Concerned Hard Drive Temp
I am getting slightly worried about my hard drives temperature.

Using munit-node says at the moment been running at 42approximately, the highest it's got to is 52 degrees (both degree's Celsius), is this worrying at all? should I start to think about cooling my server down (I am backing it up so it's doing a ton of IO calls at the moment to be honest).

Am I just getting over concerned about this and worrying about nothing?

AFAIK spikes are OK but prolonged exposure to excessive heat may lower MTBF. What makes machines easy is that you can check things so there's no need for decisions based on "guessing", "thinking", "worrying" or other fuzziness: as goes for most HW the vendor has documentation showing a preferred operational temperature range.

The maximum temperature of HDDs is around 60 C. However, 52 is getting close.

What about other temperatures ? Is this inside a case ? If all temperatures are high, consider cooling options.

Actually, 60C is a typical maximum spec for the environmental temperature. It is expected that the internal temperature will exhibit some rise above the environment. I've got one drive that I felt was overheating in a poorly designed external enclosure. Displaying that drive's lifetime temperature excursions with "smartctl -l scttempsts" shows that it hit a lifetime high of 67C, but had zero instances of being over its temperature limit. That drive does have the usual 60C max environmental temperature spec. (I do have that drive in a better enclosure now.)
