Looks fine to me. Those cards can take up to 105C. Keeping within 35C of that is pretty good, even though I'd recommend 40+ And yeah, 100% is better. Don't listen to all that about fan's life shortening.
See what they mean when they say ATIs are better? My 4850 runs at 42C idle and 60C load with automatic fan settings. Load temps. drop when 100% fan speed is set.
I run my vanilla 260 at 40% 52c idle and then turn the fan to 80% for gaming and never go above 68c. Tried the fan at 100% while gaming and was only 2c cooler than at 80%. These cards have a high thresh-hold for temps, as Rags mentioned.

and an intel q9550 at 2.8 ghz, with 4gb of pc8500,
