A single modern ASIC can generate more income than a farm of eight high-end GPUs. For a broader comparison of today’s top options, see our guide to the best ASIC miners for cryptocurrency mining in 2025. However, it also produces roughly double the noise, making home installation almost impossible. To deal with this, some miners move their rigs into separate facilities or use professional mining hotels. But there’s a simpler solution: purchase an ASIC with water cooling. Even if it runs in the next room, the sound will hardly bother you.
The first water-cooled ASICs appeared years ago, but factory-produced models used to be rare. Today, though, the market offers plenty of ready-made options. In this article, we’ll explore what makes water-cooled ASICs different and why they are worth considering.
This information will be especially useful if you’re planning to mine Bitcoin or other SHA-256-based cryptocurrencies, or if you’re thinking about replacing outdated mining equipment. Water-cooled devices may also soon expand into Scrypt, Ethash, and other algorithms.

What Is Water Cooling For An ASIC? How It Works
It’s important not to confuse water cooling with immersion cooling. In a water-cooled ASIC, the principle is similar to a car engine: coolant circulates through a closed loop, without ever touching the chips directly.
This means a water-cooled ASIC can be connected directly to plumbing and drainage systems, and such mining machines can even be used for heating homes or utility spaces. We’ll return to that topic later, but first let’s look at the available water-cooled ASIC models.
Ready-made Water-cooled ASICs
Some enthusiasts build DIY systems, but creating a proper water-cooling setup for an ASIC is much more complex than simply submerging the machine in mineral oil. For most miners, it’s easier to purchase a factory model such as Bitmain’s S19 Pro+ Hyd or the newer S21 Hydro, both equipped with built-in radiators.
Manufacturers and models
Currently, water-cooled ASICs are produced by Bitmain and MicroBT. Below is a list of models and their specifications:
| Model | Hashrate (TH/s) | Power (W) | Price ($) |
| Bitmain Antminer L11 Hyd 6U | 33 GH/s | 5676 | 16,999 |
| Bitmain Antminer S23 Hyd | 580 | 5510 | 13,400 |
| Bitmain Antminer S21 XP+ Hyd | 500 | 5500 | 13,800 |
| Bitmain Antminer S21 XP Hydro | 473 | 5676 | 9696 |
| Bitmain Antminer S21+ Hydro | 319 | 4785 | 4657 |
| WhatsMiner M63 | 360 | 7200 | 8431 |
| Bitmain Antminer S21 Hydro | 335 | 5360 | 8375 |
| MICROBT WhatsMiner M53S++ | 320 | 7040 | 7360 |
| Bitmain Antminer S19 XP Hydro | 257 | 5345 | 5911 |
| WhatsMiner M33S++ | 242 | 7480 | 5192 |
| WhatsMiner M33S+ | 216 | 6820 | 4634 |
| Bitmain Antminer S19 Pro+ Hyd | 191 | 5252 | 2229 |
| Bitmain Antminer S19 Hydro | 151 | 5230 | 1550 |
| Bitmain Antminer T19 Hydro | 145 | 5438 | 2002 |
DIY Modification and Retrofitting
As shown in the comparison tables, water-cooled ASICs are designed exclusively for the SHA-256 algorithm and usually come at a premium price. Technically, you can build one yourself, provided you have the skills and expertise. But it’s a risky task: a small mistake could lead to leaks, damaging not only the ASIC but also your electrical system. The setup requires a radiator, a cooling chamber, and pipes or hoses for circulation. While some miners try draining hot water and replacing it with cold, this method is costly. A closed-loop system with a cooling tower is far more efficient.
Home engineers often use car radiators or split-system casings. Some even adapt their systems to provide heating for a home. In fact, a water-cooled ASIC can work as a kind of improvised “electric boiler.”
Cost of Installing Water Cooling On an ASIC
If you build it yourself, a water-cooled ASIC will cost less than a factory-made Hydro model. The exact price depends on components and materials. Alternatively, you can buy a ready-made water block from a specialized store. This will be more expensive but is a safer option for users without technical skills.
Where to buy components
Each ASIC model needs its own water block design. Ready-made hydro kits are available from global online stores such as:
- BT-Miners.com – offers water-cooled solutions for Antminer S19, L7, and WhatsMiner devices.
- AsicMarketPlace.com – sells a variety of hydro blocks and custom kits for different ASIC models.
Other specialized vendors may also provide DIY kits or custom solutions, so it’s worth comparing several options before purchasing.
Using Water-cooled ASICs For Home Heating
In theory, water-cooled ASICs can be connected to a “warm floor” heating system or regular radiators with forced circulation. The ASIC can function as the main boiler or a backup one. The key is to maintain stable coolant temperatures without damaging the miner. It’s also important to design a system that allows disconnecting the ASIC from the heating circuit during summer months. Still, their core purpose remains unchanged: efficient cryptocurrency mining, which depends on connecting to reliable mining pools
Such work should ideally be carried out by a qualified technician, though experienced users can attempt it themselves. There is plenty of online content available on this subject.
Conclusion
Overall, water-cooled ASICs offer quieter operation, better overclocking potential, and improved reliability. In some cases, they can even be integrated into a home heating system as a substitute for an electric boiler. Still, their core purpose remains unchanged: efficient cryptocurrency mining.
