well...... like i said, it's either the CPU or VGA fan that's relatively loud. the case fans probably WOULD be loud..... but the fan controller on the front of my case practically cuts off 2/3 of the fan speed.... so if i had my 80mm fans hooked up, instead of spinning at their average of 3,000 rpm's, it's only spinning around 900-1000. and in theory... if it's 30db at 3000 rpm's, it should, in theory, only be around 10db at 1,000 rpm's. Hope i get an e-mail soon from MGE/XG about the specs for the 92mm fans so i know what THEIR average speed is, how much air they move, and their loudness. As for the case's position, i currently have it sitting on a small wood table.... probably about a foot and a half tall table. used to have it on the floor, but got tired of cleanin all the dust from the mesh panel. GOD was that a dust magnet.
It could very well be the CPU fan...... what speed does the A64 stock fan usually run at? like 3,000-ish rpm's?
