Initial 100 decreased to 49 means that sometimes the drive is hot enough.

I've been under the impression that 100C was the absolute temp limit

Do not confuse normalized values (100 means shiny new, 0 means really old or damaged) and RAW_VALUE. For some drives smartctl -x may report history of temperature measurements, but I think summer values are already unavailable.

and it not been over 36C that I know of according to gkrellm which s set to monitor that stuff in real time. Right now nothing in the system is north of 32C, might get to 36C

71 <-> 29 °C and 49 <-> 36 °C mapping might be possible, but I would expect higher temperature for 49.

I read up on the manpage.
New -x version for this SSD attached
