40PCS Raspberry Pi Heatsink Kit High Performance Aluminum Heatsink for Raspberry Pi B B+ 2 and 3, Heatsink Copper Pad Shims, with Thermal Conductive Adhesive Tape

I actually bought this for my Radeon RX 5700 XT because I am watercooling the card with a core-only waterblock, and needed heatsinks for the VRAM/VRMs and this kit worked perfectly and was much cheaper than Vram heatsinks alone sold by other suppliers.My only complaint is about the black 3M adhesive on the copper shims, I was planning to use them to add mass to the aluminum heatsinks but the adhesive was absolute garbage and did not stick to my GDDR6 modules once they warmed up, despite the fact I cleaned them very well with isopropanol. However, the white thermal adhesive on the aluminum sinks is very good.For the price there is nothing better, however, these heatsinks don't have a lot of mass, so if you're using them to cool parts with higher wattage parts than seen in a Raspberry Pie, you're going to want airflow over the heatsinks.Here are the results from my card with and without airflow over the heatsinks:Without airflow:VRM: 82c | Mem VRM1: 78c | Mem VRM2: 76c | GDDR6: 94cWith a medium speed 120mm fan blowing over the card:VRM: 72c | Mem VRM1: 61c | Mem VRM2: 59c | GDDR6: 79cThe results with airflow are very near those of AIB cards with large aircooled heatsinks, so this solution works excellently.

Great little heat-sinks and copper shims. I used these with my Raspberry PI and a travel router I use in my Jeep to keep the temps down. I also found these useful on the SOC in my 3D printer that kept overheating. Handy set, strongly recommended!

These work well to dissipate heat from IC chips on a Raspberry Pi. They are well made and are easy to install.

Alot of cute little heat sinks for cheap, you'll never need more of them. Good quality!

Great assortment at a reasonable price. Heat sinks will help in light-duty cases.Under a continuous load, external cooling (fan) may be required. Finned heat sinks will then assist in quickly drawing heat away, for dissipation by the fan.

Does not include thermal tape!!! It's high temp double sided tape. So basically using these heatsinks without changing the tape, they would be useless, probably make something overheat.

I actually use these on things like converter boxes for older game systems. A lot of them have chips that run hot and its cheaper to heat sink them long run the replaced them for 30 bucks a pop if they burn out.

This is a great kit if you use lots of SBCs like I do. Quickly grab the ones you need to keep your boards cooler.
