The fan of the miner is out of operation
the second method is: if the fan has a shaft core which can be oiled, it can be removed, the st on it can be cleaned thoroughly, and then a proper amount of engine oil can be dropped into the shaft core of the fan, so that the fan can operate normally after operation.

what is the specific model of the graphics card? If the graphics card supports the intelligent temperature control start stop technology, the temperature will not turn until it reaches 50-60 degrees
-
you can use gpu-z to detect the real-time temperature of the graphics card and see how much the temperature will turn. If the temperature reaches 50-60 degrees, it is normal
1. If the motor is used for a long time, the internal resistance of the motor will also be increased, and the load capacity will be reced, resulting in the failure to drive the wind blade to rotate
solution: replace the motor or replace an electric fan
2, too large axial clearance of motor shaft will also cause the load cannot be dragged
solution: also need to replace the motor, or find a professional to repair
3. If the electric fan doesn't work, the priority is that the motor can't be lubricated. When the fan blade is installed on it and the motor can't be dragged, it will be found that the rotating shaft can still work normally after it is removed, which means that the fan motor is not broken
solution: put some lubricating oil on the motor

precautions for fans:
1. Three core plug and socket with safety grounding wire must be used for desktop and floor type electric fans; The ceiling fan should be installed at a higher position of the ceiling, and the grounding wire may not be installed
The blade of the electric fan is an important part. No matter when it is installed, disassembled, scrubbed or used, the protection must be strengthened to prevent deformation3. When operating various function switches, buttons and knobs, the action should not be too fierce or too fast, and two buttons should not be pressed at the same time
4. The speed control knob of ceiling fan should be rotated slowly and orderly, not in the position between gears, otherwise it is easy to make the ceiling fan heat and burn
If the computer can't be turned on, the fan will stop once it rotates. Possible reasons:
-
check whether the CPU and heat sink have moved, the CPU is overheated, and the main board detects that the CPU is overheated and shut down protectively
-
if the speed of CPU cooling fan is low, the CPU will overheat, and the mainboard will detect the CPU overheating and shut down the CPU protectively
-
check whether the power connector is loose, whether the fast fuse in the power supply is broken or the power line is open
-
there is a short circuit on the motherboard or the machine, which causes the power supply or motherboard protection circuit to work
-
the motherboard is faulty or the power supply is in poor contact with the motherboard connector
-
the BIOS settings of the motherboard have changed
< / OL >
solution:
turn off the power immediately, carefully check and remove all kinds of faults, restore the factory settings of the motherboard, remove all cards and peripherals (hard disk, optical drive, etc.) to the minimum system to see if it can reliably start into the BIOS interface of the motherboard
What are the reasons for the excessive sound of the computer fan:1. The notebook itself has hardware protection measures. When the system temperature reaches a certain height, especially when the CPU temperature is high, the notebook will increase the speed of the exhaust fan and start to dissipate a lot of heat. Some notebooks will not rotate when the workload is low, Only when the system temperature is too high can the exhaust fan be started to dissipate heat. In this case, it is concive to the stability and safety of the machine, so it is not in the scope of discussion
1. Unplug the power supply and prepare cleaning tools; Open the case with a screwdriver and clean the fan; It's easy to pull up the fan for cleaning. After cleaning, install it. Rebooting (generally useless, but try to do all the simple operations)
extended data:
the main performance of the fan is reflected in the following aspects: speed, blade shape, blade
CPU, fan
angle and bearing system. In general, the fan speed is indicated in the radiator manual. Generally speaking, 30% of the heat dissipation effect of the radiator depends on the speed of the fan
But the higher the fan speed, the better. The correct fan speed should be determined according to the heating capacity of CPU. The selection of fan speed of different specifications should be differentiated. The basic principle is: under the premise of procing the same air volume, the higher the fan speed, the lower the noise. Generally speaking, the speed between 3500 rpm and 5200 rpm is more conventional The larger the power is, the stronger the wind power is and the better the cooling effect is. The power of the fan is directly related to the speed of the fan, that is to say, the higher the speed of the fan, the stronger the fan. At present, the fans on the general computer market are 12V DC, and the power varies from 0. XW to 2. XW, so the size of power needs to be selected according to your CPU heating capacity In particular, we should not emphasize high power unilaterally, just match the power of CPU itself. If the power is too large, not only the cooling effect will not be greatly enhanced, but it may increase the workload of the computer and eventually shorten the life of CPU and fan. Therefore, when choosing the power of CPU, we should measure the heat. And the front opening of the fan should always be kept clean to avoid blockingbetter radiator, no burr on the edge, no deformation on the fin, smooth bottom, no crack, neat appearance, elegant shape, quality assurance, trademark with anti-counterfeiting mark or other features, etc
in addition, when choosing the radiator, you should also pay attention to that the bottom of the radiator should not be too thick, because the thermal conctivity of aluminum is not very good, too thick will affect the heat transfer; In addition, the guide groove on the surface of the radiator should be more dense, so as to ensure that the radiator can have a larger contact area with the air, so as to enhance the heat dissipation effect
generally, if the economy permits, the computer enthusiasts will transfer the water cooling fan to the CPU to achieve the effect of rapid cooling through liquid circulation
1. Press the case key on the keyboard. When the light is on, it means that the display card, monitor and other hardware are in trouble
2. If the keyboard light doesn't light up, it means that there is a problem with memory, CPU, motherboard or power supply
solution:
1. If the keyboard light doesn't work, first wipe the memory mole with an eraser, and check whether the golden finger of the memory mole has burnt marks. Replace the memory slot
2. Check the capacitance and resistance on the motherboard to see if the capacitance is bulging and if there is scorching smell on the motherboard, and clean the st on the motherboard
3. Remove the CPU fan, power it on, and manually test whether the CPU has temperature change. If not, the CPU is not working. Either the main board is broken or the CPU is not plugged in, plug the CPU again
4. Power supply problem. Although the power supply is powered on, it can't make the main board work normally. Replace the power supply and try
5. If the display card is loose or oxidized, the keyboard light will be on and the screen will not be displayed. Wipe off the gold finger of the graphics card with an eraser and check whether the capacitance on the graphics card is bulging
6. Minimize the test method, leaving only the power supply, motherboard, CPU, memory, graphics card, keyboard and display. Unplug all the wires on the other motherboards, and use a screwdriver to short the switch pins. If it is normal, add the remaining hardware one by one until the cause of the problem is found out
tip: turn off the power for all operations. If you are not familiar with computer hardware, it is recommended to find professional maintenance personnel.
lock
light on the keyboard is on) and then check whether there is too much st. Clean the st and check whether the connecting line behind the memory gold finger (that is, the copper sheet) is inserted wrong with the eraser. The possibility of hardware damage is very small (after all, it's not made of tofu). Press the CPU fan (sometimes the CPU base soldering will often lead to failure to boot, and then somehow it's better)
