for Raspberry Pi 3 B+ Case, Aluminum Alloy Heavy Duty Passive Cooling Metal Case with Heatsink Pillar Compatible with Raspberry Pi 3B+/3B-Black (P252)

This is a great case at a great price. I had little stick-on heatsinks and no case before, and this lowered my temps by a fair bit compared to that. Fit my Pi very well and feels very sturdy. I did fell like the instructions weren't super clear and it took a little bit of figuring out on exactly which pads they wanted in which spots, but I got it figured out and it was pretty easy to install besides that.

I decided to start using my old RPi 3B to run LibreNMS to monitor my NAS. Since the Pi is just sitting on my desk, I also wanted something that looked a little more premium than the old plastic case it was in. The Geekworm case adds a nice amount of heft and has a very nice finish for $12. Assembly is very easy. Just apply the thermal pads to the Pi, slide it into place, and tighten the four screws. I had it together in under five minutes. The cooling performance is also very good. As I said, the Pi is running LibreNMS, so I was able to graph the temperatures before and after, and as you can see it shaved off about 10C for me compared to a small heatsink stuck directly on the CPU with no fan. Granted, the temperatures I had before were fine and this is just overkill at this point, but if you use the Pi for something more CPU intensive like game emulation, you could see a benefit from it.

Excellent construction with heavy duty design. This is a hefty little chunk of metal. CPU temps hover below 40 degrees. I bought two of these units and they're both working out great. Note there are different thermal pads depending on if you're using this with a raspberry pi 3 B or 3 B+. Extra thermal pads are included so you can reapply. Assembly is easy. Make sure everything is cleaned with alcohol before putting it all together.

Passive cooling is excelling for my always on devices. These are solid, cool well, and look great. It's a little tricky selecting the correct cooling "pad" to bridge the case to the ICs on the Pi, but not too bad.

Literally a great case! Heavy duty, and definitely uses a good alloy compound as heat dissipates quickly. Solid and snug fit against the pi, and ive been able to dramatically overclock the device since using this shell. Id give it 5/5 but the thermal pads are a little mediocre compared to the rest of the product. But still great that it comes with them, as they are necessary for heat transfer.

It is a surprisingly solid case I am impressed by the quality

Looks nice

Well designed and built. Very close tolerances - we machined. Nice powder coating. Comes with the heat sink pads, fasteners and an allen wrench to get it all together. Would buy again if needed, would also recommend. Very good product.
