Packaging for this cooler rates it as being effective for Athlon processors up to 1.5GHz. I really don't think that I would use it on a clock speed of anything over the 1333 that I tested it at. Also consider that I have about 170-CFM airflow going through my case and you'll see why I am hesitant in using it on higher speeds.
While the lightweight design and quiet operation is a very nice change of pace, the overall goal here is cooling. This HSF will work just fine on a Duron system since it doesn't put out as much heat, but if you're running a high-end T-Bird system, then you might want to look for a more effective cooling solution.
Bottom Line...For machines that aren't apt to create a lot of heat, then you can use this lightweight cooler with confidence. For faster systems, look elsewhere.
