heat sink deficiencies
All 4 of the heatsinks were warped, not flat, by over 1/8" and not going to be useable for my project.
12" Wide Aluminum Heatsink
Using this to cool two ESC for a electric off-road bike. Price was very good compared to anywhere else. Very high quality heat sink with a nice base width for drilling/tapping. Super happy with purchase and would recommend. Comes with "warning sharp edges" label - they do mean it. Be careful!
Very pleased with product, well built and most importantly very reasonable price. I will continue to purchase all of my heat sink needs exclusively from HeatsinkUSA. Sincerely Jeffrey Beckman Aradia HiFi LLC USA
12.000" WIDE EXTRUDED ALUMINUM HEATSINK
Fit and finish was great. We will be ordering from them again. Good quality at a good price.
Looks like a quality product. I would give a 5 star, but have not put it into service yet. I especially like the C/W dissipation rating that you give on each product.
Just the right thing.
This heat sink turned out to be just the right solution for my project. 12" wide is not readily available, so this was a great find. Quality is top notch too.
Heatsink arrived as promised
I had no problem getting the size and type of heatsink. It arrived on time and only required a quick cleaning before being installed. We have no problem ordering again!
clean cut, no scratches. Good for aesthetically-demanding work.
Nice extrusion, heat sink was free of defects, warp and uniform density! Shipping was fast and packed well. I ordered a section of this to use as a 100w led heat sink, have a few of the leds and needed to test different sizes to experiment with different fans and surface area for thermal management. Will order more as I build more, and keep some in stock for future projects! They look the will do excellent for any through transistor based heat sinks. The heat sink machined well and threaded easily. Next set for the leds or projects I may have them machine the holes for me.
