recent order for heatsink
great product. superbly produced excellent service
Low cost, high quality
Incredibly affordable for the base thickness you get. You won't find such a tall or thick heat sink from places like amazon. Cut is high quality, very little bur is left behind.
A good heatsink, promptly shipped.
Best quality, sharp cut. Fast shipping
This heatsink is a good dissapator
One word, Beast. .....
Beautiful piece. Like a trophy. A shame to have to drill it to use it.
Excellent Quality, Affordable Heatsink
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.
A very large fin heatsink.
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.
