Where Does Miner Noise Originate From?

ASIC devices typically have two fans. One of these fans draws air in, and the other expels the hot air generated by the ASIC chips, preventing damage from high temperatures. These fans must rotate at a specific speed to expel the hot air, which is the reason for their considerable noise.

For example, the Antminer S9 has fan speeds ranging from approximately 4,320 to 4,560 RPM, generating a noise level of around 76 decibels (dB). This is comparable to the noise inside a busy train station or passenger terminal.

Best Solutions for Reducing Miner Noise

Now, let’s move on to the solutions. There are various tricks to reduce the noise from mining devices. In this section, we will explore five of the best methods for minimizing miner noise:

Reducing Noise at the Source by Lowering Ambient Temperature
Reducing Sound Perceived by the Human Ear
Using Mining Boxes
Using Soundproof Curtains or Foams
Using a Dedicated Room

1. Reducing Noise at the Source by Lowering Ambient Temperature

Most ASIC devices, especially newer models, automatically adjust their fan speed based on the ambient temperature. Therefore, if an ASIC is placed in an environment with a lower temperature (or the ambient temperature is lowered), the fan speed will automatically decrease, leading to a reduction in noise. So, by choosing a cooler environment or lowering the room temperature, the fan noise can be reduced.

There are many methods for controlling the temperature of a room or farm, which are beyond the scope of this article. The best approach is to seek assistance from specialists in designing a suitable and efficient ventilation system.

2. Reducing Sound Perceived by the Human Ear

One method that might not be pleasant for many is using noise-canceling headphones or earplugs while sleeping or working in the vicinity of miner operations. This approach can make working and living around ASIC installations somewhat more bearable. However, the drawback is that it only reduces the sound for the individual using these tools and has no effect on others.

3. Using Mining Boxes

A mining box is a container lined with a high-quality sound-insulating foam layer, with precisely integrated fan outlets. It is advisable to use only high-quality, proven mining boxes. Ensure that the pipe opening (usually galvanized) connected to the fan outlet is larger than the fan itself and is properly sealed.

For further noise reduction, the inside of the pipe can be lined with fire-resistant sound-insulating foam. The density of the insulation is also important; a higher density will transfer less sound to the outside.

Using pipes is recommended to easily transfer hot air out of the box, alleviating concerns about the internal temperature. Note that correctly installing the pipe opening onto the fan outlet is a critical task and should always be performed by a skilled and experienced individual.

While a mining box can be assembled at home with a few pieces of wood, this should only be attempted if you possess sufficient technical knowledge, skill, and experience. A minor error in the quality of materials used or the insulation of the box can rapidly increase the internal temperature, potentially damaging your miner or even leading to a fire.

A quick search on YouTube will reveal that many people use large, high-quality plastic coolers to build mining boxes, which is not a bad idea. However, enclosing an ASIC device in a non-standard box carries its own risks, and there’s no guarantee this method will yield satisfactory results.

4. Using Soundproof Curtains or Foams

Installing a thick curtain, using acoustic foams, or sound insulation (fire-resistant models) on walls can reduce noise to some extent. In this method, care must be taken to ensure that heat can easily transfer out of the room, as otherwise, due to the flammability of these materials, there’s a risk of fire.

5. Using a Dedicated Room

The final solution for reducing miner noise is to use a dedicated room. For a large number of miners, a special room (or a portable cabin) can be designated and customized. It’s preferable for the room to have two windows to facilitate adequate ventilation with exhaust fans. Separating the miners using gypsum boards can significantly help reduce their noise. The fans should be connected to the end of the pipes attached to the miner’s two output and input fans.

Common Mistakes in Reducing Miner Noise

While some methods are effective in reducing miner noise, they can cause irreparable damage to your devices. In this section, we will review the most common mistakes.

Do Not Use Mineral Oil

Submerging an ASIC device in mineral oil might help reduce its temperature or noise, but it is not recommended. Making modifications not approved by the manufacturer can damage internal components and void the warranty.

Nowadays, many computers use this method instead of fans, but its use in mining hardware is not yet widespread. The vast majority of ASIC device owners (with a few exceptions like the S9 Hydro) have not embraced this method.

Using mineral oil requires additional equipment such as an aquarium and a radiator, and the radiator itself produces a lot of noise. This oil is primarily used for cooling rather than noise reduction. Also, remember that according to experts, if you place a miner in mineral oil, you cannot use it outside of oil afterward.

Miners in mineral oil

Generally, using mineral oil is not only expensive but also a highly specialized task. Incorrect execution can lead to device failure. Furthermore, purchasing the oil must be done carefully. Most oils available in Iran are of very low quality, and some unscrupulous sellers exploit buyers’ inexperience by selling motor oil or similar products labeled as mineral oil, which can quickly damage the hash board and other components.

Do Not Remove or Tamper with Fans

As we mentioned, the root of the miner’s loud noise is its fan. However, you should not remove or tamper with them. Antminer ASICs and those from most manufacturers automatically adjust fan speeds. If the ambient temperature is low, the fan speed will automatically decrease to a level where the device can operate with the least amount of noise at that temperature.

By reducing fan speed through software or by replacing the original fans with lower-speed ones, you risk encountering problems controlling the miner’s temperature, potentially damaging its components and chips.

Do Not Place Devices in Open Areas

The final mistake to avoid when trying to reduce the bothersome noise of a miner is placing it in an open area. This exposes the device to a significant amount of dust, reducing its lifespan. Moreover, if the air humidity is high or it rains, your device will suffer severe damage.

Frequently Asked Questions

What are the best methods for reducing miner noise?

Using a mining box, soundproofing a room, lowering the ambient temperature, and placing the miner in a dedicated room are the best methods for reducing miner noise.

Are mining boxes (soundproof boxes) suitable for all devices?

Yes, mining boxes are a general and effective solution for noise reduction. However, the critical point when using them is to ensure adequate ventilation and air circulation. If the box is not designed correctly, it might increase the device’s temperature and reduce its lifespan.

Does lowering the ambient temperature affect miner noise reduction?

Yes, it has a direct impact. Cooler air helps the device manage its temperature more easily. Consequently, the cooling system (fans) does not need to operate at maximum speed, leading to a significant reduction in noise.

Conclusion

The loud noise of miner devices is unavoidable due to the operation of fans that cool their powerful chips. To control this noise, the most effective methods include using standard sound-insulating mining boxes, placing the device in a separate, soundproofed room, and lowering the ambient temperature. These measures allow the fans to operate at lower speeds, consequently producing less noise.

Finally, we recommend avoiding non-standard and risky methods such as submerging the device in mineral oil or tampering with and replacing the main fans, as these actions can cause serious damage to the miner. The best approach is a combination of safe solutions like proper ventilation and environmental insulation to preserve the device’s health and ensure your peace.
