uxcell 8 Pieces MC-200 Copper Heatsink, Self-Adhesive Memory IC Chipset Cooling Fins Heat Sink for DDR VGA, 22mmx8mmx5mm

Using these to add some mass and dissipation ability to the Legion Go’s heatsink. They work and stick well.

I got a cheap motherboard for a NAS I was building and it had bare VRMs. Those get very hot and I'm not a fan of shortening the life of components needlessly. There is only a very narrow gap to fit heatsinks and I found surprisingly difficult to source tiny heatsinks that weren't priced as if they were made of gold. These fit - These stick - They pull heat. I only needed them to fit, not fall off and short out the SAS controller and to be better than nothing. These are doing all that so 5 stars.

Wish had more and thinner fins to cool better. But needed something low profile to fit on top of Vista inside rc car

I used these for a high power VTX for one of my larger drones. I was getting video dropouts from overheating. 3 of these and I haven't had a single issue since

These are working fine on my water cooled gpu. I used some thermal glue just in case.

It's okay. It's not the best in quality; the sizes aren't very consistent and has a lot of scratches (a couple deep), but it does what it does.

Nice little copper heat sinks. They weigh more than you would think. If they were being used in mobile application I would use some kind of mechanical fasting device to secure them in place, due to their mass.

Decent quality copper
