I voted under 75 cause my 680m and 7970m never go above this after gaming for long periods.
In contrast my 6990m which was at manufactured @40nm fab process was way too hot and would constantly hit 90c.
As we all know heat destroys semiconductors and TBH I like the idea that the cooler it runs the longer it lasts.
YMMV but no complaints from my Alienware or Clevo cooling methods, they both essentially work. If you need to blame someone point the finger at the manufacturer who is pushing the core beyond its limits.
Good luck.

Cooler may be better but it doesn't necessarily equate to longer life by any appreciable amount. Running at 75C or 85C if there isn't a flaw in the manufacturing or design they should last a long time unless you push it 24/7 at those temps.

Hmm, well, is there fire coming out the rear of the machine?
If not, yeah, that's either a software or sensor issue. -
Yeah it's a software error. I've had comical ones like that where HWiNFO64 told me my CPU ran at 110 GHz and consumed 100W.

Got mine down!
Auto fans, 79C master, 81C slave on first step up (it never hits 87C so it doesn't spin to the next level)
Max fans, 70C master, 72C slave.
How?
880M runs 849MHz @ .893v (probably would be stable at .887v as well but .893 is definitely stable and the default voltage at that clock of .875v crashed after a few minutes so I figured it wouldn't hurt to give it a decent bump). I only ever really wanted 780M stock performance and decent temps. Now I have it.
I'm glad I logged the voltage tables when the card was going through its various states. That's the one thing that's nice about rebrands - they're binned much higher.
Having the option of gaming near silently now is a huge plus too.
EVGA Precision X is set to apply my settings on boot so now I'm set. Perfect balance of temps and performance. If I need more, I can always raise it back up (I discovered that 954MHz @ .981v yields 80-82C with auto fans so no more heat throttle either) but this is just great! -
That's one thing I've never actually tried - undervolting while overclocking. Maybe I can get some temp reduction that way.

This is actually an underclock for me. Stock 880M = 954MHz but the drop in performance from the stock vbios to this underclock and undervolt is only about 5% because of how poor the stock vbios is. It makes much more sense to sacrifice 5% to gain 10C temp drop and over 20C from full 993MHz boost (it takes around 2 hours but 993MHz will core throttle because it hits 94C).
The 780M isn't binned as high as the 880M - it runs 849MHz @ 1v stock I believe. Its worth a try though. The only reason I knew this would work is because I watched the stock voltage at each core speed and wrote the values down.
880 goes: master/slave
993MHz - 1.012/1.018v
980MHz - 1.006/1.006v
967MHz - .993/.993v
954MHz - .981/.987v
928MHz - .968/.968v
836MHz - .875/.875v (but this will crash on my cards so I bumped it to .893v and pushed the core to 849MHz and its totally stable) -
Preliminary results using Unigine Valley show that 950/3000 @0.950V instantly crashes (not really surprised!). However, 950/3000 @0.975V seems perfectly stable for the 10 minutes I ran the benchmark for. Temps dropped to 90C with the undervolt, down from 93C at stock voltage.
Now I'll see how far it can go at stock clocks...
edit: @ stock clocks it'll get down to 0.912V, stable. Went from 79C stock voltage to 77C undervolted.Ethrem likes this. -
Nice man! These 880Ms don't even have much wiggle room @ 954MHz! You got nice card there.
Glad I inspired you to do some testing too

What temperatures are your ideal temps for your GPU(s)?
