I heard about some problems on RTX 3090 GPUs at gamer forums.
There is no so many information about ETH mining. I found a youtube video abut Zotac RTX 3090 mining. 310 mh at 910w.
Sure, it is possible to get 120 mh per gpu but The fan of Zotac Trinity GPUs RTX 3080 and RTX 3090 makes so much sound.
How about other models ? is there any hardware problem as the gamers reports some hardware problem abot RTX 3090?
the zotac can get to 120+ but you will need run the fans at max and put a fan on the back. The fan blades on the zotac trinity (3080 and 3090) are not fully enclosed, so a lot of air is blown around the fan, rather than down and into the heatsink. There is also a "lip" that covers the bottom part of the heatsink, so hot air can't escape properly (like the msi evoke/xfx thicc2).
