Thermald is relatively new (Intel made) fan modulation system designed mostly to (1) keep boost frequencies running as long as possible. (2) keep your fan from constantly turning off and on. Your system has its own fan speed curve & power envelope that works no matter what the system is doing. Not having thermald does not somehow cause your system to overheat (for example many AMD systems aren't support) Turning thermald off is Intel signally that they have an on-silicon/in-kernel/in-EFI/partner guidance method that now does as equal or better job.
