Course Introduction:1. Installation of computer exhaust fan? The computer exhaust fan is generally installed at the rear of the host case. Use four screws to fix the fan to the rear panel of the host, and then plug it in. 2. Does the computer exhaust fan sound? Computer exhaust fans always make some noise, because the exhaust fan has a relatively large power to work, and it takes some effort to blow the fan. 3. Computer exhaust fan: Principle, installation and maintenance Principle of computer exhaust fan In the computer, the exhaust fan is one of the important components for heat dissipation. The work of the computer will generate a lot of heat. If the heat cannot be dissipated in time, the performance and life of the computer will be affected. Exhaust fans use wind power to remove heat by rotating blades. Exhaust fans are generally divided into two types: mechanical

Course Introduction:Is it normal for the graphics card fan to buzz loudly? (Solution to the loud noise of the cooling fan) The fan has adhered to dust, causing the wind resistance coefficient of the fan blades to increase, and the noise during operation will also be louder. You can clean and sweep away the dust on the fan blades, which usually solves the problem. The fan bearing lacks lubrication and the friction coefficient increases. You can add a drop of sewing machine oil to the bearing to increase lubrication. Adjust the speed. First, use a brush to clean the dust on the fan to prevent dust from entering the bearings. Dust is the biggest killer of graphics card fans. It is recommended to clean the computer once every 36 months to prevent computer failure due to dust. Caused by too much dust in the chassis: Increased load will cause the fan speed to increase. If there is a lot of dust, the noise will be more obvious. It is recommended to carry out dust removal work. It should be noted that care must be taken to prevent collision.

Course Introduction:How to turn on the motherboard fan? Turn it on with the knob on the left! ! ! ! How to connect the motherboard fan? Answer: The method is as follows: 01. Fan and motherboard. Pay attention to the fan and apply thermal paste. 02. Grasp the 2 buckles of the fan with your left and right hands. 03. Place the fan above the motherboard CPU, and snap the left buckle into the motherboard holder with your left hand. 04. Press the right buckle with your right hand to lock it into the right card holder. 05. Finally, try lightly to see if both sides are stuck and it is stable. 06. After confirming that the card is stable, slowly raise your hands, and the installation is complete! The motherboard fan is spinning but making a squeaking sound? Generally speaking, when this happens, there are usually the following situations: 1. Lubricating bearings. The most important component of fan rotation is the bearing. If there is a lack of lubricating oil over time, noise will be generated when rotating at high speed. therefore, we

Course Introduction:1. Computer fan speed adjustment guide: How to correctly adjust the computer fan speed. Is your computer fan speed too high or too low? Don’t worry, correct fan speed adjustment can help you optimize your computer’s cooling effect, improve performance, and extend the life of your hardware. This article will explain how to correctly adjust computer fan speed to keep your computer cool and quiet. Why should you adjust computer fan speed? The computer's fan speed adjustment can effectively control the rotation speed of the cooling fan, thereby affecting the cooling effect. When the computer is running under high load, appropriately increasing the fan speed can reduce the hardware temperature and improve performance stability; while under low load conditions, lowering the fan speed can reduce noise and extend the fan service life. Adjustment method There are two ways to adjust the computer fan speed, one is through BIO

Course Introduction:The disassembly and assembly operation of the electric fan can be carried out according to the actual maintenance needs. Let's take the Midea FTS35-M2 electric fan as an example to introduce the disassembly and assembly method of the electric fan. 1. Disassembly of the electric fan grille and fan blades The electric fan grille and fan blades are important components on the top of the electric fan. If you suspect that the fan blades are faulty, you need to remove the grille first and then the fan blades. The grille and blades of an electric fan are usually fixed with screws. When disassembling, find the screws on the grille, unscrew and remove the grille, and further disassemble the fan blades. Remove the electric fan grille and fan blades. The specific operation is as shown in the figure: 2. Removal of the electric fan motor casing. The electric fan motor is fixed in the electric fan casing by fixing screws. When it is suspected that the motor in the electric fan is faulty, The casing of the motor should be disassembled first.
