Very Hot GPU (>95 Degrees)

Hi All,

For a few months now, I've been experiencing slowdowns (from an FPS of a steady 60 to 7 FPS) in games (such as CS: Source, Civilisation 4, AOE III, pretty much any game I play) after an hour or so of gamplay (it varies depending on how long the laptop has been turned on for, leading me to believe that it was a heat issue).

I downloaded the nVidia tools and left my laptop off overnight. When I booted up the machine the GPU was reporting an idle temperature of 88 degrees celcius! Not less than three days earlier, I took the back plate off my Asus G2S and cleaned what little dust there was out of (what I'm pretty sure was) the CPU fan. Is there a GPU fan and if so how do I get to it?

I'm currently running 177.70 drivers from LV2GO, although the problem occurs on the stock Asus drivers (101.34 from support page). The GPU is running at a core speed of 475mHz and a memory frequency of 702mHz. Under load (using the NVTOOLS stress tester) brought the GPU to a temperature of 99 degrees after five minutes). I'm no expert, but this seems pretty high.

I purchased my notebook at the end of August of last year, and have only been having this problem for about a month. About a week ago I performed a fresh install (complete nuke) of Vista using the supplied recovery disks, however the problem still exists.

Does this thing need to go in for repairs, or is there something I can do to stop the problem?


EDIT: I've done some further testing in Civ 4. The slowdown occured after about 15 minutes (the laptop has been running all day) of running the game. NVMONITOR reports a GPU temp of 107 degrees celcius at the time of the slowdown.

EDIT: Slowdown in CS: Source as well. GPU temp at the time was again 107.

 

Send it in for repairs to find out the problem while it is still in warranty.
If its faulty parts, they will replace them (if under warranty, else you will have to pay for the parts).

 

So this is not normal then? Can someone with a G2S confirm their normal operating temperatures (e.g. web-browsing), then the temperature when the notebook is running a (ideally new) game?

PS: I'm still under warranty. Will be for another 13 months.

 

My G2s (bought in may of this year) gets idally about 75 degrees and while gaming max 92 degrees.

while overclocking (600-1200) it reaches 100 degrees

 

clean the dust inside, I am pretty sure that's why.

 

Interesting mine used to downclock before reaching the 100s, not it doesn't even reach the 90s....

 

Wow, mine's running hotter than yours and it isn't OC'ed. And isn't 600/1200 a pretty heavy overclock (26% increase in core frequency, 71% increase in memory)?

So your G2S is downclocking you in the 90s? What are your normal operating temps?

I have... I can't get to the vent without voiding the warranty, but I have cleaned the (only) fan. It seems there's some copper bars that bring the heat from the GPU to the fan.

 

The Gxs series are notorious for running very hot.
According to ASUS , 90-95C is normal under full load.
Check out my guide , link in sig, you`ll definitely lower the temps with undervolting and raising the back of the laptop.
