Bitcoin mining is heavily criticized by the general public because, if it isn’t raising the cost of computer chips, it is wasting too much energy. If it’s not producing computation that is useless and cannot be used for anything else, it’s making too much noise. Bitcoin miners, such as the Bitmain Antminer S19 series miners, contribute computing power to the network in a fiercely competitive race around the world. They carry out calculations continuously day and night to maintain the chain’s integrity and the addition of new blocks. Let’s examine what causes Bitmain Antminer S19 series miners to be so loud and how to do so.

How Loud Are Antminer S19 Series Miners?
The Antminer S19 series miners’ noise levels range between 50 DB and 75 DB; by comparison, the noise level is similar to a food blender or a loud vacuum. Watch the video below to get an idea of how loud a bitcoin miner can be. It demonstrates how loud the Bitmain Antminer S19j Pro is.
There is no fan and only 50db of noise is produced by the Bitmain Antminer S19 Pro Hyd (177Th), Bitmain Antminer S19 Pro+ Hyd (198Th), Bitmain Antminer S19 XP Hyd (255Th), and Antminer S19 Hydro (158Th). For your house, the miner is ideal.
Why Are Antminer S19 Series Miners So Loud?
The cooling fans on all miners cause them to all make a lot of noise, not just the Antminer S19.
Why does bitcoin mining make so much noise to the uninitiated when it uses complex computers to solve extremely difficult computational math problems? Modern laptops and desktop computers don’t even make a sound when they’re operating.
Yes, personal computers are now much quieter than they once were, but aside from those who use them for video editing, you’re not really pushing them to their limits. Not exactly going to overload your device are your email client and web browsing.
If you’ve ever used a gaming laptop or a CPU, you’d be aware that under heavy loads, the GPU and the CPU have a tendency to overheat, forcing the chassis’s fans to spin at maximum speed in an effort to remove as much heat as possible.
In the event that you’re in a room alone, that process can be quite loud.
But with bitcoin, you want to push the button as hard as you can. Finding a solution to the issue is what the computer aims to do. A block subsidy of bitcoin is given to the first computer to find the answer, and the process then moves on. You must push out as many computations as you can in the hope of making a profit because the race against time is a time-based event that occurs roughly every ten minutes.
The computer needs to run at a faster rate to output more computation, which uses more electricity and produces heat. The majority of the noise is generated by cooling fans spinning at maximum speed to supply enough cool air to the various parts inside the mining machine to maintain its cooling, which is necessary to prevent circuits from being damaged by heat.
Personal computers are no longer used for bitcoin mining. Today, the hardware needed to run this mining setup is specialized to do just one thing—mine bitcoin. An application-specific integrated circuit (ASIC) is needed to set up a mining rig. All mining-related extraneous components are removed from these rigs, leaving only the essential components that maximize hash power production.
Practical Methods for Noise Reduction and Cooling of Bitmain Antminer S19 Series Miners
ASIC miner noise not only disrupts sleep but also physical and mental health, as well as neighborly and family relationships. The GPU miner doesn’t make much noise. The ASIC miner can generate noise levels of over 80 decibels. A 120mm cooling fan, whose speed can reach above 6000 RPM, is used by the majority of miners, including the Ebit E9, Antminer S9, A3, and D3. There is a lot of noise created by the fan blades rapidly cutting the air. As an illustration, consider the Antminer S9: the temperature outside is higher than 25 degrees, and the noise level can exceed 95 decibels. When the door is closed in the room, the noise of the miner can be transmitted to the ears of neighbors and can be heard clearly at a distance of 300 meters without being blocked during the still night. The enormous number of miners used their superhuman intelligence to create various noise reduction equipment in order to lessen the noise of their mining rigs. The following are more typical noise reduction schemes:
Straight-through Noise Reduction Box
The straight-through noise reduction box is the earliest noise reduction scheme, intuitive and straightforward, and can reduce the noise by more than 20 decibels;
Advantages: simple structure, simple production process;
The miner’s control board is prone to overheating in a confined space, and the area is large and has a low fire safety factor.
Labyrinth Noise Reduction Box
The labyrinth-shaped noise reduction box has the best noise reduction effect out of all the noise reduction techniques, but it takes several turns for the sound to come through! Therefore, it is acceptable to let the miner sleep in the bedroom. However, it is difficult and expensive to produce, weighs more than 80 kilograms, and has a larger surface area than one square.
Advantages: good mute effect;
Large area, low fire safety factor, high cost, and miners’ blazing temperatures are drawbacks.
Water-cooled, Oil-cooled Noise Reducer
The fundamental idea behind this scheme is that the heat produced by the hash board chips flows in a fixed pipe using water or oil as the heat carrier. However, the adoption of oil- and water-cooled noise reduction strategies is not very high. It is still necessary to perform air-cooled fan heating on the water and oil heat carriers due to the influence of the law of conservation of energy. The amount of air-cooled exhaust needed depends on the miner’s power. More than 12 fans with a speed of 3000 rpm are typically required for miners more powerful than 1000W.
One of the Antminers that uses water cooling to lower temperatures and noise is the AntminerS19 Hydro.
Advantages: The air-cooled exhaust can be placed outdoors to isolate noise;
A few drawbacks include complex production, voiding of the miner’s warranty, high price, and air-cooled heat dissipation.
