🌡️ DZS Aluminium Radiator for Raspberry Pi Review

They seem to be working fine. It's debatable that heatsinks do anything at all on the Raspberry Pi; I couldn't tell a difference of more than a degree or three, regardless of the heatsink. But every little thing helps, especially on the Pi3.

Heatsinks are fine, as is almost any piece of finned aluminum, but don't use the tape that comes with it. I received 3M 9448A acrylic based cloth tape which is a better thermal insulator than a conductor. It's a thin piece of tape, so obviously conduction of heat to the sink is good, but it's best to use a tape with better heat-conducting properties.

Heatsink Heatsink suggesting the stickers on it are particularly good although a bit difficult to peel off due to the thinness of the tape and coating. The seller will likely benefit from a few other stats for other boards, such as B.: 10 large heatsinks, 5 smaller ones for larger Raspberry Pi boards, only one larger size for smaller Pi boards, medium sizes for some Arduino boards, etc.
