3D Printer Heatsink Kit + Thermal Conductive Adhesive Tape, Cooler Heat Sink Cooling TMC2130 TMC2100 A4988 DRV8825 TMC2208 Stepper Motor Driver Module (22pcs)

The adhesive is useless. I had to spend time cleaning it off so I could put actual thermal tape on these to be able to use them.

These are great for chanzon 3w leds but you cant run them at full power these are tiny keep thaf in mind i just like them because they are the only heat sink that will fit on a 6 pin chanzon RGB i also have one on a raspi and it gets a lil toasty but is overall good.

I have no idea how well the adhesive transfers heat, but nothing has burnt up. They stayed stuck.

Did there job. Let me make my Ender 5 Plus a true dual Z-Axis printer.
