when i play games, and specially demanding games my gpu gets hot. Now, whats a safe max temperature it can reach? Mine on average gets to 83 c... is it safe??? Should i turn my gpu fan to max if it gets that hot? Some insight would help.. Thanks!

What games do you play when it reaches 83 c, just curious :)

I avg 75C after 4hrs+ gameplay of COD Ghosts, BF4, Lords of shadow 2
and 79C after 2hrs of Crysis3/bioshock infinite
Are these temps safe??? (they are gpu temps)

I have G750JX-CV069P

crysis, and metro last night... titanfall also, after a while.. if i turn fan to MAX it goes around 70 c or lower....

Which model G750 do you have? JW/JX/JH JM/JS/JZ ?

G750JZ with I7 4700 2.4 ghz, and 880m 4 gb vram

I haven't worked with a JZ yet, and not many reports are in yet, so I can't say whether that is normal or not.

When I push my G750JH GTX780m to 100% utilization, I see 89c. Normal gaming use I see 65c-75c.

But gaming temperature readings are variable depending on the game intensity and playing intensity, it is better to get a benchmark that heats things up to a measurable load utilization and a consistent re-createable level and then you can run that test on other machines and compare.

Let's try Furmark:
http://www.geeks3d.com/20140313/furmark-1-13-0-download-gpu-burn-in-stress-test-opengl/

The newest Furmark interferes with the Asus GPU Tweak tool monitoring, so I switched to the Built-in GPU Shark monitoring with Furmark.

Here are the results of about 5 minutes of a 15 minute run on "Burn-in benchmark 1920x1080 15min", while also running CUDA processes, to get the utilization up to 99%, The GTX780 is OC'd to 932/6250

36005

36006

I get the same 89c max temp, at stock speeds, without any additional CUDA jobs running:

36007

I quit and restarted Furmark and GPU Shark between runs to reset the max/min readings.

What do you get when you do the same on the JZ?

Two runs, a Furmark run at stock speed, and a Furmark run OC'd through Asus GPU Tweak Tool for Laptops would be nice - and what values for GPU/memory speed shown in GPU Shark. I use built-in Windows 8.x Snipping Tool to grab dialog shots.

SO ITS NORMAL then i guess... thanks!

If you do the Furmark runs for comparison, we will know the max temp, as the gaming temps you are seeing might not be at 100% utilization. The temps you are seeing are higher under gaming than I see. The 89c reading I am showing is for a 5 minute run at 99% utilization.

Reload the page, and read my previous post, I updated it :)

looks like im doing good.. didnt go above 78 c after about a little over 5 minutes...36008




ALSO FAN IS RUNNING AT STOCK SPEED during this test

That 78c is too low, at 99% utilization you should see at least as high and likely higher than your 83c gaming reading.

Check to make sure the Nvidia GPU 3D Program settings are set for Furmark to use the GTX card, and not the Intel Graphics. You need to force it to GTX mode. I don't have an Optimus G750, so check the settings others have mentioned like Adaptive => Performance - etc - to make sure the GTX card is used 100% of the time during the run.

how is low bad? Lol trust me its the 880m i already disabled it the other day XD cause i didn't like the switching.. im guessing the 880m just run cooler then 7800? Its like the I7 processors are designed to run super hot.. or was that core 2 duo? my CPU idles between 35-41 c i appreciate everything sir :D

HomieOC, I am not comparing your 78c against my GTX780 89c, I am comparing your 78c against your other reading of 83c - it doesn't make sense that the stress test of Furmark at 99% utilization is reading less than the gaming temperatures you are seeing.

There are individual Program settings, besides the Nvidia 3D global settings, in the Nvidia 3D settings panel. It is the Program Settings tab, and select Furmark from the drop down. I don't know the optimus settings, so you will need to interrpret the options to make sure the Nvidia GTX card is selected / favored.

Unless you already set the Furmark application settings, or applied the Geforce Experience Optimized settings for Furmark, you are still at defaults.

From other threads, there is no way to force GTX on all the time for everthing, so I am thinking some additional specific application tuning is going to be needed in addition to what you have already done.

oh thats because i ran it for 5 mins i think haha. it slowly goes up over time.. like over a hour.. i'll go play titanfall right now and be back in a little and let u know the temperature at stock :D

5 minutes should be enough to get the temp maxed out.

Did you run the "Burn-in benchmark 1920x1080 15min" option and interrupt it with an ESC after 5 minutes?, or did you run the "Benchmark Preset: 1080" run option?

When I run the "Benchmark Preset: 1080" I see 80c, and 2160 score at 26c ambient:

36011

36009

When I ran the "Burn-in benchmark 1920x1080 15min" option and interrupt it with an ESC after 5 minutes I saw the full 89c

36010

Try doing the 15 minute Burn-in run for 5 minutes, and get that temp reading, or run for the full 15 minutes - I will do the same.

HomieOC, I ran the full "Burn-in benchmark 1920x1080 15min" test, and see 87c, here is the result of the run at 26c ambient:

36012

Now in the nighttime, when the ambient dropped to 22c, the run completed faster and cooler, 82c

36036

yeah i ran same exact as u did ! also i just finished playing... the max temp my gpu got after a hour in titanfall was 81 c... i averaged 78 c though in titanfall. maxed out,1080p.. i get 83 c in crysis and metro.. I think my gpu is fine XD dont you?

Looks good :)

What are the performance result for the 1080 short test and 15 minute tests?

i have no clue lmao!! i didn;t look at that. just temperatures... the 880m and 780m are about same speed.. very little difference im guessing from benchmarks ive seen.

It would be nice to know, please run the tests on the JZ and post the results.

The screenshots I posted above are my results for the runs I did for you on the G750JH GTX780m at 932/6250.

Hi all!
I have the same thing as HomieOC. I run Metro Last Light and after about 10 min I see 83C GPU temp, however when I run Furmark 1920x1080p 15min burn in benchmark, I only get 72C after 15 min of 99% GPU utilization...weird.

ps: I am sure that Furmark is using the GTX 880M because the right fan gets louder and GPU-Z shows the same temp for 880M as Furmark.