Wind Tunnel Noise Reducer
The wind tunnel noise reducer has a simple structure. In order to keep the main board operational, a fan speed simulator is used. After that, a negative pressure fan with an air volume of more than 650 square meters can be connected. The wind tunnel type has a small footprint and a sizable noise reduction effect. For miners greater than 1600W, a single wind tunnel cannot be used. It works for the Antminer series, but the Whatsmienr series needs a bigger wind tunnel because the double wind tunnel pushes the wind.
Advantages: easy installation, noticeable noise reduction effect, no damage to the miner’s warranty, low temperature of the miner, stable work;
Can’t be used with miners that are more powerful than 1600W.
Immersion-type Water Cooling, Oil Cooling
Heat the miner by submerging it in water or oil and using a circulating fan. The result is perfect, and the production difficulty is minimal. The consequences of immersion oil cooling could be disastrous because of the extremely high fire pressure. There is no fire risk with immersion-style water cooling. Even so, the equipment requirements are fairly high, and a deionizer is necessary to keep the water from conducting by continuously removing ions from it.
Advantages: good noise reduction effect, does not destroy the warranty;
Disadvantages include the high cost of water cooling and high risk of fire prevention associated with oil cooling.
ANC Active Noise Canceller
In terms of reducing noise for miners, ANC active noise reduction technology is a bit excessive. The idea is to surround the miners with 16 microphones to capture the noise. Single-chip computer filtering is used to calculate the waveform opposite the noise to cancel it. The ANC active noise reducer currently has more serious flaws. There must be more than 1.5 meters between each device. If not, they will have an impact on one another. The complexity of 16-channel energy conversion, calculation, and acquisition has surpassed all expectations. This technology will produce more notable results if it is applied to noisier situations.
Advantages: noticeable noise reduction effect;
Large area and high cost are drawbacks.
Miner Mute Machine
The noise produced by the high-speed rotating cooling fan blades is the most bothersome thing in the home environment. The air needed to cool the processor safely and quietly is provided by the cargo volume. This product is appropriate for urban cryptocurrency mining. To use this product, which has a high heat dissipation efficiency and minimal noise, you only need to remove the miner’s original fan.
The miners’ lack of noise effectively prevents large fans like the Antminer from operating.
Pure copper wire is used in the Antminer Silencer, which has the advantages of high wind pressure, low noise, small size, large air volume (150 watts), quietness, and durability, among other things. High speed is one of three speeds—the others are medium and low. When connecting, kindly look at the motor. Please do not unplug it; if you do, the motor will burn out. There is no plug on this integrated silent machine. The adjustable suction interface, input voltage: 220V, motor power consumption: 150W, is appropriate for the majority of T17 series, Innosilicon series, Avalon 1066, and other integrated miners.
Wide application range, low noise, and large air volume are benefits.
Summary: Reduce the Noise of Bitmain Antminer S19 Series Miners
Contrary to popular belief, bitcoin miners also dislike the noise; whether it’s at your place of business, employment, or home, the noise is grating. Some miners have adapted to the noise pollution. Take the actions we listed above to lessen the noise effects of your Bitmain Antminer S19 series miners.
Is Bitcoin Mining Loud?
You start to hear the roar as you get closer to the mine, which is run by the San Francisco business PrimeBlock. During the day, its low-frequency hum—which, directly outside, may go up to 95 decibels—can make it seem like you’re next to a running motorcycle.
How Do You Cool ASIC Miners?
Cooling ASIC miners is essential to ensure their optimal performance and longevity. ASIC miners generate a significant amount of heat due to their high computational power and energy consumption. Here are some common cooling methods used for ASIC miners:
- Fans: Most ASIC miners come equipped with built-in fans or fan arrays. These fans are designed to provide active airflow and dissipate heat generated by the miners. It’s important to ensure that the fans are clean and functioning properly for efficient cooling.
- Heat Sinks: Heat sinks are metal components with fins that increase the surface area for heat dissipation. They are often attached to the ASIC chips or other heat-generating components on the miner. Heat sinks absorb heat and transfer it away from the chips, allowing for better cooling.
- Ventilation: Ensuring proper ventilation in the mining facility or room is crucial. Good airflow helps dissipate heat effectively. Consider using exhaust fans or installing additional ventilation systems to remove hot air and bring in cool air from outside.
- Liquid Cooling: Liquid cooling is another method used for advanced cooling of ASIC miners. It involves circulating a liquid, such as water or specialized cooling fluids, through a closed-loop system that comes into contact with the heat-generating components. The liquid absorbs the heat and carries it away, providing efficient cooling.
- Immersion Cooling: Immersion cooling is a technique that involves submerging ASIC miners in a non-conductive liquid, such as mineral oil or specialized cooling fluids. The liquid directly absorbs the heat, and specialized systems circulate it away from the miners. Immersion cooling can be highly efficient and allows for better heat dissipation compared to traditional cooling methods.
- Ambient Temperature Control: Keeping the ambient temperature within the mining facility or room under control is crucial for cooling ASIC miners. Higher ambient temperatures can strain the cooling systems and affect the miners’ performance. Consider using air conditioning or other cooling mechanisms to maintain a suitable temperature range.
How Long Do ASIC Miners Last?
The average lifespan of a well-kept, maintained machine can be around 3 to 5 years. ASICs can deteriorate in as little as a few months if they are kept in harsh or unfavorable conditions, though. On the other hand, an ASIC miner’s lifespan can be increased by more than 5 years with proper maintenance.
