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

All to the specs worked great for our prototype design.

They work as they should, they adhere really well. Will buy again.

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

They are small and convenient heatsinks. The adhesion of the tape really only works decently when the entire surface has a flat surface with which to mate, and this is my only gripe. I have used some of these on top of 6.0W/mK thermal pads to great results as well; this is usually the route I take when I have several small parts of an uneven height in a small area that will be covered by only one heatsink. I take a razor and perform microsurgery on the thermal pad to get it cut to the various heights of the components to the heatsink can sit flat. Works like a charm. A good deal and would recommend.

Fantastic heatsinks! Only thing is dont forget to peel off the blue protective plastic coveting tape on the bottom, its a thin of plastic layer to protect the actual white thermal adhesive tape under it. After removing the blue tape, the adhesive on the actual heatsink is very sticky and seems to be pretty high quality. Just dont forget to use 91 percent isopropyl alcohol and a q tip to thoroughly clean the top of the chip youre trying to place it on to allow the best mating surface for the thermal adhesive to bond to. Try to get the position perfect the first time onto the chip or ic, otherwise it will reduce the effectiveness of the thermal glues thermal conductivity and adhesive properties if you have to reposition or remove the heatsink after it being placed onto the chip, after placing on top of your chip, apply direct downward medium force pressure on top of heatsink with your thumb, being careful to not shift or move the heatsinks position on the chip, apply this pressure for for 15 to 30 seconds to allow for a strong thermal and adhesive bond with the chip and you will be happy. Seen people complain about these heatsinks that they dont work, that they dont stick well, they most certainly do, it is just that those people probably are not installing them correctly, just figured I say something. Follow my directions and you will be happy!

Sticks well. Designed and built well. Would by again for smaller applications.

fits well and stays on my driver ICs. keeps them cool.

My 3d printer really loved it. I bet theres more uses for this. I was able to keep the temperature lower than usual for my 3D printers stepper motors.

Applied them to the circuit boards of an outdoor weather station. Nice and small, decent quality. Not sure how well the thermal tape will hold up over time but appears to be working as they should.

Cheaper packs exist, but the thermal paste on these are nice.
