Crucial M4 SSD drives do not implement a working thermal sensor logic. Most SSDs suffer from the same issue, since somehow SSD manufacturers don't think it's important to implement a temperature sensor. Some SSDs may have a temperature reading among the SMART attributes, but it either reports a constant zero Celsius, 1 Celsius, or a stuck value of e.g. 30 or 40 Celsius.
