Key Features
- Compatibility Compatible with Raspberry Pi 4 Model B 1GB/2GB/4GB/8GB, embedded heatsink with 11mm thickness; Model P165-B
- 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 grease The theoretical value of the gap between the heatsink protrusions and the CPU, RAM and other chips of Pi 4 is 0mm; Strongly recommend to use CPU grease to get better heat dissipation
- Only equipped with 4pcs M2.5x5+5 mm 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
