Sensors agisce su una "infrastruttura" che è legata direttamente alla
piastra madre, è poco probabile che ci trovi le temperature dei dischi
(dovrebbe esserci un collegamento tra i dischi e la piastra madre e
che io sappia non ci sono controller che sono in grado di passare le
temperature dei dischi alla piastra madre).

Esistono gli smartmon tools che invece agiscono sui dischi e da cui
riesci a tirar fuori anche la temperatura, oltre a dati molto
interessanti come gli errori recuperati (che sono sintomo di disco che
sta partendo) o l'indicazione del disco stesso che sta per inchiodarsi
(tutti i dischi recenti hanno questa bella funzione).

Es: (nota -> 194 temperatura in gradi celsius)
