The Power of Immersion Cooling

By removing high-speed fans and submerging the hardware in specialized dielectric oil, the Antminer S21 Imm 300T offers several critical advantages:

  • Silent Mining: Zero fans mean the unit operates in near-total silence, perfect for noise-restricted zones.

  • Extended Life Cycle: Immersion protects sensitive chips from dust, humidity, and oxidation, drastically reducing maintenance costs.

  • Superior Heat Management: Liquid cooling is significantly more efficient than air, preventing thermal throttling and ensuring 24/7 stability.
