I have 2 of them and they run at about 33C without problems, in an Antec Sonata II case. Highest temp I saw was 36C (using Speedfan to report temps from SMART data).
Just one off-the-wall suggestion - is your Power Supply beefy enough? The only reason I ask is that I had a problem with an external enclosure once that was underpowered, and it caused the disk (a different, IDE seagate drive) to overheat badly, until I replaced the external power supply.
Yes, a new big fast HD can overheat (whereas the unit it replaced may not have).
I bought one of those new Seagates - perpendicular storage right?
Or so I thought... when I got it home, my Seagate turned out to be a WD!
320GB, 16MB cache, SATA2 - just not the Seagate (no NCQ). New kid at the store. Man was I pissed off!
As it happened, I used it (it was a Sunday) and WTF, I have a Raptor for my OS anyway... so I used the WD, it would be fine for movie storage or whatever.
I'm reading ~34C for 2 drives in front of fan and ~38C for the 320GB above fan.
Well! I guess I'm glad I did not receive the Seagate after all, LoL :^)
But seriously, these HDs require:
-shielded round cabling
-great ventilation (incl. ~120mm rear case exhaust fan).
If HDs get beyond the upper 40's it is not good. No future in it...
But thank goodness HDs are very inexpensive, heheh
Another way to cool ur H.D effectively is to stuck thin double sided tape underneath a big heatsink then stick that heatsink onto ur H.D. If u got enough clearence above ur H.D. U can use any heatsink u can get ur hands on, since the H.D is flat on top so it's easy to stick the heatsink on. I stick 3 old PIII heatsinks on one of my machine that runs 24/7 to ensure that the H.D don't crap up under heat. Plus if u can get some ram heatsinks then u can stick 2 of those on the main chipset of the H.D and 1 on the cache (ram) of the H.D. This way u can make sure that it won't stuff up becoz it overheat, but still u can't make the H.D last forever, it's a wear and tear hardware. So expect some faults in the long run.....
