Description

The Antminer S21 Imm model from the world's leading manufacturer Bitmain is a high-performance solution designed for professional mining. This device combines advanced chip architecture, exceptional reliability, and optimized power consumption, making it one of the most sought-after tools in the digital asset mining industry. The model was released in December 2024.


Technical Specifications and Performance

The Antminer S21 Imm is powered by innovative components that ensure stable operation even under peak loads.


Key metrics of the device:

  1. Algorithm: Operates on the SHA-256 algorithm, which has proven to be one of the most secure and profitable in the network.
  2. Hashrate: The nominal computing power is 301Th, allowing it to compete effectively in today's network complexity conditions.
  3. Power Consumption: The device power consumption is locked at 5568.5 W, providing a perfect balance between performance and electricity costs.
  4. Energy Efficiency: The efficiency metric stands at 18.5 j/Th, which is a key factor for a fast return on investment.


Supported Assets

Due to the SHA-256 algorithm, this miner allows you to mine a wide range of cryptocurrencies. The list of the most relevant coins includes: Bitcoin Cash, Bitcoin, Fractal Bitcoin, BitcoinSV, Terracoin, Namecoin. This gives the owner flexibility in choosing a mining strategy and the ability to switch between assets depending on the current market situation.


Cooling System and Operating Conditions

The operational stability of an ASIC miner directly depends on the quality of heat dissipation. This model features an advanced cooling system.


The device is prepared for submersion into a specialized dielectric liquid. Immersion cooling is the pinnacle of engineering thought in mining. The liquid envelops all components, ensuring uniform heat dissipation and protecting the hashboards from dust, moisture, and static electricity. This eliminates the risk of local overheating ("hot spots") and allows for safe overclocking, increasing the hashrate above factory settings while maintaining a stable temperature.


Advantages of the Antminer S21 Imm model

  1. Durability: The use of high-quality chassis materials and wear-resistant components guarantees a long equipment lifecycle.
  2. Intelligent Management: The built-in software allows tracking chip status, fan rotation speed (if applicable), and current revenue in real-time.
  3. Fast Configuration: An intuitive web interface allows launching the mining process just a few minutes after the first power-up.


Summary


Bitmain Antminer S21 Imm is the benchmark of quality in the mining world. The device is perfectly suited both for scaling existing farms and for those looking for the most effective solution to start. A high hashrate combined with clever power consumption makes this model a strategically advantageous acquisition for the long-term perspective.

Frequently Asked Questions

The Bitmain Antminer S21 Imm features cooling based on immersion fluid. Immersion models can only be operated inside a specialized dielectric fluid tank (bath).. To initiate mining, plug in the LAN cable, scan your local network for the miner's IP using an ASIC Tool, open the web dashboard, and enter your target pool stratum addresses.
Upon conversion, the computing power of 301 Terahash/s is equivalent to 301 000 000 000 000 hash/s, 301 000 000 000 kilohash/s, 301 000 000 Megahash/s, 301 000 Gigahash/s, 0,30 Petahash/s. Depending on the coin algorithm, the baseline operational output denomination might be displayed in different network standards. To quickly convert any hashrate, solution, or graph volumes without manual calculations, use our dedicated hashrate converter tool on the TrustMining website.
Given the current network difficulty of 140,577,680,051,919 and a block reward of 3.125 BTC, a single Bitmain Antminer S21 Imm 301 Th/s will take approximately 6921 days to successfully secure 1 full Bitcoin. The device yields roughly 0.00014448 BTC or 14448 satoshi per day on average.
The Antminer S21 Imm rig is exceptionally data-efficient, utilizing only about 50 to 150 MB of network data per month per machine, as it only sends small textual cryptographic shares (work updates) to the pool server. The core requirement is connection stability and minimal network latency rather than raw speed (Ping to the pool under 50-80 ms). ASICs must be connected exclusively via a **wired LAN cable** (Ethernet).
If adequate cooling is maintained (ASIC chips under 75-80°C), dust is cleared regularly (every 6 months), and grid voltage stays stable, the Antminer S21 Imm can operate reliably for **3 to 5 years**. The most common components requiring eventual routine replacement are cooling fans.
