play normali wow on full hd with low settings and the gpu reach 105 degrees
i don't want my laptop to burn like hell
i've flashed to recent bios 208 and installed recent video card driver but nothing happen
the only solution seems to give to the warranty ... or any one got a working solution?
i've purchased it on march 2010 , and i use the cooler master pad .


if after the warranty repair it will continue to overheat i will sell it to ebay and buy a mac that really don't have those kind of problem because they TEST product before sell.

 

105C is actually "normal" for that GPU, but it's close to the temp where it will start throttling. You can check your fan & blow out the vent area with compressed air, if that doesn't work you can repaste your GPU, but not if you are under warranty.

Any intense game with full settings will run your laptop hot -- any system will have this issue if you push it to its limit, including the new macbook pros.

 

Um, "105C" is definitely not nor normal, where did you get this information?

 

For a 360M it's not a dangerous temp. It's about where it will start throttling, but not where it's going to shut down.

 

I believe 105C is dangerous for any video card Nvidia or ATi. Just because it doesn't downclock until 105C, doesn't make 105C safe.

 

NVIDIA presets the thresholds, so if it's downclocking, it's reached that temperature. 105 is close to that (I think the exact tripping point is 107 or 108), it's not something you'd want to do all the time. In practice you shouldn't easily hit these thresholds, but it's possible when stress testing or running a demanding application. In terms of what is "safe" or not, prolonged use with high temps can lead to less longevity, but the card is designed to clock or power down if it is in immediate danger.

Also, the maximum temperature depends on the manufacturing process, so there's no way to easily equate cards on different nodes.

 

Hi. I'm new here and got a G51Vx-RX05 about three weeks ago and my idle temp was 85c and max was 115c within five minutes of NFSW on med at stock clocks and all stock parts. so then I shut down the laptop, grabbed some compressed air and cleaned the duct out(there wasn't much dust) and now its 72c and 99c is that a good decrease? from what it seems is thats a fair reduction but I'd like a second thought.

 

99C is way to hot.

Did you take the bottom panel off when you used the compressed air? Really, idle should be no more than 50C for the CPU and GPU.

Here's what I'd do:

Take the bottom panel off.

Remove the heat sink from the CPU and GPU. This will give you full access to the fan.

Clean off all the old thermal paste(leave the thermal pads in place though).

Apply some new thermal paste, I used Antec Formula 5(Cheap and works well).

Re-assemble. The CPU now should idle in the mid 30's and the GPU in the mid 40's.

 

Yes I did remove the bottom panel.

The CPU sits at about 50c, just the GPU was worrying me being at 75c.

Thanks for warning me, I'll be getting to that asap

 

Is it 75C idle?

 

Yes, The GPU idle is 68-75c CPU is 50-57c

Under load :GPU is 80-96c CPU is 60-72c

I ordered Arctic Silver 5 because it worked wonders for my old laptop

 

Sounds good! I read somewhere that Arctic Silver 5 and Antec Formula 5 are the paste, just different name.

Let us know how it works.

 

Sorry, I'm such a noob, I forgot my password ^^
So I took a part my laptop to find the the stock paste crusted on the GPU... which sucked to get off.

Idle: CPU - 40-52C, GPU - 64-69C
Load: CPU - 54-62C, GPU - 77-89C

So it help just not as much as I thought it would :/

 

That's actually pretty good. Before, you GPU was hitting 96C under load, not it's only at 89C. 7C difference is excellent in my opinion. And, overall your max CPU temp dropped 10C. Good stuff.

 

um yeah my g51vx gpu runs at 110*c im asuming thats bad. what should i do to lower temps? thermal paste?

 

Start by cleaning the heatsink with canned air, then if that doesn't fix it, you can consider a repaste.

 

Ok if I wanted to repaste it what are the steps to taking the heat sinks off the gpu and cpu

 

You have the G50 disassembly guide available here: http://forum.notebookreview.com/asus/122632-asus-info-booth-read-before-posting.html#disassembly. I'd check if the layour of your laptop is similar, it could be of help. Couldn't find a specific G51 disassembly guide.

 

Yep, layouts are the same. I've owned both.

 

Hmmm.. I've tried taking off the bottom cover and that seems to work just fine. I usually hit around 100C while gaming, but the laptop is 2 years old now and everything still works great!

I'm also hitting 2.3GHz in overclock on the FSB of the p7350.

 

Realize this is an old thread, but figured I'd share my experience in here for whoever stumbles onto this thread on Google in the future.

My G51 did not get to the point of shutting itself off due to overheating, but I definitely was getting there. To be honest, I hadn't really been worrying about temps to much, until a few weeks ago I'd boot up Skyrim, and the FPS would drop after playing for only 5 minutes. After downloading a temperature monitor, I found out that the GPU was hitting the throttle temp (108 degress) . My laptop was also idling at around 85 degrees; fan would go into max speed to bring it down to 80, then it'd slowly climb up, force the max speed fan, rinse and repeat.

