Has anyone changed the fans in their 5200? Mine is like a hoover on full thrust! If so, please give details. Cheers, Andrew.

Hehe...
I've put my 5200 in another unused room. It can be as noisy as it wants ;D

long term: give it a year (hopefully!) and NAND flash hard drives will drop in price and go up in capacity then we can say goodbye to the fans all together!
short term: Quicks advice is good! but I believe there are some fan mods in the 2100 section which may help as a starting point?

I'm trying to cut off noise from the multitude of machines at my place. Now the 5200 is the biggest culprit I would love to quiet it down, but I'm not willing to replace the fans just yet - last thing I need is a 750GB drive breaking on me If anyone is daring enough and uses moderate usage of the N5200, post the fans that you used. Thanks, Foo

I've put a Nexus Real Silent 92mm 19,2dBA-fan in my N5200 and it reduces the noise quite a bit. Still, there's some noise left, but I'm pretty satisfied. The disks haven't been affected and the SMART-readings show that the temperature is unchanged.

Just got a 2nd one and both are fairly quiet. For comparison our Cisco switches drown out the N5200 completely.
The 2nd device is now on my desk in my home office and it's very quiet. Either Thecus has updated the fans or I'm deaf and can't hear it - from the reviews I expected these to be loud but they're not. When my laptop fan comes on it's louder than the n5200.

So here's the stats:
1) New fan mentioned above: Airflow: 27 CFM Rotation speed: 1500 RPM Acoustic noise: 19.2 dB(A)
2) My fan that came with the thecus: Airflow: 32 CFM Rotation speed: 2000 RPM Acoustic Noise: 23.5 dB(A)
So it looks like I can expect a 20% improvement in noise levels. I have so many fans in my office, any option I can take I'll do (while avoiding annoying water coolers)..

Here's another possibility:
Is there a compatible fan out there that will vary the speed according to the temp? When my drive isn't running, I noticed the air coming out is not hot at all - guess that's the safest setting.
I also added some dampeners inside the case - didn't do that much but enough to be noticeable (like all dampeners). I also placed my thecus on the floor, further away from me.
I guess this will do for now. It would be nice to see the thecus control the fan speed though.

I did change both fans, but my concern was cooling, not noise. Actually, the noisy one was the PSU 40mm Superred fan. The bearings seem to be subpar. You can upgrade it to a silent Papst one (for instance a 412/2), they last forever. To plug it instead of the stock one, you'll have to remove the fan connector white plastic socket of the PSU to expose the 2 pins and jack your 3 pin connector on them (+ with +, - with -, careful ...). As the fan will be weaker than the previous one, you should reverse it (blow inward) as it is competing with the main fan to extract air from inside. It won't win over the big one, and the airflow in the PSU will be stalled. If you reverse it, even if it sounds like a deadly sin, everything should be fine but check the disks temperature, as the stock main fan (Adda), decently quiet, is not that powerful and barely adequate imho to maintain 5 big disks cool, and adding the PSU heat won't help there even if the airflow is a bit stronger. Hope this will help.

Thanks for the update.. When I feel brave enough I'll give this a whirl. How's the temps in your system? You mentioned you replaced both fans - was the result a quieter system?
I understand what you mean about the airflow though. I didn't realize they're both blowing outward.
I also noticed that my system has a side covered up inside with some clear plastic, preventing some of the holes from getting air into the system. I'm not sure what the logic was behind this, but I left it alone.
Thanks for the hint.. I'll update and let you know how it goes.

hmm, didn't change the second fan yet, must investigate I wouldn't use dampeners, I used them once and almost cooked my system then (my old PC - NOT my Thecus , since the dampeners have the effect of keeping the hot air inside instead of the metal giving away heat...

I replaced the original fan in my 5200 with a Sythe kaze-jyu (SY1025SL12M). A 100mm fan that's made for 100 or 92mm space. Very happy with improvment in sound reduction and air flow volume.
Original Fan: ADDA 92x92x25 2700 RPM 50 CFM 33.7 dBA - loud as a train
New Fan: Sythe Kaze-jyu (SY1025SL12M) 100X100X25 (has 92mm and 100mm holes) 1500 RPM 43 CFM 22 dBA - Very large improvment

Thanks to everyone who shared their findings here, I followed the recommendations to silence the n5200 as much as possible. I replaced the 92mm Adda fan by the 100mm Sythe Kaze-jyu and the 40mm PSU fan by an SilentX iXtrema PRO (6CFM, 14dbA).
I tested brunoz' recommendation on mounting the 40mm fan such that it blows air into the box but I found that it provided much less cooling.
I also cut away the fan grill on the psu (I kept the grill on the mounting frame) so that it wouldn't interfere unnecessarily with the air flow. Probably it didn't do that much to the noise but the warranty is lost anyway. Cutting away the grill on the outside mounting frame would have been better but I did not have the tools for.
The noise level is now bearable, the biggest improvement came from the replacement of the PSU fan.
The cooling capacity is adequate despite the reduced air flow. I have 3 discs in the system, the temperatures reported by the INFO module is about 10-15 degrees C higher than the ambient temperature. The PSU is running at about the same temperature.

But unfortunately my 40mm fan is the one making the noise at the moment. So I'll be getting a: Spire FD04020S1H3 40mm case fan measures 40x40x20mm, and moves 10.25CFM at 6000rpm. 23dBA. 3pin connector. www.pccasegear.com.au/prod5426.htm

I replaced the original fan in my 5200 with a EnermaxUC-12AEBS . Yes 120 mm...!!
