Ok, thanks to everyone on the forum and to EdNG for specific advice, I have now got a system that I am more than happy with acoustically.
Now it is in no way what you would call silent, but is certainly quiet. I can hear all manner of sounds that I could never pick out before
Anyway, what I want to know is what temps should I be aiming for, or indeed getting?? I have had a look around and my system temp does seem quite high, but given spec I am not sure if it is acceptable/expected... The 60G may be leaving the system soon BTW
Spec is
Thermaltake Tsuanami case
DFI Lanparty II Ultra RevB
XP3200 Proc
2x512mb Corsair TwinX XMS Pro PC3200
Sapphire ATI9600Pro
60G Maxtor ATA133
2x120G Maxtor SATA150
200G Maxtor SATA150
