For those looking for quiet fans, I have found the Nexus PWM series 120mm to be the quietest fan for air flow yet. Moves more air then the Arctic fans with the same or lower noise level. I have one cooling an AMD x4 3ghz. I have it set to min speed of about 50% and it takes 100% load to get the cores up to the 40c level that it would take to trigger a higher speed. The fan is also clear with LED mount holes for those who want to fancy it up with lights.

OK, i finally found the time to complete a VDR PC based on the ION board.
The good news are:
- 1080p plays back smoothly with xine/vdpau
with very low CPU usage.
- sound over HDMI works.
- the streamdev-client plugin works - even with HD channels.
- the xine plugin works fine - also with HD channels and HD
recordings. I had to tweak a few config items.
The not-so-good news are:
- The fan is a bit loud and so far I have not found
a silent replacement fan.
- I originally set up the system as a diskless (nfsroot)
system, but KDE 4 (I am using OpenSuSE 11.2) performs unbearably slow, so I was forced to install a hard disk.
So, as it turns out, I do not need a DVB card in the PC (the server has 2 DVB-S cards and one DVB card). If I keep it that way, I really do not need the PCI slot, so I could use one of these passively cooled main boards http://geizhals.at/deutschland/a467665.html http://geizhals.at/deutschland/a439268.html
I currently use this (actively cooled) main board: http://geizhals.at/deutschland/a455388.html
Using a passively cooled main board would solve the fan noise problem.
I also finally setted up my ion system. I have a similar kind of passive cooled zotac that you put in your links but found out that without any cooling it's temperature get still pretty hight 60-65 celcius.
The included 4 inch fan was indeed pretty noisy, so I invested for a 8 inc fan and put that to my own made wooden case. (I first used old case from broken video, but that one had about 30 cm extra width, so I ended up making my own case)
With this 8 inch fan, the cpu and mcu temperatures are now about 40 celcius.
If you are interested, I put a picture on http://pilppa.org/home/blogs/index/1
For some reason the "--video vdpau" option for vdr-sxfe still does not work for me... (Using mandriva 2010 version of everything else except from own build vdr-1.7.10 and couple od days old xineliboutput plugin with latest fix being: Fixed generating lirc key release events) ). gdb crash log is below:
