How to Make Bitmain Antminer D7 Quieter: Things You Need to Know

This article will outline several doable strategies for minimizing Bitmain Antminer D7 noise.

Everyone wants a piece of the wealth that Bitcoin has generated. However, because buying coins carries too much risk, many people opt to mine independently and join the miner army. Everyone is aware of how difficult it is to purchase mining equipment these days, but mining machines must be used for mining. But even owning a mining machine is a very painful thing. When the mining machine is operating, the noise level is extremely loud.

A 120mm cooling fan that can spin as fast as 6000 RPM is used by the Bitmain Antminer D7 to dissipate heat. There is a lot of noise created by the fan blades rapidly cutting the air. Sometimes, it might sound like a jet engine. Is it possible to lessen the sound of D7? To find the answers, keep reading the article.

Ways to Reduce the Sound of Bitmain Antminer D7

Noise levels can exceed 95 decibels when the surrounding temperature is above 25 degrees. When the door to the room is closed, the Bitmain Antminer D7’s noise can be heard clearly and unobstructed from a distance of 300 meters away, and it can also be heard by neighbors. Numerous miners used their superhuman intellect to create various noise-reduction tools in order to lessen the noise produced by miner 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 there are issues with the size of the area and the 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 the sound doesn’t come out until you turn it around several times! Therefore, it is acceptable to let the miner sleep in the bedroom. But its production is difficult and expensive, and it weighs more than 80 kilograms and has a larger surface area than 1 square.

Advantages: good mute effect;

Large area, poor fire safety, high cost, and miners’ sweltering behavior are disadvantages.

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. The use of oil- and water-cooled noise reduction strategies is not very common, though. 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. Typically, more than 12 fans with a 3000 rpm speed are required for miners that are larger than 1000W.

One of the Antminers that uses water cooling to lower temperatures 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 all drawbacks.

Wind Tunnel Noise Reducer

The wind tunnel noise reducer has an easy-to-understand structure. A negative pressure fan with an air volume of more than 650 square meters can then be connected after the main board is kept operational using a fan speed simulator. The wind tunnel design has a small footprint and a sizable noise reduction effect. Larger miners than 1600W cannot be operated in a single wind tunnel. It works for the Antminer series, but the Whatsmienr series needs 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: Not compatible with miners that have a power output of more than 1600W.

Immersion Type Water Cooling, Oil Cooling

Heat the miner with a circulating fan while submerging it in water or oil. The effect is perfect, and the production difficulty is minimal. The consequences could be disastrous because of the high fire pressure associated with immersion oil cooling. There is no fire risk with immersion-style water cooling. A deionizer is necessary to continuously remove ions from the water in order to keep it non-conductive, but the equipment requirements are still quite high.

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

The disadvantages of oil-cooling include a high risk of fire prevention and a high cost of water-cooling.

ANC Active Noise Canceller

For the noise reduction of miners, the ANC active noise reduction technology is a bit excessive. The idea behind this is to surround the miners with 16 microphones to capture any noise they make. Through single-chip computer filtering, the waveform opposite the noise is calculated to cancel the noise. The ANC active noise reducer currently has more serious flaws. The separation between each device must be greater than 1.5 meters. Otherwise, they will have an impact on one another. Inconceivable levels of complexity have been attained in 16-channel acquisition, computation, and energy conversion. This technology will produce more significant results if it is applied to noisier situations.

Advantages: noticeable noise reduction effect;

Large area and expensive 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 keep the processor cool while minimizing noise is provided by the cargo volume. For mining cryptocurrencies in populated areas, use this product. This product, which has a high heat dissipation efficiency and low noise, only requires that the miner’s original fan be removed in order to be used.

The miners are silent, which effectively stops large fans like the Antminer from operating.

Antminer Silencer

The Antminer Silencer uses only pure copper wire, which has a number of 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—with high speed being the most common. When connecting, kindly observe 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 is appropriate for the majority of T17 series, Innosilicon series, Avalon 1066, and other integrated miners; input voltage: 220V; motor power consumption: 150W.

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

What Causes Mine Noise?

Bitcoin mining uses computers to perform complex mathematical equations to earn more coins. Additionally, as is common knowledge, computers require fans to keep cool.

In a bitcoin mining facility, thousands of computers mean thousands of fans, all of which are constantly spinning.

“I get four hours of sleep, maybe, because of that constant noise,” says Elizabeth Lundy, a Niagara Falls resident who lives about two blocks from the US Bitcoin facility.

“Even with the storm windows closed, I can hear the noise.”

The commotion can be clearly heard from Elizabeth’s front porch. As you get closer to the Buffalo Avenue plant, the noise only gets louder.

Another local, who lives more than 1.5 kilometers away from the plant, likens the noise to that of a 747 jet. Once, he could hear the sound of Niagara Falls – over 3km away – from his back garden, but now it’s just the whirring sound of the Bitcoin plant.

What is Antminer D7?

The Antminer D7 is a X11 algorithm ASIC miner produced by Bitmain. The power consumption is 3148W, and the output is 1286GH/s. The market’s strongest and most effective X11 miner right now is this particular model. The same algorithm can be used to mine any cryptocurrency, including Onix (ONX) and Dash (DASH).

Conclusion: Ways to Reduce the Noise of Bitmain Antminer D7

Even though the Bitmain Antminer D7 will make you a lot of money, mining at home or in the office can be extremely noisy when the machine is in use. Sound levels from a single Bitmain Antminer D7 range from 70 to 90 decibels (dB).
