iMac 27 - Temperatures Hardware

Hi,

I'm a bit concerned about the temperatures inside my new iMac 27" i5. Especially my hard drive (WD Caviar Black 1TB). After about 2 hours of normal computing it is 52 degrees celsius. Last night I imported 30-40 minutes of video to my iMac and the temperatures after that are

HD Macintosh 56
CPU 53
Ambient 22
GPU Diode 68
GPU Heatsink 67
Mem Controller 55
Optical drive 50
Power Supply 2 67

56 degrees Celisus on a HD is very much. According to WD the maximum working temperature for the harddrive is 60 degrees. I am uncomfortble close to that limit without even pushing the computer.

WDs own info:
Operating -0° C to 60° C
Non-operating -40° C to 70° C

And according to http://www.codinghorror.com/blog/archives/000748.html

"Hard drive temperature is arguably the most important temperature to monitor in your computer. If you regularly see temperatures of 45C or higher on your drive, consider improving airflow in your case. If you don't, you've substantially increased your risk of hard drive failure or data loss."

Should I be concerned?

I have the exact same problem. In fact my imac has crashed twice. It's a 27inch i7 less than 2 months old. It gets so hot its painful to touch the aluminium body. Within 3 weeks of purchasing the product while working on documents in photoshop the imac suddenly spontaneously shut down so I basically lost 4 hours of photoshop work. It then spontaneously restarted but after the chime and before it could even boot up to the desktop it spontaneously shut down again with the screen going black. This "automated" process occurred non stop until I got a little scared the hard disk would be damaged and disconnected the power supply cord. Contacted apple care and they said after a motherboard and power supply replacement it should work fine. However, within 3 weeks of that replacement, the exact same issue resurfaced this time while I was rendering a 3D image. The imac has now been taken in by an authorized service provider for repair but I am skeptical and afraid that it might crash again even after repair. I have major presentations coming up in may and can't afford to have the imac crashing on me again. Anyone having the same problems? Kindly advise. Thank you.
