Hard Disk Sentinel
Q&A Knowledge Base
My SSD reports unknown or constant temperature
Some (especially older and/or cheaper) SSDs may have no working temperature sensors at all, the the manufacturer simply did not add it. In this case, the temperature value of the SSD may remain unknown (Hard Disk Sentinel displays a ? on the Temperature page).
If we inspect the S.M.A.R.T. page of such SSDs, there is no "Temperature" or similar attribute present (or if present, its value may be 0). In contrast, if we check a different SSD model and/or a modern hard disk drive, we may see one (or even more) Temperature attribute(s).
Some SSDs (to prevent displaying this "?" in Hard Disk Sentinel), always provide a fixed, usually fake (not valid) number as temperature. The most common values are 32, 40, 48 Celsius, regardless of usage. The temperature value should rise upon disk activity of course for any hard disk drive or SSD.
In this case, if you check the Temperature page, you may notice that all temperature values are same: the highest, lowest, current values are all the same, which confirms that the SSD never provides real value (which should decrease/increase with usage).
In this case, I always recommend to ask the manufacturer about the situation. Even if SSDs can work and tolerate higher temperatures better than hard disks, temperature monitoring is still important and hopefully they can confirm why the real temperature information is not provided by the device.
