AMD's 'AM' sockets can be quite confusing because you can use an AM2+ CPU in an AM2 socket, but an AM2 CPU will not work in an AM2+ socket. Meanwhile, an AM3 CPU will work in either an AM2 or an AM2+ socket! But whichever CPU you are using on whichever motherboard, you will find that the CPU socket and surrounding plastic frame are actually the same for AM2, AM2+ and AM3. Therefore if a cooler will physically fit AM2 then it will also fit AM2+ and AM3. Just bear in mind though that this does not necessarily mean it will be suitable for an AM3 CPU, because it might not be able to cool it sufficiently well.
