Reducing CPU temperature and improving the stability of computer system

With the development of computer technology, the working frequency of CPU is more and more high, and the fever is more and more severe. CPU manufacturers are recommended to the CPU using "heatsink + fan" heat dissipation, but, in the use of the heatsink and fan, the cooling effect is not very ideal, due to CPU overclocking caused heat too large and the phenomenon of panic.

The author has been repaired by the motherboard for the intel,cyrix6x86/133mhz/8m/2.1g configuration of the PC, DOS operating normally, and into Windows "panic", then touch the CPU is very hot, but the CPU heatsink and fan are normal, Measuring the working voltage of the CPU is also correct. Try to change the CPU frequency from 133MHz to 120MHz, boot run Windows Normal, CPU temperature is normal, there is no "panic" phenomenon. This case shows that the high and low CPU temperature directly affects the stability of the system. Due to the CPU is a large production of heat, good cooling measures is to ensure the stable operation of the system is an important measure.

To the CPU cooling, can be divided into two types of software and hardware. Because the speed of the CPU and slow peripheral devices such as hard disk, CD-ROM, keyboard, there is a poor rate, so that the CPU is not running busy large software, every moment there is a large number of relatively idle time. Software cooling is the use of software tools, when the CPU is relatively idle to execute a HLT machine instructions and the CPU into the energy-saving suspend mode, so that the CPU to reduce the energy consumption. Hardware cooling is to open the chassis, by adding some electronic components to improve the working environment of the CPU, forced to reduce the operating temperature of the CPU.

One, software cooling: Cpuidle and waterfall.

1, Cpuidle is a veteran "software air-conditioning", its use is simpler, under Min9x can be placed in the "Start" menu automatically, to WIN95 as an example, the specific steps are as follows:

(1) Cpuidle all documents into the hard disk, such as stored in the C:\Program file\cpu\ directory;

(2) Click the Start button, turn on the setup/taskbar/Start Menu program/Add, and in the Create Shortcut dialog box, enter the path where CPUIDLE.EXE is located, such as C:\Program File\cpu\cpuidle. EXE, and then click Next;

(3) In the Select folder to place Shortcuts dialog box, click the Startup folder, and then click Next;

(4) in the name of the selected shortcut dialog box, enter the name of the program you want to add to the Startup menu, or use its default value of Cpuidle, and click Finish.

(5) Reboot the system. Cpuidle also includes a DOS version of the executable file is DOSIDLE.EXE, you can use it into the C:\DOS directory, and then add LH C:\DOS\DOSIDLE in Autoexec.bat file. EXE sentence, reboot the system.

Cpuidle software can generally reduce the temperature of the CPU 5~10℃, while it can improve the performance of the CPU. Because many CPU-included performance tuning options are set by default to disable at the factory, Cpuidle can activate these options.

2, Waterfall is a self-contained install software, it supports the CPU includes Pentium, high-energy Pentium, Pentium Ⅱ, K5, K6, K6-2, 5x86, 6x86, 6x86mx and so on. After loading the waterfall into the system, it will add a shortcut to the Start menu, which will automatically run every time you enter Windows, and a small icon will appear in the taskbar, which can be used to observe the running state of the waterfall, and to control the software by clicking on the icon. You can also use the right-click shortcut menu to open the waterfall Monitor to see how the waterfall is running. With the old cool software cpuidle compared to the waterfall program code to be much shorter, and cooling ability greatly stronger than Cpuidle, while the security can also be stronger, unlike cpuidle that will often occur restart, can not shut down and the phenomenon of panic. The waterfall can reduce the CPU temperature 30%~70% without affecting the CPU performance, thus greatly improve the working stability of the machine.
