I still think of it as a badge of honor(or stupidity)but 2 weeks ago,I left for the weekend with my Gigabyte 7950 running at 102 degrees.
And yes,it survived.
Now that I've learned my lesson,I'm running both my 7950 and 7870xt at 70-80/60-68 degrees,depending on whether the ac is turned on.
Topic: How hot do your GPU's run? - page 2. (Read 7693 times)
I'm running 2 Sapphire 5870 1GB. GPU0 and GPU1 undervolted at 1.150v and 1.175v.
This lets the top card run 5C less hot, and both are running at 70.5C.
Pretty decent overclock on both cores at 960 MHz and both MEM underclock at 300 MHz.
Getting a stable 427 MHash/s on each in cgminer.

i never let my cards go over 60c core 80c vrm 7950 vapor x 55% fan max air output temp 38c air intake maximum 30c
i run my rigs in boxes not crates ( i have 20 rigs of 4 7950s and 1 rig with 3 ) geting 630kh / card at 1050/1250 at 1.050v ( 875-950w /rig )

damn thats a lot of 7950s
what type of 7950 do you run?I have the plain old cheap sapphire 7950s and I can't hit 630kh until I am at 1075/1600 on my clocks. Same voltage and I am getting 1kw/rig now, I had them at 1.1v and was pulling 1150w, so thanks for that lol
i have saphire vaporx dual bios oc edition cards i use reaper to mine if you would like to know the setting i use pm me
i have found with the cards im using mem clock makes very little difrents but uses loads more power ( i mine scrypt )

It really depends on system, motherboard and card. I mine at 67C all the way up to 88C per card.
AMD says these cards are meant to handle up to 125C.
I've seen them run as hot as 96C before shutdown. Absolute Max I'd run a card is up to 91C...even then i'd use caution.

I have 2 MSI TwinFrozr's undervolted - they manage to run steady at 66 deg's
67° at 26°(ambient temperature)
fan 53%
fan 53%
Mine has a target temp of 80, but t normally run just below.
Waiting for cables to move my machine into the basement.

For me, a 5mhz increase comes at a sweet spot where it comes with a 5°C increase. Go from 1000 to 1005 on the 7970 and it jumps from 83 to 88. Not good.
However, AMD says these things run stable at 90-92 as maximum temperature target. They are supposed to take peaks of 105. So 85-88 should theoretically not damage them

mining ltc is not summer frendly, 79-83C
This. I moved back to BTC for the summer - 21C outside, all windows open in house, computer room was sitting at 34C overnight when mining LTC!
Stays below 28C doing BTC, and saves 200W at the wall.

Sapphire HD6970 @ 75C
Asus HD7850 @ 74C
Gigashyte HD7950 @ 69C
All cards in a well ventilated Define XL R2.
Just pulled the HD5870 which ran at 92C with fan at 100%. Saved 150W at the wall too. Fan is OK and heat sink is clean. TIM replaced recently. I think it's just f**ked.

good to know
My Sapphire 7950 3L's run about 71-75C at 1125 voltage
My MSI Twin Frozr 7950s run at 68-71C at 1085 voltage

2x7950 in a computer case tend to run around 70-74C and get 590kH/s on 989 Core Clock and 1479 Mem Clock, but I undervolted to 979mV. Undervolting is magical, without undervolting one of the cards hit 96C, which was way too high for my liking...
Mine are voltage locked so I'm up shit creek in a manner of speaking. In saying that, I CBF reflashing to a different bios and seeing as having one card in at a time doesn't go past 70C, I'm keeping fingers crossed that these risers will help me out somewhat in spacing the cards out more and allowing more air to flow around them. Had a constant temp of 65C last night given it was a rather cold evening and the lowest I got was 59C...
These are the Ghz editions non reference I might add.
Edit: Argh didn't read you stated 7950, thought it was 7970 - My bad

2x7970's in an open case 4x120mm fans blowing straight on them and card fans @ 85%. When sandwiched together, whichever card I have in the top slot rockets to 100C easily and would keep on rising if I didn't stop cgminer. The bottom card in this configuration only gets to about 75C. On their own they comfortably sit between 60-65C, so I'm waiting on powered risers to arrive so I can hash with both the cards again instead of just the one. This should hopefully solve my cooling issue or at least stop the insanely high temps.
Mostly 95C but a couple of 7950s run at 100C. Not good I guess and the weather is only getting hotter!
I would not be surprised if those burn out before you make ROI.
73-74°C at 100% fan speed. Is this risky?
The lifespan of your fans drop dramatically running full tilt like that. I keep my cards around 75%, temp is ~78C. During winter months I get sub 70 C...
