Hi
Can you put a cooler in the front?
Or install the hard drives in every second slot
Are they 10k or 15k rpm drives? While I like lower temps as well, I have 10k rpm SAS drives in 2U servers in a 22 C data center that average in the upper 40s/low 50s. Some of the drives are 8 years old (hdfs test cluster where we just throw cheap or old storage at it). In my opinion, start/shutdown is harder on drives than those temps.
You need a fan from an air hockey table. I built a render farm in a PVC tube with 4 equal nodes using a single fan from an air hockey table. It just works SO WELL.. Each node has a CPU fan, naturally. But that's it. 4 node render farm through a tube, in a basement, with just an air hockey table fan on one end, and an 80mm case fan on the other end. At an angle, through a randomly placed basement window.
Yeah, it looks janky. But the numbers don't lie.
Just an FYI, an air hockey fan is like a server fan but larger. It WILL destroy your fingers or hot dogs or whatever else you stick in it. 1 end will be completely exposed when you remove it. The blades are metal and aren't meant to be messed with. You do this at your own risk! If you cut off parts of your body by being stupid, that's your own fault. I warned you.

They are 10k and since they are SAS the never spin down. In fact they sound like an old jet at take off but thats ok. Yes they are also 10 years old but reliable. I always tried to keed them around 36 to 42 degrees. Now they run at 52 to 54. So far they are holding up but I thought some additional cooling could help.

ha. Very inventive. I will check out their size. Thanks
The fans a strong but expensive. I can get 2 of my HDs for the price of the fan, so maybe I risk the temperature exposure

Where do you have these temps from? Is it just a feeling or did you read datasheets or talk to an engineer? Because for me as an electrical engineer 54 deg sounds not so much really.
The temp specs for Seagate for example says max 50/60 degrees.
If I am reading that right, that is case temperature in a very exact location. I would bet the case temperature is lower than the temp reported by smart (assuming that is how you are getting it).
Ah that is very helpful! Then you are absolutely right. But I think a few days or a week slightly above 50 degrees is ok.
Maybe you can change something in the server environment? Leave the rack or case open?
That case is designed to have 15K SAS drives in it with a max temp of 35 C. Seems odd they would run that high of a temp. What is the ambient temp? Is the case not getting airflow to it?
Are all four drives operating at the higher temp? The drive in the floppy space doesn't surprise that it would run at higher temp. No airflow there. The cdrom space could be replaced with a 5 1/4 to 3 1/2 adapter with a fan but 40mm fans don't do much in those units.
fwiw these guys report on a regular basis on hard drives, failures etc. makes for some interesting reading
For mechanical hard drives I would use Spindown, then the whole case is no longer so hot

Statistically poor article. Significant correlation alone says nothing about causality. A typical mistake.
