Yeah, I have done that 3 times myself with success every time 
erm… thats about as stupid as it gets. there are a lot of dangerous parts on a graphics card. doesnt matter if the oven isnt hot enough. any time you use the device in a way it wasnt intended the risk becomes very severe, expecially without a heat sink. i do not advise this, especially not if yo u have a high end graphics card as there are more dangerous parts (resistors, compositors, transistors etc…). i know this is an option so people in a bad economy dont have to spend more money, but if your graphics card is that F’d up, what you need to do is remove the heat sink, clean it, remove dust, let it cool, PROPERLY replace thermal compound with aftermarket thermal compound (noctua is my favorite), replace the heat sink, install card. If it still does not work it is time for a new card, not to risk a small fire.
If it is not working it is not working. dusting it off will not fix it. Its more dangerous driving to work. put it on a cookie sheet and under a cake pan. open windows.
Thing about electronics is that unlike some mechanical parts, there is no oil leak indicating a likely cause.
I think you should inform yourself before calling something stupid.
Most hardware is produced exactly in that way, it’s de facto industry standard - or did you think someone, or a machine solders all the parts individually? 
Reflow soldering is the term you want to look up…
And if you’re not skilled enough to do it in your stove, there are plenty of companies that offer your hardware a spin in a reflow oven…
Cleaning a gfx card and replacing the thermal paste dosnt repair a card with a bad solder, i trip to the oven does. And it’s not dangerous at all, at least not more dangerous than putting bread into the oven, that can catch fire too if you let it.
I’ve fixed a GTX260, GTX460 and a GTX480 (The GTX480 is in my computer now) using this method, and I’m glad I did that instead of running out and spending loads of money on new graphic cards. And if that makes me a person with bad economy in your head, thats fine by me. I just think it’s stupid not to use the knowledge you have to fix the card in a fast and secure way, instead of just running out and buying a new one. And what do you have to lose? The card isnt working before going into the oven, it’s not like you can break it twice 
Doing this once is probably not too dangerous, but I wouldn’t necessarily want to do it in the same oven that I use for cooking food. Many electronic components probably contain stuff that is not too healthy, and the solder itself may contain heavy metals that aren’t too healthy, and will start to evaporate when you heat them.
If you do it with chicken, put the chicken below. To avoid the drops falling on the GPU.
LOL
Just cuz it worked doesnt mean you should do it. Thats like saying that smoking wont kill you just cuz it cures your shakes.
You might not break IT twice, but you might break your house, you know, when its on fire.
if you really want THAT graphics card than do it outside in a toaster oven away from other people!
I still think there is no point though. if its jank enough that you would risk your house, than whats a couple hundred bucks?
I agree about the metals.
my point isnt quite as much that following directions is dangerous (though it is, and it also damages your graphics cards GPU), but its not exactly like there is a single set of instructions. there are a lot of people telling you how to do it, some people, and most of them dont know jack about how a graphics card operates and why this is dangerous.
Like you said, once probably not too bad, but its still just straight up stupid regardless of whether it works or not.
Risk the house? What are you talking about? That all of a sudden the card erupts in a blazing fire or what? I really have the feeling that you dont know very much about these materials and how to handle them? There is NO risk of fire when following those instructions, no more than following a recipe for baking a bread.
to say there is NO risk is again, about as stupid as it gets. I have a feeling that you dont know much about computers, not just the materials if you would shrug off all risk.
what i know is that there are hazardous parts on a graphics card, and i HAVE watched them blow, and even catch on fire. if you really want to do this, do it right, with a soldering iron!
I never said that EVERYONE here who tried this was gonna burn down their house, but i am saying it is a good way to do it. the same way if we all smoked we all wouldn’t get cancer, but smoking is a good way to cause it. is smoke bad? no! do things cooked over an open flame taste Fing awesome, hell yes, but our bodies where not meant to handle smoke. same with graphics cards (take this as an analogy cuz that question mark at the end of your exclamation telling me i dont know about the materials has me wondering if i need to elaborate.)
REGARDLESS OF WHETHER THIS IS DANGEROUS OR HAZERDOUS OR NOT!!! the max temp on an ATi is 80c before you start doing damage to the GPU its self and you are talking about taking it to 130c… this is straight up stupid either way. Man up and go get a real graphics card instead of wasting your time being cheap and lazy trying to do something that isnt advisable in the first place.
ERM… reflow is done on a plate, and in industrial loads a conveyer belt with directional heat in hundred thousand dollar ovens DESIGNED for this… unlike the ones in your house.
That’s just complete nonsense, the solder on GPU is meant to be connected in a reflow process such as you get with a reflow oven, not a soldering iron.
the max temp on an ATi is 80c before you start doing damage to the GPU its self and you are talking about taking it to 130c
The maximum operating temperature of modern GPUs is over 100°C, but you probably won’t reach that temperature at the core if you put it into an oven at 130°C.
i know its complete nonsence, the point is that there is no point…
the “safe” operating temperature of an ati 6970 (and i know cuz i OC the hell out of mine) is 70c, maximum is 80c, after that it void warenty, 90c is where i have personally had crashes and video lag, im certain if i had actually let my card get to 100c it would be toast. graphics cards where NOT meant to handle temps that high.
I’m sorry, but you just keep showing that you have no idea what you are talking about, and I’m just gonna leave it at that. But really, you should look into how stuff works before making claims like the ones you are making here.
Good day to you
alright fine, im out on this one. i have a $3000 dollar computer and a $200,000 dollar home. I draw the line at baking my hockey skates. If i really needed to do this i would go out and get a legitimate reflow plate for it and do in my work garage, where im not concerned if something does go wrong, you know, except for the 400 dollar graphics card gone to shit. ive been building computers for years, and there is ALWAYS a risk in doing things makeshift. an oven is not a reflow plate and shouldnt be treated like one. like i said, im out.
I failed to find any official information by AMD (or any of its OEMs), so this is from NVIDIA:
“NVIDIA GPUs are designed to operate reliably up to their maximum specified operating temperature. This maximum temperature varies by GPU, but is generally in the 105C range (refer to the nvidia.com product page for individual GPU specifications). If a GPU hits the maximum temperature, the driver will throttle down performance to attempt to bring temperature back underneath the maximum specification.”
I highly doubt going over only 80° will void your warranty, the drivers have builtin throttling and forced 100% fan, which doesn’t kick in until 95° on my AMD 5850 GPU. It runs rock-solid around 90°, maybe you have a bad model (or damaged it through OC). EDIT: Also, 90°C in an overclocked state is not the same as 90° in normal state. Try running it at stock speed but with low fan settings, it’s probably going to be stable.
High temperatures themselves are not a big problem to the chip, temperature fluctuations causing metals to expand/contract is what causes cracked solder.

this sums up my experience as an extreem overclocker. 100c for a couple seconds wont hurt it, but for any longer than that and my computer just straight up starts acting up then crashes. ive pushed my card to the limmits multiple times, and i can tell i did some perminant dammage in the process, and you are talking about leaving it in the oven for a prolonged period of time. ill drop all my other arguments, but if i was so attached to this graphics card, i would go out and buy a legitimate reflow iron.
