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

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.

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.

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

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

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.

I created a custom plex server using an laptop motherboard and I wanted to cool a few components a little. One component was an m.2 to 2.5gb lan adapter. In about an hour the speed would start to drop and using a thermal camera I discovered one chip on the adapter that was getting very hot. I stuck on a little blue heatsink and the throttling stopped. I ran a test for over 5 hours and had a stable fast connection the whole time. The little heatsink did get a little warm but it was obviously making a difference. I'll add a pic of the m.2/lan adapter with the heatsink. I later added one of the desk/cabinet ac infinity USB fans and now the system CPU fan rarely even runs. It has to be transcoding 3 or more streams before the CPU fan kicks on. I also covered the heatpipe for the CPU with little heatsinks, lol. Just for fun at first. I also thought it would look neat in the transparent case I built even though no one ever sees it.. but it has actually helped with cpu thermals much more than I expected.

I used several of these to help keep components and connectors cool on my Ham Radio Gear

Stuck a bunch on a ROKU streaming stick to help cool it down. Seems to help
