Hi Colin, It's called q-fan. It comes with the asus bios. https://www.youtube.com/watch?v=qIBLJ7nG3KM Pardon me if the terminology i use may or may not be correct. Essentially, it has a wizard to tune/calibrate the speed (or voltage) to cooling fans as a function of temperature at different MB location and cpu. They also supply a ASUS Fan Xpert 2 for Win OS. https://www.youtube.com/watch?v=BdxlUEG1IZc. I think thermald function is similar to q-fan and fan Xpert2.
Questions: 1. Given that thermald cannot read _TRT and _ART, am i correct to say that thermald is not managing the thermal state of my system? 2. Also, does this mean that thermal management in my system is only performed by ASUS UEFI/BIOS with no active involvement from the OS and Ubuntu? 3. Does this mean thermald is a redundancy on my system and I can uninstall it w/o harming my system? Appreciate your advice and help to answer these questions.
