The Crucial Storage Executive software will report both the current temperature and the highest lifetime temperature, in Celsius, measured by a sensor on the SSD. The specified operating range for most Crucial SSDs is 0 C to 70 C (or 32 F to 158 F). Any temperature recorded above 70 C could void the product warranty, so temperature should be monitored periodically. If temperatures regularly run above 65 C, corrective measures such as improved ventilation and fans are advisable.
