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.

- Ok, did some more searching and found out a couple threads. Granted, none of them have the same problem I have, but there are several threads describing how to replace the fans, particularly
http://www.readynas.com/forum/viewtopic.php?f=24&t=39652
I still do have a couple of questions:
The documentation talks about a third fan, Disk exhaust fan. But nobody has talked about replacing it. Is is a new addition, or has it been removed, or something else?
The documentation talkes about the following specs:
– Software-controlled 120 mm chassis cooling fan
– 90 mm CPU cooling fan
But other users talk about NF-R8 as a CPU fan replacement. But that is a 80mm fan. Getting confused here. I guess I have to open the case and measure the fan? - OK, looks like I've created a thread where I talk to myself.
I opened the case and found the fans, and proper replacements for them. Also, the current upper fan (the disk fan) is not turning at all, and the Health page now says "Out of Spec" and says "0 RPM". The front panel at boot said "SYS fan failed". Pretty clear. The third fan I was talking about was the power supply fan, which I understand is not smart to tamper with. Oh, by the way, the case was quite full of dust after these 4,5 years (altough I have used compressed air to clean it, but without opening it).
I'm replacing the SYS fan with Noctua NF-P12

The CPU fan will be replaced by
Noctua NF-R8 (comes with a 3:4-Pin Adaptor)
http://www.noctua.at/main.php?show=productview&products_id=9&lng=en
As I open the case I'll even add an extra memory. The nerd in me can't resist upgrading.
So I guess I have no questions left. :D - Your NAS will take 8GB (2x4GB) RAM.

Make sure you prevent the fans from turning while you're blowing the dust out; spinning them up to high RPMs will make their bearings fail.apoleon wrote: I'm replacing the SYS fan with Noctua NF-P12

If you haven't purchased those fans yet, better choices might be the NF-S12A FLX and the NF-R8 PWM.
Your NF-P12 can generate high static pressure -- good for forcing air through the tight spaces you might find in CPU coolers, etc. -- but the Pro Pioneer's case fan doesn't need that; all it wants is high airflow, and the NF-S12A FLX can push 20% more air than the NF-P12.
The NF-R8 PWM is just like your NF-R8, but has a 4-pin connector.apoleon wrote: As I open the case I'll even add an extra memory.
The Patriot PSD28G800K (2 x 4GB) will work well in the Pro Pioneer.If you haven't purchased those fans yet, better choices might be the NF-S12A FLX and the NF-R8 PWM.
Thanks for the tip. I was actually thinkinf og the NF-S12A FLX, but wasn't sure if it would work so I decided to take the safe route. But I changed my order as you recommended. I should have two new fans by the end of next week, after which I will have more fans than Justin Bieber.The Patriot PSD28G800K (2 x 4GB) will work well in the Pro Pioneer.
Holy cow those are expensive. I'll settle for 2X2Gb for now :)
Thanks everybody for the tips!- You definitely want 4-pin PWM fans, or they are going to run full speed all the time. Also the "3-pin to 4-pin adapter" that those come with is, I believe, an adapter to a 4-pin disk drive style Molex connector.
I replaced a CPU fan with an Evercool EC8015HH12BP. It has fewer, but larger blades than the original and thus runs quieter and at a lower pitch. The max airflow is a little less than the original, but I've never seen it running at full speed except during a boot, so it shouldn't need it. A Delta EF0812DB is another option with a little higher airflow spec than the original, but it has even more and smaller blades. Mine didn't fail completely, but the bearing was getting noisy and it was just a matter of time.
The power supply fan is certainly replaceable if it should fail, but I wouldn't suggest doing so just because you can. It doesn't seem to be a big noise contributor. I had a supply fail and pulled the fan from the old one just in case I need it in the future. It is just a two-wire "dumb" fan.
I have always found the CPU temperature to be rather low and have wondered if the two temperatures are reported backwards. My CPU temp is always reported lower than the case temp, which seems odd. When my drives are spun down, I have had the CPU temperature reported at or even a little below ambient room temperature. I highly doubt that to be the case. I can easier believe that of the case temperature, the slightly below just being lack of calibration.

Odd but true. The CPU, with its big heatsink and powerful fan, runs at close to ambient temperature whenever it's not heavily loaded. The heat from the CPU has to go somewhere, though, so it's transferred into the case. The drives get warm, too -- typically 10-20 degrees C above ambient -- and they also radiate heat into the case. The case fan draws cool air in and through the case, but there's a lot of mass in there to cool down, so the SYS (case) temperature typically equalizes to around 10-20 degrees above the drive temperatures.
You can see for yourself that the CPU and SYS temperatures are reported correctly by putting a heavy load on the CPU and watching the temperatures. CPU will rapidly spike; SYS, if it increases at all, will do so much more slowly.Sandshark wrote: When my drives are spun down, I have had the CPU temperature reported at or even a little below ambient room temperature.

Yes. The CPU's temperature sensors are not extremely accurate.- Ok, everything almost OK.
Got 2 x 2 GB DDR2 memory, installed fine, works fine.
Got Noctua NF-R8 CPU fan, installed fine (a tight fit), works fine.
Got Noctua NF-S12A FLX fan for the SYS fan, installed fine, but doesn't rotate as fast as I think it should.
So, the ReadyNAS Pro Pioneer I have is up and running and very quiet. Both fans rotate and I can feel the airflow, altough the one fro the SYS fan is quite weak.
Status > Health says the SYS fan is currently doing 1288 RPM and CPU fan 912 RPM.
SYS temp is 72 C / 161 F, which is more than the normal range (65 C / 149 F).
I have calibrated the fan, but there seems to be no change in the RPM, or a very small one. I did install ToggleSwitchProCPUFan_1.0-x86.bin and booted. It said the install and fan speed adjustment was successful, but there is no change.
Any ideas what to do to make the Pro Pioneer make the SYS fan rotate faster?
I plugged the fan connectors to the same plugs the old ones were in. - A screenshot of Status > Health
http://www.lintukoto.net/muut/jakorasia/download.php?id=589168923 - Noctua site says the NF-S12A FLX can only go to 1200 RPM ±10%. So it is working OK.
But the system is just too hot. Is this fan underpowered for my needs?
