Fans of WLAN devices make a big noise
Fans must operate normally to ensure normal operation of WLAN devices. Inefficient heat dissipation increases device temperature and may damage device hardware. A big noise may be generated when fans run at the full speed for dissipating heat of WLAN devices. Run the display temperature command to check the temperature of a WLAN device. If the device temperature is too high, lower the temperature first and then run the display fan command to check whether the fan still works at the full speed.

Problem and solution of loud fan noise due to overheated temperature of the disk
You can take the following measures when loud fan noise is caused by overheated temperature of the disk: 1. Issue Description Product and version information ? S2600 S5000 series The application server runs Windows 2003. After a faulty disk is replaced on the storage device, data on the hot spare disk cannot be replicated back and fan noise becomes louder. Check the replaced disk and find that the replaced disk has a temperature of 119°C. 2. Alarm Information On the ISM menu, choose Event > Event Management. On the Faults tab of the displayed Event Management dialog box, an alarm Above upper major threshold is displayed. 3. Handling Process Replace the disk. Note: The disk used to replace the faulty disk must be the same type of the member disk in a degraded RAID group, and the disk capacity must be greater than or equal to the minimum member disk capacity in the RAID group. 4. Root Cause Remove the new disk. The fan noise is lowered. Conclusion: The loud fan noise is caused by overheated temperature of the disk. 5. Suggestions None
