Hello Dear Team -

So, simple question with simple answers and comments.
The background: everytime the Fan of my "5Big Net2" turns on, it is always "full speed" and it can be very annoying.
Would there be the possibility to have the Fan either manual or automatically controlled, but in terms of different levels?
I mean: 25%, 50%, 75% and 100%....

I don't remember if it was with the original firmware from LaCie either full on or full off... but different speeds instead of full on would be appreciated.

Cheers,
Marco

Hi

Nope, it is not the expected behavior unless jobs with many I/O disk access like p2p feature (transmission, resilio, ...) are running on your nas.

First check is the fan is really running

Code: Select all

ps auxf|grep fan-d
root      1105  0.0  0.2   1808  1324 ?        Ss   Jan03   0:07 /usr/sbin/fan-d
root     26844  0.0  0.4   5828  2348 pts/0    S+   14:14   0:00  |       \_ grep fan-d


so you should have a line "/usr/sbin/fan-d"

2d check : read disk temp history on sda sdb,...,sde

Code: Select all

smartctl -l scttemp /dev/sda

(change by sdb ...) and then examine on each disk if on the last 30 days, temp disk always stays high (>60°) information are on the lines

Code: Select all
