OS6 on a legacy device in 2018.
Hello there NAS-owners. Starting this thread instead of me going off topic in the thread about ’restriping’. I just switched from OS4 to OS6 and so far i am happy with the change. The new OS is ...

Do you recall the temparature of the disks at the time you measured the above?
Kind regards

50c for the CPU is quite normal, 62C for the system is not. In addition to the disk temps:
- Where you monitoring temps with 4.2.31, and if so what temps were you seeing under load?
- What speed was the chassis fan running at during the resync?
- What cooling profile did you choose (quiet, balanced, or cool)?
Maybe post the temp graph on the performance page.
Note you can test again by running a scrub from the volume maintenance settings wheel - that will create a load that is similar to a resync.
It is possible that the chassis fan needs to be replaced. Of course dust could also be interfering with cooling, so if you haven't looked for that lately, you might want to do that.
- The temps under OS4 was around 34-37 for the drives, something like 43 for the system and 50-57c for the CPU. Something like that.
I remember that the CPU was climbing up to perhaps 58c at one time.
During the resync now i changed it to Cool and it was running at around 900-1100rpm.
Mostly above 1000rpm.
Yes, i’m going to open it and have a look. I want to replace the fan for a fan with alot of pressure and rpm, it is PWM right?
- I sure do, they were around 34-36c.
I really need to open it up and have a look. When replacing the 12cm fan, it is a PWM fan right? I think i’ve read that somewhere.

But keep in mind that the temp reports might be reported incorrectly. Hopefully another Ultra-6 user running OS 6.9.4 will chime in.
not sure how close they are in hardware, but my ultra 4 temps are;
disks: 34 to 41c
cpu fan 1318
system fan 1016
cpu temp 51c
sytem temp 61c
profile quiet
load: idle (its only a backup destination now)
