thanks! didnt know that, that will help expand my search.
The one HSF I picked doesnt seem to be for sale anywhere, which sucks.
Yes AM2, AM2+, AM3, AM3+ all use the same socket form factor. On the AM3+ boards I've noticed that the socket 940 bracket has been changed to eliminate some of the plastic on the sides, but it still works the same.
I would take a look at a few of the Scythe fans to find something available. All the 3R systems coolers are extremely rare to find, I think they folded or supply European markets or whatever.
