Bitmain's at it again with their new Antminer U3S21EXPH. 860 TH/s and 13 J/TH efficiency is wild! This is gonna shake up the mining scene for sure.

Sounds impressive, but can it really function without hydro cooling? Fans alone seem weak for a unit that needs 11,180 watts. How’s that gonna work?

Found another claim saying it's water cooled too. Just saying, this isn't listed on Bitmain's site, so it makes me skeptical. If it’s real, I'd be shocked.

Not convinced it’s fake those specs are pretty close to what's been rolling out recently. Maybe they adapted some cooling tech we don’t even know about yet.

Seems like a repackage of old tech. I mean, a CPU bump to control more hashboards? Could be just marketing fluff to hype it up. Nothing groundbreaking here.

Heard these ASICs might drop next year. Got links that show they're already getting attention in the community. Let's see if Bitmain delivers.
