Pastall 100 PCS (8 Different Sizes) Heatsink Kit with Conductive Adhesive Tape, Aluminum Heat Sinks Cooler and Copper Heat Sink for Raspberry Pi A B B+ 2/3/4/5

The adhesive is great, and they work as well as you’d want tiny little heatsinks to.

This 100-piece assortment of heatsinks is like a tiny, metallic first-aid kit for your electronics. It's the ultimate collection for anyone who's ever worried about their precious chips spontaneously combusting. With eight different sizes, it's a bit like they're saying, "We don't know what you're overheating, but we've got you covered." I used them all over my amplifier motherboard... and now she is cool as a cucumber. These little guys are surprisingly effective. They attach easily to your components, like miniature chrome hats, and wick away heat like tiny, diligent superheroes. You might even find yourself checking on your formerly scorching devices, only to find them cool and serene, perhaps even a little smug. The sheer quantity is almost comical. 100 pieces! It's enough to cool a small server farm, or at least every Raspberry Pi you own. You'll probably end up with a lifetime supply, leading to unexpected uses. ("Honey, have you seen my earrings? Oh, wait, never mind, they're just tiny heatsinks.") If you're into DIY electronics, overclocking, or just have a general fear of things getting too hot, this set is a must-have.

Good product for a good price. It’s nice to have all the different sizes already cut and ready to go.

I love the variety and convenience

This kits is great! It comes with a wide variety of heatsinks that should have you cover from Pi Pico all the way to the Pi 5. The backing has a single sided film you need to pull off before placing it on the chipset. Just keep in mind, the adhesive is crazy strong so make sure you have steady hand as it is pain to pull it off if you mess up. For installation, I suggest you use a set of tweezers and you shouldn't have any problems. These are heat sinks for passive cooling and with active cooling for those who likes to run a external fan. The size of each heat sinks is spot on fo each chipset and it functions as describes. Though I'm just using these heatsink to help cool the Pi 4 down which is just running a MMDVM hat for digital radio.

Every install of new hardware I do I use one these heat sinks to help reduce heat on chips that get hot. Wouldn’t install anything until chips get a heat sink. Adhesive could be stronger but holds. Over time will tell the story. Nice size selection for most small chips wish kit had some 18x18mm sinks for larger chips.

What caliber of design engineer chooses a poor adhesive on such a critical part. Apparently one that hasn’t a care if the conductive heat sink happens to move against another device and shorts out your PCB ! I guarantee that this part would never be chosen for use in a consumer device or the company would have to settle endless legal claims of damage. I have to “strip” the tape off and use a “tacky” thermal paste.. ridiculous!

This is a wide selection of small heat sinks. There are quite a few different sizes, but the largest is around 1/2" (12.5mm) square and 1/4 (6mm) thick. This is a good selection for those interested in Raspberry Pi style or vintage computers. They are easy to install. To promote long term adhesion, just wipe the target chip down with alcohol and let it dry before installation. The quantity and selection makes this set a reasonably good priced kit.

I purchased these to use on IC chips in vintage electronics It's a nice little kit, with lots of size choices. I had to buy two kits as I needed more of the larger heat sinks & didn't really need many of the smaller ones They seem to be doing the job The adhesive pads aren't as sticky as I would like them to be, but they seem to be holding up for now
