Antminer S21++ Cooling Requirements
The Bitmain Antminer S21++ is air-cooled. It pulls cool air in one end and exhausts hot air out the other, so a deployment needs strict hot-aisle / cold-aisle separation, sufficient CFM per unit, and filtration to keep dust off the hashboards.
Air-cooled units are the simplest to install — no plumbing, no fluid — which makes them the practical choice for smaller sites, pilot deployments and containers that already have fan-wall ventilation. Keep intake temperatures within the manufacturer's operating range to avoid thermal throttling.
The trade-off is noise and density. Expect industrial noise levels at full load, which rules out residential and most office environments, and expect lower hashrate per square metre than an equivalent hydro or immersion setup.

Bitmain Antminer S21++ vs Comparable Miners
How the Bitmain Antminer S21++ compares with the closest alternatives MinersDeals supplies on hashrate, power draw, efficiency and cooling.
| Model | Hashrate | Algorithm | Power | Efficiency | Cooling | Release |
|---|---|---|---|---|---|---|
| Bitmain Antminer S21++ | 216 TH/s · 225 TH/s · 235 TH/s | SHA-256 | — | — | Air cooling | — |
| Bitmain Antminer S21 Pro+ | 234 TH/s · 245 TH/s | SHA-256 | — | — | Air cooling | — |
| Bitmain Antminer S21 | 151 TH/s · 175 TH/s | SHA-256 | — | 17.5 J/TH (rated) | Air cooling | — |
| MicroBT WhatsMiner M60S++ | 206–226 TH/s · 228 TH/s | SHA-256 | — | — | Air cooling | — |
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.
