I use the BTF-95 cooler (Butterfly, copper, looks nice and is still affordable). The cooler was also specified for much warmer (more TDP) CPUs at that time. It had a broad socket compatibility, came with mounting equipment for AMDs as well as intels. Installation was okay, though it needs some space.
B.t.w. it is cold as ice on top. Even during compiling it stays cool (but the 4850e isn't a real hothead anyway). When I touch it now (during idling most of the time) the top feels like room temperature.
So there are reserves left.
I guess that one should also be able to cool a 65W TDP Athlon2.
If you already have one that can cool a Phenom it should also be able to handle an Athlon.
Stop TCPA, stupid software patents and corrupt politicians!
