Ok, so right now I've got a Barton 2500+ running at stock speeds with the same Thermaltake Volcano 7+ I had on my old Thunderbird 1Ghz. I want to push this Barton up to 2.2Ghz when I get some DDR-400 but I want to replace the volcano before doing so. Frankly, having to adjust the fan from "silent crappy cooling" to "blazingly loud, less-crappy cooling" is getting irritating. On the medium setting I'm getting about 45C, but I've seen benchmarks with the Thermaltake silent boost and the Vantec Aeroflow that promise much lower temps at a much less irritating decible level. The problem is that I can't find ANY benchmark that pits the two heatsinks against each other. Anyone got any ideas? If there's another one out there that offers better cooling at the same or better volumes, plz let me know!
