Now in the computer market, you will be pleasantly surprised to find that computers with more than 1Ghz CPU have become the mainstream of the market. When the CPU frequency exceeds 1 GHz, the maintenance of the hardware CPU becomes a top priority. If it still does not attract enough attention, it will cause the computer to malfunction or even crash and burn. The CPU is like a human brain, and it is also very delicate and can't stand the torture. Therefore, in order for your high-end CPU to do its best, give it a relaxed environment to display its talents. First, there are quite a lot of users in the heat dissipation, although the CPU and the large-capacity hard disk and memory have been adopted, and the small fan is reluctant to spend money on the small fan. "If anyway, it will be replaced by another one." It is just not enough to pay attention to heat dissipation, and save money on the fan, then it will be used in the future, causing this "core" to suffer. So, how should I choose a CPU cooling fan? First of all, priority should be given to the original CPU fan or certified fan, such as Foxconn (FOX045), PK045+, PK889, ALPHA 8045, etc. Generally, the applicable CPU type and frequency range will be indicated on the outer package of the fan. A good fan is not only used by enthusiasts to play overclocking, as long as the CPU of the city's high frequency requires a fan with good heat dissipation to ensure the normal performance of the CPU. Second, the earthquake-proof mentioned shockproof, I believe many people will say, I have never shaken my love machine, why do you start shockproof? In fact, what I call shockproof is not the vibration from the outside world, but the "resonance" from the cooling fan. Now the fan speed can reach more than 6,000 rpm, which is prone to resonance, resulting in the DIE (core) of the CPU being gradually worn out, causing poor contact between the CPU and the CPU socket. Therefore, the cooling fan produced by the regular manufacturer should be selected and installed correctly. Buckle to prevent resonance. Third, shortly before the decompression, a friend's CPU re-heating fan buckle pressure under the huge torment of the gas, let people sigh! After the investigation, the cause of death was that the CPU's DIE was destroyed. Therefore, when installing the cooling fan, the buckle pressure should be moderate, and you must not act recklessly. Fourth, the alarm At present, most of the board has a built-in temperature monitoring probe, the CPU exceeds the preset temperature range (typically 70 O C), the motherboard will immediately alarm, restart or shut down. Therefore, when selecting the motherboard, pay attention to whether the temperature monitoring is built in. When installing, pay attention to the temperature probe to the bottom of the CPU to ensure the accuracy of monitoring the CPU temperature change. In the BIOS of the motherboard, you can generally see the CPU, the current temperature of the main chip and the fan speed information, through which you can judge the operation of the system. Different CPUs can withstand different temperature ranges, such as PIII and P4. Generally, an error message or an illegal operation prompt will appear at around 50 O C. The Athlon and Drill Dragon can work at higher temperatures (90 O C) without problems. Fifth, the home is like a human room, and the spacious living room is refreshing. Therefore, when selecting a chassis, it is advisable to choose a chassis with a slightly larger size and a spacious internal space, which can provide a good ventilation and ventilation environment for large consumers such as CPUs, graphics cards, and hard disks. Since the high frequency CPU places higher demands on the power supply, a 300W power supply that provides a stable voltage input is necessary. There are mainly AMD-certified power supplies such as big buffaloes on the market, and some P4 dedicated power supplies are products that can be considered when purchasing a computer. 6. Dust removal dust is a natural enemy of computer components. Therefore, it is necessary to remove the dust accumulated on the surface of the CPU in time to avoid short-circuiting the CPU. When applying silicone grease, it should be applied on the surface of the CPU core. A thin layer is enough. It will not be good for heat dissipation, and even it will leak to the CPU surface, slot or circuit board. In addition, it is worth noting that when maintaining the CPU, pay attention to the static electricity that comes with the human body. Wash your hands beforehand or touch the metal conductor to eliminate static electricity. Seven, self-diagnosis and normal operation, pay attention to the operation of computer components, such as abnormal sounds, frequent crashes, odors and so on. At this time, to turn off the power supply calmly, open the cover of the chassis and take a look at it to see if there are any signs of looseness in the fan and other components. Because the CPU cooling fan is loose or poorly connected, the motherboard temperature monitoring will automatically turn off the power and restart. If the computer repeatedly restarts and cannot enter the system normally, or the keyboard is locked and stops responding after booting, it may be a CPU fan. Failure, do not force the power on or remain powered for a long time in the state of the crash. This article comes from [System Home] www.xp85.com
