4pcs 20mm Heatsink 20x20x4mm + pre Applied Thermal Conductive Adhesive Tape (20mmx20mmx4mm) (Copper 20mm)
0.78" x 0.78" x 0.16" / 20mm (L) x 20mm (W) x 4mm (H) copper heat sink kit is made from C1100 alloy with high thermal conductivity, durable structure stability and light weight. The heat sink engraved in vertical and horizontal grooves, that is greatly increases the heat dissipation function. This kit of heat sink comes with 20x20mm pre-applied thermal conductive adhesive tape (datasheet-8810.pdf), for easy installation and optimum heat conductivity.
4pcs 20×20 copper heatsink together with pre-applied thermal conductive adhesive tape is easy to install and efficient in heat conduction from power source. This 20mm copper heat sink kit is suitable for a variety of cooling applications. These heat sinks have profiles which are short enough to fit within standard cases.

I have a few home built 3D printers with beefy nema 17 steppers, running at 2a each. They get pretty toasty, especially at high speeds and accelerations. These copper heatsinks are a must for them, the steppers run way cooler with these compared to the other black aluminum heatsinks I had on them before, easily 10C cooler with a temp reader.

I used these for the backs of LED chips, that are 20mmx20mm.Compared to the aluminum ones, these work much better. I think aluminum only has about half of the thermal conductivity as copper, and that tracks with about how hot they get when run at the same wattage. The adhesive is solid and not coming off anytime soon.
