Pro Pioneer fan failed (?)
Hello!
I have a ReadyNAS Pro Pioneer Edition 6-bay NAS device, about 4.5 years old. Running constantly without any major probems (once, however, I had to move all data off and reformat the system due to many file issues).
I was away for one week, and during that time several odd problems arose:
There are entries in the log once about every 15 minutes saying:
Fri May 30 21:30:18 EEST 2014 (null) 1 (null) (SYS 0 rpm).
There are dozens of these.
Occasionally, there is a similar row with slightly different content:
Fri May 30 20:47:54 EEST 2014 (null) 1 (null) (SYS 81 rpm).
or
Fri May 30 16:31:53 EEST 2014 (null) 1 (null) [(null): 0-65C/32-149F, (null): 66.0C/150.8F].
When I go to Status > Health tab of the web UI it says:
Fan SYS 1757 RPM OK
Fan CPU 1939 RPM OK
Temp SYS 54 C / 129 F [Normal 0-65 C / 32-149 F] OK
Temp CPU 22 C / 71 F [Normal 0-60 C / 32-140 F] OK
The CPU temperature seems oddly low, as I believe it is hotter here inside, altough I have not measured it. I've tried recalibrating and everything went fine.
Also, every once in a while (could be every 15 minutes, haven't measured), the device fans go into "turbo mode", similar to recalibration. The, after a while, they slow down again and the noise level drops to normal.
My device has all 6 bays full, each one with a 2 GB disk. The temperature of each disk is around 31 C / 87 F.
I'm running RAIDiator-x86 4.2.26, which is the most recent version at time I'm writing this.
Any ideas? To me it seems the SYS fan is failing/failed, although the Health tab does not indicate anything is wrong. If so, is it possible to replace it? I do have some experience in this kind of stuff, and I don't think I'll destroy anything if I do try to replace. Does anybody know which type/model fan I should buy, assuming this is indeed a fan issue and not simply a broken sensor/software issue?
I could not find a single post in this topic, so at least the problem is not very common.

But the system is just too hot. Is this fan underpowered for my needs?
Hmm, that fan combination works in my system, and keeps the SYS temperature around 60C and the CPU temperature below 30C (ambient temperature is around 22C). What's your CPU temperature?
Are both fans installed in the correct orientation? Air blows toward the label side of the fan, so the CPU fan should have its label facing IN, and the case fan should have its label facing OUT.
By the way, stretching the case side-panel VERY slightly will help it to slide easily over the thicker-than-stock Noctua CPU fan. The easiest way is to lay the case panel (outer side down) on a circular base, with the CPU vents centered inside the circle -- I used a roll of masking tape as the base -- and then tap on the CPU-vent area with a rubber mallet (or a steel hammer with something between it and the case to protect the case) until you've made a shallow, vaguely-circular bulge in the panel for the fan. The bulge only needs to be a couple of millimeters deep; don't overdo it. If you feel like it, you can also extend the bulge into a horizontal oblong shape to make it even easier to slide the panel on. When the case is assembled, the bulge won't even be noticeable without laying a straightedge on the side of the case.fastfwd wrote: Are both fans installed in the correct orientation?

Oh dear. I've never felt this dumb before. Both fans were installed the wrong way. At least I was consistent. Now I feel the warm air coming out the case, and no longer feel the air coming out of the CPU holes (as there is no air coming out). CPU temperature dropped a lot, but SYS temp is still close to the 65 C limit, but anyway within the bounds.
SYS temp was 70 C at 1200 RPM. Now 62 C at 1200 RPM.
CPU temp was 50 C at 900 RPM. Now 30 C at 800 RPM.
Disks are at 36 C, about 8 C lower than before. The ambient temperature is a bit high, 26 C near the NAS box.Note that I replaced one failing disk and resyncing is in progress. I guess that could have an effect on the temperature, too. Thanks again!apoleon wrote: Both fans were installed the wrong way.

I'm glad the problem was so easy to fix.
A resync will definitely make the temperature rise. In fact, the case temperature during a resync is probably the highest that it will ever be. Check again an hour after the resync has completed.
