I am thinking about replacing a Chrom ORB on an overclocked Duron (650 @ 800MHz) so that I can push the multipler to 8.5x or 9.0x rather than the 8.0x I am at right now. However, I want something QUIET. Are either of the two coolers in the subject line (Volcano II or Tailsol CGK-742092) good options. I have read the reviews and they seem like they might be o.k., but I want feedback from others who use them regularly. Remember, quiet is good, but cool is too. FWIW, I am currently leaning towards the Taisol unit with either a Sunon 26CFM fan or a Sanyo Denki 19.1 CFM fan in place of the factory fan.
