I know about this 'Smart' option, but I believe that these values can be unreliable in certain situations. Any option in the Smart features can be configured by the controller manufacturer and the production company to appear however they need it to be shown to you. For example, there have been consumer reports stating that certain SSD models using a particular controller tend to overheat, leading to performance throttling and premature flash chip degradation. This information has spread across the internet, causing the manufacturers to urgently address the issue to counter the declining reputation of their product.
How can this situation be resolved? If it's a hardware design flaw that can't be perfectly fixed through a firmware update, an honest company like Intel might choose to recall the problematic products. However, other brands with a history of poor practices, such as Samsung and Western Digital, might only release firmware updates. These updates could adjust the offset of the temperature sensor (actual temperature 80 degrees Celsius, displayed as 65 degrees Celsius, offset -15 degrees Celsius), reduce the frequency at which the controller core and flash memory operate, and modify the duration of full-speed mode to address the overheating issue. This is a common practice in the industry, and even many reputable big brands do the same.
