Ooh, this is interesting. I've not bought any pi 4's yet because I don't want moving parts on them. If this means passive heatsinks are practical, I might retire some 3B's.
- mhandley 5y agoI've had a good experience with using a passive heatsink case on my Pi 4s. It's not lightweight, but there's a lot of thermal mass and plenty of surface area for cooling. https://thepihut.com/products/aluminium-armour-heatsink-case-for-raspberry-pi-4 https://thepihut.com/products/aluminium-armour-heatsink-case... I've got one sitting here driving some animations in chromium on a spare display, currently running with a load average of 1.1 (so not working flat out on all cores, but doing a moderate amount of work). CPU temp is 49C, and the case/heatsink is just pleasantly warm to the touch.
- InvaderFizz 5y agoPassive has been practical for a while with the Argon or Flirc cases.
- NortySpock 5y agoI've been getting ~50C temps at 10-20% load using a Flirc case for the RPi 4. (21.2 C ambient in my basement; technically the RPi is in a large cupboard but I don't recall that being noticeably warmer.) After compiling a rust program on 4 cores last week for nearly an hour, I think I hit ~72C on the CPU very briefly if memory serves, but temps dropped immediately any time rustc let off the gas.
