Spire 5E32B3 Heatsink Review

Following in the footsteps of the Spire 5E30B3, the 5E32B3 boasts the same general extrusion design, but with one twist. Where the original 5E34B3 had a copper inlayed base, and the '30' model had a seamless aluminum fin, the '32' model has multiple cross cuts. The copper base is of course absent, and the cross cuts only number six, but will these differences influence the performance of this all-in-one heatsink from Spire?

With so many similarities between the three models, the '32' model we are looking at currently is going to be hard pressed to differentiate itself visually, let alone on the temperature test platform.
