hard disk operation temperatures

google rocks out at 80-83F iirc; they must have the science down.

I would suspect the fluid dynamic of airflow and stable temperature and humidity is more important than actual temperature.

I am old school so i feed the boxes 68F air to the drives (in the front) which exits at 78F (alot going on in there). this raises to 78F which exits at 88F (not good) - but i am working on it.
 
Im planning to improve the air flow, my case is old and it is just a basic office box, but I recovered a big fan from an old server and I want to place it in a side to get some air in. But anyway, my room is very hot at summer, probably I cant avoid getting disks to 40C even at nights.
 
30C-45C is the comfy zone for HD's, if you believe the google study. Below 30C is not good. A peak of 45C is acceptable.

Electronics generally don't like wide temperature variations. Shutting your system down (to save it from heat) is causing the temps for all parts to range from room temp to operating temp. That in itself is a problem. I see far more failures in my systems that get shut down regularly than in the systems that run 24/7. Yes, this is purely anecdotal evidence.
 
So, if I buy one of the new WD that reports 60C as the peak temperature, I will be fine if I keep it around 45C. That makes me feel better, thanks!
 
I would keep your HDs under 50C. Anything higher, and in my anecdotal experience, they start to get sector errors. Preferably around 35-40C.

If below 30c is not good, then I have problems. My WD runs at 26 almost all the time. Most hard drives I have dealt with have been below 30. I do not believe that at all.

26C is room temp-ish, which means you have a lot of airflow over the drive. Believe what you want to believe. I'd say you're trying too hard to cool the drive, but I prefer warm (but extremely silent) systems. Although, I also strongly believe (as stated above) that constant temps are also very very very good for drive longevity. I think that temp changes a mostly ignored by most users.
