Armor Case for Raspberry Pi 4 - Metal Case with Dual Fan Aluminium Alloy, Pi 4 Heatsink

I use this case in my CosmoStreamer build to livestream FPV drone flights at drift events, and it’s been outstanding. The metal construction feels strong and protective, while the dual fans and aluminum heatsinks provide excellent cooling. Even on very hot days, my system continues to run smoothly without overheating.Installation was simple, everything fit perfectly, and the airflow design really does the job. It gives me peace of mind knowing that my Raspberry Pi 4 is safe and stable during long streaming sessions.If you’re running a Pi 4 in a demanding setup like streaming or video processing, this case is a must-have. It keeps the board cool, protected, and performing at its best.

I have a Pi3 which runs plane spotting software in my garden shed in South Texas, so you can believe that the ambient temperature is pretty high. I would not have been able to run it 24x7 for the last year if it were not for the exceptional case/heatsink that I bought from iUniker here on Amazon. So when I finally got a Pi4 for Christmas and discovered that even indoors and idle, in the official Pi Foundation case, it was running at 76C (168F) and the wifi was consistently failing, I realised it was time to get another of these heatsinks. I got the fan version (now branded as MazerPi though I believe it is the same company that was iUniker), and after a couple of days of 24x7 running, it is staying steady at 42C and I have working wifi again.The Pi Foundation ought to be ashamed of themselves for selling this Pi4 that won't even run reliably in the official case (and that was in my 71F air-conditioned house, not my garden shed where the temperature reaches 100+ at times). It's fortunate that there are third-party cases that correct their overheating problems. Make no mistake, this is a heatsink and a fan rather than a case. It won't keep the dust out - there are plenty of exposed openings - what it does and does well is circulate the hot air away and keep your Pi4 running reliably.Only one small warning in assembling the case: the supplied thermal tape is easily broken and not very sticky, so separate it from its backing carefully (on both sides) and apply carefully. Other than that minor caveat, this is a nicely engineered all-metal case/heatsink and definitely worth the investment to save your expensive Pi4 from an early heat death.

Other than the cheap fan that quickly gets noisy despite being so small, this is a great thermal manager and convenient electrical barrier. It's simple and fast to put on, and never have to think about again. Upside about the fan is that you can simply disconnect it or replace it with a better one. With all the thermal mass, the fan hasn't really been important anyway.

I've been collecting and tinkering with raspberry pi's since they were first introduced. I've owned every single iteration and have purchased or made dozens of cases for each. This is, hands down, the best case I've ever had the pleasure of using on an rpi. The fans are almost silent, the case cools the entire system, and while looks aren't the most important thing for my use cases, this case is incredibly sexy. I'd honestly pay twice the price for a case this nice. Heck I HAVE paid twice this price for cases in the past that pale in comparison. Kudos to the manufacturer. Well worth the investment!

So 1. as a protective case, this really is amazing. Just keep in mind that the SD Card is not accessible once you put the case on.That said, it comes with 2 sets of thermal tapes, which actually work great as I had no issues putting the first set on. That being said, the only thing about this case I would call a "complaint" is it's inability to mount it to anything. You'll need to by longer screws for the bottom if you plan to also mount this to a bigger case or bracket to put somewhere else based on your use case.That being said with the case on, putting this under load in a Pi cluster with 4 Pi Zero W's and a full Apache Web Server LAMN (Linux Apache, MongoDB and Node.JS) stack and connected to 5TB of data and having it commit almost all it has to the job of indexing, sorting, etc. the MongoDB DB with 5TB of documents, the maximum temperature it reached was 37 degrees C. Normal operating temperature stand alone without load is almost 24 degrees. cAverage temp in general use is 28 degrees using it as a general desktop. Given the fact room temperature during these tests were 20.1 degrees C (70 degrees F)The heat dissipation was phenomenal, and this case was cold to the touch for me.

Perfect fit.Working like a champ after a year.Good purchase

Case arrived on time and was easy to assemble. The pi stays cool but the fans started making a loud grinding noise two days after the return window. I didn't see where I could contact the seller for a resolution. Just be aware that you may or may not have the same issue I have experienced. It's a nice case but the fans seem cheap.

Too soon to tell if the fans hold up, but the case is flawless: solid aluminum, fits perfect, with good fitment between the heatsink & pads, and you can't beat the price. Only complaint: there's no provision for mounting the thing! You can't replace the screws with spacers, since the fins prevent turning the typical 2.5mm standoff. I designed a simple mount, it's on thingiverse (search for Pi-4 armor case mount).

the fans look obviously cheep but they make little to no noise, you can barely hear.the H pins can be accessed but not when you need to fit a driver HAT for example.

Excellent

Excellent, as advertised

Nice product

Very good quality. Exactly what I needed to repair the fans on my Pi
