100 Pcs Raspberry Pi 4 Heatsink, MazerPi Raspberry Pi Heatsink Set Aluminum Heatsink with 3M 8810 Thermal Pad Copper Heatsink for Raspberry Pi 4 Model B/ 3B+/ 3B/ 2B

These heat sinks work well - nice assortment of sizes good for various projects.Remember - heat is the enemy of electronics - keep them as cool as possible and they will last a long time.

Good value for under $12.78 and it works well. I put these on MSI motherboard chips and everything that got hot. Used about 13 of them and reduced temperature by 8 to 12 degrees Fahrenheit.

I had used these to save an old Roku that was overheating.It still gets a bit warm, but no more overheating warnings that cause it to shut down.

Good product but more pieces of certain heatsinks needed ( copper plate, 20*20 heatsinks) for technicians

You can’t beat the price on these. I use them to cool my Bitaxe PCBs but they would work for any small electronics. I use these all the time and would reorder in a heartbeat.

All OK

Nice box of heatsinks, what you see is what you get!

I used just about every one of these to give some surface area to a rounded surface for active cooling.It takes forever to peel off all those little plastic covers, but none of the pre-prepared thermal stickers have come loose after a few months, so i can't complain!And for a hundred pieces, i think this is a pretty good price.
