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

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.

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

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.

I used a couple of the 14x14x1mm shims on an RX6400. These Shims did not do much in dropping temps during heavy usage, maybe 2C to 3C however; I did notice a significant increase in how fast it cooled down going from heavy usage to idle. (note: Thermal Paste was replaced aswell) Before the card on cold boot -averaging around 45c to 50c -under load peaked at 83C and junction temp was 90c -After heavy usage and it cooling down to idle and very low usage would hover in the high 60s low 70s which i did not like seeing. -light work and continued use would stay around 67c After thermal paste and copper shims -averaging around 42C - 47C -under load peaked at 80-83C So there was not much of a huge change there -The Heavy use and then cooling down to idle at this point is where it made the wild difference. It would take less then 8 seconds to go from 83C and plunge down to 65C and then slowly taper off around high 50s and then eventually go back to high 40s! so not to shabby! The few grams made the difference in cutting time down the to fraction it was taking originally to see Temps drop down after gaming or heavy use. I think if i had added these shims under the shroud would have benefited more then near the Die because of the air contact they would have being where the fan is (the shroud is part of the heatsink). This is really not the best way to try to drop temps as i believe the type of card i have would benefit having at least 2 more flat copper pipes to really make a difference The 2nd project faired far better. I Added a Copper shim and paste to the southbridge heatsink on an old Gigabyte motherboard i was refurbishing. That had made a huge difference. Southbridge ran hot and would shutdown even with a light overclock, or i would periodically see that my computer had restarted and reset BIOS to default from a hardware failure. After the mod, that whole issue went away and my overclock has been stable ever since! I dont have a before temp. reading. For after: temps peaked around 50-55C but never went above that. idle temp saw a 22C-25C. 3rd project was a Dell Latitude 7480 where i used 5 of the 14x14 shims and one 12x12 engraved shim (i thought it was a nice touch) to try and moderate the temps for the i7 6600U. Junction TDP is 100C and i had seen it almost hit the mark Before Shims: -Fan would be on blast and almost full power -Idle - 50-56C -Load - Peaked around 94-95C average 82C -Average jumped around from 78C - 85C moderate use Thermal Throttling and would not hold the 3.2 turbo boost After Shims: -Fan does not ramp up to full blast, will turn on but is more of a mild blast. -Idle around 35C - 41C -Load Peaked at 85C Average 74C -Average temp 68C - 72C moderate use The laptop saw a huge improvement in thermals dropping -10 to -15 degrees and the system feels alittle more stable This is an inexpensive pack to get for any light to mid repairs and projects. I know this pack is geared for Raspberry Pi systems, but the sizes i was looking for were all here in this package that works great for any other project i needed them for. happy with them! the adhesives are the weak part of this. They do ok and they adhere fine but if you are needing to readjust or end up making a miscalculation on placement and need to move these, the adhesive will rip and come up or start to separate from the heatsinks. I guess that can be something to be thankful in they are forgiving in that regard but do know the fragile tape will be a little mangled. Adding thermal pads with adhesion would do a lot better then tape alone. Pick up some better thermal tape with these or for a more permanent solution, go for thermal glue

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

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.

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!

Awesome kit. Contains heat sinks of various (small) sizes for single board computers or other electronics that tend to overheat under load. Easy to install, lots of sizes and shapes to choose from.

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
