That is some serious power emission.

I would add a heat sink and a fan. I would definitely not put it into one of those tiny RPi shells.

Hi Chris

Where are these being tested.... 12 Deg for the low, either someone is being a scrooge and not heating the workplace in winter or these are right out of the fridge [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-26f4ca8e-1d8d-486e-abcd-ae87f70cae13/contentimage_5F00_1.png:16:16]

Thanks for this, I was just about to 3D print a slim case but now I think I will make room for a heatsink with good ventilation slots too [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-26f4ca8e-1d8d-486e-abcd-ae87f70cae13/contentimage_5F00_3.png:16:16] .

What do you think about this: BGA-STD-090 - ABL HEATSINKS - Heat Sink, For Ball Grid Array, Standard, BGA, 10 °C/W, 10 mm, 40 mm, 23.9 mm | Farnell el…

It is larger than the BCM chip, and guesstimates suggest it might keep the junction temperature below 120 deg C for ambient of up to 40 deg C if around 4 watts is being dissipated there. This is for passive cooling, and this wouldn't require a fan unless higher ambient is expected.

I liked that it is very cheap : ) and comes with the thermal tape. Should perform far better than the tiny heatsinks that come bundled with enclosures. Height is 10mm, I don't know if that breaks HATs from being usable or not.

BUT, I don't know if it could clash with other components, since it is larger than the chip, and the BCM.. chip looks very low profile : ( Also I might not trust this unless I cover with additional tape the exposed part of the underside of the heatsink.

Time for a heat sink. Did I read they throttle the processing of the SOC down when over 87 degree automatically?
