Doesn’t sound normal to me. But those newer CPUs can scale the frequency extremely fast, so looking at the numbers in Task Manager might not be too meaningful.
Didn’t have any heating/fan issues on a 13th gen Framework Laptop 13 in either Windows 11 or Linux. But haven’t exactly looked at the clocks either. And don’t have access to those notebooks currently.
But the hardware vendors can mess up either thermal paste/cooling in gerneral, or force weird clock behavior via the bios/efi/acpi tables.
I don’t have evidence. That’s why I added the rumor in the title and mentioned it on the end of the post. It just never happend before in the youtube app like this. Could be pure coincidence. The only thing that concerns me is the language they use. It’s very suggestive they’ve done this on purpose. At least it sounds this way in German.
I doubt that a clean Windows 11 install causes issues. If anything it has better power management on 13th gen.
