Introducing...my XBMC HTPC (and some questions :) )

After using Windows MCE for years I recently fell in love with XBMC and after getting to know XBMC I upgraded my HTPC to get completely satisfied with my setup

My hardware:
Silverstone Grandia GD05B usb3.0 black
Asus F1A75-M mATX board
AMD A6-3500 CPU
2* 4GB Corsair memory
2* 2TB 7200RPM disks (only for DVD, HD movies and TV Shows)
1* 256GB Samsung SSD (OS)
1* 1TB (MP3, HD concerts, music videos and downloads)
Logitech Harmony Remote One

My software:
Windows 7 Ultimate SP1 (so I can also RDP to my HTPC when listening to music etc.).
XBMC 11 + HD Audio Patch (12.0 nightly builds are not too stable unfortunately )
SabNZBD

I'm using XBMC in combination with a 50" Samsung TV, Onkyo TX-NR609 receiver and Jamo S608 speakers (bi-amped).

This setup just really satisfies me and impresses (and a lot of other people ).

The only thing I need some help with are the fans in my case. I have 3* 120mm fans (came with the case) and standard AMD cooler and I want to change those. I'm looking for fans that are every quiet for my case and for my CPU. The only thing that can be a problem is that I only have ~11cm space in height for another CPU fan.

So guys (and girls)...what 120mm fans and AMD F1 CPU cooler can you advise me to use?

Thanks!

Marc.
