set against Intel, forcing x86 to change.
Through decades of technology accumulation, x86 server in the field of server status is almost alone and defeated. The small and flexible x86 server is widely used in the market, and it can be used in many fields such as file, print, communication, web, email, database and application services in the Internet and LAN.
The biggest feature of the x86 server is that it can be compatible with Windows operating systems, all with Intel's CPU. and Intel's x86

rapid discharge of heat. Of course, there are too many thermal holes also have disadvantages, 1. Is the impact of beauty, 2. Is easy to dust, so users need to be diligent, often clean the shell.
Four. Can choose vertical is not selected horizontal
From the display posture, wireless router has two horizontal and vertical design, horizontal models more, vertical less, there are two kinds of can be. We recommend the selection of vertical models, because the vertical display, the fuselage and the
Due to the CPU when the heat generated by conduction to the heatsink to reduce the CPU temperature, and then the fan brought by the cold air blowing the heat away from the heat sink, and the heat of the fan can be transmitted by the size of the heat sink and how much the computer temperature is too high. Generally speaking, the heat sink and the air contact area is bigger, the fan's heat dissipation effect is better, but this kind of argument has cert
veteran veterans, please advise on mistakes or suggestions.
Computer host the most basic equipped with the motherboard, CPU, memory, graphics, power, with these things, the most basic you will be able to boot to see the BIOS, but also need storage equipment (hard disk, CD-ROM, soft disk ...). To be able to execute the operating system or application software, in order to make the computer look like a computer and security considerations, chassis is a general user must, but at this time there
motherboard temperature is very high, may be due to run too much software or large games. In this case the high temperature requires the motherboard for dust treatment and installation of the chassis fan. In addition, shut down unnecessary software, long time to run a large game after the computer to rest for some time. With the computer housekeeper, 360 guards, such as cleaning up the computer. Because the motherboard is the heatsink cooling, no coo
a high temperature solution for the motherboard:
1, if the computer just started the motherboard temperature is very high, is usually the motherboard hardware problems. After the boot, the motherboard temperature increased to more than 65 degrees, open the chassis with hands touch the motherboard on the north-south bridge chipset and capacitance found is not very hot, this is the motherboard hardware problems, need to after-sale or computer repair shop to deal with.
2, if the computer running
1. How to maintain CPU
Q: How do I maintain the CPU?
Answer: First of all to ensure good heat dissipation. The normal operating temperature of the CPU is below 50 ℃, the specific operating temperature depends on the frequency of different CPUs. Heatsink quality should be good enough, and with the speed of the function, so with the motherboard monitoring function with monitoring fan work, the bottom of the heat
, provides the user with the satisfactory experience. It also supports PNP automatic overclocking technology to help players easily overclocking and improve system performance.
Yu-Zhan Panther series DDR4 2400 Memory

Yu-Zhan Black Panther series DDR4 2400 memory heatsink top, through the metal processing, gold and silver Two-color overlapping, strong visual impact. Stylish personality of the
The video card temperature is too high, can cause the computer not to operate normally, then, the video card temperature is too high how to do?
Video card temperature is too high, the solution has two, one is to replace the radiator, preferably with a fan heatsink. The other is to install the fan for the video card's original heatsink.
Some graphics cards use passive heat dissipation, the
Q: My CPU fan has a screw because of the use of excessive force slipping teeth can not be tightened, now 3 screws fixed CPU fan, so there will be a problem?
Answer: Is the CPU fan fixed to the heatsink on the screws? If it is the case directly to change a slightly larger screw fixed also can, if the heatsink is fixed to the motherboard screws (some radiator design) that can only replace the fixed plate or
board of materials used to work quite generally. Careful inspection, found that the motherboard on the capacitor and no breakdown of the phenomenon, the entire PCB board also did not leave traces of burning, so in the end is the motherboard which part of the problem. The motherboard is then again cleaned and then mounted again into the computer to access various devices. After the start of the last half of the phenomenon of the crash, then hand touch the motherboard North Bridge chip on the
1. Add heatsink to Router motherboard
Now home-based routers are not expensive, more than 100 of products are everywhere, if you find the router heat, you might as well open the router shell, to the router motherboard on the chip to install heatsink, although this may lead to damage to the shell, but after all, the price is not expensive, the risk is not big. The heats
motherboard North Bridge heatsink, and replace the heat sink with good cooling effect.
4, if the motherboard of the North Bridge radiator is not fixed, then the North Bridge temperature too high will cause the motherboard temperature too high.
5, strengthen the chassis cooling capacity
Strengthen the body heat dissipation
Because the motherboard is the heatsink cooling, no cooling fan is passive c
