 ### Secure Boot

+As discovered by *DEvil0000* the Linux Thermal Monitor ([thermald](https://github.com/intel/thermal_daemon)) can conflict with the purpose of this script. In particular, thermald might be pre-installed (e.g. on Ubuntu) and configured in such a way to keep the CPU temperature below a certain threshold (~80 'C) by applying throtthling or messing up with RAPL or other CPU-specific registers. I strongly suggest to either disable/uninstall it or to review its default configuration.
