Geekworm Raspberry Pi 4 11mm Embedded Heatsink (P165-B), Raspberry Pi 4 Heatsink/Radiator Compatible with Raspberry Pi 4 Model B Computer and Pi 4 Expansion Board Support POE Extension

New version Geekworm embedded armor aluminum alloy Heatsink (P165-B) is only designed for Raspberry Pi 4 Model B 1GB/2GB/4GB/8GB Version, embedded heatsink with 11mm thickness. User manual, refer to Geekworm WiKi search P165.
Supports to cooling down the Raspberry Pi 4 board with Pi 4 expansion board(reserve the PoE port of Pi 4); Compatible with Raspberry Pi 4 expansion board to slove the raspberry pi 4 overheat problem, BUT you will need to prepare the proper standoffs or screws to use the P165-B with other expansion board.
Recommend to use CPU thermal conductive greaseThe theoretical value of the gap between the heatsink protrusions and the CPU, RAM and other chips of Pi 4 is 0mm; It is strongly recommend to use CPU grease to get better heat dissipation;
Only equipped with 4pcs M2.5X5+5mm spacers for the P165-B embedded heatsink, you will need to prepare extra standoffs or screws for Raspberry Pi 4 with other expansion boards.
Supports the installation of 30mm fan(3010 or 3007 fan); Cooling fan can be added when the heat dissipation of a single aluminum heatsink is not enough, so that all Raspberry Pi 4 heat dissipation problems can be solved.
