OK !

/var/log/mcelog existe bien :

Comme vous voyez, il n'y a pas de dépassement de température critique contrairement à ce qu'affirme mcelog.

Le système de fichier est OK

Je pige pas et google m'aide guère :(

kern.log m'indique que le CPU3 (coeur n°4) est "above threshold alors que sensors : va de 75° à 85° (
