My 6800 GT is running at 425/1100 and is watercooled. I use copper BGA ramsinks on the memory.
After 30 minutes of rthdribl i get 63 load on the GPU and up to 58 degrees ambient!
Idle: 46 GPU 40 ambient

I have a silent system but there's 3 Casefans runnign at 5 Volt. The Case itself never gets the ambient temps the card reports. My fear is that the memory is getting too hot.
Is 58 degrees ambient somethign i should worry about?
The card is stable of course.

using smartcooling my ambient is about 52-54'C GPU/42 RAM on ~2500rpm (at 16x1, 6vp, 420/1200). with rhtdribl i can get the temps up to 68'C GPU/high 50s RAM (~3800rpm). i'd say you should be ok...in terms of thermal fatigue its possibly a good thing to have less variation between load and idle. what you refer to as ambient is actually the video RAM isn't it? (is on my card monitors anyway...) this wouldn't reflect the overall case ambient, so of course there's variation there. my case ambient is 30-35'C.

i take it you have the CPU in your watercooling loop, otherwise you'd be at a lower GPU temp.

Yes i meant memory temp. Rivatuner reads it out as ambient but it'S the memory.
Yes i have the CPU in the loop. The reason for the quite high load temp is that i use a 22 bucks GPU cooler. It's full copper but very simple tech. More than good enough though.
I was just a bit worried about my memory temp. Any idea how high the mem temp can go before it gets critical?

off the top of my head, the highest smartdoctor (*sigh* i know...) lets you set the temperature warnings at is GPU:90/RAM:75, but i think the official damage temps are around 130/90...you obviously don't want to be there though (like the athlon xp's say good to 90 but realistically you don't want to top ~65, ideally much lower).

i think at 58 you should be fine.

Waht is the difference between Ambient and GPU temp?

Ambient is your case temp(which can be affected by your house temp)or the temp around the card.GPU is the actuall temp of the gpu itself!

Ambient isn't the case temp. It's the temp around your memory. Under load i have 34 case temp and up to 58 ambient!

Well, in the driver temp it says that ambient is the temp around the GPU.
is that the same?

Yeah that's the one. Can people post their ambient temps under load here please? I use rthdribl to get load temps. While gaming the temps are a bit lower usually.

considering I use 6 case fans, and a cold room for the comp, i usually get 24-25C under load. Usually in a comp, prob high 30's, low 40's would be fine.

I am NOT asking for case tmperatures.

Doh, thats at idle, under load its around 30C.

From nvidia control panel.

Seems like this sensor is useless then. Your temperature is so low beacause a fan (or your general case airflow) is moving air over the sensor. No way the memory would run at real 30 degrees under load.
I have below 30 degrees ambient in my case as well but very high ambient on my nvidia reading since no fan is moving air directly around the nvidia sensor.
The card is rockstable so i think it's fine anyways. :D

Id say slap a 120mm bigass casefan in the front of the pc to push all that bad air out the back end of the case. Plus 120mm are supposed to be pretty quiet. Maybe theres one that runs slower too so its real quiet :P

I wouldn't be too concerned about it. At idle, I get 41C ambient and 53C core. Under a full load (rthdribl) core goes up to 76C and ambient 56C. Havn't been able to get it higher than that except once when playing doom3 my core got to 79C. But I guess Ultras have better cooling than GT's to begin with. Oh well, my NV5 silencer is in the mail and should be here tomorrow. :lol2:

All of you guys have huge ambient temps (on the video card PCB). Mine doesn't go past 43C when at load at 400/1100, this is with a Gainward full copper heatsink (stock). At 425/1200, it can reach 44-45C.. Anything over 45-46C would alarm me for ambient temps.

This is why I'm getting a NV silencer. Although I bet taking of the stock cooler and putting some Arctic Silver 5 in there and removing the pads on the memory would make quite a difference in temperatures.

The ambient temps on my GT were a lot lower than on this NU. My only guess is that the DDR3 memory runs cooeler thus not heating up the PCB like DDR would.
