The sound produced by the first sound wave of the cooling fan during operation is produced by the vibration of objects (solids, liquids and gases) when an object is spinning or vibrating back and forth. The surrounding air will be affected by it, so it will move back and forth. This motion is passed from one particle to another, alternating dense and sparse layers, so sound waves are excited in the air. At a certain distance, when a sound wave reaches people's ears, it creates the perception of sound.
If the cooling fan is used for a period of time, it will make a lot of noise, which is very annoying. Is there any way to eliminate or reduce noise? Here's how to eliminate the noise of the cooling fan.
Generally, there are two reasons for the noise of the cooling fan: excessive dust and dry oil. If not, it's a parts problem. Let's talk about how to operate it first.
1. Replace the silent fan: We can replace a cooling fan, we have many silent fans on the market now. The silent fans have passed strict tests, which can effectively reduce the noise of the power supply. Also, it can replace the better cooling fan for the power supply. The process of replacing the powered cooling fan is also very simple. The key is to pay attention to the connection between the fan and the power supply.
2. Clean the dust of the cooling fan: first prepare a small bottle of oil and a toothpick, then open the object case, take out the fan, find the dust collection position on the fan blade, and clean it with a soft brush. After cleaning is complete, the volume label usually appears in the middle of the front of the cooling fan. Open the tab to view the bearing of the fan. Use a toothpick to dip the lubricating oil on the bearing, paying attention to the right amount. When done, put the label back on to avoid dust, then restore the cooling fan and power supply. When refueling the fan, do not use engine oil arbitrarily. Poor-quality engine oil does not help lubricate, but will accelerate bearing wear. We should choose special products that may be replaced by high-quality sewing oils.
3. Buffer shockproof: If we take the power supply as an example, for the power supply, the shockproof position is not only the connection between the cooling fan and the power supply, but also the connection between the power supply and the chassis. In addition to being firmly fixed, you can also add buffer pads such as thin cloth and rubber pads to the contact parts to purchase special power shockproof products.
