The new Raspberry Pi4 gets hot, really hot. As a fan (no pun intended) of passive cooling I decided to replace my gay acrylic case with a super finely aluminum machined unit from Germany. The whole concoction works as a heatsink and is, obviously, fanless and completely silent. Hopefully the system won’t throttle anymore at load.
This is the fist Pi you can pretty much use a teeny-weeny little Linux desktop computer, a really cool one at that..(even has dual display support).
