Description of Geekworm Raspberry Compatible Expansion Extension

New version Geekworm embedded armor aluminum alloy Heatsink (P165-B) is only designed for Raspberry Pi 4 Model B 1GB/2GB/4GB/8GB Version, embedded heatsink with 11mm thickness. User manual, refer to Geekworm WiKi search P165. 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; It is strongly recommend to use CPU grease to get better heat dissipation;. Only equipped with 4pcs M2.5X5+5mm 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.

Minor adjustments needed

Like other reviewers, they noted that the bottom of the heatsink, which sits over the USB-C and HDMI ports, makes contact with those components before the heatsink support legs meet the circuit board come into contact. .020" heatsink in the area of the USB-C and HDMI ports, but it was still not enough that the heatsink's support legs made contact with the board, causing the board to warp slightly in that area. To solve this problem , make a 0.050" indentation on the bottom of the heatsink where

Pros
  • Great design
Cons
  • Minor issues

Doesn't fit, won't touch vital chips

Following the instructions of attaching thermal tape to only the RAM chip and attaching the heatsink resulted in the RaspberryPi being bent. With or without thermal tape on the RAM chip, the heatsink doesn't make contact with the CPU or the bus controller, the hottest components on the RaspberryPi board that need to be cooled. Also, the supplied power connector on the fan is not compatible with the recommended position for connecting to the board.

Pros
  • Great for outdoor activities
Cons
  • Repair

Just what I needed for computers and accessories

I use my Raspi 4 as a file server and DNS ad blocker 24/7. I removed the fan that comes with this sink and installed the whole thing in a wooden box with a more powerful exhaust fan and vent. Works great for passive cooling. I used graphite thermal pads to keep them in contact with the RAM, Wi-Fi chip, USB bus and CPU. It doesn't go above 48C. I need an adapter so I can connect a 40-pin ribbon cable to the GPIO. It fits fine, but you might end up with a ribbon cable after filing the sides a…

Pros
  • One year trial
Cons
  • Some bugs

Minor adjustments needed

As other reviewers noted, the bottom of the heatsink makes contact with those components over the USB-C and HDMI ports before the heatsink feet make contact with the PCB . I was able to file about .020" of the heatsink around the USB-C and HDMI connectors, but it still wasn't enough to get the heatsink support legs in contact with the circuit board, causing the board to warp. little in this area. Geekworm needs to edit .050" on the bottom of the heatsink where the USB-C and HDMI ports are…

Pros
  • Amazing
Cons
  • Could have gone for a newer model

Takes a bit of effort but works well with the right fit

As others have said it takes a little practice to get it to fit properly. It was what I expected so I only deducted one star but I wasn't expecting THAT much grinding. The tiny piece next to the camera cable connector needs to be removed completely or it will hit the connector. The area around the power connector also needs some sanding. Once you get the hang of it, it works pretty well and keeps my Pi below 40C, but I got about the same temps from regular heatsinks and a 20mm fan. Slightly…

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous
