--- Comment #63 from Sydney Meyer (syd.meyer@gmail.com) ---
Hello all,

perhaps this is the wrong place to ask such a question, but after reading many
sites on the interwebs about the issue, i am left with the impression that most
people (me included) do not actually understand the implications introduced by
turning on/off knobs like "acpi_enforce_resources=lax". Also, i read a lot,
mostly unclear, comments about "hardware damage" and therefore would like to
ask, what is actually the recommended way to go about this with the situation
as it is now? Is this issue perhaps only relevant for manual fan control,
because with or without "acpi_enforce_resources=lax" and the nct6775 kernel
module loaded, the system appears to adjust the fan speed for the appropriate
load either way and there aren't any noticable differences between CPU temps
either. So i guess my question basically boils down to this: Is there actually
something to worry about, apart from not beeing able to see/control fan speeds?
I just have become a little worried now with all the contradictive information
out there, also read (on phoronix) about this [1] and this [2] a few weeks ago.
This is a Asus X570 Gaming-E Board with a Ryzen 5950X CPU. As a regular user,
am i going to fry my little computer by running Linux on it?

I understand that nobody will guarantee anything, of course, i just felt this
might be a good place for a qualified answer, because, obviously, i don't
understand any of this low-level stuff.

Thanks a bunch.
