I just put my first system together and I think I bought the loudest fan on the market. The Dragon Orb 1 is appropriateley named, for although I've never seen a dragon in person, I know what one sounds like now (a high-frequency whine, sort of like a jet-engine). I'm not overclocking so I don't need the uber-fan, I just want to be able to sleep with my computer on (my roomie tells me he keeps hearing my computer out in the living-room and thinking it's the VCR rewinding a tape). I'm motivated enough to tear the motherboard out and replace the hsf post-haste. Any recomendations for a quieter solution would be appreciated. Also, I am on a somewhat limited budget (<$100 should be enough) and I'm not shelling out the cash for liquid cooling. There has to be a good-reliable-quiet-high-volume fan out there, right?
The easiest solution (with whatever HSF you purchase) would be to replace the fan with a Panaflo. These fans have a Hydro Wave bearing (liquid) and are the quietest type of fan available. Here's a typical example: <A HREF="http://www.pcmods.com/list.asp?CtgID=19" target="_new">PCMods</A>.
Orb-style HSFs are generally not the best solution for an Athlon, IMO.
