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.
I am deeply satisfied with the build quality and speed of shipping of the heatsink that I ordered.
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.
The shipment arrived quickly, and was well packaged. No blemishes, or bent fins. I'm extremely satisfied and will continue to purchase from this supplier.
Heavy duty little jewel!
I was surprised about the good product, and getting it so fast with a reasonable price, Thank you
Very nice extrusion. Good surface finish for mounting power devices without extra machining.
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.
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!
