+Drive the fans from **dashboard-it → "Server" view → Fans**. The view is
+deliberately minimal — it shows the current **fan speed** (% of capacity +
+absolute RPM) and two controls:
 
-Any non-`auto` override **auto-reverts to `auto` after 60 min**
-(`automation.r730_fan_mode_auto_revert` on ha-sofia), so a forgotten override
-can't run the fans wrong indefinitely — **unless you engage the Fan Lock**
-(`input_boolean.r730_fan_lock`, toggle on the same view). While locked the
-override persists indefinitely and a "🔒 FAN CONTROL LOCKED" banner appears on
-the view so you remember to unlock; unlocking restarts the 60-min timer. The

+- **Override %** (`input_number.r730_fan_manual_pct`) — the fixed fan % to hold.
+- **Lock — freeze speed** (`input_boolean.r730_fan_lock`) — turn the algorithm
+  off and hold a fixed speed. Toggling it **ON** snapshots the *current*
+  commanded % into Override and switches the daemon to `manual`
+  (`automation.r730_fan_lock_freeze_current_speed_resume_algo`); toggling it
+  **OFF** switches back to `auto`, resuming the presence curve. Fine-tune the
+  held % with Override while locked. A 🔒 reminder appears on the view while
+  locked.

+Under the hood the daemon still reads `input_select.r730_fan_mode`
+(auto/cool/quiet/manual) + `input_number.r730_fan_manual_pct` each loop; the Lock
+toggle just drives `mode` between `manual` (locked) and `auto` (unlocked).
+`cool`/`quiet` remain valid modes if set directly (via the entity) but are no
+longer surfaced on the simplified dashboard. `CEILING` (83 °C) still overrides
+everything → Dell auto, **even when locked**. A stale non-`auto` mode left while
+*unlocked* still auto-reverts to `auto` after 60 min
+(`automation.r730_fan_mode_auto_revert`, now a dormant safety net). An HA change
+is applied within one daemon loop (~15 s).
