Bitmain, a well-known cryptocurrency equipment provider, officially announced the release of its flagship product Antminer S9 Hydro. It is the eighth product launched this year, after the introduction of Antminer S9i, ANTBOX, and Z9mini, etc.
Antminer S9 Hydro masterminded a water cooled system, creating a new mining model with low noise and high energy savings. This new miner supports the SHA256 algorithm and can mine cryptocurrencies such as BTC and BCH.
The Antminer S9 Hydro has a rated hash rate of 18T and a wall power consumption of about 1728W.
Unlike traditional air-cooled miners, S9 Hydro adopts a water cooled system for heat dissipation and it can mine along with a specific power source: the APW5. Individuals or families can use an S9 Hydro-Hex external water circulation module for heat dissipation, while in large mining farms, low noise and high energy saving mining effects can be achieved with an outdoor water source.
For the first time, Antminer S9 Hydro is adopting a water cooling design available for heat dissipation. Thanks to the customized and high-precision water cooling module, S9 Hydro can support the direct introduction of an outdoor water source that meets the water quality requirements and quickly cools down the computing boards and other components inside the miner. During operation, the chip temperature difference is only around 5°C, which can greatly improve the performance and stability of the miner.
Mainly focusing on noise reduction and energy saving, S9 Hydro helps to decrease the maintenance cost of mining farms
Antminer S9 Hydro also performs strongly in terms of noise reduction. The water cooling system reduces not only the internal temperature of the miner but also most of its noise during the operation. Data shows that under the same working temperature, S9 Hydro can decrease the noise by up to 20dB compared with air-cooled miners.
In large mining farms equipped with an outdoor water source, the reduction of chip temperature will help save about 8%-12% of the electricity, an obvious energy-saving advantage. Unlike the use of fans for air-cooled miners, the water cooling system can directly enter the inside of the miner to dissipate heat and ensuring the long-term operation stability.
In addition, S9 Hydro also has the advantages of dust proofing and easy maintenance. More than 95% of the power consumption can be moved external via the water circulation system, which greatly reduces the required air volume of the miner, effectively avoids dust deposits inside the machine, and decreases the risk of short circuit or corrosion of internal components. The innovative design of S9 Hydro contributes to the maintenance of large mining farms and the reduction of operating costs.
