Easycargo 40mm Heatsink Kit 40x40x11mm + 3M8810 Thermal Conductive Adhesive Tape, Cooler Aluminum Heat Sink for Cooling 3D Printer Stepper Motor TEC1-12706 Thermoelectric Peltier Module 40mmx40mmx11mm

The size is perfect for standard size stepper motors, the adhesive didn’t require any prep work and has held on upside down in temperature fluctuating chamber with no issues. I used an extra to mount to pancake stepper that is moving all the time. Still holding like a rock. My stepper motors seem to keep about 8 degrees colder during peak usage.Great gain for the price.

I put 8 of these on my DC DC battery charger in my camper van. Keeping the charger several degrees cooler than it was before. The adhesive bottoms work well. Seems like good value for the money. The small size also makes them versatile.

A great addition to any electronic device such as audio to increase heat sink surface area and enhance passive cooling or incorporate into an active cooling system.Strong adhesive. Place carefully as you will only have one shot at mounting it! Quite difficult to remove and there’s also the risk of damage to your device should you try to.

Does what it should do, works well.

Amazing for cooling 3d printer stepper motors

I used these on the power pack for my laptop. I noticed it gets extremely hot. I added 1 heatsink to each side and the temperature difference was remarkable. It was actually cool to the touch.

Exactly as expected

Not the ideal size and shape for my tab power transistors sticking up from a breadboard. But I simply peeled the back off and stuck them on with one corner pointed down, like a diamond shape. They stick well, and the transistors are running cool!
