I'm guessing the fan control module is shot. Any idea on the price and is this a common thing failure?

It should not overheat if you use clutched fan. Check coolant...
make sure it is 50% coolant/50 water or max 60 coolant/40 water. I use 60/40 combination with the old (blue) coolant.
It could also be the water pump. Check those two (coolant and water pump).
If you don't turn on the A/C, the secondary will only turn on at mid point between normal middle point and overheat point (slightly to almost overheat point).

I checked my invoice
Electric fan not turning:
- 1 relay switch, $23.60
The part is most likely 100% marked up.
Sorry, I don't know how much they charged me for labor. The cost is hidden among other stuff.

Did you see the price for the fan clutch?
Maybe you should replace the clutch-driven fan with an electric fan. You'll lose less hp, and the electric fan will be quieter. UrS4 sells a nice-looking kit.

But don't count on the aux fan when it's idle.
At idle, when the temperature is reached (near overheating) the aux fan'll kick in BUT it'll only running very slow. So, don't count on it (it may be too late to cool your engine).
changing the clutched fan to EFK is better from my point of view (like moriboundman said).
Disadvantages of clutched fan:
1. VERY HARD to open (!**~!%##)^%@!!!!!!)
2. loss HP
3. You need to open more screws if you're changing the timing belt.
