If it was me, I wouldn't risk too much. Take the case off if you can and don't work the CPU too hard. It's just a couple of days irritation against the (hopefully faint) possibility of burning out something expensive.

I've replaced the fan, and it's running OK now and the temps are normal. However the box is doing some thumbnail creation (weirdly called converting) on the 25000+ images I've got in there. Looking on Synology's forum it's cos of the pre-installed image software and it'll go and create a separate thumbnail for each picture. I've tried disabling the software, but the process stubbornly refuses to stop. It's not really a problem, but it's pegging the CPU at 99% and it looks like it's going to take a few days to finish.
Yep, and having looked at the photo gallery app it comes with, I'm gonna get rid of it, as I'll never use it. Same with the media server app. After a bit of googling I've found a way that is supposed to stop the task.
It's a browser based thing that takes a while to generate all the thumbnails for the images (admittedly when the 'conversion' task finishes, this might be quicker) and it divides them all into pages showing something like 50 at a time by default. I've got some folders with hundreds of photos in and I don't want to have to click through 4/5 pages to get to the image I want. Plus who wants to look at a local folder of photos through a web page?
If it's the same as came on board the qnap, it uses imagemajick. Fair enough, until it starts to tackle >10 MB images on what is essentially a woefully underpowered pc.
Also, the gallery feature just suxors on a good day.

Got it sorted, in addition to removing the photo/media server apps, there's an option to remove the index itself and that's stopped the process.
I guess they lease/procure apps from 3rd parties and take a fee for including them in the software. HP used to be buggers for it, there's still a lot of crap on the desktop PCs we get at work, but nowhere near the amount they used to have, it'd take something like half a day to get rid of it all.
AFAIK the consumer NAS purveyors take open source, without thanks or attribution, and 'customize' it (aka fuck it up) with all kinds of half-assed, performance and stability -killing add-ons they think folks want.

I'm a bit anal about my media collection - ripped all my CDs a while back as FLAC and made sure all the album was correct. I recently started using Musicbee as a player and it pissed me off at first as it decided it was going to download what it thought I should have as album art rather than looking in the local folder for an image. I got this sorted after fiddling with the many many options it's got. :)
When it comes to films, I want a rip of the disc in high quality with the audio options configured to how I want them - you're always going to be chancing it with a download. I also get the option on whether or not to keep any extras, like audio commentary - something that's well worth it with the likes of Red Dwarf. I appreciate it'll be quicker, but a DVD takes around 1.5 hours to rip, blu-rays maybe 2, but I can leave them going during the day/overnight while I'm doing other stuff. It's not an inconvenience, just time consuming.
