Review on 🔥 GeeekPi Raspberry Pi 4B Armor Case with Passive Cooling | Aluminum Case with Heatsink for Pi 4B/3B+/3B by Karl Swift

Use on Pi3B+. It keeps the system temperature a few degrees cooler (without a fan) than small fan heatsinks and has the advantage of not consuming power. Wi-Fi also seems to work well, even with the case on. The biggest problem is that you can't adapt to the GPIOs because the space around them is too small. It just looks like a design flaw. The included headers are a workaround for this, but you must use BOTH as one of them alone isn't big enough. And then your spade sticks out over the armor instead of being neatly tucked away and protected. I'll probably take it to a locksmith and unclog it, but they should have done it for us.
