https://bugzilla.kernel.org/show_bug.cgi?id=204807 --- Comment #64 from Hans de Goede (jwrdegoede@xxxxxxxxxxxxxxxxx) --- Sydney, I understand that all the discussion can be somewhat confusing. It should be perfectly safe to run Linux on your computer (but as you said no there is no warranty), by default Windows also does not come with any software to monitor the nct6775 sensors. So when installing Linux without making any changes your computer will run the same way as with a pristine (no extra sw installed) windows install. Under Linux you will even be able to monitor the CPU temperature using the CPU's builtin temp-sensors. What does not work is monitoring other temperatures, voltages and fan-speeds. Nor controlling fan-speeds. But typically a modern motherboard will automatically control the CPU fan speed based on temperature, without needing the OS to do anything; Also most users typically use their computer for other things then to monitor the computers temps and voltages. Matthew rightly advises against using "acpi_enforce_resources=lax" because that opens races between the firmware and Linux which could result in writing to another superIO register then intended. This can definitely lead to e.g. stopping the fans even though the CPU is running hot, which is not good but all modern CPUs have builtin overtemp protection, so at the worst the system will simply shutdown (1). Theoretically this could also lead to worse outcomes, such us changes your CPU or RAM voltage which could damage your hardware. I am aware of at least one semi-related case where RAM got seriously overvolted damaging both the RAM and the CPU, this was not with a Super-IO solution though, but with I2C attached sensor probing. 1) Repeatedly overheating your CPU to where it automatically shuts down is not good for your CPU's health though and will likely shorten its lifetime. TL;DR: Don't use "acpi_enforce_resources=lax", otherwise running Linux should be safe and everything should work fine. -- You may reply to this email to add a comment.
