Hi, I own 2 x 250GB Sata HDD's, they seem to run on an average of 45-50 degrees (HWMonitor) Is that a good reading for somthing thats been running for around 12 hours a day? Or is it too hot?

Thanks!

Temperature is of no importance to hard disks.

In fact, the review by Google told a warm disk lasts a bit longer.

Don't put a fan, it costs money, makes noise and shortens you disk's life.

Temperature IS MOST DEFINITELY a concern for hard disks. Google's study found that drives which are run at very LOW temperatures have a higher premature fail rate - there were a higher percentage of early failures, but the average life expectancy of the remaining drives run at those temperatures was the same.

But drives which are run at very HIGH temperatures DO have a shorter life expectancy - generally the higher the temperature the shorter the lifetime.

The optimal temperature seems to be around 40C. If your drives are more than perhaps 5C above or below this, then it's probably worth thinking about how to get them closer to that temperature.

45-50C should be fine. It's a bit on the warm side, but well within the acceptable range.

Hmm, well the side of the PC case is always open, so its dosn't really pack up on heat. Although the hard disks are right on top of each other, so I'm taking it pretty much heats one another up. And I can't move them elsewhere, or add a fan to it as there is no space. I'm going to put my 200MM desktop fan to the side of the case, where the HDD's are to see what it will fall too.

Aww, 3 minutes + 220MM fan = 50 to 35 degrees :)  Awesome :)  I wanna see how low I can go... Right now, I'm freezing my ass of with this thing on. I'll give it 2 more minutes.

I got it down to 24 degrees, but then my toes started to freeze of in this cold. So I switched them off, it went back up to 45 in around 30 minutes. Meh. Good little adventure :)

Actually the temperatures can increase with the case open if it means the airflow from the fans is no longer forced to flow over the drives.
