Geekworm for Raspberry Pi 4 Armor Case, Pi 4 Computer Model B Armor Aluminum Alloy Passive Cooling Case Compatible with Raspberry Pi 4 Model B Only

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.

I found this to be an excellent passive cooling case for the Raspberry Pi-4.I wanted a case that worked with the Pirate Audio shield, this case does an excellent job of protecting the Pi while providing effective cooling without the need of a fan.The case is made out of black anodized aluminum. I had no issues with fit or finish. The lid of the case has precision machined heat pipes that contact various components on the Pi, die-cut double-sided thermal tape is provided to facilitate heat transfer between the Pi and the case. In addition, two IO pin connectors are provided, allowing you to extend the Pi’s IO ports if required. A single IO extension worked with the Pirate Audio shield, two provided a bit of extra space between the shield and the top plate of the case. As you would expect, the case has openings for all of the Pi’s portsInstallation is very simple, place the pre-cut heat-tape on the Pi’s components as outlined in the instructions, align the Pi on the base, set on the top plate and bolt together with the four screws. Everything required, including an Allen wrench, is provided. Installation is quick and easy.I found the case did a good job cooling the Pi, thermals stayed well within the optimal range, even under extended use.I’m very pleased with this case, it is compact, robust and thermally efficient, all at a reasonable cost.

This is the best when it comes to heat sinks, the entire case is one big aluminum heat sink and works great. The customer support was great too. I had 2 stripped taps and they sent me a new one asap. Works great.

Great, pretty rugged, nice heat dissipation on my 4B, and to this engineer, it just looks good.Also ordered one for a friend as the cheap small fans on both of our original plastic cases failed. This does not need a fan, so there is nothing to go wrong here.

I really like these raspberry pi cases, they seem to work well dissipating the heat while protecting me Pi. I have purchased two now. The only drawback to these is the mounting. They really need to provide mounting tabs on two corners with screw holes. As you can see from the photo my application was a vertical mount. There is no way to put a strap around the unit to mount because of all of the cable ports. I had to mount the case to an aluminum plate and then screw the aluminum plate to the wall. This meant I had to drill 8 holes in the aluminum plate, two holes to mount the plate to the wall, two holes to mount the case base to the aluminum plate and four holes in the plate to allow access to the mounting screws holding the base of the Pi case to the top of the case.

Three of four screw holes are stripped and won't hold a screw. Replacement works fine and runs CPU at under 40c when idle
