Has anyone passivly cooled a Via C3 CPU? I know most of the C3's in the mini systems use passive cooling, but how well is the circulation in the box? I'm wanting to build a nearly silent router using that processor.. I hope to have the fan in the PSU the only fan in the system (micro-atx case). I did some tests with a stock AMD heatsink minus the fan. I managed to reach around 130 degrees at full load after about an half hour. -scoob8000
