I just put together a computer with a Volcano II, and the damn thing vibrates too!!! It vibrates so much, the whole case shakes!! Its really annoying because it's making a low rumbling noise. I ordered another fan so I hope that fixes the problem (the new fan is a Sunon, 60x25mm, 23cfm). By the way, what kind of temps are people getting with their Volcano II?? I have a Duron 750, and its running about 39 C right now according to MBM. Thats with the crappy fan, and the defult TIM. When I get the new fan, I'm going to take the whole thing off, and apply some Arctic Silver II. With that set up, could I reach 1 ghz with my Duron 750? Or do I need a better heatsink and fan?
