The helper wrote 0xC01C8F07 from a zero-filled 28-byte buffer with only the target at byte 5, but SET forwards bytes 2..27 to the controller, and re-sent that blind write every 15 s. Every write is now GET, change byte 5, SET, GET again and compare (fan_servo.c); a failed GET writes nothing and a profile change beyond the target is logged once. The watcher reads the target every tick (default 2 s, was 15) and writes only when the system put its own back (a fan-pattern switch on game start or exit), counting restores; after 5 failed writes in a row it stops and reports fan_guard=failing until the next set. An old fan_reapply.conf (its bare number was never read back) that says 15 moves to 2 once. Targets go up to 85 C (fan_map too); a target above the console's own is refused (fan_above_stock). HW_TEMPS adds fan_restores, fan_last_restore_s, fan_guard, fan_filtered_c (8F09), fan_min_c/max_c and the profile as hex; fan duty is read as Q10 from 8F02 (it was scaled as 0..255).
