Raspberry Pi 4 Case, Miuzei Aluminiun Raspberry Pi Case Passive Cooling with Heatsink Cooler for Pi 4 Model B 8GB/4GB/2GB

Seems nice and durable. I like that the case itself is the heat sink. This Pi is used as a print server and it runs a lot without overheating.

I had never been able to find a metal case for a raspberry pi that had everything I needed until now. This is my 4th case, but I'm sure it'll be the last. First, the case easily accommodates a GPIO ribbon cable, which very few do. This is very important for me, because I want all the pins accessible but to still have the pi securely boxed up. The case is heavy (in a good way!) and is well machined--the two pieces fit together very snuggly. This is not cheap sheet metal. It comes with some adhesive thermal pads that connect the chips to the top of the case for heat dissipation. This should be considered a semi-permanent install, since the pads have to come off either the chip or the case for it to be opened. I don't think I'll ever need to open it again though, since I have a ribbon cable coming out. The SD card slot is accessible as well. A second set of thermal pads is included just in case.The passive cooling works quite well. See the 3rd image in this review. The blue curve shows the cpu temp and the orange is the clock speed for each of the 4 cores. The cpu is set to idle for 10 minutes, followed by a 1 hour stress test at 100% cpu usage, followed by another 10 minutes of idling. Ambient temperature if 68 F/ 20 C. The cpu idles at under 40 C, and at full load levels off in the upper 50s and never hits 60. You can see no thermal throttling of the cpu took place, as the cores stay at 1500 MHz during the entire stress test. Keep in mind that a bare raspberry pi 4 tends to idle in the mid 50s. This case does a great job of cooling and is completely silent! I think it's safe to say you will not experience any thermal throttling in a normal room temperature environment, even if you run your pi at 100% 24/7.

There is not fan in this case, the whole case is a huge passive heatsink, sometimes gets a little warmish/hot but that is perfectly normal and expected in a fanless case, your processor dont going to melt, it do the job and it is a solid armor for your internal card.Access to the micro SD is easy.Size is very good the box is almost the size of a pack of cigarettes.Strong construction what is expected from a solid piece or aluminum.Esthetic wise is a good looking and finished box with no dents, sharp edges and finished in a flat black color.I havent rated a product 5/5 for a while but this one serve it.

Using the case as a heat sink is very reliable option. The quality of this case is very good too. The two shells close together accurately without misalignment or sharp edges. The tiny rubber feet which come in the package work very well too. The pi board is easy to fit into the case and it fits tightly. I only wish the screws were phillips type as opposed to hex heads. Phillips is easier to deal with.I measured its cooling performance and this case cools the cpu a step better than the Flirc/kodi case which I had before. I recommend using the copper plate + thermal paste as opposed to the rubber conductive pad. The copper plate conducts heat considerably better and keeps the cpu 3-5'F degrees cooler than the stick-on pad.

This is a great little case and feels solid and sturdy. It has well placed cutouts so you can get a ribbon cable out of it for the GPIO, and you can get a little flex cable out the back for the display connector, but there is not a good way to get a flex cable out for the camera without doing a couple of folds on the flex cable.The product images show a camera flex cable exiting the case on the far side of the case, but there not an exit hole there and anyway if the cable did exit that way it would get squished between one of the ICs on the Pi4 and the corresponding pokey-down part of the case.The case comes with all the hardware you need to put it together, plus a hex key and thermal pads. Great value for $10. Just want to point out the discrepancy between product image and reality.

Miuzei Aluminum Case For Raspberry Pi 4Purpose:A case with passive cooling without fan for everyday applications such as general computing, NAS file server, VPN, automation device...etc.The product and Design:The whole package came with everything needed to put it together plus an extra set of thermal pads and 1 extra screw.The case is 2mm thick with GPIO and display slots. There are 4 pin rods that conduct heat from the processing chips to the aluminum case. The rods to the cpu and ram are bigger and wider which would transfer more heat off compared to some of the other similar cases. There is one rod to the small tiny chip by the USB-C PD port. I believe Miuzei studied thermal images of how and where the raspberry pi 4 generates heat the most, and also follows the newest update on the efficiency of the new firmware. There is an article on the Raspberry Pi Foundation regarding the update. The top of the case has the fin-like texture to act like a regular heat sink to hopefully dispense heat better.Once assembled the case feels very sturdy and firm, all ports including MSD card slots could be easily accessed without any trouble. While assembling I ran into a little bit of trouble when putting the screw into the case. One of the screw holes wasn’t very well polished andI had to force that single screw in. Probably just my luck.Test:Stock settings CPU 1.5GhzRaspberry Pi OS latest December 2020 versionRoom temp: 25c10 min idle temp: 38cCase: 34.3c10 min video stream temp: 55cCase: 46.4c1 hour video stream temp non stop: 56.58cCase: 48.6 (a bit hot to touch)The case performed well but couldn’t help but to notice the last test. Therefore added a battery powered fan on top without turning the last test off,Fan added Test:Stream non-stop from last test: 40c in minutesCase: 30c (very cool to touch)10min stream video 1080p@60fps: 38cCase: 28.8cOverAll:The Miuzei aluminum raspberry pi 4 passive cooling case served very well for its intended purpose from the simple test. However, it needs to be aware of the environment temperature and avoid touching the case if it has been running constantly(busy) for a long period of time. Remember the case itself is basically a big block of heat sink. Plan what you use it for and everything will be fine.
