Are these temperatures safe??

[Noo]

All of my hard drives are running at around 40 degrees Celsius. I've googled the subject ( https://www.backblaze.com/blog/hard-drive-temperature-does-it-matter/ ) and while they say there's no correlation, the graph they provided tell a different story. On top of that, they only test the hard drives up to 30 degrees, and according to their graph anything above 30 degrees have a significantly higher failure rate. :hmm: yet there's no correlation :hmm:

The older google study indicated that anything below 40C was ideal and <50C was still acceptable.

CrystalDiskInfo on Windows flags anything over 40C as "caution."

I'd imagine you're probably fine. If you wanted to add an intake fan to get some cool air on those disks, it wouldn't cost much or hurt anything.

I think it varies from drive to drive. My WD RE4 was running at 50c before I pt it in front of a fan, it's now at about 40c. My other WD is close to 37c, but both my samsung drives are under 30c, with no fans to cool them.

Not a problem at all. Anything up to 50C is totally acceptable. Even 60C is still within the normal operating range. Study shows that the failure rate may increase when above 50C, however, this failure rate usually means nothing to a home user since we only run few HDDs. Random failure occurs at any temperature anyway. My computer run as a server 24/7 for more than 5 years now, some HDDs constantly run at around 50C, still no failure so far.

According to that study, Hitachi & Seagate drives fail at an alarming rate when temperatures reaches 31 degrees. As much as 3x the failure rate of 29&30 degrees...

I have 2 intake fans blowing directly at the hard drives right now, I can't imagine what temperature they'll be at without these fans.

I have a case full of hard drives and I like to keep them running as long as possible. It makes more sense to me to use a couple cheap fans than run the drives hotter and shorten the life.
I have seven hard drives; HGST, Samsung and WD, 15TB, none of the drives ever run hotter than 35°C thanks to a couple modestly priced, well placed fans.
The hard drives may be able to tolerate 40-50°C, but running them cooler makes more sense. Less heat is always better than more heat, no matter what the stats say.

I've run my computer in intensive heat so there shouldn't be a problem as long as there isn't a heat wave and you are running it all day you are fine.

Typical use is between 40-60 Celsius going below or above that a little won't hurt, just keep an eye out for the noise and give your computer a couple breaks here and there.

Jeepers... my desktop drives idle at 31-35C...

At 50C, some HDD brands like Hitachi will start to corrupt sectors. I've seen it happen.

Hitachi drives put off LOT of heat. I have melted plastic with them if not actively cooled.

Just make sure you have plenty of air going over them.

it's my home server running 24/7 :/

Ya your temps are fine. Better then most peeps,, so be happy with it. gl

The following study is from google. They collect data from more than one hundred thousand disk drives. And have interesting result.

http://research.google.com/archive/disk_failures.pdf

Paragraph 3.4 conclude that high temperature is NOT the major factor of disk failure (of course, not too extreme). In fact, temperature below 25C increase the disk failure rate a lot (Figure. 4), but lowest failure rate occur at around 40-45C. So, this is interesting that cooler is not always better. You should operate your disk at the optimum temperature range but not just as cold as possible.

Anyway, I am not sure if this study cover any Hitachi HDD. May be Hitachi HDD is hotter than the others and more sensitive to temperature. Also, this study just conclude that temperature is not the MAJOR factor of failure, but it can't tell if there is any relationship between disk failure and temperature.

Although this study is from 2007, I find it interesting that running a hard drive "too cool" can lead to premature failure. Perhaps more recent hard drive technology of 4, 5, 6TB and larger drives has eliminated any problems with cool running issues.
In my experience building and repairing electronic systems as well as building and repairing computers, I can't recall a single incident of damage caused by a cold environment. Of course, starting up a hard drive that's been in the freezer for a couple years might cause a little wear and tear, but you have to rule the extreme circumstances out of mainstream use studies.

I'd like to know where the sensors are placed and what they are measuring exactly. I wonder if that has any bearing on why Hitachi's report higher temps.
