On September 21, Canaan released its A1246 with a hashrate of 90TH/s, a power consumption of 3420W, and a power efficiency of 38J/TH. It is AvalonMiner’s first product with a hashrate of 90TH/s.

Integrated design for better reliability

The 1246 integrates the power supply with the enclosure. Its maximum voltage is 285V, with a frequency ranging from 50 Hz to 60 Hz and alternating current is capped at 16A. The compact aluminum enclosure has a net weight of 12.8 kg. The bare machine dimensions (331 mm × 195 mm × 292 mm) provide greater flexibility and fit various cabinet sizes.

Four fans for better heat dissipation

To improve heat dissipation, the A1246 is equipped with high-temperature-resistant 12038 Cooler Master fans. The front dual fans are the air inlet. Their seven blades further increase the air contact area and pressure, deepening the penetration of air flow to the enclosure while blowing away interior dust. This design effectively prevents dust accumulation over time on the hash boards, which may cause a short circuit due to static electricity.

The fan has a voltage of 12V and a direct current of 4.5A. The rear dual fans will push away warm interior air to achieve better heat dissipation. The external mesh fan can protect maintenance workers from a blade injury caused by accidental contact with its surface.

Latest software and management platform for miners

In terms of software, it is designed to dynamically accommodate changing mining sites to safeguard the operating stability of miners, minimize impacts on the site grid, and extend mining life. What’s more, the new web management platform can monitor the miner’s conditions at any time, while supporting visualization and human-machine interaction. On top of that, the auto alert will detect operating anomalies and shut down the machine when a malfunction significantly affects the hashrate, reducing electric bills.

Safeguards for hashrate

The A1246 has an embedded anti-tamper mechanism. The built-in AI chip, which is in the main control board, analyzes fluctuations in hashrate through intelligent algorithms, adjusts the fan speed, and identifies potential network attacks and loopholes. Moreover, it stabilizes the hashrate to be within a reliable range to prevent hashrate loss.
