My 4 TB drive certainly running at the upper edge, like 44 C at last measurent (Crystal Disc info) at 24 C ambient (usualy does never exceed 30 C, i live in cold country) . However, i never expected it to be good, there is close to no space and bad ventilation at my system, just to many drives in to little space. However, that drive only needs like 7-8 W, its hard to guess that it could truly overheat by its own energy.
According to manufacturer it can "stand" a internal HDD temp (simply the value measured by HDD) between 0 and 60 C, so im still far away from that value. Funnily, a HDD doesnt enjoy below zero, which is understandable because the moving parts might get frozen.
Some other people say: Every C does decrease lifetime by some guessed value... which i find stupid. That might be true for overclocked hardware but not for HDD. Because the main issue isnt the material being vulnerable to increased electro migration, its main issue is to prevent the sensitive mechanical parts from having wrong adjustments, its movement is the main issue.
My own view is: The temp, as long as it doesnt exceed the value which is considered "safe" by the manufacturer, its not that big of a deal. Much more important not to have high temperature differences all the time. Which means to stay as stable in temps as possible = highest lifetime. So a drive doesnt enjoy turning it on and off all the time (power on cycles is a limited value). More worse than temp itself is the difference in temps. That can destroy its mechanics because material is having different size at different temps, when to much changes, it can lose its accuracy. Finally the drive may fail working properly.
I think, generally when they say 24/7 drive they truly mean it like that. Optimized for 24/7 and probably having highest lifetime doing so. That may count for every HDD, however, the cheaper one usualy are running colder (less peformance) and may not be that vulnerable when not done that way. So, running colder, yes it does help because lesser difference vs. ambient. But as long as temp is very stable, i feel like it could be at 60 C for years without issues. However, be aware, that theory also means that when the drive is cooled down to 5 C (in some freak systems) and ambient is like 35 C, its not necessarely better and its same such as having a ambient of 24 and a drive running at 54. All whats important never to leave the temp-range from the manufacturer and staying as close to ambient as possible.
Finally: Just want to know, whats safe to use? All im looking for is a sufficient (simply safe to use) value not a astounding one. If its to high i will try to make some measurement in order to reduce heat. Means im probably gonna make a heat shield with some sort of copper plate and some sink-like attachment. Will certainly find a solution. Every bit does count, when i can lower it 5 C its big success. I just can tell, its most challenging to build small systems with high end hardware, nothing is more challenging than that and i will have to make many mods i guess. On the other hand, its not fun not to have challenges, they are the sort of stuff able to give me advancement in the understanding of many matters and new improvements which comes with it.
Most important not to make "guessing"; when there is a view, backup the view by a scientific approach (why is it like that?). Other stuff cant be trusted and is nothing more than guessing.
