* 1. After '''Why is it compatible with the Raspberry Pi pi 4 was released, we found that the heat generation of Pi 4 also increased greatly expansion boards?'''# The P165(P165-A) Embedded Armor Aluminum Alloy Heatsink Radiator is 7mm high (designed with its performance. We have encountered many times that Pi 4 crashed due to excessive heat generation. This problem can be satisfactorily solved by use the Raspberry Pi 4 armor case negative tolerance) and is equipped with other Pi 4 external expansion boardM2.5* 2. At 5+5 copper spacers; so the same timetotal height is 12mm, we found that various types which can support most of Raspberry Pi 4 expansion boards such as DAC+(not support PoE expansion board); if you use expansion board with other height, UPS HAT, or various LCDs on you only need to replace the copper spacers with the market also encountered excessive heat generation when used on Pi 4right height. So we try to solve this problem(If you need a special height copper spacers, please contact us.)* 3. We refer # The raspberry pi hat positioning hole has internal thread for easy fixing from above or below; Compared to the design of Raspberry Pi 4 armor case and simplified the design raspberry pi PCB, so there is the birth of this Embedded Armor Aluminum Alloy Heatsink Radiatorentire heat sink shrinks inward by 0.5 mm.

'''Why is it compatible with the use of expansion boardsdesign this new P165-B 11mm heatsink?'''

The Embedded Armor Aluminum Alloy Heatsink Radiator is 7mm high (designed with negative tolerance) and is equipped with M2.5*5+5 # We found that the copper spacers; so the total height is 12mm, which can support required for most of Raspberry Pi 4 expansion boards; if you use expansion board is 11mm, so we designed this 11mm embedded heatsink(P165-B). Compared with other heightthe old model(P165-A), you only need to replace the copper spacers with heat dissipation area is increased and the heat dissipation effect will be better; # at the right height. (If you need a special height copper spacerssame time, please contact us.)this new version support POE extension;

The raspberry pi hat positioning hole has internal thread for easy fixing '''What if the Raspberry Pi 4 expansion board comes into contact with the P165-B 11mm heatsink?''' * Please use the 2*20 female header to add the height of expanion board. ==Update History==# 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 above or below;P165.Compared # On July 2020, update the cooling fan of P165 embedded radiator from 2506 to 2507.# On April 10th, 2020, the raspberry pi PCBP165 embedded heatsink has been updated to attach thermal tape at both CPU and RAM at April 2020, the entire first version just need to attach proper thermal tape at RAM.# On September 29, 2019, Geekworm release this Raspberry Pi 4 Model B embedded aluminum heatsink to help slove Pi 4 excessive heat sink shrinks inward by 0generation problem.5 mmThis heatsink, which called P165, can also be used with a cooling fan above.

* Only supports Raspberry Pi 4 Model B; * Supports to cooling down the Raspberry Pi 4 board when using the Pi 4 expansion board;(Do not support Please choose P165-B if you need to use it with PoE expansion boardsboard) ;* Equipped with a variety of screws and copper spacers;(The screw packs of P165-A and P165-B are different); * Raspberry Pi HAT positioning hole is M2.5 internal thread; (this design is convenient to fix) ;* Supports the fan installation of 25mm fans; Cooling fan can be added when the heat dissipation of a single aluminum heat sink is not enough, so that all heat dissipation problems can be solved. * The fan equipped with the heatsink is the same fan as the official POE expansion board;
