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 picked up this pack to add extra cooling to a few stepper drivers and small boards on my printers and it did exactly what I needed. The heatsinks are clean and uniform with no bent fins or rough cuts. They feel solid and the surface area is good for their size. What I really liked was the inclusion of the 3M pads since they stick well and do not peel off after the parts warm up. I tested a few on motor drivers that tend to run hot and the temperature drop was noticeable once the heatsinks were added. The adhesive grabs fast but you still have a moment to shift it if you place it slightly off center. There are enough pieces in the kit to outfit more than one machine and still have spares for future projects. If you work with small electronics or want to keep your printer drivers cooler this is a simple low cost upgrade. The kit gives you a good variety of sizes and the adhesion holds up better than the cheap pads that come with a lot of other kits.

Cool (pun intended) looking heatsinks, fit the job as expected. I did not have issues with adhesives, but I guess the time will tell.

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.

No issue

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

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.

On the Creality Ender 3v2 the manufacturer undersized the heatsinks on the 2208 stepper drivers. I replaced the original heatsinks with these. Also Creality set the stepper driver voltages too hi. I turned all 4 drivers voltages down until the X-Y-Z-E motors run warm, not too hot. This fixes the problem with layer shifting. I did use heatsink thermal glue instead of using the thermal tape that are on these heatsinks. I peeled the thermal tape off, then glued these on the stepper drivers. My two Ender 3v2s are now running very well. On a side note, the Creality mainboard v4.2.7 uses these same heatsinks in black instead of blue.

I needed a slightly larger heatsink for some hot IC's. These seem to take more heat away.

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.

いつもの電子部品屋に渋々行ってヒートシンク買おうと思ったのですが、欲しいサイズが無い... そしてクソほど高い... 小さくなるほど高くなるのは世の常なんでしょうかね？ 過去に中華ヒートシンク買って痛い目見てたのですが、他のレビューも良さそうだったのでポチリ。 3Dプリンタのコントローラー用に使ってますが最高... しかも30個で900円... 1個30円でさらにサーマルテープ付き... 某電子部品屋で1つ200円でしたよ... 温度も10度近く落ちて処理落ちしないようになりました。 ヒートシンクって大事だなー ただ、数点曲がってたり表面が剥がれてましたが見えない部分なんでどうでもいいです。 状態とか気にされる方はちょっと気を付けた方がいいかも？ それでもこのクオリティでこの値段なら十分アリです。

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.

Product as described - sticker even last in very high temperatures

pretty cool, I lined them up nicely on the back plate of EVGA 3080ti where the VRAM are. (and thermal pad the pcb to backplate where VRAM sits.) I then slapped a Noctua (NF-A9 FLX) 92mm fan on it and dropped VRAM temp by 2C on max load LOL
