Aluminum heatsink for passive cooling of the Raspberry Pi processor.
The aluminum passive heatsink increases the area of the Raspberry Pi passive cooling processor, which cools it more efficiently. By streamlining cooling, possible overheating and underclocking of the processor is delayed.
Note: At its height, this heatsink can collide with some add-on modules! A minor collision can be solved by raising the spacers, e.g. using extra mothers.
