DS920+ overheating

[angelsurfer]

Hi All,

I have had my Synology DS920+ for about two years already.
I noticed lately that it is sometimes running on a high 60s to low 70s in temperatures.
I have my fans on full powered since I started using it.
Should I be concered about changing my fans or opening it up to do a more thorough cleaning?
I don't know how to reduce the temperature.
Thank you.

Maybe you can place the NAS in a better-ventilated place or cooler room like a basement. Otherwise, clean it thoroughly. New fans might not help.
