Review on 🖥️ Vilros Raspberry Pi 4 Heavy Duty Aluminum Alloy Case with Built-in Fan - Preinstalled and Ready for Optimal Cooling (Black) by Adam Browning

This is my second fan-cooled Raspberry Pi 4 and Vilros aluminum case. I use the RPi 4 as a high-resolution music streamer with Volumio and love the ease of building the RPi 4 and connecting the fans in this case. I use 3.3V DC (pin 1 on GPIO) and GND (pin 9 on GPIO). At the same time, the fan runs quietly. It's so quiet that the only way to know if the fan is running is to look down at it. This is perfect for keeping the RPi 4 cool while listening to music on my high-end audio system. As with my first Vilros RPi 4 kit, everything fits together beautifully. The case comes with heatsinks for the CPU and RAM chip. The other two heat-dissipating chips are cooled by built-in racks that come into contact with them when the case is properly assembled - a very clever design. The RPi 4 is great for audio as the USB ports are separated from the Ethernet port bus in this version. I can run a high-resolution 32-bit/384kHz DSD256 USB DAC from a USB 2.0 port by connecting a 2TB LaCie Rugged Mini USB Hard Drive to one of the USB 3.0 ports. With this setting, I was able to hear high-quality sound with no noise.
