# The P165(P165-A) Embedded Armor Aluminum Alloy Heatsink Radiator is 7mm high (designed with negative tolerance) and is equipped with M2.5*5+5 copper spacers; so the total height is 12mm, which can support most of Raspberry Pi 4 expansion boards(not support PoE expansion board); if you use expansion board with other height, you only need to replace the copper spacers with the right height. (If you need a special height copper spacers, please contact us.)

# The raspberry pi hat positioning hole has internal thread for easy fixing from above or below; Compared to the raspberry pi PCB, the entire heat sink shrinks inward by 0.5 mm.

==Update History==
==Update History==
# Jan 2026 Upgrade: Height increased from 7mm to 8mm for better heat dissipation. Compatibility remains virtually unaffected, but accessories have changed – please refer to [https://wiki.geekworm.com/File:P165-A_8mm_version_packing_list.jpg P165-A 8mm version]. Both versions are currently shipping.
# We only keep the M2.5*5+4mm,  M2.5*5+5mm,  M2.5*13+6mm spacers in the P165-A packing list(in August 2021), due to the Raspberry Pi expansion board usually with 12mm or 20mm height, the three spacers combination are enough in application.

# On November 11th, 2020, based on customer feedback, a slightly thicker version was released, which is 11mm thickness. It supports 3010 cooling fan, will have a better heat dissipation function and compatible with PoE expansion board. This new embedded heatsink is named P165-B, while the old radiator will be renamed P165-A from P165.
