Good sleep is also necessary for mining - a practical guide to noise prevention for mining machines

In 2001, the Global Sleep and Health Program, sponsored by the International Mental Health and Neuroscience Foundation, launched a global campaign to draw people's attention to the importance and quality of sleep. In 2003, the Chinese Sleep Research Society officially introduced "World Sleep Day" to China. The theme of World Sleep Day in 2018 is: Regular work and rest, healthy sleep.

There are many factors that affect sleep, one of which is:

noise.

Ant Girl secretly observed that noise reduction has become a major concern for the majority of miners. Noise not only affects sleep, but also affects physical and mental health, neighborhood harmony, and family harmony... But the mines still need to be mined and money needs to be made. How can we mine and make money at the same time? Today, Ant Academy will talk to you about noise reduction.

Usually, an Antminer ASIC miner contains two fans, one at the air inlet and one at the air outlet. The function of the fan is to dissipate the heat generated by the chip when the miner is operating, so as to prevent the miner from being damaged by high temperature. In order to effectively dissipate heat, the miner fan must reach a certain speed, which is the source of noise.

Take the Antminer S9 as an example. When the machine is running normally, the fan speed is between 4320-4560 rpm, and the noise level is about 76dB ( A ) at 1 meter away from the mining machine. This is roughly equivalent to a busy transportation hub.

Judging from the decibel level, the noise generated by a mining machine seems to be within an acceptable range. But who among the miners today doesn’t have several machines? Besides, mining machines are running 24/7 . Even if you can pretend that you can’t hear anything, your neighbors will probably have some complaints.

Thus, the great working people opened up their wisdom.

cannot.

Without a fan, the high temperature generated by the mining chip during the calculation process cannot be dissipated, which will cause irreversible damage to the mining machine. In addition, if the mining machine does not detect the fan running, the mining machine will not work.

cannot.

Antminer has the function of automatically adjusting the fan speed. When the surrounding temperature is low, the fan will automatically reduce speed, so that the miner can operate in the most suitable temperature environment. At this time, the noise decibel of the miner will indeed be reduced. However, if the fan is forced to reduce speed (such as replacing another low-speed fan), the high temperature cannot be dissipated in time, which will have an adverse effect on the operation of the miner.

It’s best not to.

If miners modify the mining machine, it is very easy to damage the precision parts inside the machine, and unauthorized modification will also make the machine lose its warranty. Indeed, many computer hosts have replaced traditional fan cooling with water cooling/oil cooling devices, which seems to provide a new idea for cooling the mining machine. However, looking at all the mining machines on the market, none of them use water cooling/oil cooling. The reason behind this is most likely that the technology does not meet the standards. Therefore, it is recommended that miners do not try it easily.

In theory, there are three ways to reduce noise:

Reduce noise at the source.

As mentioned above, the fan of the mining machine will automatically adjust the speed. Therefore, if the mining machine is running in a low temperature environment, the fan speed can be reduced to a certain extent, thereby reducing noise. Therefore, miners can choose to place the mining machine in a ventilated and cool place.

Reduce noise during sound propagation.

Many miners will install sound insulation panels, sound-absorbing cotton and other devices indoors. In addition, some miners will equip their mining machines with sound insulation boxes. These methods are mostly used by miners who mine at home. It should be reminded that while pursuing sound insulation effects, do not forget to control the indoor temperature.

Attenuates noise at the human ear.

When sleeping, wearing earplugs or earmuffs are both good choices.
