I'd agree (and that's what I did) except here I'd suggest "maybe wait until they solve the core overheating issue".

Mine is idling at 64°C now that I took off the official cover; with the cover on, it was idling just below the CPU throttling point of 80°C, which meant that almost any computation caused it to start intermittently locking up.

Odd, mine is idling at 49 C in a 21 C room. This is the 4G version running fully updated Raspbian without the desktop (one of the updates fixed the USB controller using a lot of power at idle).

Mine is 4G too; I installed heatsinks on it couple hours ago and it now sits at 61°C idle, with an external HDD attached (but not under I/O load) to USB 3 port. Slightly better, though arguably still ridiculously high.

Apparently this will be fixed with a PCIe firmware update, they're just figuring out the best way to roll this out.

It looks like it'll be mitigated (https://www.tomshardware.co.uk/raspberry-pi-4-firmware-updat...), but not necessarily fixed- making a difference of a few degrees. Active cooling makes a huge difference, which is why it baffles me that the official case has no ventilation.

I did not buy the official cover, but a cheap top/bottom (but not side) acrylic case that included a fan, and also applied 3 heat sinks which came in the basic kit that came with the pi from canakit. It idles at 47°C and can browse "new reddit" at 59°C. A samba share its hosting causes it to run at 59°C during file transfers to an external SATA drive connected to the USB 3 port. I'm pretty happy with it considering all the complaints about heat issues. Only issue I've had so far is that you cannot reliably power more than one external hard drive with this. A second one will need its own power adapter.

There was a firmware update, so make sure you applied that. Might help bring the temps down a bit.

AFAIK that firmware update isn't up yet, and won't be for weeks.

Try sudo rpi-update

There was an update that made a small improvement in idle temp. https://www.cnx-software.com/2019/06/29/new-raspberry-pi-4-v...
