Topic: GPU temperature comparsion for fun! (Read 683 times)
My 2 x 7950's run at a steady 69C and 60C, clocking up about 1,200 kh/s with no overclock/voltage etc
Whoa that's some hot memory. Have you ran VRM at such temps for how long and/or before with other cards? Somehow this made me think that BBQ Coin should have had temperature as a factor to diff.
The 7970 has run pretty constantly for 5 days, the 7870 for 10+, with a few minor interruptions when I've decided to play with cgminer and options rather than let gui-miner run them. Not sure how long the 110C episode was - I normally check on the cards with GPU-Z a couple of times a day, and now especially after playing with cgminer because of the 110C event!
Have both at -5% power from Catalyst options, but this didn't seem to affect hash rates, temperatures or voltages.
I run a 7950 with autofan that seems to target 75C
1 x 7970 running about 645Mhash:
1125/1000
GPU 71 C
VRM1 94 C
VRM2 62 C
fan-speed 55%/2552rpm manual setting. Can drop the VRM to 88C with 60%. On auto fan, lets the VRM1 temp go to about 110C.
1 x 7870 running about 420Mhash:
1160/1200
GPU 69C
VRM 79C
fan is auto, running at 50%/2050rpm.

2 x 7950s (stock clock) running 24/7 operate at about 73-75c with fans running around 60%..
Haven't had any overheating problems yet

i have a lot of 5870s with the coolers replaced with artic acelero coolers, which are near silent.
have one clocked at 990,330 and can manage 62C, have another that can just manage 900,300, temperature at 79C..
i think it's really down to luck.
thanks,

It's a power sucking beast, I think I may have to look into selling it for a 5 GH/s ASIC miner sometime soon, with summer coming and stuff.

Might as well as my voltages to it as well as hash rate producing at the temp if you dont mind
EDIT:
I don't like my cards hitting 80C so i try to keep it below that by opening windows or turning up the fans speed or what not.

I thought about adding those too on the questions, and now i'm gonna do it. As I was contemplating on it and the first person to answer came to the conclusion of adding them.
Nice figures you got there.

3. Avg. temperature
->83C
4. GPU fan speed
->~2000rpm
5. I have ran it mining as above for over 48 consecutive hours
->Yes
6. The highest temp i feel comfortable
->88C
7. Hashrate/algorithm
->370Kh/s/scrypt (per card)
8. Voltage
->1.21V
I imagine we coinheads have at least as many OCs and tweaks applied to our beloved GPUs as the more so serious gamers.
One thing that pops up frequently is the anxiety of how high temps can your GPU handle and what should be considered for safe limits to the chips. I for one am not comfortable if the temp exceeds 88C.
So i thought we might collect some info here and post our heat levels and possible OC's below.
If you wish to use the same format as you answer it would make it much more easier to browse the results itself, so if possible do so and put your comment under the stats.
PLEASE DO NOT SUBMIT TEMPERATURES AND FAN SPEEDS ON A MINER THAT HAS NOT BEEN MINING FOR AT LEAST 4 HOURS FIRST TO WARM UP.
Edit: Added hashrate and voltage to the questions. And if you wish to share your cooling setup, please do so in the commentary. Mine are stock-cooled and on a open rig with 2,5inch pcie-risers.
