Yeah, I used to use a noisier fan with a higher air flow that kept my cpu temp ~ 38C. The noise annoyed me so I swapped it for a quieter fan, and the temperature now idles around 50C going up to 55C if the heating is on and Im doing some encoding or something.
I think people put far too emphasis on the temperature of the CPU, like cram83 said, AMD say they are fine running with temps up to 70C. As long as the system is stable then why worry about the temperature? Set an alarm and a shutdown temp in the bios and then turn off motherboard monitor!! Then you wont know the temp and you will be happy!!
I guess there is the issue of the lifespan of the chip, but if it means I reduce the lifespan of the chip from 10 years to 7, then who cares, I seriously doubt I will be using the same chip in 7 years.
