## Description

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

## 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

### ⭐⭐⭐⭐⭐ Got it to fit in a RasPad 3
*by C***F on May 15, 2022*

Works great. I wanted a slim heat sink option to fit inside my RasPad 3 enclosure. I got it to fit by taking off the included fan on the heat sink and replacing it with the fan from my RasPad enclosure. The RasPad fan is large so you wont get all 4 screws in. I just tightened one screw in making the fan face the heat sink and it held fine. The Pi gets much better cooling compared to previous setup.One tricky part with the RasPad is getting the small accelerometer shim back on the GPIO pins for the auto rotate screen feature. I just soldered the shim to some 2x3 female pin headers to make it hold solid. If you use header pins the case fan won’t fit in its normal spot. If you move it into the heat sink like I did you won’t have a problem. If you get the shim on without header pins you can bend the GPIO pins to help retain it in place, but it was hard. I wanted a more solid connection.

### ⭐⭐⭐⭐⭐ Essential Cooling Upgrade for Raspberry Pi 4 Model B
*by O***O on July 2, 2024*

The installation was straightforward and hassle-free. The heatsink kit came with thermal adhesive pads, making it easy to securely attach the heatsinks to the main processor and other heat-sensitive components on the Raspberry Pi board. No additional tools or technical expertise were required, which is a big plus for users of all experience levels.

### ⭐⭐⭐⭐ Nice and slim
*by J***A on April 4, 2025*

Affordable cooling protector that was easy to use.
