Never had any heat problems with my Gigabyte HD 6970(6950), it has a Gelid icy vision rev2 and never reached 60 degrees Celsius, my Saphire HD7970 died because one fan failed and my XFX RX580 needed to be undervolted and an aggressive fan curve to stay under 65 degrees Celsius, wile I have an 5870 vapor X than only needed a lite more fan rpm to stay under 65 degrees, and it is very silent. The r7 260x I have is from ASUS and with its default cooler it overheated easily, reaching more than 70 frequently, so I recycled the cooler from a 7770, and now it never reaches more than 57 degrees even with furmark or kombustor.
Neither AMD nor Nvidia make hot GPUs, the makers of the cards are the ones that don't implement proper cooling on the cards.
An HD7970 is very expensive taking in account that they already have ten years, for me is dangerous to buy any HD7970 for the prices people ask, even an HD 7770, I've reflowed the one I had two times, you can end with a reflowed card, and we know what that means, they should be around 40€ max nowadays but the market.... and the people ........
I mean, buying a graphics old graphics card with, nobody knows how many gaming hours and in what circumstances for a lot of money is very risky from my point of view.
I think it's better to buy mining cards because a good miner tries to keep them cool and clean and power controlled so that the mining is more profitable, even knowing they may have been running 24/7 for years.
AMD and nVidia do make hot GPUs, 3090 is one recent example the 3870x2, 4870x2, 5790, 6990, 7990, GTX480, GTX580, GTX285, GTX 295, 8800 Ultra being others ..or the entire Fermi series if you want an entire generation of space heaters, the reference models from nVidia were particularly bad. Most of the examples listed are reference models using nVidia/AMD designed cooling, AMD has a lot more in their HD2000/HD3000 cards which used a terrible blower design.
AIBs can only do so much to dump heat and I have seen some really ridiculous examples of AIBs having to go the extra mile with their cooling, really the core issue lies directly with the Fabs and how they design their GPUs. In the case of Fermi nVidia never solved it even with two generations of GPUs based on it (GTX400 and GTX500), with the 3090 its simply down to the GDDR6x ICs being utter power hogs and running crazy hot for Vram.
So yes the Fabs do indeed design and build hot GPUs, its not 100% on the AIBs.
As for buying mining GPUs . .sure so long as you can trust the seller and they are transparent with how they handled their GPUs.
Oh noes, the cap let the shmooo out 😁
