I was just playing Oblivion using my new REv 1 7900GS card. It went UP to 92c! I was playing under MAX settings for about an hour. Its kinda Scary!
CAn anyone tell me whats their max temp under Oblivion using FULL settings? A by the way i was using 575/575 1.24v settings too.

Dont have a notebook card with that power, but my 6800 goes into 80c+, and supposedly those gpus can withstand up to 130C before causing instability. I think your fine for your notebook, I would assume notebook gpus are designed to run at higher temps then desktop gpus. Just keep your notebook cool, I wouldnt worry to much unless you constantly start hitting 100C-110C+ all the time.

i constantly hit 104, which under the nvidia thing would be 109. No problemo.

Same, my 7800GTX has hit 113C corrected and would be in the high 90s playing FEAR. I haven't put much stress on it since then, but I have had no problems.

I have an old rev0 version which is a bit hotter than the newer one. Different card, but I expect thermal tolerances are similar.

No need to worry. The 7900GS can handle max 109 degrees, and if that temp is reached, then it will clock itself down.

When playing Oblivion, I occasionaly hit 96 degrees on my 7900GS. Not so strange I guess, as it's clocked to 650 core / 1600 mhz core.

a huge factor is also ambient temperature.

At like 78F Ambient (sorry don't feel like converting my room temp :P), I get like 86C under load of Company of Heroes.

At like 81F (the room w/ computer has poor temperature control), I get 92C or so.


Of course, I'm single piped, no AS5, and running at 594-624/540@1.24v. And as others have mentioned, I believe a lot of these card are meant to run hot. My desktop radeon x1950xt gets to 95C at stock clocks/voltage in a very well ventilated case (2 case fans directly blowing onto the card with the stock cooler as well).

maybe the card is meant to run hot, but what about the rest of the components? the wireless is just under the gpu, the card reader and hard driver are near too... i will try to lower those temps. Its just too much i think. I know that lowering the clocks wont help much, but lowering the settings does. With v-sync i get 10 degrees less (for not reendering the extra 40 fps) and HDR lightning also heats up The GPU.

i have the dual-pipe and i keep the fans on full speed all the time. i was just playing company of heroes for around 1.5 hours and i didnt go over 75C with 7900 @ 575/575. but i use resolution 1200X800 and all high settings which gives good frame rates around 40-50. half-life 2 gives me temps around 80C when playing for more than an hour. but thats with 1600X1050 and everything high.

anyways does keeping the fans on full speed harmful? also yolda does v-sync has any advantage in quality or it just limits the frame rate to your monitors refresh rate.

I think keeping the fans at full speeds is just useless, since the temperature drop depends on the Delta (difference) Temp. So at low temps it wont have a noticeable effect, and may reduce your fans life. v-sync works, by limtting the how many Frames the GPU reenders and sends to the Monitor, This will take a huge load of the GPU and removes the flicker on most games. Its not a good idea on games like SupCom where every Frame counts. and hitting an average of 30fps is a luxury. Having a dual-pipe card help a lot too. I will buy an Pacific-Breeze cooler to see if i can lower my temps a little. Also overclocking the card to settings that give you more power than needed, heats it up for no reason. Why having 53 or 76 FPS on a game if all you need is a constant of 30 fps? I will try to figure out other techniques too.

oh thats great then. i was playing hl2 without vsync as i didnt know what it did. if it takes the load off then its good.
on a side note, i just wanted to say how let down i was with SupCom. i usually play games just for single player and it sucked. on the other had was amazed with company of heroes. even better than cnc3.

Who needs more than 30 fps??

Man it sucks to be me, I can't stand anything less than 45 minimum fps (so average needs to be around 90+), and I can tell differences in fps till around 200 After 200, it's pretty much all silky smooth and I'm happy as a puppy

probably my fps past sigh

I sincerely hope that eye can't tell the difference myth doesn't rear its ugly head once again (fighter pilots can distinguish differences in fps well over 200 (think it's around 300 according to tests where they flashed one frame with a silhouette of a plane on a monitor running at 300 fps and they could tell); tv being 30 frames doesn't prove anything other than there's a reason why tv blurs in action and doesn't look like real life but cinematic).

My 6800 Ultra used to throttle constantly when playing FEAR Combat. I just shrugged it off. I undervolted the card and I think it might be helping a little now. You have nothing to worry about, these cards can take a shit load of abuse. They have the built in throttle for a reason.

I was under the impression the throttle temp for the 7900GS was 102c.

If you guys are getting temps that high I would consider taking the laptop apart & blowing out the fans & taking the time to AS5 the core if you feel up to it.

high temps are one of the leading causes of component breakdowns. Overclocked my 7950GTX rarely ever pulls over 80c even under full load.

Could you make an oblivion test using FULL settings?

81c under max settings. of course gameplay gets a little lagged around enemies @ those settings.

When I used to play FEAR, my 7900 would peak at 92C.

Thats with AS5 and cleaned out heatsink/fan...overclocked/volt modded.

Most modern games that stress the GPU, I run in the 80s normally.

I was thinking about getting this cooler
But the way it works doesnt convince me, since it takes air from the back, and thats where the heated air goes out of the laptop. Any suggestions? I was also thinking about doing this mod, but i tried connecting 2 12v fans using a USB and it did not work as i though. They need more power to work ok. I even tried using 2 USB connectors at once and it did not work.

at stock speeds the stock cooling should be fine as long as you open up the laptop & blow out the fans & HS properly. I think that mod that you posted is a bit of overkill. If you want to really drop temps, apply AS5. It would be quicker & more efficient.

Your suspicions are somewhat founded about the pacific breeze cooler. The lower the temperatures of your laptop the more cold air gets pumped in via the cooler. And from then on the whole temperature - cold air ratio is interdependent. When I have a really clean laptop, the cooler has my right hand freezing near the mouse and is really useful. Despite this whole temperature - cold air ratio, from my experience the cooler always reduces temperatures and even more so when the fans are on.

And as mentioned, with temperatures like that you may want to think about AS5
