Allows heatsink fan to mount your processor
properly, reducing the risk of a crushed core. Anodized Aluminum
shim for higher quality and tolerances. AMD anodized shims go
through four manufacturing processes before they are anodized,
so they don't conduct electricity. They fit ALL AMD Socket A
based processor cores, including Athlon, Duron, Palomino, Morgan,
and Spitfire. CPU spacers help preventing the cracking of CPU
cores while installing the heatsink, and help distribute weight
evenly over the core surface. They can be viewed as cheap insurance
for overclockers who change cooling solutions frequently.
