      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.

      Heavy!

      Posted by Anonymous on 17th Feb 2017

      I bought several of these cut to 36 inches. These things are heavy! Obviously a quality product. The serrations were noticeable and pretty neat looking. One thing to keep in mind though, the bottom wasn't a shiny clean smooth surface, it was a bit scratched up, not a big deal but it is something to keep in mind.

      Better than I thought!

      Posted by Len Flint on 23rd Jan 2015

      Although this is a fairly small sink, a 4" section is capable of dissipating 45 watts with a temp increase of only about 25 degrees C ,in the horizontal plane, in a stagnant air area. With some air movement allowed, the temp rise was only about 15 degrees. This is going to be my "go to" heatsink in the future!
