Review on 🔧 GeeekPi Acrylic Case with Cooling Fan and 7PCS Heatsinks for Raspberry Pi 4 Model B & Raspberry Pi 3 Model B+, Brown by Andrea Larson

This case is great for the Pi 4B. Without a small fan, there is enough room for air movement. The camera connector on the 4B board and the slot in the case match exactly, so you need a ribbon cable to connect the Pi to the camera. never mind. The included fan does not indicate the direction of airflow, but if you want to mount the fan so it blows down toward the board, mount the fan so the labeled side of the fan is closest to the Pi processor chip.
