This photograph was composed less than 15 minutes ago to portray the heat sink which has now been installed on the Broadcom SOC integrated circuit

In a passive set up the heat sink does not do much, the temperature drops just with a couple of degrees and the order of two to 3° C

With a fan spinning air on the heat sink the temperature drop is significant

From my experience with electronics I know that heat sinks designed for Passive cooling have longer fins. For example the heat sink that I used to repair my National monochromatic television 12" when I was a kid, had very long fins and the heat sink was about as tall as my thumb {8.5cm}

That analog Integrated Circuit controlled almost everything in the television, which made the circuit board quite Compact and easily maintainable

Corrections made with the compliments of @AnachronistJohn I entangled the SOC with the WiFI IC since it's from Broadcom, which also makes network ICs

The Broadcom Wi-Fi Integrated Circuit in the Raspberry Pi5, proves something that we have known from the ATX PSU {power supply units} for years. When such a system is powered off significant parts of it are still drawing current.

In my experimentations with the system, where the power supply circuit runs in a similar fashion as the legacy ATX systems, I had powered it off after having run the SBC without active cooling. The Raspberry Pi5 is a robust machine, that can run without any active cooling. The temperature difference is on such a level that is totally within the tolerances of the Integrated Circuits in the SBC.
Over here it operates @ 60+° C. The idle temperature is of course lower.

With a soft power off, the Broadcom Wi-Fi IC still remains warm to the touch, even after a couple of hours. This is also the IC which receives an Aluminum cooling block when you buy a official Raspberry Pi case for your SBC

This temperature is a warning for you not to mess with components that need a total power down when you need to work on the machine.

Thanks to the SBC distro I've been brought back the the light & powerful LXQt DE. It's a breeze and a whif of elegance in blistering speed to work on the Raspberry Pi5.
I will install LXQt on my X86 system also so that machine can Fly like an Eagle

Thank you for the excellent work programmers!

That is quite a bummer. I wonder what the reason might have been for the programming team to revoke that possibility.

The current ways of preparing the Headless Install through customization, are of no value to you because your OS / computer cannot run the imager, which brings you in a chicken egg situation
