Note that some cards throttle at lower temperatures. I remember my 7970's artifacting when they got over 78°C in BF3.
Alright, this is what I had thought, but the last time I had looked at building a mining rig was a few years back, so I thought perhaps the technology had changed.
He said his fan speeds are 45-50%, and one of his GPUs is water cooled. But like a real pro, when he says water cooled, he really means water, not the coolant liquids that you are supposed to use.

But what Cannot be measured is the temperature of the fackin capacitors on your GPU, Capcitors a generally rated for continus use at (im not sure, Someone poke me on this part) 60°c?
Altough there maybe some tech unknown to me about monitoring temps on cards that came with pci-e 3, So dont bite at me

No, but my 5870 has 9 different temp sensors on it. I just checked with GPU-Z. Gives you a pretty good overall picture. Right now, my core may only be 68, but my VDDC is 76.
103C?!?!? Holy crap.
I keep mine at 70C and a variable fan speed not to exceed 80%, after that they start to downclock themselves.

That's almost exactly what I use for settings. 75-80% fan speed, depending on the card.
Gpu temps can be weird. I would consider 80+ to be hot, and 90+ to be dangerous. Now 3 things you need to consider with temps that high:
1) As weird as it sounds, if you're gonna run cards that hot, it's better to do it 24/7, than, say, 20 hours a day. Getting them hot and staying there is better than hot -> cold -> hot -> cold -> etc.
2) Usually VDDC temps are going to be higher than Core Temps. You do NOT want to burn out your voltage regulators. That WILL be what kills your card running that hot 24/7.
3) With temps that high, you still wanna make sure you don't run your fans too fast. That sounds weird, but there is very little to be gained from pushing your fans from 80% to 100%, esp if you have limited airflow already. All you're doing is wearing your fans down faster. 3 months @ 100%? They're due to die anytime now.

So anyway, I'm in the process of setting up my first mining rig, after finally finding a place to put one. And I was talking to a friend about what he was running, and he has a few cards, 2 6950s, some 6870s, a few 5770s etc, and I was asking him about his rig before I set mine up, and I was quite alarmed when he told me his have been running at 103C for the last 3 months 24/7. How does that even happen? Don't GPUs die at 80C or so?
Just wondering mostly because this kind of thing majorly effects how I set up.

These temperatures are perfectly normal. There are safeguards within a GPU to prevent it from getting to dangerous levels (i.e. it will throttle back to a smaller speed automatically until temperatures are acceptable). Mind, 103C at 24/7 is probably on the high end, but nothing that high end/dual GPU cards won't be subjected to under heavy 3d environments such as cutting edge gaming at super high resolutions
Yes these safeguards most definitly exsist, Sometimes they work so great you never notice them, Other times they work so great that your GPU just resets on you with a warning (love that feature, honestly)

Woah!!!!
WOAH WOAH WOAH.
Your buddy IS going to blow his video cards if the gpu's are above 100°C He must have some swag gear if it hasnt blownout after running like that for 3 months.
90° Is a fine "max" Personally i feel that 95° is when a gpu starts to take damage, But that all depends on the cards themselves.
Just because your buddy's ARE and CAN run that hot, Does NOT mean anyones can, Or that you should even get NEAR there.
Fucking HELL he is Seriously going to blowout his hardware, Odds are that his fans are at 100%, GPU/CPU Fans are NOT meant to run at 100% and you will break them if you constantly run them that fast, I found out the hardway. Trust me. Case fans etc, Goahead, Crank those up.
To reduce temperatures, Drop your memory clock, You'll get HIGHER hash rates (by upto 20mh/s a card, And no im not fucking with you) and colder temperatures.
I Heavily reccommend a $20 20x20'' BOX FAN air circulator, Remove your side panel, And slap that thing on at full speed,
Brought my 6990's 104°C fans speed 100% Way down to 81°C and 71% fan speed.
DO NOT RUN YOUR GPUS THAT HOT, JUST BECAUSE HE CAN, DOESNT MEAN that you or ANYONE else can, or should do that
I wouldn't call them perfectly normal, but I recall Graet of Ozcoin trying to kill a card that had a dead fan by mining on it, but I don't remember how long it took to die.
I would aim for 60 to 80 degrees, more than that will accelerate the time it takes for them to die.
