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

I really like the case. Its very nicely made. I really wish it would keep my overclocked Pi 4 cool, but it doesnt, hence the 4 stars. If you dont overclock or stress your Pi 4 like I do, this is the nicest looking passive cooling Pi 4 case.

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.

Worked as described. Wifi reception doesnt seem to be affected. Resting the RPi on the side actually improves the wifi through put.

Beau et fonctionne très bien température inférieure à 46°C avec une température dans la pièce autour de 21°C avec Jeedom sur le RPI4 et surtout sans bruit. Facile à monter en suivant les quelques étapes du document fourni je recommande.

Unbelievable how it reduces the temperature even under stress! Better than case with fan Buy it, don’t think twice.

Really happy with this product. Before the Pi CPU was constantly around 60-65° Celsius. Now, been using this new case for a few days, and the passive cooling keeps the CPU temp between 30-35°. Pros: the design is cool, well built, saves energy, noiseless, likely increases the Pi lifespan. Con: a bit pricey (£29.99), but Id rather pay for quality. If you can afford it, I definitely recommend this product.

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.

Fantastic case, well built and perfect for keeping the PI cool

Somewhat difficult to get the heat sinks mounted lined up. Solid aluminum - very sturdy Corners are sharp

Case un po’ caro, ma le temperature mi sono scese di 20 gradi (sotto Plex file in 4k), da 63/64 a 42/43 gradi. Molto bello esteticamente.
