two 7850's bottom card 61 top card 68

stock fan settings.  side of case removed and stand alone room fan kind of blowing into the open case.

1250mhz over clock on bottom ram at 600 mhz stable 350Mhash

1100mhz oc on top card ram at 1200 mhz just barely stable 305Mhash   This card has my monitor on it and video is constantly crapping out with display blocks and stuff just messed up. Kind of like someone is playing an old atari asteroids game in the background. 

both sapphire dual fan 2gb cards

Also a 5770 that ran around 85. OC to about 940Mhz. 225 mhash. fan at 100%. WRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR. Ran for six months straight like this stable no problems. Pulled the plastic cover and removed the hairball jamming the heatsink and redid the thermal paste and back to 70 deg. Just saying that a little maintenance can go a long way to cooler temperatures.  This has a single turbine style fan and is LOUD.

Using a combination of Trixx for the sapphire cards and AB for the 5770.  I like how AB put a little temp widget in my taskbar.

That's all

Does anyone know why mining LTC GPU temps are much higher than mining BTC?

For instance my temps stay 80'ish Celcius when mining BTC.  When mining LTC my temps rise about 5C higher.
5 C Higher in the GPU, the VRMs are easy 10 to 15C above the GPU temperature, be very careful in LTC mining, specially if you OC the cards.

That is because LTC uses A LOT the memory and the internal bandwidth between memory and GPU engine, while BTC only uses the GPU, not memory.
also you will have 20 to 30% more power consumption in LTC than in BTC depending on settings.

SM411: check your VRM temperature, it's 85C, a little high, try to keep that one not more than 80C for safety, it is easier to replace the fan than blow the VRM and have to send the entire card to RMA Cheesy so, if I have to choose between FAN life and CARD life, I will choose CARD life Smiley, you can even remove the plastic cover, both fans and buy 2 artctic cooling F8 CO fans and screw them to the heatsink directly Cheesy

check the 80mm 4wire PWM fan: http://www.arctic.ac/en/p/cooling/case-fans/556/arctic-f-pwm-co-.html

I ordered a couple of them because one of my older cards have fan problems, I already fixed them but it's a short term solution, will have to replace them soon, two of these will do Cheesy

Im mining bitcoins. I lowered the temp to 85 by increasing fan speed. Can increase more, but fan is then running >80% and I guess that will ruin the fan over time.

What is the maximum GPU#2 temp i can run?
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.

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

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.

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.

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.

Heh 6990 on stock clocks runs upto 99 with other cards next to it Sad

Underclocked & undervolted it and gained a few mh/s once the temps dropped to 70-80 degrees. cool hey Smiley

Rig1:  3x 7950: coolest card 58C hottest 66C

Rig2:  4x 7850: coolest card 55C hottest 63C

Rig3:  2x 7970: coolest card 60C hottest 67C

Auto fan, Auto GPU clock (cgminer 311a (kano's mod), xubuntu 12.04 from persistent usb flashdrive)

Ambient temperature 25C, window open  Grin

I won't sleep if any of my rigs touch 70C, no way Smiley GPU's are way too expensive to risk them like that IMHO.
70 and up to 80C is not dangerous for the GPU.
I've ran mine at ~70 for months.

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  Angry

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!
