      Good all around heatsink

      Posted by Jonathan Shaull on 2nd Dec 2022

      Dimensions are just about right, serrations really does help to get the heat off it. Unfortunately the heatsink I received had a "bowed" sink base (not flat) resulting in +/-.010" deviation from the middle to the edge. Fortunately I did not need the base to be completely flat for this particular application.

      My heat sink purchase

      Posted by Gerhard Juderjahn on 6th May 2021

      Excellent product. Safely packaged. Enough styrofoam to make a boat. Took a while to remove the item it was that well protected. Thank you very much.
