How hot would your gaming GPU have to be for ANY damage to happen?

Or would your PC turn off to prevent even the smallest bit of damage?
This is a complex question. First, imagine your computer as a muscle. Imagine the GPU being the connective tissue, and the heat it produces are calories. When the muscle flexes, stress is put on the connective tissue and it produces calories as a result of energy expenditure. If you flex these muscles a lot, you will intimidate other men but women will just see you're flexing and think you're a homo. In addition, you will have to do some reps to turn the calories into gains if you want to bulk up for penis inspection day.
But really, I don't fucking know. I'd say like ~50*C but I'm running a Voodoo3 and those things are indestructible.
I've checked and mine's been over 50*C when playing GTA V.

That's nothing for a GPU, I'd be worried if it started going into the 80s, but 50 is completely fine, most of my games run at ~ 75C, and Nvidia rates my card as safe up to 98C
Now a CPU, you generally shouldn't let it go above 60-65C
CPU tmax is ~85C. That's when it shuts itself off to protect it.
GPU-s take more, I have gamed on ~120C but that's not healthy. I would keep it around ~80C max but depends on the GPU, 90C is okay too.
I had a 590 that ran at 90C+ for several years. My friend had no clue how to clean it so when I got it for free it shot up to 99C when I put it in and played a game, cleaned and after it ran at 85-90 degrees and I had it for 6 months like that. At this point it had been abused at 90+ degrees for years.

Really depends on the card. Some don't like going significantly over 70° for an extended period of time, and a card that would be stable at high temperatures at stock clocks might not be so stable when overclocked, even at those same temps.
Both my A10-6800K and HD 7950 run between 60-75c when playing. This really, really makes my room heat up though. Even with my door and window opened the room remains hot.
So glad I'm British, we barely get any heat.
I'm pretty sure all of them have a failsafe for that.
Just get a good cooling system and you won't ever have to worry about temperatures. I'm running dual monitors on one 980 with a STRIX waterblock, idling at 40 degrees and never goes above 65.
My cooling system is good, I was just wondering if it was safe to play GTA V when it makes my hardware go around 60*C.

Humidity motherfucker, can you cope with it?
On a normal day of playing games my GTX 460 will happily run at 50-60C, but this is due to MSI sticking a shit huge heatsink and fan on it. On a humid day, the heat can't dissipate too great, so 80C is common. My old Radeon HD 4670 spiked to 112C when my brother was playing on my PC once and it did no noticeable lasting damage. GPUs are designed to take a lot of heat, they are many-core after all, heat is something that is going to happen.

My 760 goes up to 60c and its just fine. Like others have said, you dont need to worry until it hits 80-90. You could also downlaod speccy and it will give you a readout on your temps.

tmax on any recent Intel GPU is 100C.

You might be thinking of tcase
[QUOTE=Satane;48216771]Does humidity really affect pc cooling?[/QUOTE]
It can if there's a lot of it, though it's probably never that much of an effect
My GTX 770 will hit 70 degrees if I'm really hammering it, and at this point the fans are screaming like banshees so I assume it doesn't want to go beyond that.

I believe newer CPUs are able to run a lot hotter. The fans on mine don't even start kicking in until it hits about 90.
OP mentioned physical damage so here it is
With electronic components and temperature, you have 2 points of failure. There are naturally other things high temperatures do but after the second the board is damaged anyway.
First you have board warping from heat expansion. This is from heating and cooling over and over and over. As the board heats up it expands slightly, as it cools it contracts. This puts repeated strain on the welds holding components to the board, which can crack and stop conducting. The best you can do about this is to minimise big temperature swings - going 30C up and down is much less harmful than 60C.
Most Games Console failures are due to this one.
Second, we come to the first component that'll fail to temperature, which are the Capacitors. In simple terms, they are made up of an electrolytic fluid, which dries up over time - accelerated by temperature. On top of that, most are rated to function only up to 105C. Across all electronics, the first components to fail are usually the capacitors. This is your thermal max - you should never be running electronics up to this temperature.
The insides of ICs, other components, and the board itself are all made out of materials that can withstand at least double the temperature a capacitor can. However, as temperature goes up, electrical resistance rises too, which is why your devices will start to malfunction. The tolerance to this depends on the component, but all manufacturers are going to expect you keep your equipment running below that 105C capacitor upper limit anyway and as such won't bother making their device redundant beyond that.
To be fair quality computer components no longer use electrolytic caps, especially in motherboards. Almost any mid-high end motherboard is going to have solid type caps.
They can take a lot more than 50 that's for sure.
And depending on the card and the environment of your home, it's gonna eventually gather dust inside it, gradually increasing idle temps, and I suppose thermal paste dries up over time too.

I think I have one of those lying around in a box somewhere, I bet it will still work

Got some STRIX 970 here I think, about 40c at idle as well with 0 RPM fan. :v: Not water cooled tho, and justa single monitor.

No, you should be very alerted in your position, and probably panic.
