A low-cost pack of heat sinks that are perfectly sized for the Raspberry Pi. Attach each heat sink to the Pi using the attached self-adhesive layer, and get your Pi running 10 degrees cooler.
I don’t believe there is enough clearance for the heatsinks between the Pi and the hat. I will note however that the POE+ Hat does include a cooling fan that should provide sufficient cooling for your Pi.
The largest heatsink is about the same size as the largest chip on the Pi Zero 2 as a sense of scale. They will work. We also have this large heatsink available for Pi Zero models.
The thing is that I don’t think that long heatsink will work in the pi zero case with the camera module because of the screws. I’m just wondering if this one works.
