I am currently running the Taisol 092. I have come to the conclusion that Taisol iis the company maanufacturing the OEM hsf assby's for the AMD socket A processors. The 092 is basically the HSF that they ship with the 1 gig chips:therefore it works well on the Durons, and the T-Bird's that are under a gig. I have had mine running for about 2 weeks, now- my temps are: idle,87 Fahrenheit, full load:105. ( w/artic silver)
 Looking at the FOP 32, and the larger mass of the sink, I have no doubt that it would be a superior HSF for faster, hotter processors, but the Taisol will suffice for your Duron.
