The shim is a simple little piece
of anodized aluminum that sits on top of your processor which means
that when you install a heatsink you are not going to crush or chip
your core. Now let me tell you that once you have chipped a core
and your lucky that it still works you worry about replacing the
heatsink (trust me I know) then this is for you.
Right lets wrap this up.
If you like your processor then get one of these as they are worth
it as they give you the confidence when changing heatsinks.
None (That I can think of).
Does not decrease temperature.
I would like to give special
thanks to Andy from Case-Sensitive
for the sample.
