Laptop CPU Fan Thermal failure

Laptop CPU fan thermal failure

1, CPU fan shutdown causes panic

Failure phenomenon: The CPU fan of the notebook computer sometimes stopped, resulting in high CPU temperature and panic.

Troubleshooting: The current mobile CPU basically has a temperature protection function. When the CPU temperature exceeds a certain limit, it freezes or reboots, protecting the CPU. If there is a problem with the CPU fan, should be sent as soon as possible to troubleshoot, to ensure the normal operation of the fan.

2, the CPU fan installation is not in place to cause frequent crashes

Failure phenomenon: An IBM T42 notebook computer, as long as the start-up, running for a period of time will be slow, and there is no reason to panic and automatic restart of the phenomenon.

Troubleshooting: Because the CPU fan is noisy, the CPU fan of the notebook computer has been removed and cleaned before. Therefore, it is possible to determine the CPU fan problem, causing the CPU temperature is too high and there is a problem. Once again to open the notebook computer view, it is T42 original CPU fan screws are not installed in place, reinstall after the failure has not occurred. Failure comments: If the crash and restart is not due to the virus and improper use of the cause, it may be the temperature of the CPU caused by too high. If the CPU cooling fan of the notebook computer is not good, resulting in high operating temperature, it may cause frequent crashes.

3, CPU cooling duct congestion caused downtime

Failure phenomenon: A Lenovo Sun 420A notebook computer, the boot work one hours after the sudden shutdown, after a while can be turned on, open and shut down.

Troubleshooting: Since you can turn on the hardware system is not a problem, may be due to high CPU temperature, automatically turned on the protection function and downtime. Open Notebook Computer Check, did not find the problem of CPU fan, take apart the heat duct, found that some of the air duct is blocked (such as figure), after cleaning the notebook computer recovery, troubleshooting.

4, laptop CPU fan Turn off

Failure phenomenon: Toshiba M2 notebook computer, after using for some time to find the CPU fan sometimes turn not turn, But the body temperature is always high.

Fault handling: The laptop fan is designed with temperature control, which rotates when the CPU temperature is above 70 ℃. The high temperature of the fuselage does not mean that the internal temperature is really high.

5, the Notebook CPU fan has been rotated

Symptom: A laptop, the fan is running a normal program (such as word, browsing the web) 5 minutes to turn once, the duration of 5-6 minutes. If you run a program that is too large (such as 3DS MAX), it speeds up the rotation and makes a lot of noise.。

Troubleshooting: This is a normal phenomenon, the laptop fan for temperature control design, only to reach a certain temperature will rotate, some use AMD processor notebook computer, the power consumption is relatively large. So the fan will rotate more frequently than other models, and the rotation will be more normal when playing a large game.

6, the laptop's CPU fan does not go to the

failure phenomenon: A laptop computer, found that the CPU fan in the computer running to the back panel is very high temperature still do not turn, then suspected that the CPU fan is broken. Later found that the computer started self-test will turn, indicating that the fan on the brake is not a problem. But I don't understand why the back panel is still in high temperature.

Troubleshooting: The CPU fan is mainly for CPU cooling, and only when the CPU temperature is above 70 ℃ will rotate for its cooling. In addition, the problem of high back panel temperature is not necessarily caused by the CPU, hard disk, memory, graphics and motherboards and other accessories of the heat may be gathered here, so the back panel temperature is too high and CPU fan is necessarily connected. In addition, it is recommended to run a large game at the same time test, if the CPU fan does not turn after a period of time, it may be the problem of the CPU fan. The

handles the problem of CPU fan cooling to make the notebook work properly. Therefore, when we buy a notebook, when considering the notebook configuration problem, but also consider the laptop CPU fan cooling performance, such a notebook life will be a little longer.
