The point is that the RPi4 runs much hotter than previous models---seems the inevitable fate of getting more powerful chips onboard. The Internet is all atwitter at the thought that changes to the microcode will help but early indications are that this will be only marginally helpful.
I hate the thought of a fan but I'm thinking active air cooling will become necessary if I stuff one of these babies into my cabinet.
Sadly the RPi4 remains a unicorn---heard about but never seen. USA distributors have been crushed by orders. I placed two orders the day of the launch but I guess I'm already in the second or third tranche.

I'd like to see temps < 60C during normal operation as an audio player. Thats roughly a 15C reduction from stock!
To get there it will probably take a correctly attached passive CPU heatsink plus a bit of under-clocking / under-volting, plus the firmware changes. I would probably use a razor thin layer of thermally conductive epoxy to attach the heat sink rather than that thick thermal tape.
