The article discusses the impact of high absolute temperature on the longevity of drives, however from my amateur knowledge the range of temperature during a day is also an important factor.
I always assumed that having a stable 40°C is better than a drive constantly swinging between 20°C and 40°C, so I am surprised that the article only mentions alerts on reaching a high threshold.
