12 Pcs Raspberry Pi 4 Heatsink, MazerPi Raspberry Pi Heatsink Set Copper Heatsink with 3M 8810 Thermal Pad Heatsink for Raspberry Pi 4 Model B/ 3B+/ 3B/ 2B (All Copper)

GoPro Hero 8 black would always overheat after about 20-30 minutes of shooting 4k/60 fps. I understand that this is not the intended use of this camera, but when you have kids and need to capture events, those are the kind of times you're looking at. Placing it on the camera at certain hot spots has helped to dissipate the heat to the point where I can run it inside for as long as the SD card and external battery has space and power. I haven't tried this outside in the summer yet, but am certain it will at least help.

Haven't done any hard testing but they do get hot under load so I'll assume there working fine.

Using it with rpi4 8gb overclocked 2147mhz 7/24With open cluster case and 120mm fanunder loadBefore heatsink: Between 65 - 72 degrees CelsiusWith heatsink: Between 60 - 65 degrees Celsius

I installed the heat sinks on an existing PI-4, 8gb.The temperatures are 15 degrees F lower than the original heat sinks provided.

Temperatures are the same as before installing these heatsinks. Removing the tape for the adhesive can be difficult if you have short nails but I got it off eventually. If you have fat fingers, get some tweezers and make life easier for yourselfPros:- Straightforward installation- Sized for Raspberry Pi 4- No clearance issues with the official caseCons:- Does not improve temps at all

These are solid copper heat sinks I use for my raspberry pi. Only way to go is copper in my book. Great quality.

I may have submitted a review for a kit of parts rather than heatsinks as the list from Amazon was a bit confusing to which one I was answering at the time. Darn small screens! These are just the heat sink selection and are nicely finished, no sharp edges on my lot, and the little adhesive strips exposed easily. And they alone, even without a fan, pull a bunch of heat off the chips that were hot to the touch.
