Old NAS with two concerns

Lolply · May 6, 2021

I have an old synology diskstation DS411+ii, it has been in storage with hard drives inside for about four years (both in a closet and a shed). So far it has been working fine.

first concern: it contains four hard drives. Two of wich were damaged and has been changed from Sagemcom 4 tb, to Samsung 4 tb. The data is okay. The two remaningSagemcom drives is equally old. But one is running at 36-40 degrees celcius, and the other one at 29 mainly.

Is it a sign of near failure, and should i be worried?

second concern is about startup. When ever the NAS is powering up the cou fan makes a loud rattling sound.

currently i havent made a backup, because i am afraid what might happen.
if i cant save the nas i might just buy a new one.

Thank you

Drive temp depends on many things, where the disk is located, how it is used, etc.

If you mean the cooling fan on the back that should be a standard 3 wire jobbie, measure the dimensions and you will be able to easily find a replacement for it. (make sure the new one matches the original's specs in terms of airflow and static pressure)
