![]() If you want to print the case, you can download (free account required!) 3D files from these pages: Maybe a variant with more headroom would be useful in some situations (the first heat sink on my Raspberry Pi was a bit taller and it was not possible to close the lid). The development mode is clever and no screw is required to attach the fan. If you have access to a 3D printer (at home, in a fab lab, online service) and if you need a case for your RPi 4, here is a nice and ready-to-be-printed case. The Pi-Fan plugged on the 3.3V of the GPIO:Īnd the noise? It’s much better now, the fan is barely audible and keeps the CPU more or less at the same temperature. Remark: the fan is fixed to push air onto the CPU, it provides a better cooling. ![]() Let’s try to plug the Pi-Fan on the 3.3V. It’s a CPU and GPU test at the same time: the video decoding is done on the CPU and is multi-threaded, and the rendering is done via OpenGL.Īnd some noise. YAFFplayer is handy because it can be used as a stress test on the Raspberry Pi 4. To stress test the Raspberry Pi 4, I launched YAFFplayer with a full HD video. Test 1: No fan, passive cooling (heat sink only), opened case I put my Raspberry Pi 4 into the case, connected the Pi-Fan to the 5V + ground pins of the GPIO. Now let’s see the case and the Pi-Fan in action. – development mode: in that mode, the lid is spun by 180 degrees and gaps are available for wires ( GPIO). – desktop mode: the case is completely closed. The Pi-Fan can be attached to the lid without screws. The printed case is made up of two parts: a lid and a base. ![]() It’s a small 30x30x7mm fan that can operate at 3.3V or 5V. The Pi-Fan is a common fan used in several cooling systems for Raspberry Pi. This case is designed to work with Pi-Fan-like fans. I received few days ago a 3D printed case for the Raspberry Pi 4 from 219 Design.
