If you read the blog about the development of the board. This is one reason
they made their own board. They really worked on the heat sink and it seems to
have really worked.

Subject: [raspberry-vi] Raspberry Pi 400 and temperature
Hello folks
I thought this might be of interest.
I have fired up my new Raspberry Pi 400 for the first time this morning and
left it running for a few hours.
I set up a cron job to run:
vcgencmd measure_temp
Every ten minutes and write it to a file.
Results show the Pi 400 running very cool indeed. In fact cooler than my Pi 4
4GB runs naked with a heat sink on the SoC. It is hovering around
24 degrees Celsius. My Pi 4 usually hovers around 48 when it is idle.
Admittedly the Pi 400 is idle and not doing anything much. It is running
Raspbian Lite, so not even displaying a desktop. But since it is over-clocked
already, the cool temperature is quite impressive.
The integral and very large internal heat sink is obviously very good.
Not so keen on having to press Fn+F10 to switch it on.
I have fixed small stick-on tactile bumps (here in the UK we call these
'bump-ons') above F4, F8 and F10. So easy to find F10. But still have to use a
light detector to see if the green LED is alight.
Have not plugged in a USB audio dongle yet and started SpeakUp.
