Here is a screenshot of the CrystalDiskInfo SSD and hard drive information software. As with the previous SSDs from Micron and Crucial, respectively, the SSDs were equipped with a temperature sensor that can be queried correctly under Microsoft Windows 10 and Windows 11. Alternatively, you can query the Crucial SSD temperature with the Crucial Storage Executive software. Idle temperatures of over 40°C and load temperatures clearly over 50°C are not uncommon for M.2 SSDs. The two T700 PCIe 5.0 SSDs would throttle from 81°C without a heat sink and switch off from about 90-95°C and are thus absolutely dependent on cooling! We will go into more detail about the maximum NVMe SSD temperature including thermal images on the Crucial T700 Practical testing page.
