I have recently made myself a nice new Shuttle SN45G PC which i am very happy with. It has the following components AMD ATHLON 2800+ (barton core) Clock speed at 2.08GHZ 512MB DDR 3200 Crucial RAM 160 GB Maxtor 7200 RPM Hard drve ATI radon 9200+ Graphics Card. Cheap CD/RW I am looking into making it silent so i can use it as a HTPC. I have looked at the problem over the last couple of days and i have worked out there are two causes of the noise. 1. The PSU 2. The ICE Heatpipe fan. I can replace the PSU with a silentX one, if no-one has any cheaper idea so it leaves the only problem. This is the ICE heatpipe Fan, Can i replace this with a different one? You kind of have to understand how this specaiil ICE technolgy works and im sure you lot all do. I have put it on its slowest settings and its still making a noise so any ideas? Any help much appreciated.
