So there are no fans whatsoever. I have no computer case but have mounted everything directly on the wall to give it better air cicrulation. The CPU and power supply go a little hotter than they should but not overly much. The only moving-part component is currently the hard drive, but that is a very silent Seagate drive housed in a plexiglass box so it doesn't make much noise. If you don't know what to listen for you won't notice that the computer is on. The hard drive makes a very low, humming noise, and the graphics card makes a low, wheezing sound (possibly the heat pipe) when it does 3D stuff. But these sounds are almost like a person breathing so it has to be really quiet or you won't hear them. Next time I build a computer for home use I'll build my own heat dissipators, I think. If I make them really large and bulky (and with a lot of surface area of course), I should be able to cool things with no heatpipe noise at all. And if I then also use a flash drive I might be able to make the noise level undetectable. /Ragnar
