问题描述

风扇噪音很大。
system node environment sensors show 表示受影响节点的风扇速度高于其他节点的风扇速度。
SP-LATEST-IPMI 登录AutoSupport 还表示受影响节点的风扇速度高于其他节点的风扇速度。

示例：

受影响的节点：

FAN1: Fan1_Status | 0x0 | discrete | Ready | na | na | na | na Fan1_Current | 7.900 | Amps | ok | 0.000 | 0.500 | 10.000 | 12.000 Fan1_Speed1 | 8400.000 | RPM | ok | 1000.000 | 1250.000 | 9750.000 | 10000.000 Fan1_Speed2 | 8400.000 | RPM | ok | 1000.000 | 1250.000 | 9750.000 | 10000.000 Fan1_Speed3 | 8350.000 | RPM | ok | 1000.000 | 1250.000 | 9750.000 | 10000.000 Fan1_Speed4 | 8400.000 | RPM | ok | 1000.000 | 1250.000 | 9750.000 | 10000.000 Fan1_Volt1 | 11.940 | Volts | ok | 10.560 | 11.160 | 12.840 | 13.440
