How much quicker? Quicker enough that I shouldn't run them at full speed?

No, they're designed to run at and are rated for full speed. Fan specs often list an average lifespan. Noctua for example lists a MTTF (Mean time to failure) of > 150,000 hrs for their NF-F12.

Higher speeds will wear the fan out more quickly.

Depending on the fan(beQuiet, Noctua, and a few others are low enough rpm that it doesnt matter) running them at max rpm will cause auditory defects to crop up quicker long term, even if the motor and bearing dont fully fail.

*shrugs* They'll last till the warranty's up. But I have 5 Noctuas from 2011 that still work today and have run at 80% mostly nonstop. I'm halfway convinced that Noctua's MTBF is just the minimum they'll guarantee the fans for because they're too lazy to take the time to fully run them into the ground. You see something similar with most drugs in pill form. They have a purported expiration date, but for the vast majority of them that's only the date the pharma companies tested the pills out to not the date at which they significantly lose effectiveness.
