In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120
A practical guide to noise reduction for miners
Noise reduction and noise reduction have become major concerns of most miners. Noise not only affects sleep, but also affects physical and mental health, neighborhood harmony, and family harmony. So how do mining and make money? Today I will talk to you about noise reduction.
Where does miner noise come from?
Usually, an ASIC Antminer contains two cooling fans, one at the air inlet and the other at the air outlet, and some miners even have 4 cooling fans. The function of the fan is to dissipate the heat generated by the chip in time when the miner operates so that the miner can avoid damage caused by high temperature. To effectively dissipate heat, the miner fan must reach a certain speed, which is the noise source.
Taking the Antminer S9 as an example, when the miner runs normally, the fan speed in the background is between 4320-4560 rpm, and the miner measured about 76dB(A) at 1 meter. Roughly equivalent to a busy transportation hub.
Noise reduction methods adopted by miners
In terms of decibels, the noise produced by a miner seems to be within an acceptable range. But today's miners don't have several machines in their hands. Besides, the miners are running 24/7. So even if you can pretend you can't hear anything, the neighbors will probably have opinions. As a result, the great working people opened their wisdom.
Miner A: Since the miner's noise is generated by the fan, let's remove the fan.
Answer: This method is not feasible. If there is no fan, the high temperature generated by the miner's chip during the calculation process cannot be dissipated, which will cause irreversible damage to the miner. Also, if the miner does not detect that the fan is running, the miner will not work.
Miner B: Can you forcefully reduce the fan speed to reduce noise?
Answer: No. Antminer has the function of automatically adjusting the fan speed. Therefore, when the ambient temperature is low, the fan will automatically slow down so that the miners can run in the most suitable temperature environment, and the noise decibels of the miners will indeed be reduced. However, if the fan is forced to slow down (such as by replacing another low-speed fan), the high temperature cannot be dissipated in time, which will adversely affect the operation of the miners.
Miner C: I heard that water and oil cooling could also cool down, so that I will modify the miner myself.
Answer: Best not to. If a miner modifies a miner, it is very easy to damage the precision parts inside the machine, and unauthorized modification will also make the machine lose the warranty qualification. It is recommended that miners do not try it lightly.
How to scientifically reduce noise for miners?
In theory, there are 3 ways to reduce noise:
1) Attenuate the noise at the sound source
The miner fan will automatically adjust the speed. Therefore, if the miner operates in a cooler environment, the fan speed can be reduced to a certain extent, reducing the noise. Therefore, miners can choose a ventilated and cool place to place miners.
2) Attenuate noise during sound propagation
Many miners will install sound-insulating panels, sound-absorbing cotton, and other devices indoors. In addition, some miners will equip their miners with miner mute machines. These methods are used mainly by some miners who mine at home. However, it should be reminded that while pursuing the sound insulation effect, do not forget to control the indoor temperature.
3) Attenuate noise in the human ear
When sleeping, wearing earplugs and earmuffs is a good choice.
