Seeed Studio Armor Lite Heat Sink

Seeed Studio Armor Lite Heat Sink is a thin and lightweight heat sink, equipped with a 3510 ultra-quiet cooling fan. It's suitable for the Raspberry Pi 4, and provides better heat dissipation through passive cooling. The heat sink provides faster cooling through active cooling using a PWM fan. The speed of the fan is controlled using a Python script provided. It's compatible with the Raspberry Pi OS. Other systems need to manually write Python or C code to drive the fan speed through PWM. It is very easy to install and provides a good contact surface between the onboard components and the heat sink with the use of the included thermal pads.
