Does the RPi4 heatsink work with Pi 3B?

Will the Aluminium heatsink for the RPi4 work with a Raspberry Pi 3B or 3B+? thanks! trying to keep some RPI 3Bs and 3B+'s working in a remote tropical location.

Part no. COM3100

It should work, just be careful how you attach it so it doesn’t touch anything its not supposed to touch. You’ll want to position it so the thermal sticky pad is right over the Pi 3B’s SOC.
I use these ones.


Mainly because they are compatible with the 3B Pibow Coupe cases.

thanks! we are using our Pi’s where it can get up to 40 plus C so need as much cooling as we can manage (just north of Brazil, and inland)

I think I misread your first post somehow? I thought you were talking about this.

You may have fitment issues with that Pi 4 heatsink Case on a Pi 3? Sorry for any confusion I may have caused.
