High idle temps

I got tired of being deaf in one ear and took my 80mm Tornado off my Thermalright SK-7 and put a standard Enermax case fan on it...my temps increased dramatically, from 35 C idle to about 47-49 C. I know a couple degrees are from dust on the heatsink (can of air ran out just as I was starting to clean) but I'm thinking there is a solution with improving airflow. 2 rear intake fans (I know it sucks but the front bezel on a stupid case prevents front intake), one side intake and a top blowhole.

With those 4 fan positions can anyone suggest a better configuration?

The real question is will high idle temps like this decrease the lifetime of the chip, especially if it's this hot over high uptimes?
 
You could keep the Tornado and add a Vantec Nexus fanbus. They're relatively cheap now @ Newegg (circa $19 for the cheapest model) and handle the Tornado fine. Even @ the lowest setting the Tornado still moves some air & is a lot quiter. ;)
Plus, you can fine tune the noise level/ temps to find a balance you can live w/.
As far as your airflow goes, you can move to higher cfm case fans, but once again you'll add noise (the Nexus can help w/ that too, though).
The cpu temps are fairly high for idle, unless that's the on-die sensor (which always is higher by a good bit on my Asus a7n8x boards). Unfortunately the on die temp sensor on the AMD cpus is not known to be the most reliable reading known to man...so all you can know (if it is, indeed on die) is that your temps went up. To be honest, it's all about balance---balancing out how much noise you can take vs. @ what temps you are, personally comfortable w/. If you're not experiencing instability or heat related problems, then don't sweat it. As far as longevity, I would bet that obsolescence will claim your chip way before heat. ;)
Finally, if that is an on-die reading (vs. the in socket diode or thermistor) then your temps are not bad @ all.
