A beast of a miner with whisper-quiet hydro-cooling. Setup took 25 minutes. Temps stay below 40°C, and it’s performing exactly at 473 Th/s. Profitability is strong, and ROI is pacing ahead of schedule. You should order only through this website antminers23hyd.com—smooth and safe experience.

Nice antminer and i like customer services

I’ve seen plenty of miners come and go, but the Bitmain S21 XP Hyd 3U is hands-down the most impressive we’ve added to our Canadian facility. The hydro-cooling is next-level. With temperatures in Calgary fluctuating, we needed consistency, and this unit delivered. The cooling loop setup was intuitive, only needed minor adjustments. I had it hashing within 30 minutes.
I’ve been tracking the metrics daily, and it’s locked at 473 Th/s without fail. It runs cold and dead quiet—even when the rest of the server room is roaring. Temperatures average around 36°C, with next to no thermal spikes. That level of thermal stability equals longevity and better uptime.
In terms of ROI, we’re trending toward a 3-month recovery—impressive considering our hydroelectric pricing. This is one of the few miners that I can say truly pays for itself fast.

Don’t overthink it. Just buy it.

Absolutely the most reliable BTC miner I’ve ever owned.

As the CTO of CryptoForge Europe, based in Prague, I’ve handled my fair share of ASIC units over the years—but the Bitmain Antminer S21 XP Hyd 3U (473Th/s) genuinely stands out in both performance and engineering finesse. We recently added two units to our mid-size hydro-cooled rack system. Setup was remarkably straightforward. I appreciate that Bitmain’s design keeps compatibility in mind; the water inlet/outlet fittings matched right up with our existing closed-loop cooling system, and we were fully operational in just under 35 minutes per unit—no fuss, no leaks.

I’ve worked with several miners over the past decade, but nothing has performed like the Antminer S21 XP Hyd 3U. We set it up in our crypto facility in Southern California. The setup took under 30 minutes thanks to the clear routing of the hydro connections and intuitive interface.
What really impressed me was the silence—this thing barely hums. You wouldn’t even know it’s pulling nearly 500 Th/s. The temperatures have held steady around 37–39°C even during continuous operation. The hash rate has been stable and consistent since day one, with no noticeable downtime.
Profit-wise, it’s performing above expectations. Our projections estimated a 4-month ROI, but we’re on track to recoup in just over 3 months—even with California’s high energy prices.
