Most 3090's used for ethereum mining used reduced power load and temperatures. https://www.reddit.com/r/EtherMining/comments/q2v061/comment/hfnslen/?utm_source=reddit&utm_medium=web2x&context=3 https://www.reddit.com/r/EtherMining/comments/q2v061/comment...
e.g. this guy:

Some individual enthusiasts were trying to get every last "megahash" for benchmarking bragging rights, but anyone who had a bunch of 3090's would minimize power consumption because the marginal profit on the last 50+ watts was negative, which had the nice side effect of lowering temperatures.
- code_biologist 4y ago+1. I mined on a few 3060s (and heated my house) last winter. All with cores underclocked, memory overclocked, all at ~60C temperature wise, each consuming about 120W.
- tgtweak 4y ago3090 on ethereum (even after undervolting/underclocking gpu and bumping vram frequency) was hitting 100+C on VRAM. You went from 95MH/s to 120MH/s by doing this. Throttling happened at 110C so you wouldn't notice it on hashrate unless you had really poor cooling. It was causing premature failure on vram even in the first months of use at these temperatures. If you put some extra heat syncs on the card and got vmem down to ~90C you had no issues. Almost all miners were doing this. If you didn't cut back the gpu voltage/clock it would increase vram temps to 100+ even at stock vmem frequency. GPU core temps dropped by 25-30C when underclocking/undervolting and power would also go down by 60-80W.
