The bitcoin exchange rate, electricity prices, the mining restrictions implementation, all these affect the number of mining capacities. However, despite the fluctuations, the complexity of mining is always growing. So the competition for bitcoin mining is also growing. And miners are looking for new solutions to maintain their advantage. One of such solutions is hydrocooling of equipment.

How does the hydrocooling system work?

Modern miners are equipped with fans that direct air through the ASIC to maintain an optimal temperature. Thus, less energy is used to calculate the hash, which reduces electricity costs and increases profits. However, with a large amount of equipment, hot air enters the fans and begins to circulate inside the system raising its temperature. And the higher the miner temperature is, the lower its energy efficiency becomes.

Hydrocooling is a relatively new, proven way to maintain the optimal temperature of the equipment. The coolant circulates through a water block and a special plate, thereby removing heat from the ASIC grids. With minimal liquid costs due to the closed circuit, such a scheme reduces the energy costs of cooling the miner by half.

What are the advantages of hydrocooling over immersion?

Immersion cooling is the process of immersing a miner in a bath with a heat conducting liquid. Usually it’s a dielectric oil. In this case, the heat from the miners is transferred to the oil, which removes it from the equipment. However, in several parameters it’s inferior to hydrocooling.

Energy efficiency

Water has twice the heat capacity than oil, so it removes more heat at the same expense. In addition, dielectric oil is ten times more viscous, which means that strong and powerful pumps are needed for its circulation.


The closed loop system consumes about 10 liters of water during its entire service life. In comparison, submersible systems need more than 100 liters of dielectric oil. As a result, hydrocooling consumes 97% less liquid for operation than immersion cooling.

Environmental friendliness

In the context of the green agenda, the use of hydrocooling is much preferable. Water cools more efficiently than oil, saving electricity. Moreover, it’s a renewable resource that is non-toxic and biodegradable, which for sure cannot be said about dielectric oil being produced on the basis of refined petroleum products.

Hydrocooled miners

Hydrocooling has become an increasingly popular technology in recent months. For example, Bitmain, which is one of the largest manufacturers of mining equipment in the world, has several miners with a hydrocooling system in its assortment. These are Antminer S19 XP Hydro and Antminer S19 Pro+ Hydro, which differ from each other in hashrate and energy efficiency.

“Hydrocooled miners are the future of mining. The technology provides high hashing speed, high stability and low error rate. Miners who use data centers with a hydrocooling system can mine all year round”
