Canaan Avalon A1366I (122TH)

119 to 122 TH/s SHA-256 depending on chip binning (113, 119, and 122 TH/s variants exist). 3,570W power consumption and approximately 29.26 to 30 J/TH efficiency. ±5 percent hashrate and power tolerance. Overclocking potential up to approximately 165 TH/s per Apexto documentation, though this increases power draw proportionally and requires adequate immersion cooling capacity.

No. The "I" in A1366I stands for Immersion. This miner is designed to operate fully submerged in dielectric fluid (transformer oil) inside an immersion cooling tank. It does not contain fans and cannot be operated in open air like standard ASIC miners. MM's listing shows "Air" cooling type and 35 dB noise level, which is incorrect. The miner itself produces near zero noise when submerged. Any sound comes from the external circulation pump and heat exchanger, which are separate infrastructure components.

An immersion tank (commercial or custom built) sized for the miner, 40 to 80 liters of dielectric fluid per unit (SINOPEC I-40 Transformer Oil or equivalent single phase immersion fluid), a circulation pump with adequate flow rate, a heat exchanger (outdoor dry cooler or indoor liquid to liquid), plumbing with fittings, and temperature monitoring. Total infrastructure CapEx per unit: approximately $500 to $2,000 depending on scale. Multi unit tanks amortize cost over more miners. For operators already running immersion, adding an A1366I is incremental.

At standard residential rates ($0.08 per kWh), no. MillionMiner calculator shows -$2.33 daily. At $0.05 per kWh: marginally positive at approximately +$0.25 daily. At $0.03 per kWh: approximately +$1.96 daily. The A1366I reaches positive economics at approximately $0.05 per kWh. However, at 29.26 J/TH efficiency, the daily revenue per dollar of electricity is significantly lower than current generation hardware. The value proposition is the extremely low per terahash acquisition cost ($3 per TH from Canaan direct) for operators with cheap electricity.

Bitmain S21 XP at 270 TH/s, 13.5 J/TH, $4,051 ($15 per TH). Bitdeer A4 Pro Air at 336 TH/s, 10.9 J/TH. The A1366I at 122 TH/s, 29.26 J/TH, approximately $357 ($3 per TH). Current gen delivers 2 to 3 times better efficiency and 2 to 3 times more hashrate per unit, but costs 4 to 5 times more per terahash. For operators with $0.03 to $0.05 electricity, the A1366I's ultra low acquisition cost generates positive returns that higher efficiency hardware achieves faster but at higher CapEx.

200 to 300V AC at 50 to 60 Hz. No 110V support. At 3,570W on 220V draws approximately 16.2 amps. Standard commercial or industrial 220V+ circuits. North American residential typically provides 240V on dedicated dryer circuits, which works within the voltage range. Most immersion deployments use 220V+ infrastructure regardless.

20 to 50 degrees Celsius per ASIC Marketplace and CryptoMinerBros. This refers to dielectric fluid temperature, not ambient air temperature. The immersion fluid should be maintained between 20 and 50 degrees Celsius through the heat exchange system. MM lists 5 to 45 degrees Celsius which appears to use the wrong reference (ambient air for air cooled, versus fluid temperature for immersion).

Approximately 292 x 172 x 281 mm. Weight: 9.7 kg per Mining Now and Bitcoin Merch, 11.3 kg per ASIC Marketplace and CryptoMinerBros (discrepancy may reflect with or without mounting hardware). Compact for an immersion unit. The miner submerges into the tank and the tank dimensions determine facility footprint, not the miner dimensions alone.

Canaan Inc. (NASDAQ: CAN), creator of the first commercial Bitcoin ASIC in 2013 (Avalon). Canaan IPO'd on NASDAQ in November 2019. The A1366I uses Canaan's A13 chip generation with immersion cooling design. Canaan has invested significantly in immersion as a product strategy, offering immersion variants (the "I" suffix) across multiple chip generations alongside their standard air cooled lineup.

