True, it is wide! Couldn't use in a Minuet with an Asrock Socket 775 mobo, but could with an Asrock AM2 mobo (new system build for my sister-in-law). Models definitely matter.the big shuriken is not the one you want, it's low profile but extremely wide
the shuriken rev b is roughly the same size as a the stock AMD phenom ii x4 BE cooler, good size..
