   Dear Maintainer,   
      
   What led up to the situation?   
   I upgraded my system from Debian 13.2 to 13.3. This included a kernel update   
   from version 6.12.57 to 6.12.63.   
      
   What exactly did you do (or not do) that was effective (or ineffective)?   
   I booted into the new kernel (6.12.63). I checked CPU usage using htop, which   
   was normal (under 5%), yet the fan remained at a high, constant speed.   
   I then rebooted and selected the previous kernel version (6.12.57) from the   
   GRUB advanced menu.   
      
   What was the outcome of this action?   
   On kernel 6.12.57, the fan behaves normally (turning off or slowing down at   
   idle). On kernel 6.12.63, the fans are not turning off.   
      
   What outcome did you expect instead?   
   I expected the fan management to remain functional as they were in the previous   
   kernel version. This appears to be a regression in the 6.12.63 build.