All SHA-256 proof of work cryptocurrencies. Primary: Bitcoin (BTC). Secondary: Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Peercoin (PPC), DigiByte (DGB SHA-256), Namecoin (NMC). AuxPoW merged mining through compatible pools allows simultaneous BCH and NMC revenue without reducing BTC hashrate.

No. The A1366I has no fans and no air cooling capability. Operating it in open air without immersion fluid will cause immediate thermal shutdown or chip damage. The unit must be fully submerged in compatible dielectric fluid inside a properly configured immersion cooling tank with active circulation and heat exchange. There is no workaround for this requirement.

Canaan specifies SINOPEC I-40 degree Celsius Transformer Oil for single phase immersion cooling. Compatible alternatives include Engineered Fluids ElectroCool, Shell Diala S4 ZX-I, and other dielectric transformer oils rated for electronics cooling. Do not use water, mineral oil not rated for electronics, or cooking oils. The fluid must be non conductive, thermally stable, chemically inert to circuit board materials, and rated for the operating temperature range.

A1566I at 249 TH/s and 18.1 J/TH (A15 generation immersion). A1366I at 122 TH/s and 29.26 J/TH (A13 generation immersion, this product). The A1566I delivers approximately double the hashrate at 38 percent better efficiency from a newer chip generation. The A1366I costs dramatically less per terahash ($3 versus approximately $10+ per TH). Both use the same immersion infrastructure. For operators with existing immersion tanks, swapping A1366I units for A1566I units doubles hashrate per slot at better efficiency. For operators building new, the A1366I offers the lowest CapEx entry to immersion Bitcoin mining.

Immersion deployment differs fundamentally from air cooled setup. Assemble immersion tank, fill with dielectric fluid to appropriate level. Lower the A1366I into the tank ensuring full submersion. Connect 200 to 300V power cable (routed through tank pass through). Connect Ethernet cable (routed through tank pass through). Start circulation pump. Allow fluid to reach operating temperature (20 to 50 degrees Celsius). Find miner IP through Canaan IP reporter or router DHCP. Configure SHA-256 pool URL and BTC wallet. Verify hashrate stabilizes at 119 to 122 TH/s. First time immersion setup: plan several hours including tank preparation.

Every major SHA-256 pool accepts the A1366I through standard Stratum protocol. Foundry USA, AntPool, F2Pool, ViaBTC, Braiins Pool, Luxor, OCEAN, and all SHA-256 compatible pools. No hardware compatibility considerations. Pool selection is pool preference, not hardware limitation.

Canaan Avalon firmware ecosystem is limited compared to Bitmain. BraiinsOS+ does not support Canaan hardware. Most A1366I operators run stock Canaan firmware. Immersion deployment adds an additional consideration: firmware modifications to fan control are irrelevant since there are no fans, but voltage and frequency tuning for overclocking requires validated immersion cooling capacity.

MillionMiner hosting facilities would need immersion cooling infrastructure to host the A1366I. Standard air cooled hosting racks do not accommodate immersion units. Verify with MillionMiner whether they operate immersion cooling facilities before planning hosted A1366I deployment.

Immersion maintenance is different from air cooled. No dust cleaning (no fans, no particulate ingress). Periodic fluid level checks (evaporation is minimal but occurs over months). Annual fluid quality testing (dielectric strength, acidity, moisture content). Pump and heat exchanger maintenance per manufacturer schedule. The miner itself requires minimal attention when properly submerged. Immersion units typically show longer component lifespans than air cooled equivalents due to eliminated thermal cycling and dust exposure.

Only if you have or are prepared to build immersion cooling infrastructure AND access electricity at $0.05 per kWh or below. The A1366I is not a plug and play device. It requires significant ancillary equipment and knowledge to deploy. At $357 ($3 per TH) from Canaan direct, it is the cheapest per terahash entry to immersion Bitcoin mining available. For operators already running immersion tanks, adding A1366I units at this price point provides hashrate at ultra low CapEx. For operators without immersion experience, the infrastructure learning curve and CapEx are substantial barriers.
