  • Aluminum radiator has the advantages of beautiful appearance, light weight, good heat dissipation performance and energy saving effect.
  • The surface of good aluminum radiator is anodized to increase the corrosion resistance, abrasion resistance and appearance of the aluminum surface treatment.
  • In computers, heat sinks are used to cool central processing units or graphics processors.
  • Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as light emitting diodes (LEDs).

I returned these inefficient heat sinks & I was charged shipping fee to return. This is ridiculous for prime members. I will soon close my account.

Can't complain. The measurements shown in the listing are accurate down to the tenth of a millimeter and consistent across all 4 pieces. Certainly aluminum, a neodymium magnet has absolutely no effect at all on these. Like holding a magnet to a block of wood. And the electrical resistance across a block is zero on my meter or at least too low for my device to measure.

The extrusion is smooth and with a high aspect ratio. The base plate is decently flat and the base material is tick enough to thread a screw hole into.

Even smartphones. Mine uses 25 watt charging. My phone gets some heat when I leave it alone to charge, that's when it's getting 25W. I set two of these down on the screen, and wala it stays much cooler when charging. This will prolong the life of my phone, including the battery.

I used these to cool a peltier chip. The contact area is nice and smooth so I was able to use a minimal amount of thermal paste. I added a fan to the fins to help circulate air. Worked out great for my project.
