Ultra 2 Plus - not silent
I use NAS mainly for Squeezebox Server. The device is placed in my living room where I listen to the music. I can also move it to the bedroom. In both cases this needs to be quiet.
So far I used fanless Qnap TS-119. It has passive cooling through the metal case. It is completely quiet (I use WD20EARS which is very silent HDD). Unfortunately it appeared to be underpowered to serve HiRes music. I needed something based on Intel Atom. As there is no one-bay D525-based NAS I decided to give a try to two-bay NAS and use only one HDD. There is no fanless two-bay NAS so my choice was ReadyNAS Ultra 2 Plus.
I must admit I am very disappointed by the noise generated by the device. It is as noisy as my fossil desktop PC (with 200W power supply).
There is no way to place it neither in the living room nor in my bedroom.
The problem seems to be related with "Temp 1" sensor. It should work in the range of "0-80 C / 32-176 F" but in my case it is constantly close to 80 C and occasionally exceed it to 81 C and place a warning in the logs.
After the power up it starts with 40 C with fan speed of 700 RPM (silent).
Then within 10 minutes it goes up to 77 C and fan became noisy at 1200 RPM.
Then I get following 5 minutes long pattern:
77 C, 1200 RPM - noise / acceptable
78 C, 1500 RPM - noise / annoying
77 C, 1800 RPM - noise loud / unacceptable
76 C, 2000 RPM - noise very loud (can hear from the other room) / makes me sick!
72 C, 2050 RPM - crazy noise
71 C, 1500 RPM - noise / annoying
70 C, 1200 RPM - noise / acceptable
71 C, 800 RPM - silent
74 C, 700 RPM - silent
76 C, 1200 RPM
77 C, 1500 RPM, and so on...
My laptop (Lenovo T510) is constantly quiet, my parent's nettop Asus Eee Box 1501P (D525) is also constantly quiet. In comparison Ultra 2 Plus is annoyingly noisy.
Is this correct behaviour for Temp 1 to be always close to 80 C ?!
Temp 2 is constantly at 33 C (Normal 0-65 C / 32-149 F), HDD is at 30 C / 86 F placed in bay 2. There is empty HDD frame in bay 1.

- What version of RAIDiator are you running? There was a known issue with 4.2.16. Please update to the latest firmware (currently 4.2.17: http://www.readynas.com/RAIDiator_x86_4_2_17_Notes)
Also having two disks installed would allow for better airflow and should mean the NAS would be less noisy.
If using the default X-RAID2 adding a second disk would give you redundancy so that if one disk were to fail you wouldn't need to restore from backup. - I use 4.2.17 and do weekly backup to the second HDD in external USB3 enclosure. No need for RAID 1 (additional power consumption).
It sounds weird for me to add second disk to avoid noise. I don't think it would decrease Temp 1 sensor temperature.
It looks like Ultra 2 Plus was not designed for living room or bedroom use. Yesterday I moved it to the bedroom and it couldn't stand the noise at night. Needed to turn it off completely. - I don't know if this can help ....
I changed the original fan of my Duo with a new PAPST SLIM 60 MM FAN - REF 612F/2L that I found on pc-look.com.
Now I can sleep close to my ReadyNas ! - Hi Karoluch,
I have not the Ultra 2 Plus, but the Ultra 2. I bought it mainly for the same purpose as you (SBS), and I also have it in my living room, but I have no problem at all with the noise level. For me it never goes over 1200 RPM. In 95% the fan speed is 800-900, in 5% it is 1200. The Temp CPU is always around 72-74C.
The room temperature nowadays is around 24-26C.
We had some very hot days here and then the room temp was really too high (around 30C). On those days the average fan speed was bit higher, I'd say mostly around 1000-1200 RPM. But even then -as you write- the noise level is still acceptable.
Unfortunately my comparison might not be valid because you have Ultra2Plus, but I don't think that the typical 1500-2000 RPM values are normal.
What temperature levels do you have in your room? - By the way, I also read it somewhere that adding the second HDD helps. They say the airflow was designed and calculated with the 2 HDDs.
(I have two in my Ultra2)
