**Repair of Fan Bearing Wear**
The noise from the fan inside the computer case is getting louder and louder. This is usually caused by a lack of lubrication in the graphics card fan's bearing, which leads to wear on the bearing hole. As a result, the gap between the fan shaft and the bearing becomes too large, and the axial clearance increases. The fan blade can move back and forth by several millimeters, causing the fan to move axially during rotation. This movement also causes the blade plane to wobble, leading to increased wear and more noise over time.
Most fan issues are due to this kind of bearing wear. Although replacing the fan with a new one is the most straightforward solution, it might not always be the best option for DIY enthusiasts. In some cases, finding an exact replacement can be difficult. However, this type of faulty fan is not beyond repair. I’ll now explain a simple and effective method to fix it.
All you need is a small piece of aluminum from a can and a little bit of clean butter (free of impurities). Here’s how to do it:
1. First, clean the dust off the fan to prevent any particles from entering the bearing during the process.
2. Remove the self-adhesive seal on the bearing and take off the bayonet on the shaft.
3. Clean out any remaining oil in the bearing using a soft cloth or tissue, then wipe the shaft thoroughly.
4. Apply a small amount of butter into the bearing. Be careful not to use too much, as it could affect the fan’s speed.
5. Cut a small piece of aluminum from the can. Make sure the outer diameter matches the bearing pin, and drill a small hole in the center that fits the shaft perfectly. Place this piece between the bearing and the bayonet to reduce the axial and radial movement. If the gap is large, add more layers to the pad so that the bearing movement is less than 0.5mm.
6. Reinstall the oil seal, add a little more butter, and put everything back together. Tighten all screws and nuts securely.
After reassembling, connect the power and test the fan. You should notice a significant reduction in noise. With proper care, this repair can last for at least two years. However, keep in mind that the precision of the repair may slightly reduce the fan’s speed.
This method is cost-effective and easy to perform, making it a great alternative to buying a new fan. It’s especially useful for those who want to extend the life of their hardware without spending extra money.

Commercial And Household Glass
There are differences in commercial glass and home glass in multiple aspects:
1. Use
Commercial glass:
-It is mainly used for commercial buildings, such as office buildings, shopping malls, hotels, etc. Its functions often need to meet the specific needs of public spaces. For example, the glass window of large shopping malls requires good display effects and attract customers' attention.
-In some commercial places, such as banks, jewelry shops, etc., glass may need higher security, such as bulletproof and anti -theft.
Home Glass:
-In for family houses, such as windows, doors, furniture, etc. Pay more attention to meeting the needs of family life, such as providing lighting, protecting privacy, and decorating home furnishings. For example, the window glass of the bedroom may choose to have a shading function to ensure sleep quality.
2. Performance requirements
Commercial glass:
-The intensity requirements are high, and can withstand greater traffic and possible external forces. For example, the glass curtain wall of a commercial building needs to withstand the test of natural factors such as wind and rain, wind pressure.
-The optical performance may require higher transparency and uniformity to ensure the brightness and beauty of the business space.
-An sound insulation performance is also very important, especially in hotels, conference rooms and other places, need to reduce interference of external noise.
Home Glass:
-A safety is the key, especially for families with children and the elderly. Safe glass such as tempered glass may be selected to prevent serious damage to people when crushing.
-The insulation performance is also important, which can effectively reduce the energy consumption of the family. For example, double -layer hollow glass can play a better thermal insulation effect.
3. Design characteristics
Commercial glass:
-In large size, to meet the needs of large -scale lighting and open vision of commercial buildings. The design pays more attention to the coordination with the overall style of the building, reflecting the sense of modernity and fashion.
-It special coating technology, such as low -radiation coating glass to reduce energy consumption and ultraviolet radiation.
Home Glass:
-The design is more diverse, and you can choose different colors, patterns and textures according to the family decoration style. For example, art glass can add an artistic atmosphere to home.
-If attention to details and humanized design, such as easy cleaning, convenient installation, etc.
