Geekwormfor Raspberry Pi 4 Armor Case, Pi 4 Computer Model B Armor Aluminum Alloy Passive Cooling Case Compatible with Raspberry Pi 4 Model B Only (Grey)

Not really a case so much as a big aluminum heat sink. It gives the Pi a nice bit of additional weight which makes it easier to handle and keeps it stable. Access to GPIO is good enough for testing. The SD card does poke out a bit from the structure, so don't drop it on its end.

It is a good case for Raspberry Pi 4. It dissipates heat very well even I play video and running bench mark together. It also exposed the GPIO pins for interface. Unless you use the pI for media center or NAS then you can use the enclosed case otherwise this one is a must..

Case fins get quite warm to touch so it seems heat sink is working. Case is attractive and small. I am unsure about actual contact with rpi but no problems otherwise.

This heat sink is large enough for overclocking with out a fan. We stuck a 5vusb fan on top for when we really push the Pi4. Only issue is that it doesnt give much versatility when having to mount it to make the Pi4 more desktop like.

This case acts as an effective heat-sink for the Raspberry Pi 4. There is no fan so no need to connect GPIO and of course it is silent. The quality of the aluminum case is very good, and assembly is easy.My only complaint would be that the MicroSD card protrudes slightly. It could be subject to damage if the case was dropped.

This is very easy to install, the fit is very precise, and it cools better than a small fan.WiFi signal is strong - all signal bars are lit.I have two Pi 4 - one in a plastic case with a fan (from Canakit) and this one.The Armor case looks very sharp and it gives the Pi a very solid feel with some added heft that helps prevent the Pi from moving around so easily.Two GPIO extenders are provided, that is a nice touch.EDIT:Here is some info on thermal data points after using this case for a few days.Using the 'stress-ng' package I ran the command:stress-ng --cpu 0 --cpu-method fftwhich runs a stress test using 100% of all 4 cores.I ran this on both of the PI 4 models I have which run the same software and firmware upgrades (same SD card copied for each). One uses the GeekWorm Armor case, the other is the Canakit clear case with fan.Ambient temperature was 20C during these tests.On the Armor Pi, the CPU temps rose very slowly until levelling off at 74C with occasional dips and peaks of 73 and 75.It took about 1 hour for the case to reach thermal equilibrium. The case was quite warm to the touch, but did not hurt. Stopping the run causes temps to fall slowly.On the Canakit Pi with small fan, the temp rose quickly to 68C then slowly stabilized to 72C after about 30 minutes. There were occasional dips and peaks of 71 and 73.The plastic case was warm to the touch, but not hot.Stopping the test caused temps to fall quickly.Both of these cooling solutions are adequate for my needs. I think I find the Geekworm case more appealing visually, very sturdy, and the GPIO is easy to access.Additional info:I placed a spare 12v 120mm computer fan slanted on to the case to provide temporary air flow as a test. (See image). This is a quiet fan with low air flow, but after several hours running the stress-ng test as above, the temperature stayed at 40C. So even a small amount of convection improved the cooling ability.

No noisy fan that can break. Permits Wi-Fi and Bluetooth RF signals. Access to connectors. Stays in place like a paperweight.

Once the Raspberry Pi 4 came out, I knew it'd be a good device for some of my projects. When it comes to finding a case, I've always purchased the clear and black zebra cases from C4Labs. However, the Raspberry Pi 4 has so much computing power, in such a small package, that it requires significantly more cooling than previous versions; which is why C4Labs doesn't currently offer a zebra case, for the Pi 4, that doesn't also have a cooling fan.I opted to try this case because it avoids the requirement of a fan by using the entire case as a heatsink. Before buying it, I read some of the reviews which claim that the manufacturer fails to provide adequate heat-conductive strips for contacting the processors to the case. After using this case, I find that to be untrue. Now that my Raspberry Pi 4 is up and running, I can touch the case and feel that it gets quite warm, which is evidence that the strips are doing a fair job of conducting heat.Overall, I'm very pleased with this case, and am glad that this fanless option is available. Because it has no fan, I have access to all GPIO pins, the device is quiet, and I don't have to worry about a fan breaking. As is the case with the rest of my Raspberry Pis, I can build it, set it, and forget it. If heat ever does become a factor, there's nothing to stop me from placing the device in front of a fan. The case is a heatsink, after all.I recommend this case to anyone who wants to use their Raspberry Pi 4 without having to deal with a fan. My Pi 4 runs 24/7, and so far, I haven't had any problems.

Great product. Reduced the temperature of my Pi CPU significantly. Stylish too.

This gap has been discussed before in the reviews, but there is simply no excuse for it.Board thickness plus the CPU and its metal lid (the heat spreader) are consistently an exact thickness and therefore this heatsink/ case manufacturer should be able to make their heatsink just thick enough to apply several pounds-per-square inch of pressure to the CPU (plus a bit of thermal grease).This would ensure excellent thermal transfer properties instead of nonsensical wide gap and use of a rubber strip to fill the gap.Note to mfg: it's common for CPU to have significant downward force applied from the heatsink. The Pi is no different and can accept this force as well.

Rs50 to Rs100 heatsink can do the same performance as this unit can do. It may be problem with Raspberry Pi design it produces lots of heat. Devices like firestick or appletv or google chromecast can provide you better performance if you can crack the device and install your own version.

It's a pretty amazing heatsink for the price. It's well made and there are no sharp edges or anything like that.The provided thermal pads cover the CPU, RAM and USB controller. No excessive mechanical stress is placed on these chips as a result. The WIFI and Bluetooth antennas are covered by the heatsink, but reception is not affected in my case. I have no before and after signal strength measurements and so cannot tell you what the effects are in detail other than that it still works fine.I do not overclock the Pi and under load the case reaches a temperature where it becomes a nice handwarmer, but nothing more. As a passive cooler this is a very nice solution.

The one thing I neglected, that isn't readily mentioned in the description but ought to be inferrable from construction, is that this case will interfere with wireless communication: WiFi and Bluetooth. Vendors ought to make this warning a little more prominent. Otherwise, it's a very inexpensive case that doubles as passive cooling, which is exactly what I wanted. Good purchase! Recommendable.