Not being too familiar with the hardware of these laptops and how to apply new thermal paste, I wound up doing what I could to see if it brought the temp down.
I bought a can of compressed air/gas and opened the laptop up. The fan was pretty dusty (first time cleaning it in nearly 3 years of ownership ) so I wound up spraying some air directly onto the fans (kept the center of the fan anchored with my finger so the blades wouldn't start spinning like crazy when I did that) and also in the direction of the vent on the left side of the computer (I could see some frozen dust fly out of it). For the latter, it probably helps to get a compressed air can with the straw nozzle, as you can use it to get between the fan blades to blow towards the vent.

Lastly, I also invested in a laptop cooler (specifically, the Cooler Master U3). Only about $20 or so on Amazon, so I figured why not. One thing to note about this cooler is it's a bit smaller than the G51, but I found it works just fine with the right side of the laptop hanging off the edge (from my experience, it's only the left side of the G51 that seems to build up significant heat anyways).

Between both of those my idle temps have dropped to 64-65 degrees and I can play Skyrim for hours now without throttling (haven't checked the exact temps during gaming yet). Instead of constantly hearing the fans go in hyperdrive even while not gaming, I only rarely hear it during longer gaming sessions now.

Overall, I'm pretty happy with my results. Had the G51 for over 3 years now and am glad I was able to get the temps down significantly relatively easily (at least for now )

 

why would u be so quick to be like 105 is definitely not normal. yes in as temps go 105 seems pretty dang high for anything but notice he did say for that gpu.. anyway I have a asus g51vx as well .I did some self fan repair and repasted my heatsinks and cleaned all dust...anyway I have been regularly monitoring my temps recently and the new star wars games can bring the temp from ~85C up to ~95 to 99 with a quickness..I'm talking a matter of seconds or so I was worried of course it looked very high to me.. I even saw it get to 100 and 101 but went down quick...one reason I didn't completely freak is because I noticed the variable fan didn't even spool up and get loud until the temp got around 92 or so and was max spolled up at the upper 90's or so. Anyway I just found this page GeForce GTX 260 | Specifications | GeForce and 105c is the max temp for this gpu I am glad I have never seen mine get above 101 of course but what does get me is that I have noticed certain games where the temp will make wild swings from the low end like 83 up to 98 in like 2 seconds then the fan will kick and it will go down..I am seriously considering cutting the speed control wire on the fan to try to get more consistent temps.(this will run fan at full speed all time I guess I could handle the extra noise) (speed fan couldn't control it so I'm suspect this fan is not capable to be controlled through software?) Could anybody tell me if these wild swings could just be normal. Also it just seems to me the wild swings would cause more wear in tear then if the temp could get up to like say 98 and just stay solid sorry for such long post would like to hear some feed back on some of these temps as this is my first experience with monitoring temps regularly and this is the only gpu I have any experience with. or could anybody else with this gpu let me know if they notice temps jump big leaps at times? also just fyi the min I have ever saw so far is 73c and the max I've ever seen was 101c which it would not hold for but a second then start on a downswing hopes this helps anybody else with this card

take the bottom panel off of course and once u remove the six screws on the 2 heatsinks the fan heatsink assembly is ready to be removed don't be too scared to use a little muscle ..just a tad but don't worry it is ready to come out.... it might be a good idea to oil ur fan bearing as well even if it's not making any noise or anything because it's so easy and if it does go out later down the road u will be doing this all over again. I've had my laptop for 3 years and my fan started making noise a few months ago and it just kept getting louder and louder. That's the reason I had to repaste actually, I wasn't having any heat issues just couldn't stand that annoying fan noise but just a dab of some lubricant (don't use WD40 it will work but there are oils that are designed for jobs like this and will do a better job) on that bearing and retape it my fan is quiet as a mouse now.
hope this helps someone

the lowest temp I have ever seen on mine was 73c mine runs up and down 90 to 99 while gaming so far as much as I've learned about this card these are normal for this card...

 

105C is the danger zone where the device self throttles because it is in danger of being damaged. No device should read 105C ever. Also prolonged running of 80s-90s will kill the service life of any GPU. These are "normal" temps for a G51 because ASUS was retarded and designed a crappy cooling system.

 

I've never seen conclusive evidence proving that 80C-90C will kill a GPU.

I mean, look at the MBP 15. The 9600M easily hits 90C-100C, yet there hasn't been widespread failure.

Conclusive evidence? ok...

So many Nvidia chipsets failed due to heat and leadfree solder that the insurance company for Nvidia filed a claim against Nvidia.

Most of my computers idle about 110F cpu and 130F gpu, if they don't then i will modify them. That G51vx i bought had a dead gtx260m and i reheated the chip correctly with my machine and was able to bring it back to life.

This is the result from that. You can also read all of the problems with that particular laptop and how to go about optimizing your temps without modifying the software (if i had modified the software it would have ran even cooler).

100C is too hot for any gpu (my 3 hd radeon 5970's run at about 80C under full load without maxing the fan). Your computer is going to die if it constantly hits 100C.

 

That was because of faulty solder, not because of the temps.

Notice that none of the GPUs with good solder die because of 90-100C temps.
