As the core component of enterprise information system, the normal operation of server is critical to the stability of business. However, if the CPU temperature of the server is too high, it may cause a series of serious problems, affecting the normal operation of the business and the stability of the server.

High server CPU temperature may cause the following effects:

1. Performance degradation: High temperature will cause the CPU to automatically reduce the frequency to prevent overheating, which will reduce the performance of the server. Frequency reduction will reduce the processing capacity of the server, resulting in slower operation speed, affecting business performance and user experience.

2. System stability reduction: High temperature may cause instability of the server system, or even system crash or crash. This will lead to service interruption, data loss and business interruption, which will have a serious impact on business operations.

3. Hardware damage: Long term high temperature will damage CPU and other hardware components and shorten their service life. Excessive temperature may cause problems such as internal structure expansion and metal fatigue of the CPU, which will eventually lead to hardware failure and need to replace damaged parts.

4. Increased power consumption: When the CPU temperature rises, the system usually increases the fan speed and other cooling measures to reduce the temperature. This will increase the energy consumption of the server, resulting in an increase in the cost of electricity and a waste of energy resources.

5. Increased security risk: High temperature may lead to server hardware failure, thus affecting server security. For example, hardware failure may lead to data damage or loss, making the server vulnerable or increasing the risk of data leakage.

Therefore, keeping the server CPU temperature within the normal range is critical to ensure server performance, stability and security. Appropriate cooling measures, such as increasing fans, improving air circulation, optimizing server layout, etc., can effectively reduce CPU temperature and reduce the above impacts.
