How to Reduce Bitmain Antminer L3 Series Noise-Full Guide

Several workable methods for reducing Bitmain Antminer L3 Series noise will be discussed in this article.

Everyone is vying for a share of the wealth created by Bitcoin. But many people choose to mine independently and join the mining army because purchasing coins involves too much risk. Everyone is aware of how difficult it is to buy mining equipment these days, but mining machines must be used for mining. But even owning a mining machine is a very painful thing. The noise level is incredibly loud when the mining machine is running.

The Bitmain Antminer L3 Series uses a 120mm cooling fan with a maximum speed of 6000 RPM to dissipate heat. The fan’s blades are rapidly cutting the air, which makes a lot of noise. There are times when it may sound like a jet engine. Is the Bitmain Antminer L3 Series’ noise level adjustable? Continue reading the article to discover the solutions.

Ways to Reduce the Sound of Bitmain Antminer L3 Series

The Bitmain Antminer L3+ and Antminer L3++ have an average noise level of 70 dB.

When the environment is warmer than 25 degrees, noise levels can exceed 95 decibels. When the room door is closed, the Bitmain Antminer L3’s noise can be heard clearly and unhindered 300 meters away, as well as by neighbors. In order to reduce the noise made by miner rigs, many miners used their superhuman intellect to develop a variety of noise-reduction tools. 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;

There are issues with the size of the area and the fire safety factor, and the miner’s control board is prone to overheating in a small space.

Labyrinth Noise Reduction Box

The labyrinth-shaped noise reduction box has the best noise reduction effect of all the noise reduction methods, but the sound doesn’t come out until you turn it around several times! Therefore, it is acceptable to let the Bitmain Antminer L3 sleep in the bedroom. But because it weighs more than 80 kilograms and has a surface area greater than a square, producing it is difficult and expensive.

Advantages: good mute effect;

The disadvantages include the size of the area, poor fire safety, high cost, and the oppressive behavior of the miners.

Water-cooled, Oil-cooled Noise Reducer

This scheme’s basic premise is that heat generated by hash board chips flows in a fixed pipe using water or oil as the heat carrier. However, the use of water- and oil-cooled noise reduction techniques is not very widespread. Due to the influence of the law of conservation of energy, air-cooled fan heating is still required for the water and oil heat carriers. The power of the miner determines the required volume of air-cooled exhaust. For miners larger than 1000W, more than 12 fans with a 3000 rpm speed are typically needed.

The S9 Hydro is one Antminer that uses water cooling to reduce noise and temperature.

Advantages: The air-cooled exhaust can be placed outdoors to isolate noise;

Drawbacks include complex production, voiding of the miner’s warranty, high cost, and air-cooled heat dissipation.

Wind Tunnel Noise Reducer

The structure of the wind tunnel noise reducer is simple. Using a fan speed simulator to maintain the main board’s functionality, a negative pressure fan with an air volume of more than 650 square meters can then be connected. With a modest environmental impact and significant noise reduction, the wind tunnel design excels. A single wind tunnel cannot be used to operate miners larger than 1600W. It works for the Antminer series, but the Whatsmienr series requires a larger 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;

Cons: Incompatible with mining equipment that produces more power than 1600W.

Immersion Type Water Cooling, Oil Cooling

When the miner is submerged in water or oil, a circulating fan is used to heat it. The production difficulty is hardly noticeable, and the effect is flawless. Because of the intense fire pressure brought on by immersion oil cooling, the results could be disastrous. Water cooling by immersion poses no fire risk. Although a deionizer is required to continuously remove ions from the water in order to keep it from becoming conductive, there are still significant equipment requirements.

Advantages: good noise reduction effect, does not destroy the warranty;

A high risk of fire prevention and a high cost of water-cooling are two drawbacks of oil-cooling.

