Antminer S21 IMM - Bitcoin “Submarine” that Hits 301 TH/s

We unbox the Antminer S21 IMM , a true immersion-cooled Bitcoin “submarine” that takes mining to a completely different level 🛢️⚡ Fully submerged in dielectric fluid, this machine runs without fans, without noise — just pure, uncompromising hashing power.

In this video, Lucas breaks it all down — from design and specifications to why immersion cooling is becoming a game-changer for serious miners. And most importantly, why this isn’t something you can simply plug in and run at home.

💥 Here’s what makes the S21 IMM stand out:

239 TH/s at 3,824W (16 J/TH) in standard mode ⚡
Up to 301 TH/s in high-power mode (~18.5 J/TH) 🚀
Up to 25× more efficient cooling compared to air 🌊
Completely silent operation — no fans, no noise 🔇
Requires industrial-grade 3-phase power ⚡

This isn’t DIY mining. Running immersion systems requires specialized infrastructure — dielectric fluids, tanks, pumps, and heat exchange systems. That’s exactly where OneMiners comes in.
