Aluminum Heatsink Case for Raspberry Pi 4 - Obsidian Black

Why use a heatsink and a case, when you can use a heatsink case?! This black, anodized aluminum case for the Raspberry Pi 4 will give you 10-15°C of passive cooling under a full CPU load. This case is great for situations where you want completely silent cooling, like home media centers.

It comes with a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen Key and set of hex bolts to attach the case together.

The case gives you access to all of the ports, pins, and connectors. You can just about get away with using low-profile HATs and pHATs (those without bulky components on the underside) using one of our tall headers, but be extremely careful not to short any components on the metal top case!

  • Thermal Tape
  • Anodized Aluminum top and bottom case in Black
  • Heatsink fins
  • Thermal pad
  • Hex bolts and Allen Key included
  • Access to all ports, pins, and connectors
  • Compatible with Raspberry Pi 4

  • Do WiFi and Bluetooth work when using this metal case?

    • I haven't had issues, but my WiFi router and keyboard are practically next to the Pi (Router: < 10' and Keyboard: < 1'). At greater distances, you may notice changes in signal propagation due to the metal enclosure (i.e. the signal strength may peak and dip in different areas compared to without the case/heat sink).

  • After installing the PRT-15773 aluminum case on the Pi 4 and mounting everything on the back of the 7 " LCD display I found that the display ribbon cable would not fit into the MIPI DSI display connector because a part of the casting, a thin aluminum bar' was right on top of the compression fitting and it wouldn't allow it to be raised to accept the cable. I had to take everything apart to get the top cover off. Using a small die grinder I removed enough product to get the ribbon cable to clamp down in the display connector. Your product fits good, does a good job of cooling with the help of a small 5v. axial fan, BUT, to get to that point was very frustrating.

    • Great feedback for other users. Unfortunately, we didn't make the assembly guide. My guess is that the design was intended for the ribbon cable to be attached to the connector on the Pi 4 first, and then fed through the slot, before the case is fully assembled. I don't have one lying around to confirm, but that would be my "throws out the instruction manual" intuition.

Works like a charm after a little surgery

The case as received did not allow the video cable to be inserted into the connector on the Pi 4. The aluminum cross bar had to be cut out and both fins on the left and right off the connection had to be notched out also. With the addition of a 5 V. 2" sq. fan mounted on the top and a silicon rectifier diode in series in a power lead to lower the operating voltage the whole assembly is almost whisper quiet and only 6 deg. above ambient temp. !! I can supply a photo of the surgery result in required.
