Canaan Launches Submerged Liquid-Cooled Bitcoin Miner, Noiseless Device Boasts 50 Terahash

The publicly listed ASIC mining rig manufacturer, Canaan, has announced the launch of a new submerged liquid-cooled bitcoin miner called the Avalonminer A1066I. Canaan claims the new immersion cooling miner is noiseless and capable of significant overclocking, as the miner’s cooling system increases power efficiency by 78%.

The China-based and Nasdaq-listed bitcoin mining rig manufacturer, Canaan, has revealed a new bitcoin miner with some interesting attributes. The new miner is called the Avalon Immersion Cooling Miner (A1066I) and its components are designed to operate while being submerged under liquid coolant.

According to Canaan’s web page stats, the submerged liquid-cooled Avalonminer A1066I processes bitcoin and other SHA256 coins at around 50 terahash per second (TH/s). The latest Avalonminer also pulls 3400W off the wall, and claims to deliver a power efficiency of 64 joules per terahash (J/TH).

“The Immersion Cooling Miner (ICM) boasts an overclocking ratio of up to 45%,” Canaan’s website specifications note. “Its single module only requires two hash boards which provides computing capabilities equivalent to three air-cooled hash boards— offering significant cost-efficiencies per terabyte for customers.”

Canaan specifications indicate that the ICM is also capable of running 90 mining module deployments simultaneously. The company details that in comparison to the firm’s Avalonminer A1246 series, which is air/fan-cooled, the ICM sees an increase of up to 78% in power efficiency.

The new ICM machine boasts a noiseless experience as well, as the specifications show the modules run in liquid coolant. Canaan believes that the heat reduction can improve a mining farm’s cooling expenditures, for instance, the costs to run large fans.

Being submersible, the Avalonminer A1066I component operation eliminates dust absorption as well, which is a deterioration factor for high-powered ASIC bitcoin miners. “This [system] helps to reduce electrostatic damage caused by internal microdust particles, thereby prolonging the machine’s lifespan,” Canaan’s web portal says.

Canaan is not the first mining manufacturer to create a water-cooled bitcoin mining rig, however, competitor machines. For instance, reported on Bitmain’s Antminer S9 Hydro that processes hashrate speeds at 18 trillion hashes per second (TH/s). Similarly, the S9’s water cooling system makes the ASIC rig less noisy, it eliminates dust particles, and is more energy-efficient according to the company. However, the 18TH/s Antminer S9 Hydro offers far less terahash than most of today’s top miners.

Like all Avalonminers, Canaan’s webshop does not display the Avalonminer A1066I price tag, and interested customers must contact a Canaan consultant for prices. 50 trillion hashes per second is about half the hashrate output that some of the top-performing mining rigs on the market today produce. For example, Bitmain’s S19 Pro mining rig is the most profitable SHA256 miner with 110TH/s. At around $0.12 per kilowatts per hour (kWh), the S19 Pro (110TH/s) makes over $19 a day.

Canaan’s Avalonminer 1066 produces roughly the same output as the submerged hydro-cooled Avalonminer A1066I, as it processes 50TH/s and pulls 3250W from the wall. At $0.12 per kWh and today’s BTC mining difficulty, 50TH/s makes around 0.000095 BTC per day or around three U.S. dollars using today’s exchange rates.

Second-hand ASIC shops are selling the old 50TH/s air-cooled Canaan units for anywhere between $790 to $899 per unit, so the latest submerged hydro-cooled Avalonminer will likely be more expensive. Moreover, $0.12 per kWh for electricity is a high rate and most profitable operations are getting electricity for $0.06 per kWh or much less.
