Handling of common problems:
With more and more integrated circuit in the microprocessor, and the energy consumption continues to increase, the heat problem must be revisited again. For the computer's cooling system, we most commonly use air cooling and it is also the radiator fan. The main use of the cooling fan has two devices, one is the power and the other is CPU in the desktop. Power supply fan generally longer life because of design problems, and CPU cooling fan is easily-consumed products. This paper is aimed at the common faults of CPU cooling fan and puts forward some simple solutions.
The first common failure: the CPU cooling fan suddenly issued a very noisy noise in the near future. This noise is even bigger than the chassis power sound, after careful examination, because it has long been lost "repair", fan surface and radiator surface cracks are gathering dust very much. Fan motor lubricating oil has completely dried up, so this situation caused the motor roar .
solution：
The fan and the radiator are separated at first. Secondly the radiator can be cleaned directly by running water. Heat fan first wipe with a soft paper, the gap can be used for medical small cotton swab. Open the plastic sticker on the back of the fan, and use the common sewing machine oil to drop 2 drops to 1 drop to the module. The paste of the toy car grease can also be used in this condition, but dosage should not be too much.
The second common failure: the early use of cooling fan is normal. But it can be suddenly find that the fan automatically removed from the fixed position for a period of time. After investigated, we can find that the original fixed fastener has failed due to radiator fan rotation caused by the resonance phenomenon. It causes the fan position to move.
Solution: replace a new clip.
The third common failure: a new CPU cooling fan appears the phenomenon of noise is too large and poor rotation in the use of not more than a week. Fan speed is relatively slow and the noise is relatively large in the just boot, over a period of time it returns to the normal state. At first we thought that it is a problem with fan motors, but in the replacement of the same fan, it is still appears the above phenomenon after the use of a period of time. After analysis, we find the original cooling fan is located in the indoor temperature is relatively low, which caused the failure of the lubricating oil on the rotating bearing.
Solution: applying anti - Anti - oil to the fan and pay attention to the temperature of the environment used.
