Erreur régulière sur PowerEdge R420

​Bonjour,​

​Serveur configuré sous Linux.​

​Des messages d'erreur reviennent régulièrement (toutes les 3H/4H) indiquant un problème de surchauffe des tous les processeurs et un abaissement de leur fréquence de travail.​

​Puis retour à la normal :​

​Le phénomène est bref mais les conséquences assez lourdes car le serveurs hébergent de nombreuses bases de données.​

​Merci par avance de m'aider à résoudre ce problème.​
