Hey everyone.

I recently bought this Western Digital 2TB WDC WD20EARX-00PASB0 Caviar Green.
The HDD is quiet as advertised.

But I have something bugging me about the temperature. While the drive is idle, the temprature is ok.
But when I start watching any movie stored on it, the temperature goes high like 46º C!
I used 3 different softwares but none of then found it's RPM and Buffer size
I wonder about buffer size because when the movie is playing it keeps reading the drive like it have no buffer at all! Hence the increase in the temperature.
It is stored in a external dock (eSata) and there is no reason to heat like that.

Thanks for any comments and suggestions.

The green drives do heat up nothing you can do there but put it in an enclosure with a fan. I have one that got way hot died after 2 years. The buffer is mostly for writes so pulling a 2 gig movie off a hard drive that has a 16 or even 32 meg buffer does not stop drive reads at all. So basicly temps are normal put a fan on it.

I highly doubt your drive is causing such a high temperature.

What is your ambient temperature? That can affect HDD's temperature.

How big or small is your case? If it's small it might not have enough circulation.

Do you have enough case fans on your case? Does it have a proper push/pull set up?

How is your case wiring? Is it sloppy? That can cause bad air circulation with sloppy case wiring.

Is there anything under your HDD to cause it to have more heat being applied to your HDD?

Hey there!

Thanks for the replies!

The case:
http://www.ebay.com/itm/New-Sarotech-2-5-3-5-External-C...
(temperature goes the same either the lid open or closed)

The environment by the case/cpu is dry, clean, normal air circulation.
Ambient temperature is around 31º.

Anyway, why it won't show buffer sizer and rpm?

Is 45º C is normal? Will it harm the HDD lifetime?
I was thinking about getting one of these: http://www.ebay.com/itm/Portable-Super-Mute-PC-USB-Cool...

Ambient temperature is high. Around 35c is when even fans cannot push air to become cool enough.

Not sure why it wouldnt show buffer size - probably a program error. As for your RPM - i believe it is a variable RPM drive since it's a "Green" drive, and I believe goes anywhere from 5200RPM -> 7200RPM (varies).

I can't see that link, but if you can cool your HDD more, it should last much longer, heat is not good for any electronics.
