I have the DUAL variant, and it's tiny, I agree the undervolting is madness, out of the box my stock game clock was something crazy like 350mhz higher than the ref nvidia card, how about yours?
I just choose to undervolt it about 50-80mhz game clock higher than ref clocks, my fan never comes on apart from
once doing RT in Control at 1440p ultra. I dunno about your TUF, but my Dual's fan comes on at 65C, to which my temps other than that once, never turns on, due to it spending it's life at 53-57C on average, when it was really hot outdoors it went to 63C, but that for after 8 hours flat, my rigs fans barely turn on and it lives 2 feet from an airing cupboard, so I think these cards aren't bad 'for what they are'?
Power draw wise, I use between 105-115w at 1440p native max settings, CP/Control I use say 135-145w peak 1440p DLSS/FG/RT on, what kinda results did you achieve?
Can confirm as of tonight, Cyberpunk 2.0 runs very smoothly, I wouldn't say noticably any different from 1.68 patch (think that's the number?) but that isn't a bad thing, both ran nicely
