Mining fan

1. No matter what kind of computer, noise is basically a fan problem. If you can't clean up the st on the fan, replace it

2. Use your brain to know that the fan can't mine... Graphics card has powerful parallel computing power, which is much more efficient than CPU when it is used to mine. In the past, many people used to mine with graphics card, resulting in the high price of a card. But now, bitcoin is collapsing. No one is digging. In the later stage, people didn't have to dig with graphics cards. They used specially designed circuits and quick miners. They couldn't even earn their electricity bills.

4. The fan on the excavator is of average quality, especially noisy. I used to replace it with a Japanese yamayo fan. The effect is very good, and the sound is much lower. I have been using it now.

5.

mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

6. Mining machine and computer are not the same, and mining machine because of long-term high load operation, internal aging will be serious.

7. (1) The PCB of the circuit board has tin spot empty soldering or tin spot cracking. This is usually caused by intense vibration, focusing on the detection of transformers, power tubes, rectifier diodes and so on. I repaired one of them, but the rectifier diode tin point cracked. Therefore, the voltage can be measured when the load is no-load, but the current will increase when the load is on. Due to the large contact resistance, the voltage will be pulled down and will not work 2) There is always a problem with the fan or the over-current protection circuit. Move the fan blade by hand to see if the friction is great. If it's too big, it means that the fan can't work and needs to be replaced. Otherwise, the switching power supply will proce over-current protection e to excessive input current without voltage output 3) Of course, do not rule out your other hardware is not faulty. It's better to first disconnect all the loads of the power supply (especially the main board), then short the starting line of the power supply to see if the power supply can work (if there is voltage output, the power supply fan will turn), if it can work, then connect the loads one by one until the fault point is found. Good luck! I can't change it or look for the information of this model on the hard city
