 <!-- PARAMETERS -->
-## Parameters
+## Paramètres
 
-All parameters are optional as they have default values (including default iDRAC username and password).
+Tous les paramètres sont optionnels car ils ont des valeurs par défaut.
 
-- `IDRAC_HOST` parameter can be set to "local" or to your distant iDRAC's IP address. **Default** value is "local".
-- `IDRAC_USERNAME` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "root".
-- `IDRAC_PASSWORD` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "calvin".
-- `FAN_SPEED` parameter can be set as a decimal (from 0 to 100%) or hexadecimaladecimal value (from 0x00 to 0x64) you want to set the fans to. **Default** value is 5(%).
-- `CPU_TEMPERATURE_THRESHOLD` parameter is the T°junction (junction temperature) threshold beyond which the Dell fan mode defined in your BIOS will become active again (to protect the server hardware against overheat). **Default** value is 50(°C).
-- `CHECK_INTERVAL` parameter is the time (in seconds) between each temperature check and potential profile change. **Default** value is 60(s).
-- `DISABLE_THIRD_PARTY_PCIE_CARD_DELL_DEFAULT_COOLING_RESPONSE` parameter is a boolean that allows to disable third-party PCIe card Dell default cooling response. **Default** value is false.
+**Connexion iDRAC :**
+- `IDRAC_HOST` : peut être défini sur "local" ou l'adresse IP de votre iDRAC distant. **Défaut** : "local"
+- `IDRAC_USERNAME` : nécessaire uniquement pour un iDRAC distant. **Défaut** : "root"
+- `IDRAC_PASSWORD` : nécessaire uniquement pour un iDRAC distant. **Défaut** : "calvin"
+
+**Contrôle dynamique des ventilateurs :**
+- `CPU_TEMPERATURE_1` à `CPU_TEMPERATURE_4` : seuils de température en °C. **Défauts** : 30, 40, 50, 60
+- `FAN_SPEED_1` à `FAN_SPEED_4` : vitesses des ventilateurs (0-100%) correspondant aux seuils. **Défauts** : 10, 30, 60, 80
+- `CPU_TEMPERATURE_THRESHOLD` : seuil de sécurité au-delà duquel le mode Dell par défaut est activé. **Défaut** : 70°C
+
+**Autres paramètres :**
+- `CHECK_INTERVAL` : temps en secondes entre chaque vérification. **Défaut** : 60s
+- `DISABLE_THIRD_PARTY_PCIE_CARD_DELL_DEFAULT_COOLING_RESPONSE` : désactive la réponse de refroidissement Dell pour les cartes PCIe tierces. **Défaut** : false
+
+**Logique de fonctionnement :**
+- Si la température CPU ≤ `CPU_TEMPERATURE_1` → vitesse `FAN_SPEED_1`
+- Si `CPU_TEMPERATURE_1` < température ≤ `CPU_TEMPERATURE_2` → vitesse `FAN_SPEED_2`
+- Si `CPU_TEMPERATURE_2` < température ≤ `CPU_TEMPERATURE_3` → vitesse `FAN_SPEED_3`
+- Si `CPU_TEMPERATURE_3` < température ≤ `CPU_TEMPERATURE_4` → vitesse `FAN_SPEED_4`
+- Si température > `CPU_TEMPERATURE_4` → 100%
+- Si température > `CPU_TEMPERATURE_THRESHOLD` → mode Dell par défaut (sécurité)

 <!-- TROUBLESHOOTING -->
-## Troubleshooting
+## Dépannage
 
-If your server frequently switches back to the default Dell fan mode:
-1. Check `Tcase` (case temperature) of your CPU on Intel Ark website and then set `CPU_TEMPERATURE_THRESHOLD` to a slightly lower value. Example with my CPUs ([Intel Xeon E5-2630L v2](https://www.intel.com/content/www/us/en/products/sku/75791/intel-xeon-processor-e52630l-v2-15m-cache-2-40-ghz/specifications.html)) : Tcase = 63°C, I set `CPU_TEMPERATURE_THRESHOLD` to 60(°C).
-2. If it's already good, adapt your `FAN_SPEED` value to increase the airflow and thus further decrease the temperature of your CPU(s)
-3. If neither increasing the fan speed nor increasing the threshold solves your problem, then it may be time to replace your thermal paste
+Si votre serveur revient fréquemment au mode Dell par défaut :
+
+1. **Vérifiez la Tcase de votre CPU** : Consultez le site Intel Ark pour connaître la température de boîtier maximum de votre CPU et définissez `CPU_TEMPERATURE_THRESHOLD` à une valeur légèrement inférieure. Exemple : pour un Intel Xeon E5-2630L v2 avec Tcase = 63°C, définir `CPU_TEMPERATURE_THRESHOLD=60`.
+
+2. **Ajustez les seuils de température** : Modifiez `CPU_TEMPERATURE_1` à `CPU_TEMPERATURE_4` selon votre environnement. Exemple pour un environnement plus chaud :
+   ```
+   CPU_TEMPERATURE_1=35
+   CPU_TEMPERATURE_2=45
+   CPU_TEMPERATURE_3=55
+   CPU_TEMPERATURE_4=65
+   ```
+
+3. **Augmentez les vitesses de ventilation** : Adaptez `FAN_SPEED_1` à `FAN_SPEED_4` pour améliorer le refroidissement :
+   ```
+   FAN_SPEED_1=15
+   FAN_SPEED_2=35
+   FAN_SPEED_3=70
+   FAN_SPEED_4=90
+   ```
+
+4. **Si les problèmes persistent** : Il peut être nécessaire de remplacer la pâte thermique de votre serveur.
