DGZZI Aluminum Heatsink 25X25X10mm Silicone: Efficient Cooling Solution for Electronics Review

The DGZZI Aluminum Heatsink is an excellent thermal management product. As a result of my tests, I determined that this heatsink provided efficient heat dissipation and kept the temperature of my device stable even during heavy usage. The compact size of this heatsink makes it easy to install in tight spaces. The only con is that it may not be suitable for larger devices due to its small size. Overall, a great product for any small electronic device that needs cooling.

Replaced the stock 15mm x 15mm x 10mm heatsink that came with my Pi 3 B+ kit. The 25mm hs fits comfortably on the Pi 3B+ and has enough room to fit an additional 25mm above the USB/network controller (with a little movement). A few hours later the simple software that runs it reported that it was 3 degrees lower with the same summer weather ). . Mission accomplished.

The heatsinks appear to be good enough, but the so-called "thermal pad" that they come with appears to be nothing more than high-temp glue. remove pain and appears to have no thermal properties. It still manages to conduct heat to the heatsinks, but for the best performance you should probably get your own thermal pads. Seller must amend the product listing to remove any mention of it, including thermal pads.
