I have two coolers lying around, the 508955-001 and 624787-001 version. The 508955-001 is heavier and wider at the bottom with wider fins and visible copper heat pipes. The 624787-001 is basically a mirrored upper half of the 508955-001 - thinner fins across the board and what I assume is zinc/steel heat pipe. Any thoughts?
