Raspberry Pi Compatible
This precision metal heatsink case is so well made; it really needs to be marvelled at.
It consists of two machined halves, one ½ fitted with two tiny heat extraction fans. Metal pads (part of the upper fan heatsink) are meant to touch the top of the processors to draw heat directly from them via thermal pads supplied. There is no better way to do this. The fans draw heat away from the pads.
The Raspberry Pi® 4 can run hot at high processing speeds and this unit is the ideal way to fix this. The Pi 4 basically clamps inside the heatsink, leaving all connections free to connect to the outside world. Basically is the same foot print of the Pi 4.
