Has anyone thought about removing the cpu fan, cutting a hole in the side of the housing and fitting a 100mm slim fan, something like a Scythe Kaze Jyu Slim 100mm Case Fan?

Unfortunately, the issue is the PSU fan. It is by far the loudest thing on the NAS so replacing the CPU fan will do nothing for quietness.
At least that's the experience with my NAS and I would hazard a guess applies to most people with the 5200Pro.
Your mileage may vary though.
Cheers

do you need to open the actual power supply to replace its fan, or is the fan mounted next to it?

I've done it and it's not difficult to do (a few screws) The biggest problem of the PSU fan is the RPM it runs at - it pushes alot of air thru the grill covering the outlet leading to the loud howling sound in my case. I replaced it with a lesser RPM fan that pushes about the same amount of air and cut away the grill for better airflow and it's still loud (the loudest thing in a small room) but at least it's bearable unlike before!

which fan did you replace it with? how much air does it need to pass?

Scythe Mini Kaze Ultra 40 x 20 mm Silent Fan is ideal so long as you dont have the thecus in a very hot room running at 100% all the time.

The PSU-fan is the most loudest indeed. I had my PSU replaced for a new one (under warranty) because of a failure and that fan was a bit less loud. I did remove the CPU-fan, because that one also caused some noise, and replaced it by a nice and quiet 140mm fan. This fan fitted exactly near the holes on the side and in the chassis. CPU temperatures are fine. But still...I think it's to noisy. Maybe because I came from a complete silent N2100 (check: thecususergroup.proboards.com/index.cgi?board=modifications&action=display&thread=508 )

Can't we just replace the whole PSU with one that sits outside the box? Is there such a thing available?

yep of course you can, it's just a standard atx power connector.
I'd thought (long time ago) about removing my psu entirely and replacing it with a DC-DC convertor powered directly from the 12v batteries in my ups...no fan at all and probably a little more "green". Never got around to it, yet.

The internal adapter won't fit in the Thecus at 43mm. Which means both adapters would have to be external to the Thecus. If there were only a single adapter then that's fine but both? It's also very expensive. The other interesting solution is to use a much quieter 40mm fan (reduced cfm) but reverse it so it's blowing into the PSU - I believe someone already did this a couple years ago for a much quieter NAS. I believe they may have also removed the top of the PSU to allow heat to escape easier due to the less powerful fan pushing air into the NAS - not too sure.

hmmm, but I wonder if I could live with it all hiding round the back?
It is very expensive though, but I really want a no-fan solution. I'm building a custom cabinet with big quiet fans for extraction and am also seriously considering investing in some heatsinks to stick around the case.... with 5 disks my n5200 is pretty noisy!

I haven't checked but there should be other 200W fanless designs that don't required 2 adapters - the 2 adapter design just seems so...unnecessary. And you're right, we don't really need a fanless PSU fitting inside the Thecus, sitting out back is fine If you do find something please share with the forum as I'm also kinda interested...although in saying that I already have a spare PSU in case the current one dies

It is difficult to find one that is 200W! There are 300/350w ones and above, can't we use one that is higher powered - wouldn't it just run cooler? or there is something like this: www.orbitmicro.com/global/pw-200-m-p-2024.html ... I wonder if it would be enough to power 5 disks?
