I doubt mouser -- or anyone else, for that matter -- would
carry a drop-in replacement for the fan. It appears to
have been designed as *part* of the heatsink assembly
and not an "add on" (like MOST fans).
For example, the fan itself is probably about the same
size as a 40-50mm box fan. *But*, instead of moving air
axially (like a regular fan), it moves it radially
(more like a squirrel cage fan). I.e., it sits *beside*
(not on top of) the heatsink assembly and blows air
across the heatsink (instead of down through it).
It doesn't appear that the fan can be separated from the
rest of the plastic that holds it (though that plastic
assembly can be removed from the heatsink)

I'll check my mouser catalog but have a reasonably strong
feeling that they won't have anything suitable. I'd like
to find something that can pick up the mountings for the
heatsink (it doesn;t use the "clip" that many intel
CPUs use) directly.
