What do you guys think of this HSF? Has anyone had any experience with it? I've looked at a couple of reviews, but they didn't say what kind of processors it could cool, and to what temperature idle/load. Just says socket A. This must be a very good heatsink, being all copper, I imagine. I want it to adaquately cool my AthlonXP 2000+ and maybe let me do a bit of overclocking, say to 2200+ level.
