> when we heard that there was a passive cooling solution for the Raspberry Pi which would keep the temperatures low enough to prevent thermal throttling at stock speeds, we were a little dubious. They shouldn't have been. I have the Argon 40 case for an RPi4. I've overclocked the core to 2.0GHz, and with 100% passive cooling, no fan, it does not thermal throttle at all. I've pegged it at 100% CPU use for an hour with no throttling. The chip runs hot, but it's not a top of the line CPU that needs active cooling. A good sized chunk of metal will cool it just fine.
