Akasa Pi-4 Pro, Pure Aluminum Raspberry Pi 4 Armor Case, Zero-Noise Passive Cooling Rpi 4 Case, Raspberry Pi 4 Heatsink for Raspberry Pi 4 Model B, Thermal Kit Included, A-RA08-M2B

This case is great! It does everything its supposed to do: fitment is good, looks unique, protects the board well and seems to have great thermals as advertised. On/off button works great with the addition of a single line of code in the config. Recommend for a silent but cool running setup!

Bought 2 of these and had the same problem that the clearance between the board and casing resulted in the Micro HDMI unable to electrically contact the socket pins, hence no display output. I took out the Raspberry Pi board and connected the micro HDMI directly and that works. This shows this casing design is not good.

Simply put, I wanted a case for my Raspberry Pi 4 that would let me to max its overclock and passively keep it cooled and this case does just that. I wanted to be able to drop the Pi in a place and forget about it, even if it was a couple of years. i didnt want a case where I had to also use a fan and have that fan possibile go bad during that time and compromise my Raspberry Pi. The Akasa Gem Pro case is the only case I have come accross that allows me to do this. I keep my Pi overclocked at 2140 MHz and the tempeture has never gone to 60c, and usualy is between 48c to 55c. I am so happy with this case, that every Raspberry Pi I build from here out will use the The Akasa Gem Pro case.

This case is well machined and provides great thermals through its passive cooling. The IO lines up perfectly and the steps in the instructions were simple enough to follow. Its all fits together nice and snug. My only complaints are that the case doesnt come with any non-slip rubber feet, so I had to stick my own on, and there isnt any included power button. Overall, love the design, feels very smooth and premium, keeps the Pi cool!

TLDR: The Good: This case is excellent for cooling the Raspberry Pi 4. Can overclock and the Gem Pro case keeps the Pi4 at 47C. The Bad: No feet. The connectors are really recessed; changes to cables may be necessary. Note: I highly recommend using a high quality thermal paste for the best results. Stress Test: I installed Raspberry Pi OS, then Stressberry. I ran it on stock speeds, then I overclocked it to 2000MHz for the CPU, and 600MHz for the GPU. (Voltage was increased as well.) For the first tests, I used the thermal pads and white thermal paste. (I think I put too much paste on the first time.) Then I replaced the white paste with Noctua NT-H1 thermal paste. Finally, I replaced the thermal pads with thermal paste. The room was at 23.3 C (74 F). All three tests took 10 minutes each, and both CPU and GPU were overclocked. Test 1 : Max 53C (too much white thermal paste, bad heat dissipation) Test 2 : Max 50C (Noctua on one side. CPU thermal pads slightly damage. Much better, but can get cooler) Test 3 : Max 47C (Replaced thermal pads with Noctua.) With this case, I feel confident in overclocking without damaging the Pi4. Because its silent, Ill be replacing my cases with fans with this one. The Bad 1. There are no feet provided to prevent the case from scratching surfaces. 2. Cables may need to be modified to fully connect. Between the thickness of the aluminum, and how recessed the connectors are, cables may need to be trimmed. While every other cable worked, the HDMI adapter cable wouldnt connect. Trimming a sliver of plastic from the connector allowed the cable to connect. Not taking away any stars as this could be an issue with the cables I bought.

This is one of the best passive cases on the market. Used with a heavily overclocked RPi4B it has managed to keep the SBC stable at very reasonable temps.

I dont need to open the hole for the video mini hdmi work fine for me.

Cooling: I used Arctic Silver 5 between the heat transfer blocks and their corresponding recesses in the case. I also used it for the CPU to transfer block interface. I ran stress-ng and cpuburn-a53 and didnt not get a CPU temp reading above 40C. For some reason, I expected it to be higher. Ill have to recheck my methods. HDMI cable: The micro HDMI adapter was not long enough to electrically engage when plugged in, so no monitor. I suppose I could have shaved the plastic from the end of the micro HDMI connector until it worked with the stock opening - a couple of mm would have done it. Nope. I used a dremel to enlarge the opening to fit my cable. The thing has five-star cooling and a one star-fit. But it cools so well I deduct only one star. If I need another Pi case, Im buying one of these.

Trop cher. Qualité n’est pas top. Prix ne mérite pas la qualité

Je connaissais déjà les boitiers Akasa qui équipaient mes Rpi 3. Cest donc tout naturellement que jai investi dans ce boitier lorsque jai migré mon Jeedom vers un Rpi 4. Niveau finition, pas grand chose à dire. Cest propre et net. On ne voit pas forcément bien sur la photo, mais le boitier est couleur aluminium (et non blanc comme on pourrait le penser) Le montage du Rpi se fait très facilement, à lenvers. Cest à dire que les vis se mettent sur la face du dessous du Rpi. Cest bien plus facile que beaucoup dautres boitiers, étant donné que cette face est toute plate, et pas encombrée par les divers connecteurs. Niveau performance, cest juste top. Je passe de 60-62°C, avec le Rpi libre cest à dire sans aucun boitier, en faisant tourner Jeedom, à 41-43°C avec ce boitier. Tout ça dans un parfait silence. Bref, je recommande +++
