Easycargo 30pcs 3D Printer Heatsink Kit + 3M 8810 Thermal Adhesive Tape, Anodized Aluminum Heatsink 3D Printer Cooler for Cooling TMC2130 TMC2100 A4988 DRV8825 TMC2208 Stepper Motor Driver Module

I'm using a couple in an electronics project to cool the controller IC on a couple buck converters. For my application I removed the thermal tape and set them in place with some JB Weld epoxy. I did lightly sand the heat sink and the IC both for good adhesion. And yes I know that they're permanently applied, which is what I wanted. No fear of the thermal tape letting go. The controllers now run close to 12 degrees F cooler. So they work for me. The part I'm using these on is permanently soldered in place. Both the part and heat sink are inexpensive enough not to worry about replacement.

Great inexpensive way to sink heat from small IC's. I use these mostly for stepper controllers which come with terrible little sinks. Depending on your application, using these allows me to use convection for cooling instead of active systems -- simplifies projects when you don't need to monitor temp and PWM a fan. Definitely pay for themselves.

Put these on my VCMs on my asrock motherboard, dropped the teps by 6c.Have a 120mm fan pulling air across them, can’t ever have to much cooling.And they look good!

Other than the "sticker" on the back meant to hold these items on your hot component, these are small, aluminum, blue and they do what they're supposed to do. They move heat.Replace the sticker backing with proper thermal adhesive paste.

They work great, used in my motherboard VRM. Keeps them a lot Cooler, and the preinstalled Adhesive works great, and doesn’t make a mess. Would buy again

Just what it's advertised as. I like the extra thoughtfulness of putting little tabs on the patch covers.

The adhesive isn't the best, but good heat dissipation.

Easy to apply and you can begin to reduce heat on your component immediately.

Used to add some degree of cooling to a bare motherboard VRM . Easy to install.....and they get very hot so they are obviously working well. The thermal tape is already pre-applied to each heatsink so no cutting to do. Make sure you press them firmly down and hold them for a while to make sure they stay stuck on! Nice colour too.

ma fanno il loro dovere. l'adesivo non è il massimo come aderenza, non ho potuto "misurare" la reale efficienza termica in quanto non ho gli strumenti adatti. colore molto bello (nel caso interessasse!!!) . peccato costino troppo, ma per volerli in fretta, tocca spendere!

Buen disipador para componentes con encapsulado igual o similar al TO220 que se pueden calentar en exceso si el tiempo de funcionamiento es prolongado, tanto en circuitos convencionales, como en impresoras 3D, alimentadores de modulos laser...etc. Altamente recomendado y eficiente.

Quantity and condition excellent. Stick and stay well on chip (i used them on DRV8825), until now, stayed solidly on chip working at moderate heat. Easy to prepare and install (removing the adhesive protector).

Ottimo materiale.. Per adesioni perfette ai chip pulire bene con alcol isopropyl la superficie, sennò si stacca subito
