My Synology NAS makes unusual noises. What can I do?

Purpose

This article provides you with instructions on how to identify sources of noises from your Synology NAS.

Resolution

A Synology NAS in operation may emit some noises. Possible factors of noises include:

  • Drives
  • Fan
  • Vibration of the drives and drive trays
  • Others

To identify the cause of unusual noises:

  1. Shut down your Synology NAS.
  2. Remove all drives and drive trays.
  3. Power on the device again without installing any drive trays to check if the unusual noises persist.

If you hear no more unusual noises:

  • The noise you heard may be the vibration of drives and drive trays. If so, we suggest replacing the fastening panels with screws to reduce the noise.
  • The noise may be caused by the drives you use. You can use a different drive to fix the issue.

If you still hear unusual noises:

  • The noises may come from the fan or the device itself:
    • Try cleaning up the dust inside the device and on the fan.
    • Check if the fan screws are fastened.

If you think the fan is making too much noise:

  • Try switching the Fan Speed Mode to Quiet Mode by going to Control Panel > Hardware & Power > General.

  • If switching to Quiet Mode still doesn't solve the problem and your Synology NAS is out of warranty, you can check the fan model for your device here and purchase a new one for replacement.

If your device is within warranty and its fan malfunctions, or if you still cannot find the cause of the unusual noises, please contact the reseller from which you purchased the Synology NAS for the RMA service.

If you are still bothered by the noise when the NAS is idle:

  • Set up scheduled shutdowns and startups to have your Synology NAS run only when you are not sleeping.

Notes:

    • The fan speed mode options are only available on Synology NAS products with system fans.
    • The fan speed mode options on your Synology NAS vary depending on the hardware specifications and configurations. When you install additional network interface cards, some fan speed options will be disabled to ensure optimal heat dissipation.
