My 2011 CAAD 10 is BB30. After bringing it home from the LBS, I reinstalled the bearings along with a new crankset. Didn't use Loctite with the bearings.

4500 km (2800 mi) of group rides, sprints, and climbs later it is still creak free. The bike has been ridden in the rain several times as well. The only cleaning I do on the BB is flossing out the grit and grime near crank/spindle with a rag.

Proper installation is key to getting it creak-free. I guess was also lucky to have a good BB shell and properly fitting bearings.
