Collection of practical methods for noise reduction and temperature reduction for miners

Collection of practical methods for noise reduction and temperature reduction for miners I believe that all friends who buy miners and mine at home have encountered a problem, noise; the noise generated by graphics card miners is not too big, and the noise generated by professional miners can reach more than 80 decibels, including Ebit E9, Antminer S9 , A3, D3, etc. Most miners use 12CM violent fans  for heat dissipation, and the fan speed can reach more than 6000 rpm. The fan blades' rapid cutting of the air produces a great noise. Take the Antminer S9 as an example: the noise can reach 95 decibels when the ambient temperature is greater than 25 degrees. In the silent night, the miners' noise can be clearly heard from 300 meters away without being blocked, and it can also be transmitted to the neighbors' ears when the door is closed in the room. To reduce the miners' noise, the vast number of miners have exerted their superhuman wisdom and produced a variety of noise r

How to choose a miner to get the most profit?

How to choose a miner to get the most profit? The first thing a miner friend mines is how to choose the right miner rig. This involves several issues: When to buy miners, what price, and what type of miners. When to buy miners Bitcoin has an apparent bull-bear cycle. Buying miners is like buying coins. The timing of entry is essential. Miners' prices are often inflated when buying miners at the bull market's top. For example, the Antminer S9 was even sold at the end of 2017. Around $4,800. At this time, once you encounter a slump in the bear market, the payback will be indefinite. But if you buy miners when the bears are turning bulls, you can not only buy cheap miners, even miners whose cost prices have fallen below the cost. When the currency price rises in the subsequent bull market, the miners' income increases sharply, the payback time will be rapidly shortened, and the miner rigs' price will also increase. The price of Antminer S9  plummeted with the big bear mark

How to choose a suitable miner power supply?

How to choose a suitable miner power supply? The choice of miners' power supply is significant to the operation of Bitcoin miners. In mining, the miner's power supply is the critical treasure to ensure the smooth operation of Bitcoin miners. Miner power consumption is the primary indicator of power supply selection. Each miner manufacturer indicates the power consumption of the miner. The specific power consumption of the miners in the mining factory is usually higher than the official power consumption. Therefore, in the case of selecting a power supply, it is best to ask how much power the miner of this model should be equipped with. The wide range of power supply applications for miners now means that the technology and equipment have improved significantly. After the improvement, the miners are much better at artistry and processing. With the continuous changes of the current era, the use of power supplies for miners Will become more and more refined management. We know tha

What to pay attention to when buying a miner power supply?

What to pay attention to when buying a miner power supply ? The price of Bitcoin is one price per day, so many people who believe in opportunities also want to make money through mining by ASIC miners .   S o let's understand what to pay attention to when buying a power supply for miners? 1. Before purchasing a power supply , first determine whether the local grid voltage meets the power requirements, whether the power supply output voltage and power specifications can meet the requirements of the supporting load products, and whether the power supply output terminal type, polarity, and quantity are consistent with the requirements of the supporting load. If you are not sure about the power consumption of the load product, it is recommended to measure it with an electronic load tester  in advance.   2 . Considering the differences in power plug standards in various countries, the standard power supply does not have an AC input cable. Therefore, it is recommended that customers purc
