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.