ANC Active Noise Canceller

The use of ANC active noise reduction technology for noise reduction for miners is perhaps a bit excessive. In order to record any noise the miners make, 16 microphones will be placed around them. The waveform opposite the noise is calculated to cancel the noise using single-chip computer filtering. Presently, the ANC active noise reducer has more significant issues. Every device needs to be at least 1.5 meters apart from one another. If not, they will affect one another. In 16-channel acquisition, computation, and energy conversion, unfathomable levels of complexity have been reached. If used in noisier environments, this technology will yield more notable results.

Advantages: noticeable noise reduction effect;

Costly and large area are disadvantages.

Miner Mute Machine

The most annoying aspect of living in a home is the noise made by the cooling fan blades rotating at high speed. The cargo volume supplies the air required to maintain the processor’s cooling while minimizing noise. Utilize this product to mine cryptocurrencies in populated areas. The only thing needed to use this product, which has a high heat dissipation efficiency and low noise, is to take out the miner’s original fan.

Because the miners are silent, big fans like the Antminer cannot operate.

Antminer Silencer

The only material used in the Antminer Silencer is pure copper wire, which has a number of advantages including high wind pressure, low noise, small size, large air volume (150 watts), quietness, and durability. High speed is the most popular of the three speeds—the others are medium and low. Observe the motor when connecting. Please do not unplug it; doing so will cause the motor to burn out. This integrated silent machine lacks a plug. The majority of T17 series, Innosilicon series, Avalon 1066, and other integrated miners can use the adjustable suction interface; input voltage: 220V; motor power consumption: 150W.

Advantages include a large air volume, low noise, and a broad application range.

Why is Bitcoin Mining So Noisy?

Why, when using sophisticated computers to solve extremely challenging computational math problems, does bitcoin mining make such a racket for the uninitiated? These days, aren’t laptops and desktops as silent as they can be?

Personal computers are quieter than they once were, but unless you’re a video editor, you’re not really utilizing them to their fullest extent. Not exactly taxing on your device are your email client and web browsing.

If you’ve ever used a gaming laptop or a CPU, you’re already aware that when under a lot of stress, the GPU and the CPU tend to overheat, causing the chassis’s fans to spin at maximum speed in an effort to dissipate as much heat as possible.

That process can get quite loud if you’re the only person in the room.

However, when it comes to bitcoin, you should apply all possible pressure. The aim of the computer is to fix the problem. The first computer to find the solution receives a block subsidy in bitcoin, and the process then continues. The race against time is repeated about every ten minutes, so you need to push out as many computations as you can to make a profit.

To produce more computation, the computer must operate at a higher rate, which uses more power and generates heat. Circuits could be damaged by excessive heat if it isn’t properly dissipated. The mining machine’s cooling fans must run at full capacity to keep all of the components cool. Most of the noise originates from this area.

Bitcoin mining on personal computers is no longer a thing. To set up a mining rig, you need an application-specific integrated circuit (ASIC), as the required hardware is currently only designed to mine bitcoin. These mining rigs are built with only the necessary components that are optimized to produce hash power, leaving out everything else.

A typical ASIC’s noise levels range between 50 DB and 75 DB; by comparison, the noise level is similar to a food blender or a loud vacuum.

Since there is only one standalone miner, you will go insane from the constant noise of a blender or vacuum in your home or coming from your neighbor’s home.

When it comes to mining facilities, where hundreds or thousands of these computers are performing calculations and using a ton of processing power, it is not surprising that the whining fan noise would intensify, travel even further, and annoy large populations of people.

Conclusion: Ways to Reduce the Noise of Bitmain Antminer L3 Series

The Bitmain Antminer L3+ and L3++ produce noise of at least 70 decibels, and the closer the distance, the louder the noise becomes, even without multiple mining machines operating simultaneously. Low-frequency whistling in combination with fan noise is very dangerous. Long-term exposure to this environment not only affects the auditory system but also negatively impacts the nervous system, cardiovascular system, digestive system, endocrine system, and other life-threatening systems.

In this post, eight techniques for reducing noise on Bitmain Antminer L3 Series devices are discussed. I hope you found that useful.
