Geekworm Heavy Duty Passive Cooling Aluminum Case for Raspberry Pi 4 (P173)

Bought this for a Pi 4 running ADS-B. Almost as effective at cooling as a case fan but obviously silent. Easy to mount, nice and sturdy feel and really does keep the Pi at an acceptable operating temperature.

I was sceptical about this just being heat-soaked after time but it really works. I used the thermal pads to cover the parts on the Pi and it's doing a great job. Running stress for ~10 minutes and it kept the pi temps very reasonable (upto 54C when the pi can operate higher than that). Running a compile on it for some connected ESPHome kit and the temps are sitting at 40-45C. It's solid, sturdy, looks great, easy to assemble and not overly expensive. Doesn't cause issue with any connections. Good bit of kit

Excellent. Temperatures 10 degrees down from standard case. Easy installation. Looks great.

I am trying Windows 10 (perhaps 11) on the Pi4 and needed a better cooling solution than "none". In summary, for the price (fulfilled by AZ not China) is OK and the quality is OK. I do not like fans (noise, dust build-up, etc.) and Windows does not really have support for Pi fans (variable speed based on CPU temperature) + WiFi has no driver - thus I was not missing anything by using an all-metal enclosure. The quality is OK, very thin paint so don't bash it as it easily scratched. The screws need a bit of grease to assemble. You will need thermal grease if you're going to be use the copper shim (recommended) rather than thermal pad. SD card is a bit hard to insert/remove but then many cases are worse. In any case for Windows you want an external USB3 SSD thus not really an issue. But could be better. In use, it seems to be OK, getting warm (thus good transfer of heat) but still needs to be in a well-ventilated position. In any case it does work, even overclocking the Pi 4 to 2GHz is stable in Windows 10 Arm64. All in all, there are sleeker cases available (Flirc, Argon, etc.) but at almost 2x the cost most times. If you can get one of those, please do. Otherwise this is not bad for just over 10 quid. You can get lots of these direct from China for less but then you need to wait a few weeks. YMMV.

I have a similar case to this one but this one seems chunkier and heavier which is ideal. I didnt want any fan on this one and I think this case will provide enough area and fins to get rid of the heat. Without being crazy about it, its hard to see what else anyone can do more to get rid of the heat without using a fan. The board fits in perfectly as do all of the connector holes. The two halves fit perfectly too with a near invisible join. It comes with a set of heat pads to connect the CPU & chips to the case. Personally I find these easy to fit but people seem to have trouble with them. You take off one side peel plastic then fit to chip then peel off the other side using tweezers. Dont try to do both before fitting. Not much else to say. Its has slots in the side for the ribbon cable access to IO pins or camera / DVI ports and even a couple of small holes to see the status LEDs. If I didnt need to have easy access to IO pins then I would buy this one again as a first choice. If you need easy access to IO pins then the other similar ones with the open IO area might be the better choice.

The Geekworm P173 case is an all aluminium, solid weighty simple case that offers a passive cooling design. It seems well made and of good quality. Assembly was easy, the smaller thermal pads were a bit fiddly for my fat fingers so I needed to use plastic tweezers though. I used the copper shim on the processor since I had some thermal paste on hand. Everything lines up well and the case goes together nicely with the bolts. With the RPi4B running at 2.1GHz the temperature was 61⁰C under a full load for 30 minutes, a reduction of 10⁰C compared to the old case with a fan I was using. As this case uses passive cooling there's no annoying fan noise unlike my old case. A few negatives. The case doesn't have rubber feet sadly, so it does slide around on the desk etc. Easy enough to put some on, but would of been nice if they were included. Probably due to the case being all aluminium it appears to reduce wireless performance a little, my bluetooth keyboard occasionally lags or the have the occasional key repeat which never happened with my old plastic case.

I have a home assistant set up for my father in law which uses a pi4 to do a few limited things. It works very well, but the old case had a fan, which started to wear out. I looked for a silent, passive case and found this. Nice easy to fit and seems to be doing a very good job in keeping the cpu at a reasonable temperature. It's also a bit of a solid block of metal which is strangely reassuring that it will do its job,. In any case, I'm now happy that it will be noise free and everything will work just fine until the pi4 dies - which hopefully it won't!

I wanted to set up a network-attached media centre/surfing box for under the TV with as small a footprint as possible built around a 2GB Pi4B running Raspberry Pi OS 64-bit and KODI, and this case turned out to be the ideal solution. As I was planning on overclocking the Pi4 as far as was sensibly possible, I used the included copper shim for the SOC with Thermal Grizzly Kryonaut applied to both sides. I can now run the Pi4 at 2.3GHz ARM and 850MHz GPU speeds with temperatures never exceeding 35°C above ambient even under heavy loads. Idle temperature sits around 15°C above ambient. To say that I'm impressed would be an understatement as this is being achieved with entirely passive cooling. It looks great too. Highly recommended!

The default temperature of my rasberri by was about 70 degrees celsius. Any serious computation raised it to 85. Now, I can download files at 45MB per second without reaching 50 degrees. This is not a fake review. I really love this product. The case itself is sturdy, the packaging is small and useful. They even include an extra set of thermal pads! Really great stuff

Excellent refroidissement. Test sur Raspberry Pi 4B avec "stress-ng" : Avant de lancer, température idle à 35 °C, Après 5 minutes de stress-ng : ça ne dépasse pas les 40 °C. Je recommande, ça vaut largement mieux qu'un ventilateur et en plus sans bruit.

Solid look, physical protection of my RPi 4B, good fitting of heat sink, getting a little hot though. Using it after removing case with fan because it became too noisy.

Very good product and delivered in short time outside USA. The CPU temperature at a heavy operating load with this heat sink passive case almost reach 52° for an ambient temperature of 30°. The case is somewhat heavy than I have expected which indicates that it is fabricated from heavy metal almost iron or alumenum. Just you can set the case vertically to dissipate more heat than horizontally. Finally, I have noticed that the WiFi signal became weaker especially in the 5GHz band, however the 2.4GHz one still received with good levels.
