Snip: Here’s a closer look at the base plate. You can clearly see Swiftech’s Patent-Pending Diamond Pin Matrix design. One thing to note on the inner machine work… on some of the first production runs of the APOGEE CPU block, there was a problem with copper shavings being left on the inside of the block. Swiftech has now added a bead blasting process to ensure that the base plates are totally clean and free of shavings. This is why the inside of the block now has a somewhat textured finish instead of a shiny one.
