Computer fan noise is too big what to do

1, remove the fan from the chassis, you will find a sticker sticker on the back

2, use tweezers to take down the post. Some fans have stickers on both sides, I do not know which side is the sealing effect, then the two sides are open to see it.

3, uncovered after the bearing is found in which, carefully again see, will find a small stop ring. Many friends may be in this step, they will be injected into the fan lubricating oil. This often does not play any role, the small block ring to seal the role, the lubricant basically not much can go in, and the lubricant volatilization quickly.

4. Use tweezers carefully to remove the retaining ring, do not use brute force.

5, these steps is to remove the dust on the fan blade clean, conditional recommended vacuum cleaner and small brush cleaning.

6, lubricating oil belongs to liquid lubricating products, liquidity is strong, volatile easily. The lubricant can be firmly in the bearing on the production of a lubrication ring, not easily volatile, can be a lasting lubrication effect, effectively reduce fan noise.

7, let the bearing indicate full contact lubricant, achieve the lubrication evenly.

8, open the self-adhesive and then stick up, it will not be too sealed. So we re-get a stick, can effectively achieve airtight purposes, reduce evaporation.

9, the fan installed on the host, and then try again. The noise reduced a lot and the world was finally quiet. Some fans may not have a small stop ring, then it is very convenient to disassemble. However, it is important to inject lubricant or lubricant into the bearing and the copper ring, and finally put the sticker on it. This allows for long-lasting lubrication purposes.
