This is a little off topic in that it does not have to do with using a PC as a DAW. I've got my p4b266 in an Antec Plus1080 case. It has the obvious power supply fan, two fans on the back and one on the door. It is certainly not super quiet, though no more noisier than my old IBM Aptiva 166 which appears to just have the power supply fan. We have two other PCs in the house. One is a 2.5 year old HP 600 mhz which I would call noisy. So noisy that we had them replace the fan. It is a little quieter but still mildly annoying. It is now sitting on the floor, under a table, which helps. The other PC is a 6 month old Dell 1.7ghz. You have to stick your head right up to it to determine if it is even running. It is so quiet! I'm not even considering using a Dell for a DAW. I need to get a new PC for my in-laws and am curious about how Dell is able to have such a quiet machine. Question: - do you think that Dell has discovered some super cooling technique that the other manufacturers have not, or could Dell just be running their machines hotter that our Asus machines?
