Antminer S21 Imm Cooling Requirements
The Bitmain Antminer S21 Imm ships in an immersion configuration: the hashboards are designed to be submerged in a dielectric fluid bath rather than cooled by onboard fans. It cannot be run as a conventional air-cooled unit.
You will need immersion tanks, a dielectric fluid volume appropriate to the tank, circulation pumps, filtration and a heat exchanger loop to reject heat to a dry cooler. Fluid selection, fluid maintenance and tank sealing all matter for long-term reliability.
Immersion removes dust and vibration from the equation, keeps chip temperatures very even, and is the quietest deployment format available. It is usually chosen by operators who already have tank infrastructure or who need to run in hot, dusty or noise-sensitive locations.

Bitmain Antminer S21 Imm vs Comparable Miners
How the Bitmain Antminer S21 Imm compares with the closest alternatives MinersDeals supplies on hashrate, power draw, efficiency and cooling.
| Model | Hashrate | Algorithm | Power | Efficiency | Cooling | Release |
|---|---|---|---|---|---|---|
| Bitmain Antminer S21 Imm | 239 TH/s | SHA-256 | — | — | Immersion cooling | — |
| Bitmain Antminer S21 XP Imm | 300 TH/s | SHA-256 | — | — | Immersion cooling | — |
| MicroBT WhatsMiner M66S | 300 / 302 TH/s | SHA-256 | — | — | Immersion cooling | — |
| Bitmain Antminer S23 Immersion | 442 TH/s | SHA-256 | 5304 W | ≈12 J/TH | Immersion cooling | 2026 (batch dependent) |
Efficiency (joules per unit of hashrate) determines how long a machine stays profitable as network difficulty rises, while total power draw determines what electrical and cooling infrastructure you need per unit. A more efficient miner is not automatically the better purchase — price per terahash, availability and the cost of the cooling infrastructure it demands all feed into the decision.
If you are weighing two of these models against each other, send us your electricity rate, target quantity and site cooling type and we will model the comparison against real availability and pricing.
