Geekworm 7mm Thickness Embedded Heatsink with Fan (P165-A) for Raspberry Pi 4, Armor Aluminum Radiator with 5V Cooling Fan Compatible with Raspberry Pi 4 Model B Computer - TB-2019-38

• Compatibility: P165-A is only designed for Raspberry Pi 4 Model B 1GB/2GB/4GB/8GB, ultra-thin embedded heatsink with ONLY 7mm thickness. Model: P165-A User manual: Google Geekworm Wiki and search P165 to visit the manual Supports to cooling down the Raspberry Pi 4 board when using the Pi 4 expansion board(do not support PoE board). Compatible with Raspberry Pi 4 expansion board, such as X825/X862/X857 to slove the Raspberry Pi 4 overheat problem Update: We only keep the M2.5x5+5 mm, M2.5x13+6 mm spacers in the P165-A packing list, due to the Raspberry Pi expansion board usually with 12mm or 20mm height, the spacers combination is enough in application Raspberry Pi HAT positioning hole is M2.5 internal thread. (this design is convenient to fix), use good quality mute 5v cooling fan, don't worry about the noise of fan Supports the installation of 25mm fan. Cooling fan can be added when the heat dissipation of a single aluminum heat sink is not enough, so that all Pi 4 heat dissipation problems can be solved
