Miuzei Case for Raspberry Pi 4 Model B 4GB 8GB Aluminum Passive Cooling

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.

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.

I used this for a silent media server and pihole mounted on velcro on the back of the TV stand. It never goes over 50C while multiple TV streams in the house are running from it. Multiple thermal pads included, the top half of the case is a big aluminum heatsink- very effective. They look great too. I definitely will be buying a few more of these. Great value for the money.

This case is exactly what I wanted, functionally and visually. It is almost perfect, I am very satisfied for $11. My Rasp Pi runs cooler in this case than my previous stamped steel case. I did have 2 issues thou. 1) One of the corners had a small scratch that showed some bare aluminum. Nothing a black permanent marker didn't fix. 2) One of the holes for the screws was not drilled completely straight. I had to start all the other screws and leave them loose while I carefully screwed in this one. Once it was tightened I easily torqued the other screws. Overall I'd definitely buy this again.

This is a great product and I've purchased over 40 of them. There is absolutely a design flaw on one of the screws - it's always the same screw/same hole. I recommend the company review this - grab a handful from your inventory and you'll find it's the same screw/same location every time doesn't line up - you need to push the screw at an extreme angle and push hard in order for the thread to push through. Please fix this and this will be a perfect product!

Before installing this case, my Raspberry Pi was running around 63.7°C despite being supported by a high-end active cooling system (a desk fan pointed directly at it). After installing the case with the included thermal compound, temperatures dropped into the 40–46°C range, completely passively. Overnight it even hit 40.4°C. That's a temperature drop of up to 23°C (~42°F) with no fan, no noise, and no moving parts. For around $10, that's ridiculous. The case feels solid, looks great, and apparently comes with the following stats: Legendary Passive Armor +23°C Thermal Resistance +100% Fan Noise Immunity +1 Moving-Part Elimination Passive: Ambient Communion — Temperature follows the surrounding room instead of slowly cooking itself. Also looks vaguely like AUTO is about to overthrow the ship. 10/10 aesthetic. 10/10. Would equip again.

Fits raspberry pi 4b. Note that the holes in the case do not line up in with the two holes of the PCB. The pi PCB lines up with the two nubs on one side. I used the copper heatsink spacer and heat sink compound. Transfers heat very well. Case warm to the touch. 39C at idle. 42-44C under 10% load. Would buy again.

Surprising good build for the price. It's sturdy and effective. I like having the option between thermal pad or copper+grease for the CPU cooling column. The feet are included, look for them in both bags. I didn't immediately see them.

Case assembled with ease with sturdy look and feel. Perfectly aligned ports except for the four holes to secure Raspberry Pi board to the bottom half casing. Only two are aligned the other two is not. Casing feels warm that means it is doing what is supposed to do, to passively cool you RPi without fan.

almost perfect, my only complaint is that the cover has one hole that doesnt align with the case threaded hole so one screw was impossible to install.

The case has good fit and finish, came with extra thermal pads and an extra screw, and offered the option of using a copper plate and thermal compound instead of a thermal pad for the CPU. The case gets satisfyingly warm all around as it dissipates the heat from the CPU. I'd buy another if I got another pi 4, and I hope they'll update the design for the pi 5.

Basic but solidly built case, with a passive-cooling solution that works very well. No need to be concerned about fan failure, or the noise of a cooling fan. Functioning as a pi-hole and music server my pi is happily sitting in the low 40s celsius with this case with ambient at 24C (this is using the included copper shim, not tried without). Would certainly buy again.
