Armor Lite Heat Sink with PWM Fan for Raspberry Pi 4B

Features Easy to install Provides better heat dissipation through passive cooling using a heat sink Provides faster cooling through active cooling using an adjustable speed control ultra-quiet fan Provides a good contact surface between the onboard components and the heat sink with thermal pads Description This is a thin and lightweight heat sink, equipped with a 3510 ultra-quiet cooling fan, that is suitable to use with the Raspberry Pi 4. It provides better heat dissipation through passive cooling while protecting the Raspberry Pi. Also, it provides faster cooling through active cooling using a PWM fan. The speed of the fan can be easily controlled using a Python script provided, which is perfectly compatible with 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. Note Automatic speed control function is only supported by Raspberry Pi OS How to Assemble Note Please beware of the direction of the screws and nuts Part List 1 x Armor lite heatsink with PWM fan for Raspberry Pi 4B 1 x Screwdriver 2 x M2.5x6mm Screws 4 x Thermal Pads 1 x Instructions
