Schuler, good idea to start posting some results here so people can compare. Maybe your temp is a little high, but not much, I guess many of the Sagers out there are running hotter than yours. Try to vacuum clean the vents, doing that lowered my idle temp with 2 degrees
I have a 5660 with 3.06 GHz with HT enabled.
Normal (light) use is 50-55
When idleing for a while it drops to 47
The max temp I have measured is 83 when running CPU Burn for 20 minutes.
The cooling scheme on my 5660 looks like this, the fans have three modes off,medium and full.
full->medium at 58
medium->off at 47
off->medium at 58
medium->full at 70
The cpu cant get cooler than 47 because when the fans turns off the temp starts to rise again.
