Good temps for HDD's?

I recently added some extra cooling in my WHS system to drop the drive temps from 50c down to 39-40c. Is this a good temp range for 1Tb 7200rpm Hitachi's?
 
I would consider that safe, my RAID 5 array runs 29c for the bottom drive and 37c for the top drive. Anything under 40c is safe, i would not want to run them 24/7 above 45c for any reason.
 
Thanks. It was bothering me when they were up in the 50's hence the cooling.

I actually 7volt'd the rear extraction fan along with adding a quiet front Hiper fan blowing directly onto the drives to cool them off. The system is now quieter and cooler, so I think I've won.
 
I've never had a (healthy working) HD ever run over about 93°. Right now my WD740ADFD is showing 80° & 75.2° (from two different programs) and my HD103SJ is showing 75° by a program and 81.3° by direct contact thermistor on the spindle shaft bearing area. Both have fans blowing across them.
 
Heya,

HDD's are actually built to run quite hot. Hotter than you may be comfortable with. The 40'sC area is really fine. 50's is not super, but if you dropped a fan in and lowered down into the 40's you're now golden.

Very best,
 
Look up the model specifications. A common operating range is 0-60 degrees celsius, within which failure rates do not vary. So, excess cooling only increases power consumption and noise. Just allow for fluctuations based upon intensity of usage and uncontrolled environment.

Just putting a fan on a HD so it will be cooler isn't going to increase its power consumption or noise. Now if you're close to 32°F, that may be another story (if that's what you mean be "excess cooling").
 
I don't follow you. Running an unnecessary motor (fan) wastes power and creates noise with no benefit. Excess is lowering the temperature to any degree within operating range -i.e. if that is 0-60°C and adding a fan reduces the highest temperature from 50 to 40, then that is a waste.

Yeah, then I misunderstood you. I thought you were saying that by simply cooling a HD causes the HD's power consumption and noise to increase.
