The temperature rise (the difference between the actual temperature of the device and the ambient temperature is called the temperature rise) is less than 25 degrees Celsius, which has a great impact

The temperature rise (the difference between the actual temperature of the device and the ambient temperature is called the temperature rise) is less than 25 degrees Celsius, which has a great impact on the normal operation of the device. Especially when the temperature rise of network switches, routers, computer motherboard chips, network cards, etc. is large, the device will It will be unable to run; especially portable (also called notebook) computers, which have difficulty dissipating temperature rise due to the design priority of volume, and are most likely to have temperature rise problems that lead to crashes and restarts; the measures are as follows: 5.1: Place the device (referring to : Hubble, modem, router or network switch, computer, etc.) should be placed in a safe place for people. First disconnect the power, then open the cover of the device, and use air convection to enhance contact with the air for natural heat dissipation; 5.2: Give the device Install a micro fan to increase air convection and force heat dissipation; 5.3: If you are in IT, I suggest you: After disconnecting the power supply, install heat sinks on the heating components of the equipment. 5.4: After the device is disconnected from the power supply, use a 3mm drill bit to drill multiple holes up and down the device to enhance air convection and improve heat dissipation conditions; 5.5: Place the device in a ventilated and dry place, preferably a drill (also available on the market for laptops) ) insulation heat dissipation bracket to support the device for natural heat dissipation; 5.6: After the computer is used for a long time, when the silica gel between the CPU and the heat sink dries up, the CPU will seriously heat up, resulting in packet loss, delay, slowness, Repeated startup, disconnection, interruption, disconnection, automatic shutdown, crash, etc. Reapply silicone and resume normal use. C: Timely clear the garbage fragments and IE cache generated by surfing the Internet: As long as you use the computer, garbage will be generated. If you don't clean it up in time, it will accumulate more and more. If you don't clean it for a long time, the space of the running C drive will become smaller and more cluttered. , and finally gradually slows down until it crashes; therefore, regular cleaning and running of the C drive can maintain the computer's running speed. D: Let the ADSL device synchronize first: power off the device and then restart it. Six: Optimize the network structure. When people turn on the computer and surf the Internet, garbage will be generated. Just like eating, if they do not clear the table, wash the tableware, or clean the stove, computer garbage will be generated. The computer will gradually show symptoms of slowness, lag, delay, repeated startup, and disconnection. and other failures; therefore, I personally recommend using some small tools: such as Super Rabbit, Optimization Master, Master Lu or 360, etc.; develop a good habit of cleaning up garbage before going offline. 6.1: Clear the garbage fragments and IE cache generated by surfing the Internet in a timely manner: As long as you use the computer, garbage will be generated. If you don’t clean it up in time, it will accumulate more and more. If you don’t clean it for a long time, the running C drive space will become smaller and smaller and disorganized. , and finally gradually slows down until it crashes; therefore, regular cleaning and running of the C drive can maintain the computer's running speed. 6.2: Synchronize the ADSL device first: power off the device and then restart it. Seven: Software settings and configuration download software should be downloaded from large official websites as much as possible. Do not install 3, informal software, P2P (resource-consuming) software, and uncommon software. Turn off all unnecessary software. Network connection and startup items, such as Thunder BT Donkey, etc.; do not put non-running software in the running disk; update patches in real time. Eight: Anti-virus software and firewall: At least one effective and genuine anti-virus software and frequently upgrade the virus database: firewall settings are appropriate (not too many, too high, too low); viruses can make the computer slow down, freeze, disconnect, freeze, and repeat Startup and switch failure. 9: The connection, contact and insulation are good. 9.1 Network cable and crystal (R45) head: Are the crystal head and socket plugged in properly (are they loose)? Is the contact good? What is the contact resistance? Is there any dust accumulation? Is it oxidized? Has the mechanical locking of the crystal head and base been locked? Is the latching secure? Are the network cable and crystal head tightly pressed and in good contact? The line-to-line insulation resistance of the network cable (using a 100V megger) should be greater than 20 megohms. 9.2: Click Computer, then open the Device Manager, find the network adapter, click Disable, then start it again, it may be fine.If it doesn't work, don't be angry! There is no such thing as a cow that suffocates to death, only a stupid man; 9.3: If it still doesn’t work: take a look at the following methods, you might as well adopt the measures that you think are acceptable, and treat your love machine With a thorough decluttering, you won't have this happen to you. 9, 4: For up to half a year, users who frequently access the Internet should open the shell of the device after powering off (by the way, check whether the internal connections of the device are good, whether the memory module is loose, and whether the memory module is in good contact with the card slot? Are the plug-ins loose? Are they plugged in tightly? No? Are the connection points firm and in good contact?) and clean the dust inside the device. ★Copyright statement: This answer is original to "Harmony" and no one may steal it!★ 10: Power supply Is the power supply stable? Are voltage fluctuations within the allowable range? Is the ripple coefficient of the A/D converted power supply qualified? Due to equipment over-voltage (like feeding a child, too much will make him or her dead), low voltage (like feeding a child, too little will lead to malnutrition), and excessive voltage fluctuations (like feeding a child, one meal when hungry and another when full) (indeterminate amount), overcurrent, and heat, causing the overheating protection action to cut out the fault and remove the equipment from operation (i.e., slow, delayed, repeated starts, delays, dropped calls, interruptions, disconnections, automatic shutdowns, crashes, etc.) Like), etc.; 11. The button battery on the motherboard has insufficient battery capacity or no power, and it will also fail to boot or cause other malfunctions. As long as you follow the above instructions carefully and do it regularly, your equipment will work smoothly and you will feel comfortable; even a computer with low configuration can make you very satisfied; otherwise: no matter how high the configuration is, Computers will also break down frequently; just like people wearing clothes (Skid: Chen Peisi in The Good and the Bad Guys: No matter how good the clothes you give him, he can't go up to the next level!), the clothes are clean and neat, no matter how high the level is. No matter how high-end your computer is, if you don't follow computer safety maintenance and usage methods, you will have constant failures and frequent accidents. Many failures are man-made, everything depends on man-made things! ★Copyright statement: This answer is original to "Harmony" and no one may steal it!★ Don't forget to accept my answer!
