6000AL-Cu The 6500 is a P4 heatsink. That one lists compatibility with Socket A and 370. However, I'd advise against it, as I've found it to be an under-performing heatsink.
my bad...i just looked at the picture of it and then compared it to that from overclockers... ooops...guess i should really read...
It wouldnt have been for performance... more being quiet. Shame its the 6000, would have been cheap for the 6500.
