Speaking of 4070 Supers, here's a PSA for undervolting...
I visited a friend for the Super Bowl who had recently upgraded to 1440p gaming on a 4070 Super. His home office is a 15x15 room, 8ft ceiling, and he has to keep the door closed. So he hadn't anticipated how severely a gaming system would heat up the room. The temp would jump as much as 7 degrees after an hour or two of gaming.
At load in two modern titles, his CPU would peak and hover around 70C and the GPU at about 62C. Hold your hand over his exhaust fans and, yeah, he essentially had a space heater in his office.
While I knew undervolting would help, I didn't oversell it because I wasn't positive that the difference in heat generation would be huge.
I went with safe, easy undervolts for both that I knew wouldn't cause crashes. For the CPU, I bumped his 5700x down from 1.1 to 1.025, and upped the frequency from 3.4GHz to 4.0GHz to compensate a bit. And for the GPU, I flattened the curve at 900mV/2600MHz, and added 1200MHz to his memory clock for a little balance.
In the two games we tested, his CPU temp dropped from 70C to 43C, and his GPU from 62 to 46. So not only was the heat generation under control, but fan noise was way less, too. In the month since, he says the heat issue in the room is gone; that it might jump a couple degrees if he games for a long time, but not enough that he feels it.
I used NovaBench and ran an identical encoding job before and after the changes. While the benchmark reported an overall performance drop nearing 10%, his FPS in the games we tested were only down by 4%. His encoding performance (CPU only, no NVENC) slightly improved.
Undervolt your stuff, boys and girls. Worth it.
