I think you need a kernel hacker rather than a Debian-user to suggest to 
you some boot parameters to try for that hardware, follows two very 
stupid questions:

- is the intel-microcode package installed?
- when Didier recommended the linux-image-rt-amd64 kernel after 
installed, have you rebooted the system and verified with the "uname -a" 
command that the fanless PC is running the real-time kernel?

Kind regards,
