Magnetite Grey Aluminum Case/Heatsink for Raspberry Pi 4
This fantastic case offers the great advantage of combining the features of a heat sink within an absolutely elegant lead-grey case. This fantastic anodized aluminum case for the Raspberry Pi 4 provides passive cooling of 10–15°C under full CPU load.
This heat sink case will not only protect your Raspberry Pi 4 but will also ensure the best possible passive cooling, as confirmed by the numerous and extensive tests carried out. It’s also the ideal case if you want absolutely silent cooling.
The case ships with a thermal pad to ensure thermal contact between the CPU and the top of the case, as well as a handy hex key and a set of hex head screws for assembly.
This case allows access to all ports, connectors, and pins on the Raspberry Pi. You can also use slim-profile HATs and pHATs (those without bulky components on the underside) with a booster header, as long as you’re careful not to short any components against the metal top of the case.

How to Assemble the Aluminium Heat Sink Case
It only takes a couple of minutes to assemble this case, as it is very straightforward. However, you must ensure that your Raspberry Pi board is switched off and unplugged before fitting it into the case.
Remove the two protective films from both sides of the thermal pad. (On one side, the film is white, whilst on the other side it is transparent and easy to overlook.) Attach the thermal pad to your Raspberry Pi’s CPU (the metal square closest to the center of the PCB), as shown in the following images.


The easiest way to position the pad correctly is to attach it to the CPU first, then to the case. Use only one thermal pad with the Raspberry Pi 4.
Place the case top in position, then, holding it firmly, flip everything over and place the bottom of the case onto the underside of your Raspberry Pi 4 board. Use the four hex screws and the key to secure the case.
Notes
- Remember that the case is metal and therefore a good conductor, so be careful of possible short circuits with other components. Make sure your Raspberry Pi 4 board is powered off and unplugged when installing it in the case.
- Remember that the case will obviously get hot during use.
- Raspberry Pi 4 board not included. It can be purchased separately.
- Dimensions: 87 x 56 x 25.5 mm
