70-80 Celsius mark is fine, but mostly 70-90 if clocked and runing a miner 24/7 with extra flags

Sometimes it's under 70, sometimes it's over 70, depending on the ambient. When it hits 50F at night, they stay pretty chilly. When it hits 85F in the day, the fan is crankin and they get underclocked to stay below 73C. The joys of living in New England.

Mine stay pretty cool at 80c considering ambient is usually in the 90s

Living in Atlanta. In the daytime my xfire 7970s are averaging 78-82 C during the hottest part of the day. Been around 85F, 30C ambient temperature in the room where the machines are running. Temps outside also the same though very humid out there.

60-75 average ranges depending on temp outside as Im drawing in cold air. Although one sunny hot afternoon my GF decided to close the door to the room my rig resides in cutting off the air circulation I had going on. When I noticed it was closed a few hours later I walked into what felt like a pre-heated oven and the temps of some of my cards were low 90s and one of my systems had already crashed. YIKES!

Pansies. Some of my multicard rigs idle at 57C on the hot card, so keeping under 90C is good....considering the ambient in the room was 103F. That was with full AC running in a commercial building - outside ambient was 106F last week here in SoCal. These damn voltage locked cards will the first to go

I'm doing my best to keep them under 75C.

I've ran mine at ~70 for months. The VRM temps are what most people should be worried about more than the actual cores. The VRMS almost always run hotter than the cores and they sometimes have bad cooling with the aftermarket designs. Use GPUZ to see what they're running. I'm OK up to 85C, beyond that is asking for trouble even in the short term.

Heh 6990 on stock clocks runs upto 99 with other cards next to it Underclocked & undervolted it and gained a few mh/s once the temps dropped to 70-80 degrees. cool hey

Totally agree with that!, VRM temperatures are the most dangerous ones. Typically in 7950 / 7970 Sapphire Dual X Cards, they are 1 or 2 degrees above core temperature, so it is not dangerous, but this is on BTC mining. In LTC is completely different, I have some cards than in LTC are 10 degrees above, others 15 degrees above core, that's why when I mine LTC y downclock the cards to 820 - 840 Mhz, and lower the voltage to 1.080, because VRM gets hot as hell in LTC! at stock speeds I have seen 86 degrees on the VRM YIKES!! (which they are also cooking the memory chips!). I think that sapphire completely underestimated VRM cooling with the flat heatink that covers the VRMs and memory chips.

My two Gigabite 7970 run 65-87 C. One runs hotter than the other one.
The one that runs cool is consistently 72 C at stock speed. The hot one runs consistently 80C at stock speed. I swapped the two cards to different PCIe slots and get the same result.
So I removed the hot 7970 yesterday and checked it carefully. Long and behold, the screws for the VRM heatsink were loose. What the h*ll? It's a new one month old card. So I tightened the thing down to finger tight. (Not very scientific, I know.)
Then decided to remove the heatsink and see what's going on underneath. There doesn't seem to be enough thermal paste between the 7970 core and the heatsink. Removed the existing thermal paste, cleaned off with rubbing alcohol, reapplied with Arctic silver paste. Now it runs consistently 4 degree C cooler.

after reading your post, paranoia hit me again I will check all the screws of my hottest cards just in case.

You are using scrypt right? (LTC) in scrypt there is usually 10 to 15 C higher in VRM than core temps, so you must get this value down at least 10 degrees, increase fan speed, relocate board to a cooler area or lower engine Mhz. (860 maybe) I think that max temp for vrm are 100C (somebody correct me if I am wrong), but even if you are not, at these temps you are cooking the ram chips too!, which usually share the heatsink with the VRMs.
