I have recently upgraded to the SilentX 250W PSU and although it is really quiet, is there any chance I could get it quieter with some different 40mm fans, or even just use 1 fan. Will this thing overheat?

The fans Im thinking of using are the ADDA or the Moomi, which are both quieter than the included delta 26dba fans. Heres the link: http://www.ultim8pc.co.uk/index.asp?...products&idd=4

Which fan would be better?

Thanks Guys!
