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

Nice heat-sink. I used some generic 'white' heat sink paste on the Raspberry Pi 4 B and this heat sink lowered the CPU temperature by 10 degrees C. So it works well. It is well made and has a nice finish. I have the PI mounted to the backside of the display, and I was able to drill out the threads of the heat-sink and use the supplied 12mm screws to attach the heat-sink to the existing display standoffs. This is really nice as many of the heat-sinks need much longer screws to mount this way. But here the supplied screws worked. See the picture below that shows the supplied screws being used to secure the RP-4 B to an existing Display Mount. Bottom line: I would buy this again.

Fits well, keeps the pi cool without a fan, and easy to install!

Impressive heat sink for my pi 4 picoreplayer. I needed one that would allow me to add a digi hat and this one worked great. It lowered the temp by 10 degrees inside a vented plastic case, the heatsink was also 5 degrees cooler than using that same vented case with a fan. Thus, I could cool my pi 4, keep the case I like and eliminate the fan. In my case without fan, the temp stays right at 50 ° C, YMMV. I did use thermal grease and it would have been nice if they had included a small dab with the heatsink.

I bought this heat sink for my Silverstone CS-PI02B. I wasn't thrilled with the tiny heat sinks included with the CS-PI02B. So I bought this since it looked like it would fit inside of of the Silverstone CS-PI02B, and it does! You just need to buy longer screws to secure this heat sink to the logic board via the threading on the bottom of the Silverstone CS-PI02B case. If you don't have a screw size checker, the size is M2.5-0.45. Amazon has this size, fortunately! 16mm length is right about what you'll need to ensure a good tight seal.

Love this heat sink fits like a glove, even got it to fit inside a standard Cana kit plastic case by trimming and filing a few places in the pi case, didn’t even have to remove the fan.

Good quality Heatsink for Raspberry Pi 4. I have added small fan on 3.3V and used good quality thermal paste instead of included thermal tape. That might helped with possible contact issues, although I could not tell if there is an issue with that or not. I was running the load tests for 1 hour and it was keeping the CPU and GPU between 45C-49C (with no overclocking). During the normal load, it keeps temperature on 37C.

Being bigger, it disperses the heat further away from the chips. Looks boss

Bought this to avoid using a fan - works great fanless.. of course even better with fan.

Fits the board, dissipates heat well, no fan needed. Thermal pads included, screws are included. Use it on Raspberry Pi 4B as Home Assistant hub.

Received with no holes punched in it.
