How to Make Bitmain Antminer E9 Quieter – Comprehensive Guide

This article will go over several practical techniques for cutting down Bitmain Antminer E9 noise.

One Bitmain Antminer E9 produces noise of between 70 and 75 decibels (dB). Decibel levels scale logarithmically; for instance, if one relatively quiet machine produces 75 dB, ten similarly quiet machines produce 85 dB, and 100 such machines produce 95 dB. The average nightclub keeps the volume at 98 dB, which is so loud that it’s almost uncomfortable, to give you an idea of how loud most nightclubs are.

A 120mm cooling fan with a maximum speed of over 6000 RPM is used to exhaust heat from the Bitmain Antminer E9. There is a lot of noise produced by the fan blades rapidly cutting the air. It occasionally has a jet engine sound to it. Is there a way to lessen the noise the E9 makes? The solutions are revealed as you read on in the article.

Ways to Reduce the Sound of Bitmain Antminer E9

The majority of mine noise is between 60 and 90 dB. The Bitmain Antminer E9’s 72dB noise level is one of the features people adore. Due to the device’s low noise level, it can be used in residential areas. Installing mining equipment close to users’ homes is preferred by the vast majority of users. If you intend to run multiple machines at once, you must still reduce the noise.

Numerous miners used their superhuman intellect to invent various pieces of noise-canceling equipment in order to lessen the noise produced by 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 size and fire safety aspects of the situation are issues.

Labyrinth Noise Reduction Box

The labyrinth-shaped noise reduction box, which reduces noise the best out of all the techniques, requires a number of turns. The Bitmain E9 is able to go to sleep in the bedroom as a result. It is more than 80 kilograms in weight, has a surface area greater than a square, and is challenging and expensive to produce.

Advantages: good mute effect;

Drawbacks include the size of the area, the absence of fire safety, the high cost, and the miners’ elevated body temperatures.

Wind Tunnel Noise Reducer

The noise reducer for wind tunnels has a simple structure. The main board is kept running by a fan speed simulator. Then, a negative pressure fan can be connected for use with an air volume of more than 650 square meters. The wind tunnel design includes a compact footprint and significant noise reduction. Miners that have more power than 1600W can only use one wind tunnel. For the Whatsmienr series, the double wind tunnel is insufficient because it pushes the wind, but it is effective for the Antminer series.

Advantages: easy installation, noticeable noise reduction effect, no damage to the miner’s warranty, low temperature of the miner, stable work;

Cons: Incompatible with miners that have a 1600W or higher power output.

Water-cooled, Oil-cooled Noise Reducer

The fundamental idea behind this system is that heat produced by hash board chips flows in a fixed pipe using water or oil as a heat carrier. The use of water- and oil-cooled noise reduction techniques is uncommon, though. For the purposes of heating water and oil, the law of conservation of energy still requires air-cooled fan heating. Depending on the miner’s power, a specific volume of air-cooled exhaust is required. Usually, more than 12 fans with a 3000 rpm speed are required for miners that are more potent than 1000W.

One of the Antminers that uses water cooling to lower temperature and noise is the S9 Hydro.

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

Complex production, voiding of the miner’s warranty, high cost, and air-cooled heat dissipation are some of the drawbacks.

ANC Active Noise Canceller

In terms of reducing noise for miners, ANC active noise reduction technology is a little over the top. 16 microphones will be installed all around the miners to capture any noise they make. In order to filter out noise, single-chip computing determines the waveform opposite the noise. The ANC active noise reducer currently has more significant drawbacks. Ideally, there should be more than 1.5 meters between each device. They will obstruct each other’s path if they don’t. The degree of 16-channel energy conversion, calculation, and acquisition complexity exceeded all expectations. This technology will produce more noticeable results in louder environments.

Advantages: noticeable noise reduction effect;

Large area and high cost are limitations.

Immersion Type Water Cooling, Oil Cooling

The miner can be heated by submerging it in water or oil and using a circulating fan. The result is flawless, and the production difficulty is barely perceptible. The outcomes could be disastrous due to the high fire pressure caused by immersion oil cooling. No fire hazard exists when cooling water by immersion. There are still significant equipment requirements even though a deionizer is necessary to maintain the water continuously ion-free and non-conductive.

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

Conveniences: Water cooling is more expensive and more effective at putting out fires than oil cooling.

Miner Mute Machine

The high pitch sound that cooling fan blades rapidly rotating creates is the most annoying aspect of living in a house. In order to keep the processor cool and make as little noise as possible, the cargo volume delivers the necessary air. The mining of cryptocurrencies in urban areas is suitable for this product. Installing this product, which has a high heat dissipation efficiency and is quiet, only requires removing the miner’s original fan.

The silence of the miners effectively prevents large fans like the Antminer from operating.

Antminer Silencer

Pure copper wire is the only material used in the Antminer Silencer, and it has several benefits including high wind pressure, low noise, small size, large air volume (150 watts), quietness, and durability. There are three speeds: high, medium, and low. High speed is most common. If you are connected, kindly check the motor. Please don’t disconnect it; doing so will damage the motor. There are no cords at all on this cordless device. The adjustable suction interface, which has a 220V input voltage and a 150W motor power consumption, is compatible with the majority of integrated miners from the T17 series, Innosilicon series, Avalon 1066, and other manufacturers.

Large air volume, low noise, and a wide range of applications are advantages.

Why is Bitcoin Mining So Noisy?

When using sophisticated computers to solve extremely challenging computational math problems, why does bitcoin mining sound so loud to those who are not familiar with it? These days, aren’t laptops and desktops as silent as they can be?

Despite the fact that personal computers are now noticeably quieter than they once were, unless you’re a video editor, you’re probably not making the most of them. 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 probably aware that under extreme load, 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.

It can get quite loud during that process if you’re the only person in the room.

But when it comes to bitcoin, you want to apply all possible pressure. The computer’s goal is to find a solution. The first computer to determine the solution receives a block subsidy in bitcoin, and the process continues from there. The race against time is repeated roughly every ten minutes, so to make a profit you need to push out as many computations as you can.

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

The bitcoin mining market for personal computers has long since vanished. 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 stripped of all non-essential parts, leaving only those that are optimized to generate hash power.

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.

Because there is only one standalone miner, you will be driven insane by the noise of a blender or vacuum running nonstop 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.
