A big computer noise solution

Sometimes when you use a computer, you may hear a buzzing sound from your computer, I believe many friends have encountered, especially those who are older or long time did not clean the computer, the noise is particularly large, sometimes this noise has seriously affected our use, then the computer noise should be how to solve it?

　1 fan blade "eccentric"

Normally, the center of gravity of the fan blade is on the axis, and it runs very smoothly and with very little noise. If the fan quality is not good, the fan's center of gravity does not cause "eccentric" on the axis, so that the fan rotation, the fan bearing gradually wear, make the vibration increased noise. If you are a gamer, the impact is even greater. Play the game when the CPU occupancy rate is high, if the hard disk speed, memory is small, then in the processing of a large number of game data, it is bound to greatly increase the CPU work pressure.

Solution: It is recommended to replace the high quality fan.

2, the CPU fan bearing oil shortage

The fan of the sliding bearing is used for a long time, and the lubricating oil inside is dry.

Solution: Add some lube to the fan. Here is the question of how to remove the fan and how to drop the lubricant.

The big four reasons of computer CPU fan sound and its solution

(1) How to remove the CPU fan

First remove the fan and connect the fan base, the fan is connected with the screw to the base, the base is to use the clamp to connect to the motherboard, the fan and the base after the demolition, is the CPU, it has a press bar next to, optimistic direction, will press the pole to lift, vertical CPU to take out on it. The entire CPU fan is removed.

(2) To pay attention to the problem of oil injection fan

A. Using sewing machine oil or oil, I suggest using four-stroke motorcycle oil, because the sewing machine oil is very thin, fluidity and volatility is strong, after the oil is not used for a long time, the fan will be "relapse", and the sewing machine oil on the shock buffering effect is very small, for the weakening of noise, the role is not, The oil just avoids the above two disadvantages.

B. Oil after the sealing problem, the fan oil spot affixed with a label paper, peeled off the label paper after the oil, the label paper generally can not be used, what to replace it? I use four or five layers of scotch tape. To find a roll of Scotch tape, with a knife crosswise uniform knife, cut about four or five layers, and then the four or five-layer of scotch tape with paper together can be used. Note that you must not only use a layer of tape paper, because a layer of tape in the fan rotation easy vibration generated noise, there may be damage caused by oil splash. Use Scotch tape paper instead of label paper there is an advantage is the fan is not oil, a look will know, at a glance, do not take apart.

　3, the fan speed is high

The reason for the new fan sound is that it is often caused by high speed of the fan, in particular, the original fan, the area of the fan blade is small, the number of cooling fins aluminum, so if the heat is large in order to ensure that the temperature of the processor is not too high, you must increase the speed of the radiator fan can be.

Solution: The first replacement of large fan blades, large fins area, the use of better heat conduction metal radiator, so that the fan speed will be very low, the noise will be very small. The second is to manually adjust the speed of the processor fan to adjust to a small noise fixed speed. Recommended reading: CPU fan speed adjustment methods and procedures (illustrated carefully)

4, dust accumulation too much

CPU fan for a long time, fan leaves will accumulate a lot of dust, if it is in the dusty and humid environment, the fan will form a layer of mud-like dirt. Dust accumulation will bring two major hidden dangers, the first is caused by the decline in rotational speed and affect the cooling effect, the second will make the fan rotation resistance increases, but also because of the fan's dynamic balance is reduced and makes a lot of noise.

Solution: is also the same as the fan oil, first remove the fan, the specific split method, and then you can use a small mini vacuum cleaner or hair dryer to clean the dust, pay attention not to dip water.

Note: Many computer motherboards turn on intelligent temperature control, in the CPU for a large number of calculations caused by high temperature fans will improve the speed, so the CPU to 100 when the fan will make a big noise, to the computer back to normal conditions will be small, this is normal phenomenon.
