Yeah I know exactly what you mean. I had one of those on my 1.4 Thunderbird, and was once talking to someone on the phone when she asked me who was vaccuuming! I had to explain to her that it was my computer, which was across the room from where I was. This past Christmas I replaced it with an Alpha PAL 8045 heatsink and a Panaflo L1A fan, and have been extremely pleased. You can barely hear those things.
