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

This fits perfectly, looks great, and feels very durable. No fans, so it remains quiet. It was a little difficult to assemble myself and it didn't come with any instructions but finally figured it out.

TL;DR: Excellent case for the money, great performance for a simple Home Assistant dashboard, and silent. Use Case: I am currently using a Raspberry Pi to run a Home Assistant dashboard in my office. I was using a different heatsink with a small fan. The fan would turn on periodically throughout the day and became quite distracting for the few degrees improvement it caused, compared to if it stayed off entirely. I experimented with a handful of cases and heatsinks until I eventually landed on this item. Wow, to say the least. It brought my temperatures down from 55-60 to 35-40. All of this without the use of a fan. No complaints and I'm glad I landed on this product. Build Quality: Feels sturdy and no complaints. The paint has some blemishes, but nothing that detracts overall from its look and performance. The product does come with a copper plate for covering the CPU. Per the instructions provided, I applied thermal paste on both sides of the copper plate and then only put the smaller thermal pads over the three other chips. Performance: Excellent. The CPU temperatures exceeded my expectations and it's silent. The entire case is made out of metal, so the case does transfer heat from the Raspberry Pi. For my use case, this isn't a problem. It's just slightly warm to the touch, and still cooler than any laptop bottom would be after a few hours of use.

This case fits PERFECTLY for a typical Raspberry Pi 4B project. Please note you won't fit any hats or other add-ons in there, but it looks great, and works just fine. The SD card can be a little tricky to pull out if you don't have needle nose or tweezers, but you still have access, at least. Zero fan, so ZERO noise with the passive cooling options. It's easy enough to install onto your pi, but getting the thermal pads onto your pi itself is the tricky part. I'm not sure about what other models fit, but the 4B is perfectly compatible.

It's a fine little kit, and it is priced right. I used the included copper shim and some Arctic Silver instead of the thermal pad for the CPU. It seems to have the right amount of squish on the thermal interfaces to keep everything held together and smoosh things out appropriately. All of the thermal pads (there are two sets of 4) were cut to the right shapes, and had protective plastic on both sides which must be removed for optimal performance. One extra screw is included, along with an Allen key for tightening the screws. It cools the CPU, the RAM, the PMIC, and the USB 3 hub chip. No provision is included for cooling the Wifi chip, but none is needed or useful (and on the Pi4's PCB, the metal can covering the wifi chip doesn't actually touch anything that gets warm anyway -- there is nothing to cool here, by nature of the Pi4's design. The can improves RF interference and light sensitivity vs the Pi3B's design, which used a similar chip but as a bare unprotected silicon die). I wanted a better cooling solution for a Pi4 (I'm going on a adventure that is going to include using a Raspberry Pi on battery power while camping in the Florida sun), and I'm allergic to using noisy fans for such low-power applications. This will work great: It uses zero energy and offers wonderful thermal dissipation -- more than plenty to dump the Pi4's maximum heat output of around 6.4 Watts. In its present duty, running Kodi with LibreElec on the living room TV: It works fine. No issues. Reported temperatures while watching a film in a 68-degree room with minimal airflow are around a very-chill 31C, which is 49 degrees below the throttle temperature (and 54 degrees below the maximum allowable operating temperature) of the Pi4. I could overlock it and put the hammer down, but meh: Provisions are made for running the GPIO out with a 40-pin ribbon cable, if tinkering is in order. The finish is a nice, semi-matte black. It was consistent on the unit I ordered. One star deducted because the screws were more difficult to get started than I anticipated. It's a little bit unnerving holding the case closed with one hand (to keep the thermal interfaces where they need to be) and starting screws with my other hand. A little bit of a chamfer would completely resolve this issue, but I shouldn't have to add that myself. It would also be more-ideal if the aluminum posts molded into the top-half of the case were unpainted where they contact the parts being cooled. They're beefy and solid aluminum, and that's quite good, but the main goal of a case like this is to conduct heat and paint gets in the way of that goal.

It's a decent case, but it still gets quite hot to the touch using just the heat sinks. I haven't had an overheating or performance issues, but I just don't like how hot the outside of the case still gets. I do like that it's fan-less, so it's definitely very quiet. Other than that, the case looks and the Rasp Pi 5 fits perfectly.

I have a Pi 4b that is in here running Pi-Hole, and it runs great with this case. Temperatures are under control, and it doesn't have a fan spinning and grabbing dust. Great product, I am considering ordering another RPI!

You need this case! I have two pi 4's and have been using cases with fans. There's always a background noise and it got on my nerves. After reading some reviews about this case, I decided to give it a try and it was a great decision. I ended up getting two of them. Very easy to assemble and everything fits perfectly. I used the copper heatsink and you will need to purchase some heat sink compound for that it is not included in the kit. I also added some rubber feet on the bottom because the pi sits on the desk and the case gets a little bit warm and I don't want to ruin my wood desk. Also because it keeps it off of the flat surface, you get better circulation around the case to keep things cooler. When it's running, you will feel the case is warm. However, temperature reading of the processor averages around 40 degrees C and that is about the same as if I were using a fan. I highly recommend you get this case. Also no worries about the fan breaking down because it's just a matter of time for that happens. Yes, you will need some needle nose pliers to take out the SD card but overall that's not on deal breaker.

Very easy to assemble and built with quality. I chose to use the thermal pads and it's barely even warm after 24 hours of use. Built to last meaning it's extremely durable. Cooling has been excellent and it's small enough you can put it out of the way from prying eyes. So far it's definitely exceeded my expectations. Visually it looks pretty cool also. I had mine completely assembled within 3- 5 minutes and I have zero experience with Pi hardware. Yes, it's truly that easy.

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.

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.
