I have a seagate 250 GB HDD almost 3 years old (8 MB cache). I was worried about those temperatures because games are crashing & even firefox crashes many times. Besides the 500 GB WD green I bought recently & put inside a closed case (using as external) never goes beyond 43 degrees after half an hours usage.
The ambient room temperature should be around 33-34 degrees in afternoon-evening & 30-31 degrees in morning. I do not have gfx card, so inside of the cabinet is not that hot. even the processor is just 2.0 Ghz AMD Athlon X2. Also, my friend's HDD (same model) is reaching just 42-43 degrees even after an hours usage. His house is close, so temperatures are similar.
Those are the things which caused me to worry. But now that I know that it's not that high, I'm not worried that much. Also I have a backup of almost everything i my new HDD, so even if it fails I won't lose data & it is also under warranty. So no worries.
