PowerEdge：配备标准散热器的服务器的空闲 CPU 温度较高
摘要: 当服务器处于空闲状态时，CPU 可能被认为很热。

症状
当作系统 （OS） 处于空闲状态时，配置了较低功率处理器的服务器可能看起来很热。
原因
标准散热器不具有与高性能散热器相同的冷却特性。这就是为什么它们被严格限制为低功率处理器的原因。
解决方案
这是正常现象。
功率较低的 CPU 附带标准散热器。高性能散热器不适用于具有较低功率 CPU 的系统。
安装和服务手册 （ISM） 概述了基于功率的 CPU 到散热器。
所有标准散热器都旨在在高负载下为处理器提供足够的散热。
预计在空闲期间会遇到更高的温度。这不是故障或缺陷。
空闲状态下的处理器温度可能未达到 CPU 目标温度，无法在这些空闲时间触发高风扇输出。CPU 温度在规格范围内。
如果习惯于使用高功率 CPU 和高性能散热器，这可能被认为很高。这些 CPU 温度在规格范围内。
这适用于所有 AMD 和英特尔处理器，无论型号如何。
如果冷却是一个问题，可以在 iDRAC UI 中修改散热响应和风扇调整。
- 散热配置文件优化 -允许多个设置。最大性能可在空闲时提供更高的风扇速度。
- 风扇速率偏移 - 允许在基准风扇速率的基础上增加风扇速率（按偏移百分比值）。
- 阈 值- 可以使用此选项设置最低风扇速率。

这些选项允许用户自定义调整冷却，以降低空闲时处理器感知到的高温。有关更多信息，请参阅 iDRAC9 用户指南，了解如何使用 iDRAC Web 界面修改散热设置。
