I dropped by the campus bookstore just now and saw two quiet machines. One is of course the Apple G4 Cube. You can hear the hard drive on it, but only barely. It's a bit of a black box though -- didn't see where I could plug in, say, a microphone. The display model had a huge (>= 24") LCD screen and played DVD's nicely (hardware decoding? software decoding?). The other is this box called Sony Vaio Sound Studio, or something like that. It looks like a regular ATX-type box but with a nicer paint job. Didn't hear any CPU fan on it, can anyone confirm this? As far as variable speed, goes, I think my Slot-1 motherboard (ASUS p3v133) supports it, since the hardware monitor (both BIOS and lm-sensors) report fluctuating fan speeds. However, I think the p3v133 doesn't have enough temperature sensors to make this feature useful. Basically the fan always spins at 4000-4500 RPM. It seems to me if I could do the same thing to my CPU fan as I did to my P/S fan - re-wire it to run at a lower voltage - both my computer and my ears would be happy. A proper temperature sensor (thermistor?) would of course be the right solution, anyone know how to build/buy/install one of these? Failing that, maybe I'll just get a resistor at Radio Shack and try patching that into the wire from the fan to the motherboard.. suggestions on this also welcome.
