Here is my system:
PIV 2.4c @ 3GHz with a Zalman CNPS7000AlCu at lowest speed
Abit IS7 with passive heatsink on the NB
9800 Pro 256 with ATi Silencer 3 slowed down with a fanmate at lowest
40Gb Barracuda IV and 120Gb Barracuda V in their standard removable bays.
All that stuff lives inside a Chieftec Midi Server BX-00 equipped with two Arctic Fan Pro TC's @ 8volts.
PSU is a HEC 450W model with a Papst 8412NGL in it.
I have already cut out all fan grilles and covered every panel with foam and that heavy black stuff. Dunno what it is in english
You know the stuff that reduces vibrations. I've also made a duct for the PSU to draw in cool air through the 5.25" bays.
My temps are just ridiculous.. System temp is around 45C and CPU temp varies between 65 and 70 while folding. Not that great but I don't mind as long as my system is silent. But it isn't!
My system still isn't quiet enough to sleep right next to and I'm a bit unsure about what to do next. Maybe I should change all fans to Panaflo's? Maybe get rid of the 80mm case fans and fit in a 120mm fan instead? I could make hole in the top panel and mount it there.
The noise is a low hum, propably from air turbulence or something similar and also some whirring noise. Im not sure what cases that. Maybe it comes from the drives?
Any advice is more than welcome.. I want to get this thing running 24/7 even when I'm home
