Yes there are problems with the Golden Orb and Durons, I know 'cause I speak from experience.
I purchased an Orb and the pressure required to install damaged my CPU. There was no visible damage, but chip no workie.
This was using the "twist-on" Orb. They have since come out with a clip-on model which I now have and it installed fine. The shop where I purchased my Orb had both models but the boxes for the two were identical. Needless to say do not use the twist-on type on your Duron.
BTW I had the cpu replaced under warranty, they no ask, I no tell, but it seems to run a bit hotter, 51c, with the Orb than with the old CoolerMaster, which my brother now has.
