This heatsink is a good dissapator
One word, Beast. .....
Beautiful piece. Like a trophy. A shame to have to drill it to use it.
I've struggled for years looking through the big electronics outfitters for heatsinks to fit my parts. I've always had to end up cutting into expensive anodized aluminum heatsinks to get them to properly fit to my parts. This 3.945" heatsink is perfect. It came cut to my length specifications very quickly. The machining is precise and the material is of high quality. (Note, the aluminum is bare stock, non-anodized). These are perfect for rapid prototyping or small quantity runs.
This large sink was cut very straight, and the bottom surface was quite flat. I only had to do a minimum of fine sanding to get an almost mirror finish. I'm testing a 4" piece with a 45 watt LED COB and in stagnant air it's temp only went up to 55 degrees C, with a small breeze it dropped back down to just above ambient. These tests were in the less than desirable horizontal plane.
Incredible price for a very heavy duty heatsink. Very fast shipping. Will buy from again.
This was a perfect fit for our lighting project and the price was better than an overseas vendor. Great to do business here in the USA! Look foreword to a long term friendship!
The cuts were very good quality, the base was very flat, and the finish good. I would definitely order from again!
I used two of this style for an amplifier project and was impressed with the beautiful finish, perfect cuts and quick shipping. They arrived at my door perfectly due to being well packed for shipping. I'll never again resort to the inferior quality, questionable packing and poor value items offered by foreign vendors on ebay. Thanks H-USA for accommodating hobbyists like me.
