508955-001 vs 624787-001 cooler, which one is better?

[Adephx]

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?

Hi,

The mentioned spare (508955-001) is used in BL460 G6/G7 server and Spare (624787-001) is used in BL 460 G7 only. The heat pipe material cannot be revelealed as it is company confidential.

I work for HPE.
