What are normal temperatures? My northbridge, southbridge, and the mobo "system" all seem to be at 47-53c no matter how much or little stress I place on the board. Any ideas why this is the case? I attached the little fan to the NB, and that dropped the temp a couple degrees, but things still seem hot.

I have the ASUS Maximus Formula SE for many months. My temps are very close to yours, slightly better because I have excellent airflow across the MB to cool the chips. My ASUS MF SE is equipped from the factory with a watercooling solution built in to the MB heatsink. I don't need it. My temps are fne (like yours which is normal).
The only way you could get lower temps on those MB chips is do something like this.
Like OP posted, his NB temps range from 47-53 C which is normal. These temps are fine and are what you should expect with your board. I suppose if you are an extreme OC'er pushing your system to to it's limits, a mod like that might be in order. Otherwise try and insure your case has good airflow across the MB. I have great case airflow with the ASUS Maximus Formula Special Edition and have similar temps as OP. My board is notorious for high NB temps and my SE comes with a water cooled capable NB heatsink. With the airflow I have established, I hardly need water cooling to control the temps on my system. Looks like a useful Mod if your up to doing the work, but it's not necessary unless you are in a situation I mentioned.
I have the same problem... my MB temp is around 52degrees(@idle)...
I have done the NB & SB re-"pasting". Helped abit with the N/SB temps.
My friend has the same MB and his one reads normally(around 28 degrees). He has a crappier case and I have a nice high airflow CoolerMaster Storm Scout, which is designed for gr8 airflow. I'm beginning to wonder if my sensor might be funky...
